From the Founding President, Jay W. Forrester

Now, approaching the 50th year since initial work that led to system dynamics, we can look back on a half century of accomplishment and from that perspective consider the next 50 years.  In five decades, system dynamics has made excellent progress and is moving at a rate comparable to the early histories of other major professions. However, this progress represents only the first tentative steps toward a mature profession of social system design.

Some have expressed disappointment at what appears to be the slow progress in evolution of system dynamics. On the other hand, the field is moving at least as fast as have other professions. It is now 150 years since the founding of MIT; and engineering education is still unfolding. Some 125 years ago the Johns Hopkins medical school was founded; and medicine is still feeling its way. The Harvard Business School started about 100 years ago, and management education departments are still more like trade schools than true professional schools. It is time to start thinking about the next 50 or 100 years in the development of system dynamics.

The other professions, such as engineering and medicine, depend on educational programs as much as eight years in duration for advanced practice. In system dynamics, all education is still at the introductory level, whether in K-12 schools, undergraduate programs, or graduate schools. Nowhere is there a system dynamics education that builds cumulatively over even two years, to say nothing of eight years. Yet, it is clear that such depth is possible and needed, and will evolve. Until an extended education is available, the practitioners in business and government will lack the basis for appropriate system design. We also have an opportunity to provide a dynamic foundation under many other fields including medicine, political science, economics, and international relations.

Ideas for deeper insights and more powerful and extended educational programs exist close to the surface and are available for uncovering and development. Why do we not see more movement? Perhaps it is because the elementary understanding of systems developed in the last 50 years is so useful that people assume that is all there is to accomplish. Such is far from the goal. >We do not yet see emerging a stream of powerful, insightful, provocative, and publicly influential books on dynamics of subjects like inflation, social welfare, balance of trade, immigration, preemptive military intervention, epidemics, deficits, aid to developing countries, population growth, pollution, drug abuse, and medical costs.

After 50 years, the promise and vision for widespread understanding of systems is taking shape. The next 50 years should be devoted to bringing that vision to reality.

Packed boxes ready for the moveDear Members:

The Moving Sale And The Move: Thanks to everyone who participated in our one-time moving sale. During the months of March and April 2006 we sold 899 past issues of the System Dynamics Review and 181 past conference proceedings. We emptied close to 28 linear feet of shelf space that will not have to be moved again in September!

In preparation for the office renovation this summer, recently we spent some hours packing our desks and files, boxing the beer game supplies and all the printed materials. We had professional movers, but we still had a lot of work to do. Luckily, we were able to move our computers and files into the temporary office space the day before the big move, strategically avoiding the serious bottleneck at the one elevator in the building on Monday -- moving day. We were up and running by lunchtime. We will be on the second floor (instead of the third) in the same building for the summer. All our contact information remains the same during this time.

During the pre-move preparation time, significant amounts of bits and pieces, large and small, that had been stockpiled for years in all the third-floor offices started to appear in bins placed in the hallway! The hallway turned into a maze and a centralized source for all kinds of office supplies (although dusty, a bit out of date, and mostly metal instead of plastic), computer and phone cables, and other great finds. I have to admit I poked through my neighbors’ trash -- I needed a longer phone cable for the new space and found one in a junk bin.

All things considered, the move went very well; we have a great staff and everyone “chipped in.” We’ll be moving back again in September, so, if you have any boxes …

Past Conference Proceedings: A long-term project we are working on is to get all past conference proceedings on the web as open source material. As Jim Thompson, Policy Council Member, commented, “Proceedings are very important to scholarly research since they can be mined for the progression in the development of an idea.”

Paper copies of all the proceedings are archived in the Society office. The Istanbul conference in 1997 was the first time papers were included on a CD-ROM, and we’ve had electronic versions ever since. Conference proceedings from 1997 to 2005 are currently available on the Society Activities page, on the Society website.

Work-study students here at the University at Albany are manually entering titles and abstracts from the 1996 conference into a spreadsheet. Once this is complete, the tedious work of scanning the pages of the proceedings will be undertaken. With all the steps complete, we will link the titles to the scanned papers. The list of the titles and the abstracts will be searchable, although the scanned documents will not. We will continue this project until all the past proceedings are done and on the web! Do you remember all the conferences before 1997?

Request for News

Our plan to publish four issues of the System Dynamics Newsletter every year continues with this, the second issue of this year. Please send us your letters, news, photographs, and ideas to be included in one of the newsletters! Additionally, if you would like to contribute an article of interest to our community, please send your suggestion to the Society office.

All past newsletters, back to 1988, are available on the Society website under “Publications.” The recently added “Society Status Report of 1983-84,” and the conference keynote address of 1983 by Jay W. Forrester, capture some of our history.

Call for Photos (and other bits of history)

The 2007 conference will celebrate the 50th anniversary of the founding of the field. We are looking for historical event photos, documents of historic significance, any kind of artifact of interest to display at the 2007 conference.

Were you at the bullfight in Seville? Did you play soccer in 1981 in Rensselaerville? Do you have any photos, documents, or articles, or stories of notable events, conference or otherwise? There have been many remarkable occasions during the past fifty years, some momentous and some amusing. We are hoping that folks who have these bits of history will share them. If you have an item that could be copied and displayed at the 2007 conference, please send it to the Society office. Items may be in electronic form or hard copy. Credit will be given to contributors. This should be interesting and fun. Start looking through your old stuff! Thanks, Roberta

Chinese Chapter - Reflections on Organizational Learning (from Dr. Bing Wu, Chinese Chapter Representative)

On April 13th, 2006, Tongji University successfully hosted “Reflections and Discussions on Continuous Organizational Learning, Innovation, and Sustainable Social Development.”

This event was initiated by the Society for Organizational Learning (SoL) and executed by the China Chapter of the System Dynamics Society, the System Dynamics committee of the Systems Engineering Society of China, and Tongji Development Institute, Tongji University. It was sponsored by the All-China Federation of Trade Unions, School of Economics and Management, Tongji University, Shanghai National Accounting Institute, China Executive Leadership Academy (Pudong), the Enterprise Resource Management Research Center (AMT), Shanghai Mingde Learning Organization Research Institute, the China Business News, Wenhui Daily, the National Business Daily, Business Review (International Consulting Information) and more. The event was presided over by Dr. Bingcheng Wu, Representative of the China Chapter of the System Dynamics Society, Vice-Standing-Director of the System Dynamics committee of the Systems Engineering Society of China, and Vice-Dean of Tongji Development Institute.

The Society for Organizational Learning and Dr. Peter Senge emphasize that sustainable development can only go forward with reflections, because there is no ready answer to sustainable development in this unsustainable complex reality. Individual reflections, community reflections, and especially open group reflections with cross-cultural interactions will be requested in the future. Actually, reflections have been the core content of the traditional Chinese culture that contains individual and group learning, practice and tutelage. In recent years, both international and domestic experiences have already proven that without deep social reflections, the construction of sustainable development and the harmonious society cannot achieve substantive progress. Only the establishment of in-depth reflection and dialogue can help all stakeholders to achieve consensus and to form sustainable leadership in order to facilitate cooperation. The commencement is to gather the educational world, the business community, and the minority leaders of government and non-government institutions to form a common vision, expand a sympathetic chord and enhance coordination.

In order to make a contribution to creating a mature, harmonious and sustainable industry and commerce culture, the Society for Organizational Learning and the China Chapter of the System Dynamics Society sponsored this dialogue. The dialogue takes enterprise sustainable development leadership as a key point, and continues to impel enterprise leadership improvement in China by establishing a mechanism of multi-organization and humanities culture supporting the industry and commerce domain through official regulation, leaders attendance and the interaction way. The Society for Organizational Learning and the China Chapter of the System Dynamics Society hope to promote the comprehensive harmony of society and ecological system. Through this activity and a series of in-depth learning activities, the long-enduring impetus in the future is not merely "the reduction of environmental pollution" or "reduced unsustainablity." Therefore, the emphasized humanities and the society "environment" education is not only the tool for enterprise to improve its performance but also the goal. This goal is to construct "the circulation economy" for the benefit of both human beings and the nature.

The method of in-depth study is to combine those that historically proved true and those essences in traditional Chinese related to study and human development into the process of constructing the system thinking and teaching. Regarding human development and practice, there exist advanced theory and practice methods inherited from the past. Through cooperative research between tradition and the modern age, China and the world can construct a smooth and thorough communication bridge. A new Trans-Culture coordination and creativity will be formed.

Professor Qifan Wang, Fudan and Tongji Universities, President Elect of the International System Dynamics Society, President of China Chapter, President of Shanghai Association of MIT alumni, Director of Professional Committee of System Dynamics and the Systems Engineering Society of China, Dean of Tongji Development Institute, Tongji University, attended this conference. The conference also invited Prof. Kouqing Li, Vice-President of Shanghai National Accounting Institute, Deputy Secretary-General of APEC Finance and Development Program, Deputy Secretary of SNAI's Party Committee, also Deputy Director of Shanghai Serves of Economical Research Board; Prof. Jieren Xi, Deputy Vice-President of China Executive Leadership Academy (Pudong), Vice-President (concurrently) of Shanghai Social Science Association, President of Shanghai Leadership Science Association, expert in National Social Sciences Fund Project Discipline Appraisal Group; Dr. Qi Jin, the CEO (chief executive officer) of Anji-TNT Auto Logistic Limited Company; and other guests. We obtained support from the All-China Federation of Trade Unions, School of Economics and Management, Tongji University, Shanghai National Accounting Institute, China Executive Leadership Academy (Pudong) and the China Business News. Media coming to the scene to report included the China Business News, Wenhui Daily, the National Business Daily, Business Review (International Consulting Information), Xinmin Weekly (Wenhui-Xinmin United Press Group) and other authoritative and specialized media.

In his closing speech, Prof. Qifan Wang reviewed the previous discussions and two social events (including this one) that the Society, himself and Dr. Peter Senge have held about how to carry out the learning organization construction and impetus of sustainable development in China. At the same time, Prof. Wang also explicitly expressed the wish that the China Chapter of the System Dynamics Society and himself could establish the long-term cooperation requested from the International Organization Society and Dr. Peter Senge.

Special Issue of the System Dynamics Review celebrating the 50th anniversary of the field

The field of system dynamics was founded by Jay Forrester 50 years ago.  The 2007 conference of the System Dynamics Society will celebrate this milestone and, in conjunction, the System Dynamics Review will publish a special double issue (2 & 3) commemorating this achievement.  The special issue will consist of a mix of invited and contributed papers, and will both look back at our rich history and look forward to the next 50 years.  We particularly welcome papers and notes that review or synthesize important theoretical issues, application areas, modeling practice, comparative methodological issues, and educational developments.  We also encourage descriptions of exemplary applications and other developments that explore important paths for the future development of the field.

The issue will be edited by John Sterman with the assistance of a diverse group of guest associate editors:  Yaman Barlas, Bob Cavana, Pål Davidsen, Andy Ford, Peter Milling, John Morecroft, Nelson Repenning, George Richardson, Krystyna Stave, Linda Booth Sweeney, and Jac Vennix.

Papers should follow the journal's Guidelines for main articles and other categories of contribution.  They are subject to the normal refereeing procedures of the journal.  Inquiries about proposed papers are welcome; the guest editors will provide feedback on proposals. A two-stage procedure is to be adopted. Initially authors are requested to submit an extended abstract (two pages maximum). These will then be reviewed by the editors and selected authors will be invited to submit a full, Notes & Insights or Research Problems paper. Inquiries and extended abstracts should be directed to:

2006 Nijmegen, The Netherlands Conference Update

The 24th International Conference of the System Dynamics Society will be held July 23-27, 2006

For updated details, please visit the society website at: and click on the 2006 Conference button.


Conference Host
Methodology Department, Nijmegen School of Management, Radboud University Nijmegen, The Netherlands
Conference Partners
Minase BV, Tilburg, The Netherlands and Ventana Systems, Inc., Harvard, Massachusetts, USA
Nijmegen is the Netherlands' oldest city and celebrated its 2000th anniversary in 2005. The city offers historic sites and museums and borders beautiful forest countryside and polder landscapes, the unique low-lying terrains that have been reclaimed from water and are protected by dikes.


Conference meetings will be held at the campus of Radboud University in auditoria and parallel rooms. For coffee breaks and lunches the university restaurant and open-air bar are available. A range of accommodations, from a luxury spa hotel to bed & breakfasts and economical hostels, is available within walking distance or up to a 15-minute bus (or bike!) ride depending on the location. Nijmegen is a small, friendly city and very easy to navigate. Nijmegen can be easily reached from Amsterdam Schiphol Airport by a 1.5 hour scenic train ride. Information on travel and accommodations*, including a map of hotel locations and related information, is available at the Society website. There is also a Nijmegen "Survival Guide" with much local information. Go to the Conference Registration Information Section of the Conference webpage at

*NEW: Recently Radboud University has made available to our conference participants some "guesthouse" rooms. Mostly, these are ONE-person apartments available as of Saturday July 22nd for seven nights. The price (including linens and cleaning) is approximately 280 Euros. The entire week must be paid for; they will not rent the apartment for less than one week even if you do not need accommodations for a full week. Breakfast is not included. The apartments are within a short walk of the conference venue.

If your are interested in the possibility of renting one of these apartments, please contact Carolus Grütters at [email protected]. The apartments will be given "first come, first served."

The conference will bring together people from all over the globe working in system dynamics and systems thinking. Presentations by practitioners and world leaders in the field will cover a wide variety of topics.

The theme of the conference is "The dynamics of innovation in networks." Successful innovation requires enthusiasm and commitment from all parties involved. In complex issues that extend beyond the boundaries of a single organization, the network of stakeholders can be extensive. System dynamics in the Netherlands often takes the form of group model building. Academics and consultants alike choose to apply modeling in innovative projects on novel, complex issues that extend beyond the boundaries of single entities, reaching out to other individuals, groups or organizations. True to the spirit of system dynamics, group model building aims to capture the whole system, by involving all relevant constituencies and stakeholders in model construction. The theme of the conference reflects this involvement of multiple parties in making innovation work.

PhD Colloquium at Nijmegen

Dear students, faculty and all other practitioners,

At the 24th International Conference of the System Dynamics Society in Nijmegen, the 7th PhD Colloquium will take place as a whole-day event Sunday the 23rd July 2006.

The objective of the Colloquium is to bring together PhD students working on foundations, techniques, tools, and applications to system dynamics and give them the opportunity to present and discuss their research in a constructive and international atmosphere. The setting allows for common problems encountered by PhD researchers using system dynamics to be identified and discussed in more depth during dedicated workshops, thus providing a unique opportunity for learning among all attendants.

The participation of experienced faculty, practitioners, and others in the wider system dynamics community is a vital element for the colloquium to fulfill its objective and to provide a constructive and diverse atmosphere to the students.We warmly invite PhD students in the early to middle stages of their research to present their research proposal at the PhD colloquium. If you are interested in receiving feedback during this event from the senior researchers in our field, as well as from peers, please use the indications on the submission page of the PhD Colloquium website. Even if you are not presenting your work, you are more than welcome to join us for the whole day. The PhD Colloquium is a great event for meeting peers and exchanging ideas; please join us.

The format will accommodate about eight diverse plenary student presentations that have a clear research question and well defined open issues for discussion during dedicated workshops. Depending on the number of submitted proposals there may be a poster session in order to give all the students who submitted a paper the chance to present their work and get feedback.

The program for the PhD Colloquium can be found at:

Modeling Assistance Workshop

Jack Homer and Roderick MacDonald will facilitate the Sixth Annual Modeling Assistance Workshop.

Modeling assistance is available at the conference to enable modelers to discuss their specific modeling questions with modeling coaches. Modeling assistance opportunities include two public workshops, as well as the possibility of assistance at any time during the conference. Assistance is available for modelers with all levels of modeling ability, from beginner to advanced, with questions about a specific model that modelers are developing or studying, or to better understand something in a book, an article, or a software package. Modeling questions may deal with problem articulation, formulation of a dynamic hypothesis, formulation of a simulation model, model testing, or policy design and evaluation. Modelers should bring whatever materials they need to describe their question, including pencil and paper, books, posters, or laptop computers. Spectators are welcome to observe modeling assistance during the two public sessions.

To sign up or to coach, see detailed information at the conference website:

Sponsor News


Atrivé is glad to attend and sponsor the 2006 Nijmegen Conference. We're very proud to announce that a small paper of ours, initially presented at the 2005 European workshop, has made it into the special issue of SR&BS and into the 2006 Conference (session 147)! We'll bring some more colleagues in order to introduce them to the energizing world of system dynamics and we're preparing a somewhat provocative report on the messy problems of the Dutch housing market for early 2007. We are looking forward to meeting you all and to exchanging ideas on applying systems thinking and system dynamics modelling in consultancy and strategy processes.

Booz Allen Hamilton

Booz Allen Hamilton, a global strategy and technology consulting firm, has deep expertise in applying modeling and simulation for both public and private sector clients. System dynamics is a vital aspect of the firm’s extensive modeling and simulation toolkit. We use an integrated approach to help tackle complex problems in the areas of public health, international trade, energy, national defense, and budget and performance integration.

In 2006, Booz Allen worked with a large healthcare advocacy group to develop a simulation of pandemic influenza. The simulation combined system dynamics and agent-based modeling in an integrated approach to account for the spread of disease, intervention regimes, and a wide range of socio-economic impacts on affected populations.


Similar simulation efforts have been conducted to mitigate the impact of external shocks on supply chain networks, develop European transportation strategies, and simulate maintenance and repair on damaged military equipment under hostile circumstances. Booz Allen is committed to helping clients understand and shape their complex environments through an interdisciplinary approach that brings system dynamics simulation together with statistical, econometric, and agent based tools.

Established in 1989, CALIBRE is an employee-owned management and technology services company. For seventeen years, CALIBRE has built and delivered practical, timely, best value solutions to solve management, technology, and program challenges.


CALIBRE uses Systems Thinking to provide new perspectives and new solutions to our customers’ problems. Our models have been used in both federal and business organizations as management flight simulators and as learning environments. They have also been used in conjunction with balanced scorecards, in development of management metrics and as communication tools to educate stakeholders on policy decisions.


CALIBRE’s most recent Systems Thinking work is assisting the U.S. Army’s BRAC (Base Realignment And Closure) Office.  The Army is changing the structure of this organization from a decentralized, regional organization to a centralized one.  In this new structure all the Base Transition Coordinators will be co-located in Washington D.C.  As the Army is making this transition they need to ensure the new organization is process focused and Systems Thinking provided the perfect methodology to get all the decision makers on the same page around the necessary organizational structure, lines of communication with external stakeholders and data flows to make this transition successful.


Currently CALIBRE is a training partner with isee systems in the Washington DC/Northern Virginia area providing Systems Thinking and ithink workshops with a focus on Systems Thinking for the government. Our next workshop is scheduled for 18-20 September 06 and all are welcome to attend. For details see

Decision Dynamics, Inc.

Since its incorporation in 1979, Decision Dynamics, Inc. (DDI) has been providing satisfied government and commercial clients with the information they need to support effective decision-making.  DDI builds and employs sophisticated analysis tools that quantify the complex cost, performance and schedule tradeoffs among competing “what-if?” scenarios.  The tools, called “FleetSight” and “Workflow”, utilize advanced, proprietary techniques to bring the capabilities of system dynamics to the program analysis world. 


DDI LogoFleetSight, a program cost and analysis decision tool whose unique design brings the logistics, cost and engineering disciplines together in a coherent analytic structure.  FleetSight users define “what-if?” scenarios to include alternative management decisions, alternative assumptions about system relationships and/or alternative data points from different sources.  Unique to FleetSight is an analytical structure that allows for analysis of equipment impacts, such as availability, and cost projections, to be explored in a single, unified analytical context.  For conducting Analyses of Alternatives, it provides capabilities other tools can’t match.


WorkFlow, a process management analysis tool, offers users the ability to plan and manage large, complex projects and realistically simulate their performance over time.  Unlike conventional tools, WorkFlow incorporates the management processes that control the complex interactions among many interrelated production activities.


The WorkFlow model traces the consequences of cost and schedule of such “what-if?” scenarios as information delays, work quality, design/production changes and personnel shifts.  The model assists program managers and design engineers in planning and managing effective resource allocation among multiple tasking within integrated product and process development teams.


End-to-end Analytical Capability:  Using both FleetSight and WorkFlow, managers can look at prioritization of resources across the spectrum of potential alternatives, from material changes to the product, to changes to the supply chain and support philosophy, through repair process modifications.   


DDI has focused on building a solid reputation for building advanced analysis tools.  The Naval Air Systems Command, Naval Sea Systems Command, the US Marine Corps, the US Air Force, Northrop Grumman, United Defense, and the US Coast Guard Deepwater Program currently head the list of satisfied clients.


Our convenient GSA contract vehicle and strong reputation make DDI the vendor of choice when selecting program analysis tools.  Our product list includes:


-          Affordable leasing, multi-year, and multi-seat license structures for both WorkFlow and FleetSight;

-          Targeted on-site client training;

-          Focused consulting support for advanced applications.

Evans and Peck

Evans & Peck has been providing decision modelling advice to its clients for over 20 years.  We currently operate in Australia, New Zealand, China, Hong Kong and Singapore and are one of the few modelling consultancies that are positioned to provide localised support to firms throughout the Asia Pacific region.


In February this year the Sydney office hosted the annual Australian and New Zealand System Dynamics Research Colloquium.  This event was attended by a wide range of SD modellers from both research and consulting backgrounds.


Our new website was launched in March 2006. This website provides information and examples of our entire modelling capability including system dynamics, discrete event and agent based.


In May 2006 the Evans & Peck Sydney Office hosted the first Australian based AnyLogic training session.  This much anticipated session booked out very early and all that attended were treated to three days of intensive instruction in the new AnyLogic software and how it deals with various modelling scenarios.  We are currently investigating the possibility of running a second course later in the year.


Most recently the Evans & Peck Hong Kong Office, in conjunction with isee systems and Lexidyne, ran a three-day introduction to STELLA and iThink Course.  The course was widely attended, with delegates from South Africa, Singapore, Malaysia, Australia and China.  Given the success of this course it is intended to run an additional course in Singapore in early September. 


Following on from our recent training workshops, we are currently working with a number of NGO's in Hong Kong on a range of social and environmental policy issue models.


In amongst all the training courses and conferences the company has been running we have also been kept very busy on the consulting side.  We are currently working on assignments as diverse as gas pipeline maintenance in North Queensland, Internet service implementation in New Zealand, global workforce planning for a major mining company, port capacity planning in western Australia, national diabetes treatment strategies and national acute aged care strategies.


Forio Business Simulations

This past year, Forio Business Simulations has added a variety of new capabilities to its web simulation platform, Forio Broadcast 2.0.   


Broadcast is available in multiple versions. 


Forio is also offering a new complimentary service to its Broadcast Enterprise customers called "Hosted Enterprise." Customers who wish the flexibility of having direct access to a full web server and database that Broadcast Enterprise provides, but who don't want the IT hassle of setting up and maintaining the server, can now outsource that capability to Forio for no additional charge.  Specifically, Forio will (on request) set up a server running Broadcast Enterprise and provide basic maintenance free of charge.  (Note that hosting fees are billed to the customer at cost.)


More information on signing up for Forio Broadcast is available at


Forio's implementation services efforts continue to expand.  Forio has recently completed an engagement with the Wharton Executive Development Program to develop a detailed competitive multi-player simulation.  This simulation is an critical component of an intense two-week workshop taught by top Wharton faculty and attended by senior managers from around the world.   On a similar note, Forio has an ongoing partnership with the University of Michigan to develop and distribute the Big Picture Simulation (, a market strategy simulation that can be customized to fit a variety of business case studies.  Finally, Forio has recently completed the Oracle Lean Manufacturing simulation to educate customers worldwide on supply chain issues.

General Motors Corporation

Led by Dan Roesch, GM Strategic Initiatives (GMSI) is a staff of General Motors Corporation responsible for analyzing major strategic initiatives for the company.  Within GMSI, Phil Keenan leads the development of detailed quantitative models of the automotive industry or specific aspects of it, in order to more accurately assess the likely impact of potential new strategies.  Many of these are system dynamics and/or agent-based simulation models developed with the help of consultants Mark Paich and Lyle Wallis of Decisio LLP.


One recent project included building a management flight simulator.  Building on Vensim’s gaming interface capability, we developed a multi-player game in which senior executives played the roles of GM and key competitors during a future new product launch.  The real-time competitive nature of the gaming interface engaged the executives’ emotions and the power of the experiential learning led to important changes in GM’s real-life strategy.


We also developed an agent-based simulation of interacting consumers purchasing vehicles, calibrated with demographic and historical purchase data.  This combination of system dynamics with agent-based simulation seems promising because it enables modeling a wider array of behaviors, such as non-compensatory consumer choice.

Global Strategy Dynamics

GSD creates teaching materials and games to facilitate learning of strategic management for improving business performance.


Our Chairman, Kim Warren, was awarded the prestigious Forrester prize in 2005 for his book "Competitive Strategy Dynamics". This is the approach that underlies all our materials and business simulations and we are continuing to build on these sound foundations as we expand our range of products.


The most exciting development for 2006 is our Life Management Game: Jane Sloan We will be running a workshop using this simulation at ISDC 2006 and demonstrating it on our stand throughout the Conference.


Also during this year, we have made further developments to the content and added extensive teaching documentation to the LoFare Airlines Microworld which we previewed in 2005 – thank you to all who gave us their valuable feedback. We have also been kept busy on bespoke microworld development.


We have now translated our “Strategy Dynamics in Action” packs into Spanish and German and are expanding our network of individuals offering courses in the approach.

LISTO bvba

LISTO bvba is a niche consulting company active in science and technology management in the (nuclear) energy business sector. Our activities essentially relate to addressing energy market questions, technology foresight and roadmapping, assessment of science and technology development needs and strategic and comparative assessment studies. Our clients include utilities, R&D labs, governments and international organisations such as EC, IAEA and OECD. Based in Belgium, we are international in scope.


LISTO bvba makes extensive use of iThink/STELLA in modeling various aspects of the energy business sector. One of the largest iThink/STELLA-models ever, DANESS, has been developed with Argonne National Laboratory and simulates multi-regional nuclear energy systems composed of a variety of nuclear reactors and associated fuel cycles from cradle-to-grave while also addressing multiple sustainability dimensions (economics, environmental, …). This DANESS model is currently used worldwide by various organisations in assessing potential future nuclear energy system scenarios. More information is available at


Other models that have been developed relate to energy market dynamics, supply-chain models for fossil-based power plants, and others. As consulting and training partner of isee systems inc., we’re well placed to service the needs of utilities, R&D labs and (inter)governmental organisations by providing advanced system dynamics models using iThink/STELLA and isee.NET.

As sponsor of the System Dynamics Conference 2006 at Nijmegen (Netherlands), we would be very pleased to discuss your specific system dynamics needs in the energy business and/or science and technology sector. We are very much interested to initiate a Special Interest Group on Energy covering the various aspects from energy policy to science and technology aspects of energy market and technologies.


For further information, please contact Luc Van Den Durpel at [email protected],


Master Systems Inc.

Master Systems Inc. ( is an advisory services firm in its 21st year. We focus on improving the processes by which software is developed and managed. One of our principals, Stan Rifkin, completed his doctoral dissertation by writing the first simulation ever of Talcott Parsons' theory of action. Parsons was perhaps the best known American sociologist of the 20th Century.


What makes the simulation interesting to the system dynamics community is that it did not use system dynamics! Other famous and successful researchers had tried to use SD to model the theory of action and failed. Dr. Rifkin adopted discrete-event simulation instead and that worked; he used the organization as the unit of analysis, so the simulation enacts the way Parsons would describe action and change at the organizational level. You can see videos of the simulation and read the dissertation at

These are exiting times in The Netherlands. System dynamics and systems thinking are more and more recognized as valuable tools for managing in today's dynamic and complex business environments.  More projects, more initiatives and more research questions. In the meantime we are busy with the Dutch system dynamics community  to make the 2006 System Dynamics Conference a success.


We are looking to set up a Industrial Dynamics SIG in the Netherlands and are interested to discuss this during the business day of the coming conference in Nijmegen to tap in with international initiatives (if you are interested in this subject please contact Wiebe Cnossen ([email protected]).


From the project front we will give the spotlight  to a project we have carried out in the pharmaceutical world:


For a global company a large system dynamics model was made of the primary production and planning processes. Production processes were split into two parts: a customer-order driven part (packaging process) and a forecast-driven part (production process).

In the first phase of the modeling project a causal loop diagram was made of all logistic parameters and how they influence each other. In the second phase, the causal loop diagram was translated into a quantitative system dynamics model. With this model it is possible to simulate the effects of certain policies or business cases in a quantitative (and financial) way. Hereby it is possible to evaluate and support possible policy decisions. For example, what are the effects of shortening the production lead times: Are stocks decreasing? Do we need more or less employees? Will our delivery performance improve or deteriorate? And what will be the integral costs of this measure?


At this moment, the model is validated. The next step is to let stakeholders play with the model and let them run scenarios and discuss about the results of the scenarios, so learning and knowledge sharing will take place.


In our academic collaboration we are looking together with Tilburg University to set up a lab (Tiresias) focusing on supply network dynamics with emphasize on high-tech industries, pharmaceuticals and telecom. The seven waves of supply network dynamics as presented during the Oxford conference play a central role in this initiative (information available from Prof. H.A. Akkermans [email protected] or [email protected])

Management & Strategy Learning

More than five years has been elapsed since we became the sponsor of the International System Dynamics Society in Egypt. It is not an easy mission to be a sponsor; it is an important task with big responsibilities. During these past few years the time has gone by quickly while we in Mohaseboon® were always alone struggling in every and whatever available event or occasion, either in Egypt or in the Middle East, taking the opportunities for highlighting the Academic, Economical and Business Segments in our societies; explaining the importance and how far the benefits of applying System Dynamicscan go; why it is an advanced tool for developing the different types of Business Management Systems, and also what is relating to it's methodologies for solving the most persistent problems.


While speaking about Modeling and Simulation Technology, and due to the fact of our prolonged experience and existence in this part of the world, it is the time to confess that 80% of those who became more nearest to the issue had admired the idea in general without showing later any further interest or some progress toward discovering much of the concerned details. Transparently speaking, some others had rejected the idea for different reasons while very few were showing a real interest but according to their own visions. Hence we decided to do something new and tangible.


At the middle of the last year 2005; precisely after Mr. Walid S. Badr returned back from Boston, we had concluded several crucial meetings in Mohaseboon® for finding a new strategy to achieve our goals; the conclusion was to establish a new practical "Hand-On" track for The Management Learning by applying System Dynamics Methodology. During the scratch preparations of the said strategy, the first step was to divide the industrial sectors into major segments as per the nature of the commodities. Fortunately Mr. Badr was at the final stages of his MBA thesis at Maastricht School of Management, MsM. His case study was relating to one of the major industrial sectors; the Egyptian's Automotive Industry. At the same time, he made up his mind to implement System Dynamics to his project, so the idea was sparked and the name was born as AutoDynamics at that moment.


We in Mohaseboon® appreciate the great contribution of time and efforts by Mr. Badr, and have to congratulate him for recently achieving his MBA successfully. Also we have to thank him again for leading his brilliant team for their professional works during more than seven months while seeking to develop his personal project application version to be used commercially and copyrighted to Mohaseboon®.

AutoDynamics©, Why?


"The automotive industry is extremely sensitive to market dynamics whether internal or external. Such sensitivity requires highly qualified calibers to manage and run the business with all its complicated mechanism. "Off the job training" has become an essential for developing skills in addition to job experience. However, till now, most training tools are rather theoretical or maybe case based workshops. Time and dynamism were factors; though very important, yet cannot be covered in traditional training techniques. A simulation is an experiential learning exercise. The emphasis is on practice and active learning within a cross-functional business experience. The players provide the living detail through their own deliberations, actions and interactions with competitors and the market. The exercise represents a series of interconnected cases. Every decision period represents a new case, a new set of circumstances. The students do not need to role play. "AutoDynamics" is a realistic simulation application designed to be use either by PC (one user) or throughout a Server (multi-user) , which has been developed for the automotive industry. The model of the application was built by Vensim®"

AutoDynamics©, Topics Covered:

Demo versions and commercial licenses will be available at Mohaseboon® exposition in Nijmegen, next July 2006. For further relating details or information, e-mail Mr. Badr at [email protected] or inquire via general e-mail at [email protected]

Proverbs Corporation

Proverbs Logo

Sponsor news is short this year. We are very happy to introduce four great Hutchens/Gombert systems thinking fables translated into Czech language to our market.  Czech kids can make the first contact with systems thinking basics thanks to the elephant from Pabidi who also speak some Czech now. Nearly two dozen system dynamics newbies got successfully through Marek Susta's course "Dynamic Systems Modeling" at the Masaryk University. Development of models for neuroscience research at the Charles University Medical School led by Marek goes on. Lubomir Kostron is ready to retire; we are very thankful for his effort in introducing system dynamics to Czech and Slovak managers. The Czech edition of John Sterman's Business Dynamics is still not published; we are still looking for some sponsors - some 20% of expenses remain uncovered.

Proverbs book covers


Significant is an independent research and consultancy company in the Netherlands. We focus on helping organisations to translate their policy and strategy aims into an optimum business model and on equipping organisations to deal with the future effects of far-reaching socio-economic (policy) changes. We focus on the following subjects: Public Policy, Healthcare Markets and Welfare, Security and Justice, Immigration and Integration, Sustainability and Strategy, Design and Control.


System dynamics is one of the quantitative and operations research methods that we use in our consulting practice. Gaining insight in complex problems by reducing complexity is our goal. We apply system dynamics (almost) always in combination with group model building. The modelling process is at least as important as the content.


Together with the Radboud University of Nijmegen we are a partner of the Dutch Ministry of Justice for simulation modelling. We have applied system dynamics on several ex ante studies regarding changing policies and new legislation regarding the criminal justice system. To mention some of the examples: we built a simulation model of the criminal justice chain and analysed the effects of the more repressive policies according to the Safety Program (closing the prosecution gap of 40,000 cases). Secondly we evaluated the effects of new legislation on collecting DNA from certain offenders and a different completion of cases by the public prosecution. We also evaluated the trade-off between traffic safety, enforcement, the number of speed penalties and congestion. At this moment we are preparing a simulation model on forensic psychiatry (mental health care for delinquents). These projects are always a close cooperation between Significant and employees (system dynamics practitioners and experts with respect to the content).


For the business day (Wednesday) at the Nijmegen conference we have organized sessions on healthcare and public policy (especially the criminal justice system). We hope to meet you at the conference!

Sioo Inter-university centre for organisational change and learning


Sioo was founded in 1958 by the Dutch universities. The foundation has served ever since as a bridge between academic organization studies and organizational practice and change processes. Sioo has developed into an 'intellectual space and professional home’ for professionals who want to contribute to successful change processes and innovations in organizations and want to develop in the fields of organisation studies and change management. Sioo does not represent only one dominant school in this field. We believe that a diversity of viewpoints can coexist – and should continue to do so. At Sioo, people with a wide range of talents from a diversity of backgrounds meet. They share the ambition to contribute to business development and innovation and share a dedication to the development of their professional competencies and the ambition to contribute to business development. Of course they differ in their roles, positions, experiences and involvement in change and innovation processes.


Five tracks

Sioo offers opportunities for the development of competencies along five tracks:

§         Master and other training courses with open registration;

§         Coaching change processes in organisations;

§         Support in designing programmes for professional development;

§         Research and development;

§         Forum activities (symposia, workshops, conferences and publications).

Deepening, Expanding, and Developing

Sioo activities are characterized by a playful balance between theoretical deepening, systematic expansion in change methodologies and professional development. Sioo consciously opts for theoretical deepening in the knowledge fields of organisation studies and the management of change. Sioo exposes methods for researching issues of change and innovations in organisations and their environments and making these issues more manageable. Sioo stimulates professionals in their development by enabling them to reflect on their own actions, through deepening and expanding their own repertoire and by letting them choose a position in issues of change and innovation.

Dean, directors of studies and board of governors

Sioo does not employ their own faculty; the core of the foundation consists of a group of highly qualified directors of studies, each with their own special area of interest. Dean is Prof. Dr. Jaap J. Boonstra.

Sioo collaborates with many university professors, senior management consultants and managers and facilitates their role as ‘teacher’.


The Sioo Board includes: University of Amsterdam; Nyenrode University; Technical University of Delft; Twente University; University of Leiden; Radboud University of Nijmegen; University of Utrecht; De Baak, VNO-NCW Management Centre.

Ventana Systems UK

Ventana Systems UK are one of the partners collaborating in the InCoCo research project, a groundbreaking project that will enable companies to deliver integrated service solutions to industry.


The consortium of InCoCo was set up with the sense that a very high degree of complementarity and mutual support in respect of research activities and industrial goals can be achieved. This way, an interlinking of the various expertises intrinsic to the InCoCo consortium will provide top-quality results for the benefit of the industry and consumers in the European market area.

European, globally acting industrial firms from the manufacturing and IT sector have committed themselves to collaborate and to invest a substantial amount of human and financial resources in order to develop sustainable service integration in the manufacturing supply chain.


The challenge for increasingly global acting supply chains and service providers is to integrate and synchronize the services from external providers into the existing and continuously evolving networks and to successfully measure, control and evaluate the performance of these joint activities, both at the operational and strategic levels.


To facilitate collaboration between service and supply chain (SSC) partners, InCoCo aims to develop novel coordination procedures, enrich the frameworks for integrated measure of performances and finally develop decision support tools for this industry sector. Further, InCoCo will incorporate the results in these domains into a new pioneering framework for the development and management of the integrated SSC oriented production systems.


InCoCo's innovative vision is to fill this gap by integrating service processes into new S-SCOR model.

Ventana Systems, Inc.

Ventana Systems continues to pursue a variety of private and public sector projects while also moving forward with the development of Vensim.

On the people front Ventana is pleased to announce that Jim Hines, who is known to many in the Society, has joined us as a full time consultant. We have also recently hired Marios Kagarlis who has deep experience in detailed agent modeling making our scope of expertise broad.


On the project front our most public project has been the development of a National Airspace model for the Federal Aviation Administration and the JPO in the US. This model is being adopted to look at long-range plans for the development of infrastructure and the evolution of regulatory involvement in the airline industry. We have also become heavily involved in looking at issues in energy both from the public and private perspectives.


On the software front we continue to push the development of new tools to support new modeling activities while striving to make the tools of system dynamics available to the greatest possible audience. Planned releases include internationalization of the software into Japanese, Chinese and Portuguese, easing the language barrier for many.

The vendor of AnyLogic simulation modeling software is releasing long-awaited AnyLogic 6 (available now as Technology Preview). AnyLogic is a multi-method, multi-scale modeling tool supporting system dynamics, agent based and discrete event approaches. Being a full-powered system dynamics tool, AnyLogic enables the modeler to switch to a completely disaggregated level and model people, companies, projects, assets, etc. as agents having individual properties and behavior and interacting directly. Moreover, it is possible to model a part of e.g. a supply chain in process-centric discrete event style, and part in system dynamics style. Ability to combine approaches and replace model components with others implemented on a different abstraction level allows modelers to solve most challenging global business optimization problems. The new features of version 6 include:

  • Completely cross-platform solution (works on Windows, Mac, all major Unixes)
  • Much faster simulation engine
  • Highly efficient agent based modeling: run millions of agents on a standard laptop
  • Easy and efficient work with arrays with unlimited number of dimensions
  • Integration with GIS (Geographical Information Systems)
  • Multi-project development environment supporting teamwork
  • State-of-the-art user interface based on Eclipse platform
  • New OptQuest optimizer


AnyLogic is currently being used by over 150 companies and over 350 universities worldwide. Please visit
