Whole Systems Partnership logoThe Whole Systems Partnership was pleased to receive the Steer Davies Gleave Prize for System Dynamics at the annual gathering of the UK Chapter of the SD Society in February. The prize is awarded to the best example of the use of system dynamics modelling to impact on real life challenges. The case study was based on work to model the impact of the Government's Comprehensive Spending Review on home care services in a local area in the East of England. A copy of the presentation is available on the WSP website and a podcast of the talk is available at this link.

We are also pleased to inform Society members of a significant achievement in gaining national profile and access to an SD modelling tool through its work with the National Programme for End of Life Care in the UK.  The model is deployed online and has extensive supporting material to enable end users to optimise learning and insight. WSP is now continuing to support the roll-out of this tool through regionally held master classes sponsored by the National End of Life Care Programme. As a result of its work on this programme WSP has also been successful in being selected as part of the team to develop an approach to funding palliative care services. They are working in partnership with Kings College London and the leading Public Health Observatory for End of Life Care to deliver on this work.

Recent work in the area of dementia services has also led to the launch of a network for localities using our generic modelling tool which looks at the impact on services and funding across health and social care in response to national policy objectives for improved early diagnosis and more responsive services. WSP is working with 5 locations (with two more joining soon) who have a calibrated version of the model and who are sharing service models and improving our understanding of the assumptions and relationships within the modelling tool.

Finally, we are about to run two training events—one in the North of England on the 17th and 18th May and one in partnership with Brunel University (only 5 miles from Heathrow) on the 23rd and 24th May. Details of the 17th and 18th training course are available at The second course has the same content and places are still available for booking.

Dynamic Ranges adds flexibility

With the latest Feature Pack release of Studio 8 Enterprise, Feature Pack 3, you have the possibility to work with Dynamic Ranges for array variables.

How often have you defined the dimension of your model only to find that a new market segment is emerging or several new types of products must be added to your model, which imply some rework in your model, depending on the complexity of your model?

Or have you developed a great business case that you reuse on a regular basis, but where the different clients require different dimensions for the model's array variables? Now, with Dynamic Ranges, you can change the number of elements in an array at a later stage without the need for model adaptations.

Dynamic ranges can be edited through a Presentation in a Powersim Studio 8 tool by the end-user. With a set of Action Buttons, the user may add new elements to a Dynamic Range and all associated input variables will have a default value assigned to it. The end user may change these default values to create new and updated analysis. This method is well suited for arrays that have a few elements.

As an alternative, the Dynamic Range can be defined with an Excel Spreadsheet. The Dynamic Range is set up to read the elements from the spreadsheet, which is a well suited method to import hundreds or more input data into array variables. With Dynamic Ranges the end user may update or add to the input list more elements for each dynamic range, and give corresponding input values that will be loaded into the simulation model and updated already from the next simulation.

Dynamic Ranges will add flexibility to your model project by reducing time for redesign of the model whenever requirements changes and ease the transition of using a model in another subsidiary. Also, and most important is that it will keep the simulation model alive and updated due to the fact that end-users themselves can keep the model updated in regards to the latest business conditions.

Take a look at our demonstration video of a production company on the Powersim web pages!

Powersim Software is a Norwegian company, based in Bergen. The company is the developer of all Powersim Studio 8 simulation tools. The software is based on stock-and-flow diagrams and allows for both continuous and discrete modeling.

Northwater Capital Management Inc. (Toronto and Chicago) has shifted direction dramatically over the last two years. It has sold off its fund of funds business and is currently focused on investing $500 million from its Intellectual Property Fund. The Fund is making investments where there are rich patents, copyrights, trademarks or trade secrets that can provide a legal monopoly to the investee company.  Some of the investments are in theatrical properties, some in patent management and litigation and some in small early stage companies that have break-through technologies. In the latter category the firm has made investments in energy storage and in computer vision technologies.  Northwater welcomes contact from those looking for funding in any of these areas. Northwater is particularly interested in investments that have positive feed-back loops that look like the "success to the successful" archetype.

Millennium Institute (MI) is nonprofit development research and service organization established over 25 years ago. MI provides consulting services on development issues to governments, national planning institutions, international organizations and multinational companies. MI's expertise in system dynamics modeling complements the vast field experience in macro analysis of economic, social, and environmental issues. We work with clients to develop dynamic macroeconomic models that support comprehensive and integrated scenario analysis of global, regional, and national development challenges such as poverty reduction, economic growth, climate change and global warming, and peace-building in post conflict regions. MI remains the primary pioneer in the use of system dynamics modeling and integrated analysis for long-term national planning for sustainability.

  • Our flagship model, the Threshold 21 (T21) model has been applied in over 20 countries in Africa, Asia, America, Caribbean, and Europe; including building local capacity in the countries to use the models. These countries have benefited from a better understanding of the long-term implications of policies, the feasibility of critical assumptions about economic growth and poverty alleviation, and better understanding of the cross-sector impact of policies. Many have used their customized models for producing poverty reduction strategies, developing policy and programs to meet the Millennium Development Goals, and measuring the impact of these policies and programs.
  • MI is currently undertaking several projects, among them, a collaboration with the ECOWAS Commission to strengthen its capacity to conduct research and analysis of development policy options and guide formulation of coherent regional integration and national sustainable economic growth and development programs. Collaborations are also ongoing with the Governments of Kenya and Namibia to use system dynamics to inform developing of national climate change adaptation and mitigation policies. We recently concluded a collaboration with UNEP on their Green Economy Report, which utilized the analysis provided by a customized T21 model to demonstrate that greening the economy across specific sectors can drive economic recovery and growth and lead to future prosperity and job creation, while at the same time addressing social inequalities and environmental challenges.
  • We invite you to visit our website at to learn more about or work and download some of our models.

The Signature Research Program for Health Services and Systems Research (HSSR) at Duke-NUS Graduate Medical School Singapore is delighted to be a first-time sponsor of the 2011 International System Dynamics Conference hosted by the System Dynamics Society.

HSSR is established as a center of academic excellence for research and education on the organization, funding, and delivery of health services. Our focus is on public health and clinical service innovation in an increasingly complex and connected world.  HSSR employs a systems perspective to addressing critical health issues. Systems thinking cuts across all of our research priorities and recognizes the multiple leverage points and feedback loops involved. This includes health, social, economic, political, biological and other systems.

The aim of our Program is to bridge theory and practice in a way that advances the state of scientific theory and is sufficiently pragmatic to actually improve health care practices. Our strategy for achieving this aim is to establish 'flagship' projects that are of practical importance for Singapore, engage multiple health services research participants, involve a 'systems' perspective and provide insights applicable to other countries.

Our first flagship activity is Dr. David Matchar's project 'Establishing a practical and theoretical foundation for comprehensive and integrated community, policy and academic efforts to improve dementia care in Singapore.' This project has been funded by the National Medical Research Council through their Singapore Translational Research Investigator Award (STaR Award) scheme. The main objective of this 5-year project is to establish a laboratory in Singapore for health systems modeling, focusing on the theory and methods of system dynamics. The first application of the methodology focuses on how to manage the care and treatment of older individuals with cognitive impairment. In the longer term, our goal is to build capacity in Singapore to apply system dynamics to complex issues in health.

In 2010 we created our Health Systems Design Laboratory (HSDL), led by Dr. James Thompson. One of the first public activities of HSDL was a four-day System Dynamics Workshop in March 2011. Instructors included Bob Eberlein, Jim Hines, Jim Thompson and John Ansah. Response to the workshop was overwhelming. The morning of 29 March saw the Atrium of the Duke-NUS building abuzz with activity, laughter and some confusion. Ten tables, stretched out across the Atrium space, held eighty people participating in The Beer Game. With the first day of introductory activity and lectures behind them, participants spent a day learning how to recognize when complex situations lend themselves to the application of system dynamics methodology and helped conceptualize problems using a rigorous conceptual framework. The final two days of the workshop involved a core group of thirty-six participants who experienced fundamental system dynamics computer model building. This group of participants is primed to undertake further studies of system dynamics, and several have requested more advanced instruction in system dynamics methodology. We see this as the inception of Singapore's pivotal role in expanding the application of the methodology in the field of healthcare.

HSDL members will be present at the System Dynamics Conference 2011 to present a series of papers related to the care and treatment of cognitive impairment disorders in Singapore.

The GoldSim Technology Group provides probabilistic simulation software. Organizations worldwide use GoldSim to evaluate and compare alternative designs, plans and policies in order to minimize risks and make better decisions in an uncertain world.

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

Typical Applications

The software is widely used in the environmental and energy arenas. For example, Los Alamos National Laboratory is currently using GoldSim to perform probabilistic simulations of CO2 sequestration in geologic reservoirs. Sandia National Laboratories is using GoldSim to model the reliability and availability of solar photovoltaic systems. They recently used GoldSim to model a system operated by Tucson Electric Power to study the sensitivity of energy output as a function of photovoltaic (PV) module degradation at different rates and the effect of location (solar irradiance). GoldSim is also the premier simulation tool for building probabilistic water management models in the mining industry. As such, it is used by hundreds of consulting firms and mines worldwide.

Looking for Experienced Scientific Programmers and Modelers

We are currently looking for scientific programmers with experience in energy, water resources or risk and reliability analysis. Please see the description for this and other open positions at

In December 2010, one of our team members, Gönenç Yüçel, successfully defended his PhD thesis entitled "Analyzing Transition Dynamics–The Actor-Option Framework for Modelling Socio-Technical Systems." Gönenç continues to work in our System Dynamics lab, now as a post-doc researcher, primarily in the SD Simulation and Gaming team, but also partly in the Exploratory SD Modeling and Analysis team.

Dr. Jan Kwakkel also joined the Exploratory SD Modeling and Analysis team as a post-doc researcher. Jan developed—and continues to develop—a Python shell for Exploratory System Dynamics Modeling and Analysis. This shell can be used—together with commercially available SD software packages—to explore multi-dimensional uncertainty spaces, perform directed searches, and test deep robustness of (adaptive) policies. In addition, Iman Mohammed joined our SD Simulation and Gaming team (from Bergen University) as a PhD researcher. The Exploratory SD Modeling and Analysis team will soon be joined by another PhD researcher.

New research projects—related to demographic aging and migration, to plausible mineral and metal scarcity, and to the evolution of the Dutch housing market—were initiated jointly with TNO, HCSS, OTB and other organizations. Four temporary team members are currently developing SD models related to these topics. These models will be used to explore the ensemble of plausible futures and seek robust policies over the entire ensemble of plausible futures.

On 14 April 2011, Erik Pruyt hosted the second conference of the Benelux Chapter of the System Dynamics Society (see picture). SD scholars and practitioners, policy analysts, philosophers and ethicists, operations researchers with an interest in ethical dilemmas, complexity scientists, and policy makers gathered at Delft University of Technology for this conference on "Complexity, Uncertainty and Ethics." The conference program and video streaming of some of the presentations are available on the following web site:

Also in the first three quarters of this academic year, our SD staff contributed to system dynamics education by teaching System Dynamics to 250-300 BSc and MSc students in the introductory SD courses, 200 BSc and MSc students in the SD project courses, 22 MSc students in the advanced SD course, and supervised 14 theses in System Dynamics. Two grants were awarded to the Introductory System Dynamics course to turn it into Open Course Ware and make teaching and testing materials publicly available (for more information, contact Erik Pruyt).

Decision Advancement works with organizations to take the guesswork out of decision-making, and system dynamics is an integral part of our work.

In many organizations, decisions are based on BEG: Biases, Experiences, and Guesses. This is the default human approach, and in steady state situations it sometimes works. But in dynamic situations, where things are changing either endogenously or exogenously, the BEG approach is inadequate.

Decision Advancement has a seven step framework that provides structural, operational, and behavioral insights for our clients. Both in strategic work and in departmental work we use causal diagrams as well as model simulation to identify the key aspects of the structure of the situation. This leads to discussion of operational issues and most importantly the biases and filters that people are bringing to their decision-making. We next help them to identify the true leverage points that allow them the best value for their time and money. Everyone talks these days about having to do more with less; we use system dynamics to reveal exactly how to do that.

Led by Randy Park, who holds a Bachelor in Physics and a Master in Engineering Physics, Decision Advancement works with progressive organizations. We deliver workshops and training on systems and critical thinking, experiential learning such as the Beer Game, and facilitate identification of structural organizational issues. We also help organizations prepare for the future by facilitating scenario exploration.

Decision Advancement collaborates with specialists in a variety of fields, including strategy, risk management, planning, sales, leadership, marketing, and others. We work with corporations, nonprofit, and associations in a wide variety of fields.

Randy Park has written two books: Thinking for Results-Success Strategies, and The Prediction Trap-and how to avoid it.

One example of our work is a model that illustrates the link between member satisfaction and the success of an association such as the System Dynamics Society. Member satisfaction is obviously important to association success, but most association executives and boards miss the significance of the many feedback loops that involve member satisfaction. Satisfied members do not simply renew their membership; they also talk about the Association, raising visibility and attractiveness. Yet most associations use the number of members as their key metric, a lagging indicator, whereas member satisfaction is a leading indicator. Associations around the world have told us the model is eye-opening.

ASysT also engages in fundamental research efforts aimed at improving the effectiveness and efficiency of the interagency. ASysT's current Resilience Strategic Initiative applies a whole-of-system approach to describing factors that contribute to the infrastructural, operational, and community resilience of sociotechnical systems. Systems thinking methods and tools are a key component of ASysT's approach to articulating resilience concepts and demonstrating their application throughout the interagency. Additional research is being conducted in governance of complex systems and extended enterprises.

To further the availability and application of systems thinking tools, ASysT is developing the "Systems Thinking Toolkit"—an integrated and extensible platform of visualization tools that enables storytelling and facilitates analysis of complex systems. The Toolkit is a browser-based application that does not require software installation and is fully functional without an internet connection. The initial version of the Toolkit combines systemigrams and radial maps, allowing analysts to quickly shift between structured storytelling and relationship exploration. Additional tools will be integrated with future versions.

Haig Dynamics

The very first System Dynamics (SD) conference was organized at Earl Haig Secondary School, Toronto, Canada by a group of students of the SD club at the school, Haig Dynamics. The conference program included two keynote presentations, workshops on games and simulations, introductory speeches and club presentations.

The introduction to the conference was given by the school principal, Ms. Renata Gonsalves. Her speech welcomed all the participants, who included students, teachers, and members of the community, for attending. A special thank you and welcome to Ms. Lees Stuntz was also given. The next introductory speech was given by Ms. Sue Pfeffer; a Superintendent on the Toronto District School Board, one of the largest in Canada. She spoke about the importance of education and good education for allowing students to be the leaders of the future. The last introductory speech was given by Ms. Mari Rutka, a school trustee. In her message she referred to the importance of education and students' leadership. Ms Rutka also referred to Haig Dynamics and the conference as an opportunity to learn from students.

After the introductory speeches, the first presentation was given by Yannick Ngana, president and founder of Haig Dynamics, on the “Birth of Haig Dynamics.” The major topic addressed in this presentation was the purpose of Haig Dynamics and system dynamics as a catalyst for student ideals as well as what the mandate of the club is. The speaker also briefly explained how he got interested in system dynamics and what he had hoped to achieve in learning the discipline. This presentation was then followed by the keynote presentation given by Ms. Lees Stuntz, Executive Director of the Creative Learning Exchange. Ms. Stuntz did a presentation on System Dynamics and K-12 Education. In this presentation Ms. Stuntz talked about the application of system dynamics in different schools across the United States and had video testimonies of students expressing their growth with system dynamics. These testimonies were amazing and truly powerful as they allowed for students to easily relate to them and then see for themselves how they can benefit from SD. This was then followed by the "Infections Game." This game helped instilled the notion of exponential growth and its relevance in today's society. Overall, Ms. Stuntz's presentation was spectacular in bringing about why system dynamics should be brought to high schools and in K-12 education.

Ms. Stuntz's presentation concluded the morning half of the conference, which was theme oriented on system dynamics and K-12 education. The morning half was followed by a networking–lunch which allowed for people to talk amongst themselves and reflect on the presentations they had seen. After the lunch break workshops were then run.

The workshops were led by the Executives of Haig Dynamics and some keen members of the club. There were two simultaneous workshops which were then rotated after half an hour so that people could experience both workshops.

The workshops never repeated so that different experiences with SD could have been seen. One of the two workshops was Simulations. In this workshop, simulations were run with the participants in the attempt of understanding the given system and hence optimize the outcomes. One of the simulations was a Startup Inc. Simulation. In this simulation participants were given the model for the economy the company was found in as well as its link with the structure of a company. Simulations were then run with suggestions of courses of actions given by the participants. This was also done with a School Reform simulation where the model of a school in relation to students and their performances, and the community was given. The second workshop was System Dynamics through games. The games used at the workshop were found in the Systems Thinking Playbook, which was kindly donated by Ms. Linda Booth Sweeney. This workshop was also a major success as students were able to learn about systems thinking and system dynamics through games, which continued to give positive impressions about SD.

These workshops served well to transition from the morning theme of SD in K-12 education to the afternoon theme of SD in addressing important problems in today's society. The workshops were followed by a keynote presentation prepared by Mr. Jeff Potash, who due to unfortunate circumstances couldn't make it to the conference. His presentation was given on his behalf by Ms. Lees Stuntz. Ms. Stuntz once again did an amazing job in giving the presentation about system dynamics and its various applications in addressing important and key questions. This presentation gave students the perspective needed to address these important issues that plague today's society. The presentation was then followed by another presentation on Haig Dynamics but this time on its “Life” and continued legacy at Earl Haig Secondary School. This presentation included pictures and examples of some of the activities done during club meetings as the members looked at the problems that society has and how it can all be a system.

Finally, the conference was closed by thanking all those who attended and giving special thanks to those who helped make the conference a success and to those who donated books and materials for our school's library. As a result of holding the conference many items were accumulated for the school's library. These items include a variety of books, videos of lectures by Professor Jay Forrester, and monetary donations of over $500 all for the continuation of SD at Earl Haig Secondary School. The conference also got the interest of the Toronto District School Board and they were impressed and intrigued by the applications of SD in education. At the conclusion of the conference, many goals that had been set out had been achieved, the primary one being to expose students to SD. The conference exposed students to SD through various lenses, which were K-12 education, addressing important questions, games, and simulations. This was done because students have various interests and with the various lenses we hoped to captivate the interests of multiple students and the conference did just this. Not only did it succeed in exposing students to SD, but it also was able to provide a medium for students to further their knowledge in the domain through the materials now readily available in our school's library.

In conclusion, I would like to thank all those who helped make the event a great success. Special thanks to the Creative Learning Exchange and Ms. Lees Stuntz for not only having travelled the distance and supporting the school with her donations of books but also for her continued support to the club. Thank you also to Mr. Randy Park of Decision Advancement for having joined us and for donated materials for he library. Thanks also to all those who helped with the advertisement of the conference, including Ms. Roberta Spencer, Executive Director of the System Dynamics Society. I would also like to thank the Administrative team of Earl Haig Secondary School and Vice-principal Mr. Sukhram for not only having helped in planning the event but also for having allowed teachers to miss an entire day of school to attend the conference as they felt SD is something very important. I would also like to thank Haig Dynamics' staff advisor, Ms. Christine Scholler, and her math department for continuously supporting the club and our initiatives including the conference. Finally, I would also like to thank the teachers who brought their classes to attend the conference as they felt that it was an amazing learning experience for themselves and the students. Entire philosophy, economics, math and various other classes attended. The conference, in my opinion, was a great success as many more students, teachers, and members of the community are now aware of system dynamics.

Design, Analysis and Optimization of Supply Chains, A System Dynamics Approach

William R. Killingsworth, Executive Director, MIT Forum for Supply Chain Innovation; Business Expert Press; May 2011

Abstract: Today's supply chains are not only highly complex in terms of the number of companies involved but also dynamically complex in that their behavior and performance variations over time range from “hard to comprehend” to baffling. No wonder management is so difficult and challenging. Developing an intuitive grasp of supply chain dynamic behavior is the first step in driving performance improvement.

In this book, a system dynamics framework for analyzing complex supply chain performance is presented. The feedback nature of supply chains is demonstrated and dynamic simulation models are used to examine the counterintuitive behavior that arises from time delays, lack of information, and incorrect planning assumptions. The benefits of establishing push/pull boundaries in supply chains are shown to provide increased customer service levels with modest, if not reduced, levels of inventory. Dynamic supply chain models are used to determine product lifecycle costs and the impacts of improved reliability on lifecycle costs. A basic system dynamics model is used to show that the goal of a “lean and mean” supply chain can be dangerous in periods of economic, political, and climatic volatility, and strategies are developed for improved supply chain management and performance. Supply chain executives are faced increasingly with greater complexity, faster velocities, heightened volatility, and demands for cost reduction. This is an incendiary mix of business conditions. A dynamic perspective and system dynamics models as presented in this book can provide the tools for facing these challenging demands.

New Project: Toolkit improvement for mid– and long–term forecasting of the labor market

A project that was part of an open competition of the Ministry of the Latvian Republic concluded in April. The project, "Toolkit improvement for mid- and long-term forecasting of the labor market," resulted from a contract with the Riga Technical University. The project director and leading researcher was Society member Valerijs Skribans.

The project creates a model of forecasting of the labor market in Latvia using system dynamics methodology. The Latvian labor market's characteristic feature is high labour migration to highly developed European Union countries. The developed model will be based on research from "Influence of Labor Migration on Latvia's Labor Market," the results of which were presented in Albuquerque, New Mexico, USA in 2009 at the Society's conference.

We hope the embodiment of this project will serve as powerful stimulus of the development of system dynamics not only in Latvia, but also in all Eastern Europe.
