From the Executive Director

Roberta L. Spencer

Dear Members:

As part of the celebratory events planned to commemorate 50 years of system dynamics, we set the 25th anniversary conference as a target date to complete two projects that were conceived at the 2001 Atlanta conference.

With the help of private donors who provided seed money, The Electronic Oracle by D.H. Meadows and J.M Robinson has been reprinted with new forewords from Dennis Meadows and John Sterman. This is a limited edition reprinting; the original book is very hard to find. Thanks to Dennis Meadows for helping with all the steps in this project.

Do you remember the Fireside Chat plenary session in Atlanta? Attendees were asked to send in questions for Jay Forrester to answer. George Richardson led the interview. The session was videotaped and is now available on DVD. The chat lasts about one hour; it is interesting and fun to watch.

Both The Electronic Oracle and the Fireside Chat DVD will be available for sale at a special price during the conference at the Pegasus Communications booth. They will remain available for purchase from the Society after the conference.

The Call for Photos has turned up some interesting snippets of the past. It’s not too late to send one in to be included in the display at the conference. If you have a document or photo that could be copied and displayed at the 2007 conference, please send it to the Society office. Material may be in electronic form or hard copy.

I look forward to seeing everyone at the conference. Please contact the Society office if we can help you with your conference registration or any other Society or membership issue. Warm regards, Roberta

Member News and Notes

The System Dynamics Society and the Center for Policy Research at the University at Albany recently welcomed three speakers who gave presentations about their system dynamics-related works.

In May, Frank P. Davidson and Kathleen Lusk Brooke presented an overview of their new book, Building the World: An Encyclopedia of the Great Engineering Projects in History. The audience enjoyed listening about how civilizations have created structures of immense scale, requiring such tremendous resources, that they might have been thought impossible. From the Taj Mahal to the Suez Canal, from Solomon's Temple to the Channel Tunnel, these feats of macroengineering are a testament to the creativity and foresight of architects, engineers, governmental leaders, lawyers, bankers, and diplomats. Macroengineering must rely upon the big picture methodology of system dynamics.

In March Professor Andrew Ford gave a talk on "Climate Change & Carbon Policy: Implications of a System Dynamics Study of the Electric Power System in the Western USA and Canada." The seminar began with a review of recent studies of climate change and the call for major reductions in the release of carbon dioxide (CO2) emissions into the atmosphere. The seminar focused on one of the more carefully studied proposals for carbon legislation in the US, S139, the Climate Stewardship Act of 2003.

Worcester Polytechnic Institute has announced the appointment of James K. Doyle as head of the Social Science and Policy Studies Department on July 1, replacing Khalid Saeed, professor of social science and policy studies, who will return to teaching and research full time after 10 years as department head. Doyle, associate professor of social science and policy studies, has been a member of the WPI faculty since 1992. His research has focused on judgment and decision making, risk perception and communication, and mental models of complex systems. Along with continuing to offer five undergraduate majors, and a unique master's program in system dynamics, Doyle says the department is developing plans for a PhD program in system dynamics.

Congratulations to Peter Milling! In April Professor Peter Milling, who leads the system dynamics group at the University of Mannheim, received an honorary doctorate in management (Dr. rer. pol. h.c.) from the Engineering and Management Faculty of Brandenburg Technical University at Cottbus. The citation for the degree specifically cites Peter's work in system dynamics and operations management. This is only for the second time in Germany (after Jay Forrester) that anyone has received an honorary doctorate for work in system dynamics. Heartfelt best wishes to Peter.

The 4th Systems Dynamics Workshop took place on June 11th at Fordham Business School, NYC. The theme of the workshop was Complex Information System Dynamics and Strategic Performance focusing on the management and business impact of information technology. Prof Nicholas Georgantzas (chair, Fordham) introduced system dynamics and discussed scenario-driven planning. Prof. Evangelos Katsamakas (program chair, Fordham) discussed the promise of System Dynamics applications in the field of information systems and presented research on the dynamics of open source software. Michael Raynor (Deloitte) presented his latest book, The Strategy Paradox. Other academics from Fordham, CUNY and George Mason University presented research related to software markets, IT strategy, security, and sustainability. The workshop successfully brought together academics and business/IT managers from the NY area to discuss current business challenges and applications of system dynamics.

Third European System Dynamics Workshop at the University of St. Gallen: The European System Dynamics Workshops are a series of biennial events, which are aimed at bringing together leading system dynamicists from European countries and contributing to the work on the important issues, in the International System Dynamics Community. The third workshop was held at the University of St. Gallen, Switzerland, from March 22nd – 24th, 2007. Among the participants were: Bent Bakken, Carmine Bianchi, Enzo Bivona, Gianluca Colombo, Brian Dangerfield, Andreas Größler, Matej Janovjak, Christian Kapmann, Florian Kapmeier, Birgit Kopainsky, David Lane, Erik Larsen, Marcel Loher, Peter Milling, Erling Moxnes, Günther Ossimitz, José Pérez Ríos, Etiënne Rouwette, Jürgen Strohhecker, Silvia Ulli-Beer, Jac Vennix, as well as doctoral students. The workshop was organized by Geraldine Frei, Stefan Grösser, and Markus Schwaninger. The contributions to the workshop are now being processed and planned to result in a special issue of the journal Systems Research and Behavioral Science.

New PhD: David Wheat successfully defended his PhD dissertation "The Feedback Method: A System Dynamics Approach to Teaching Macroeconomics." It was approved by University of Bergen, 2007. A hearty congratulations to David!

Operational Research Society Conference, Edinburgh, UK: September 2007

The 49th annual Operational Research Society conference is to be held in the beautiful and historic city of Edinburgh in Scotland on 4th-6th September 2007.

The conference will include a system dynamics stream. This will build on an interesting and successful series of system dynamics streams that have been held during the last few annual conferences. To mark the 50th anniversary of system dynamics the 2007 stream will reflect the diverse range of applications that system dynamics has been applied to since its beginnings. For example, presentations will cover the impact of system dynamics when informing policy making in healthcare, construction, supply chains, fisheries and transportation. Presenters on the stream include John Morecroft, Brian Dangerfield, Kim Warren and John Swanson. An additional aim of the stream, which will be explicitly considered during one of the presentations, is to bring together the system dynamics community in the UK and to consider how the community can continue to develop in the future.

In addition to the system dynamics stream there will be a number of other parallel streams covering a wide range of operational research topics. Streams include discrete-event simulation, health care modelling, problem structuring methods, operational research and strategy, performance measurement, European operational research consultancy, defense plus many more. The conference will be held at the University of Edinburgh which is located within easy reach for the city centre. Edinburgh is an historic, cosmopolitan and cultured city with a wonderfully striking setting. Edinburgh Castle dominates the city-centre skyline and from its ramparts you can look down on medieval lanes and elegant, sweeping terraces. The conference social program allows participants to take in the beauty of Edinburgh by joining a city walking tour, a trip to Holyrood Palace and a visit to the Royal Yacht Britannia. The beautiful city location, interesting range of topics and comprehensive social program are sure to lead to an exciting and enjoyable conference.

Evans & Peck Pty. Ltd.

Evans & Peck is a management consultancy that has been providing decision modelling advice to its clients for over 20 years. We currently operate in Australia, New Zealand, China, Hong Kong, Singapore and UAE.

Evans & Peck provides consulting services in simulation modelling (system dynamics, discrete event and agent based), simulation optimisation, financial modelling and executive dashboards.

Our modelling website ( ) provides information and examples of our entire modelling capability.

We are also the distributors of iThink, STELLA and AnyLogic software in Australia and New Zealand. We run public and private training workshops in these modelling tools at any of our international offices or at client’s premises. Contact [email protected] for details of upcoming workshops.

Over the past year we have strengthened our modelling expertise in health, transport and port logistics, human resource management and business processes. We have undertaken a diverse range of modelling assignments including:
· E-Health system benefits realisation study
· Bus fleet management
· Workforce planning for a major mining company
· Commercial frameworks for project alliances and facility asset management
· Shopping mall usage

At Evans & Peck, we continuously upgrade our modelling capabilities to respond to the needs of our clients. This year we are in development of a tool for the optimisation of project portfolio allocation. This tool combines the techniques of simulation and optimisation to aid major government agencies and private corporations select an optimal portfolio of projects. We are now seeking suitable corporations or government organisations to work with in customising the tool to their particular needs.

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

GoldSim Technology Group

GoldSim Technology Group ( began developing GoldSim, its probabilistic simulation platform, in 1990. GoldSim differs from traditional system dynamics approaches in that 1) it puts much greater emphasis on probabilistic simulation techniques to support representation of uncertain and/or stochastic systems; and 2) it provides a wide variety of specialized model objects (beyond stocks, flows and converters) in order to make models less abstract (and hence more transparent) and help represent processes and events that cannot easily be represented using a traditional system dynamics approach. This includes specialized modules to support Risk and Reliability Analysis, Financial Modeling, and Mass Transport Modeling, as well as features to simultaneously represent continuous and discrete dynamics.

These differences are due to the fact that GoldSim has most commonly been used for engineering and scientific applications where quantitative probabilistic predictions of future performance have been required (e.g., by regulators and other stakeholders) in order to inform and defend policy and design designs.

Almost 200 commercial and government organizations in 30 countries, and over 200 academic institutions use GoldSim (free, fully functional academic licenses are provided for teaching purposes). Examples of GoldSim applications include the following:

The annual GoldSim User Conference will be held in San Francisco, California October 25-26, 2007. Prior to the conference, we will offer both basic and advanced training sessions. Our annual conferences provide a terrific opportunity for you to see how others are using the software, learn about new features, share experiences with other users and the GoldSim developers, and provide input for the future development of GoldSim.

Health Market Science (HMS) is a leading company in building system dynamics models for the pharmaceutical, biotechnology, and medical device industries and a proud sponsor of the 2007 System Dynamics Conference, Boston, MA. We provide our clients with a dynamic, web-based interface, built upon a fully calibrated client-specific SD model, to be used for brand planning, new product launches and forecasting. By employing HMSí SD interface, HMS MarketSimô, our clients are able to make better business decisions and understand how their forecasts are impacted by these strategic choices. Our models incorporate all of the forces present in the highly dynamic pharmaceutical market, including the impacts of competitive brands, generic products, managed care, pricing, promotion and physician perceptions of quality.

HMS is also a leading manufacturer of health care provider data. Our models leverage our unique database, but also include our clientís market research data, which brings validity and trust to the forecast results. Based upon the product market research and client workshops, market scenarios are hypothesized and the model is developed, and then calibrated against actual market data. The online interface provides our clients an environment within which different market scenarios can be created and analyzed to support their brand planning. Throughout the modeling phase, HMS interacts closely with our clients so that they are aware of the modelís underlying assumptions and suggested structure. After delivering the model, we are involved with on-site training of the brand planning team to help them use MarketSimô and to support them with further data analysis through workshops. Finally, after the brand planning is done and new market data becomes available, HMS updates the model with the new data so that it remains a valid and valuable decision making platform.

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. For further information on the InCoCo research project, click here.

The Whole Systems Partnership

The Whole Systems Partnership ( has recently completed projects for public sector clients in the UK helping them to consider the implications of new policies and to understand the complexities of their environment. In the Scottish Borders we have enabled the local health service to work through the implications of a proposed new capital spend to develop an Emergency Care Centre. The model development has enabled a wide range of new behaviours to be explored in the context of their impact on the proposed changes, therefore making explicit the key elements relating to overall affordability of the scheme.

In an English County Council WSP have developed an innovative approach to forecasting need for long term care (residential and nursing homes) in the context of local service developments. New models of care are emerging as a result. Elsewhere we have helped a Strategic Health Authority covering a population of approximately one and a half million to model and therefore cost the potential impact of new drugs for advanced forms of eye disease.

WSP is also in advanced discussions with another Strategic Health Authority to develop a modelling tool that will link service improvement to workforce requirements. This will build on national work in the UK to identify the shape of a ‘productive team’ in the delivery of healthcare and local work to identify service improvement pathways.

The company is growing steadily and building on its strategic partnership with isee systems to develop new and innovative ways of harnessing the power of SD in the UK Public Sector. A new full time member of staff will join the team in September 2007 to support and deliver on current commitments across our consultancy business and we are looking forward to building on the existing success and reputation of the company.

WSP also continue to deliver a wide range of strategy and partnership development projects for clients across the health and social care sector. In a period of growth we have sought to ensure continued high quality and high added value in our work and have recently published the ‘WSP Distinctives’ on our web-site.
