Benelux Chapter Conference, 29 January 2015​ in The Hague

The Benelux Chapter announces the conference on System Dynamics Cooperation in Practice with Policy Makers and Social Scientists. The conference is organized by the Benelux Chapter together with PBL and TNO. It will be held in The Hague on 29 January 2015. You are invited to send in abstracts for papers of your System Dynamics related work, proposals for workshops or sessions and proposals for parallel streams. The conference is particularly interested in successful examples of applied System Dynamics research. The theme of the conference is based on the growth of the System Dynamics field in Benelux. Hundreds of students with some degree of System Dynamics knowledge graduate annually from one of the universities. The conference organizers write “But, if we look at policy making, governance and social science, only a small group of SD practitioners are able to integrate these worlds. What are the main reasons for SD not being used to the fullest in other areas? Are problems in social science and policy too complex to model with SD? Or are SD models too complex for policy makers and social scientist to understand? Does a gap exist between what SD has to offer and other areas of research and policy makers demand? And how can we cope with the uncertainty existing in (global) politics? During this conference, we would like to invite everyone interested or active in System Dynamics or related fields – including policy makers and social scientists – to show, discuss and elaborate on how we can aid policy makers and social scientist in their occupation.” To learn more about submission details, due dates, registration, and contact information, please visit the Benelux LinkedIn page or contact Tom Logtens at

System Dynamics Society Members David Lane and Elke Husemann awarded OR Society President’s Medal for 2014

Eileen Munro, David Lane, and Elke Husemann

The winner of the OR Society President’s Medal for 2014, for the submission judged to be best practical, implemented, application of O.R., goes to David Lane (Henley Business School), Eileen Munro (LSE) and Elke Husemann, for “Using Systems Thinking to Undertake a Review of Child Protection in England.” The work formed a central part of ‘the Munro Review’ (Munro, 2010, 2011a, b), a high-profile review of state-managed child protection activities in England, conducted for the Department for Education.

Child protection in England encompasses a wide range of services which aim to secure the safety and welfare of children and young people. This includes, for example, the provision of foster care and adoption services, and support for families. The child protection system is also responsible for the investigation of possible cases of child maltreatment, and intervention in such cases.

Drawing on the field of system dynamics, causal loop diagramming was used to map the sector. Among the evidence used in support of the map were published research, expert interviews, and comments from relevant professions (e.g. health, social work, judiciary). This systems mapping unearthed a prescriptive approach to child protection that contributed to a culture of compliance.

A second phase of work used group model building to examine the functioning of the sector. A group of professionals and experts worked over a number of sessions and created a large and complex systems map of current operations. By considering the causal mechanisms that were in operation, it became apparent that the sector was in the grip of a set of reinforcing effects, or ‘vicious circles’. The map was subsequently used to give structure to the issues the review had to address and ultimately provided an organising framework for the recommendations that were made. Of the 15 recommendations in the report, ten were accepted in full and five were accepted in principle.

Using systems thinking and causal loop diagrams the work addressed a vital area of public policy and it had a major influence on the recommendations of the Munro Review. That influence continues through on-going changes in government policy for child protection. The work was therefore judged a worthy winner of the President’s Medal for 2014.

India Chapter presents first of one-day seminar series

The System Dynamics Society India Chapter organized the first of a series of one-day seminars on Business Systems Modeling at one of India’s leading universities, the O.P Jindal Business School (JBS) in New Delhi, India. The seminar was conducted by Society members Karan Khosla (EarthSafe Enterprises) with support from Dr. Saroj Koul (Dean of Supply Chain and Logistics at JBS); it was attended by experienced mid-career professionals from across India, studying at various management programmes at the Jindal Business School. The programme’s focus was on building management flight simulators for strategic business planning. Two models were built and analysed: the first model demonstrated how delays in human resource supply chains impact project profitability; the second demonstrated how common marketing strategies for durable products can be captured and explored using a simple diffusion model. The seminars to follow in early 2015 will focus on creating SD based management flight simulators to capture processes related to production, marketing, and accounting.

News from the Brazilian Chapter: Symposium in São Paulo

The Brazilian Chapter of the Society is promoting a symposium in São Paulo, on December 4, 2014. The event will be held at FEI University Center and will include seven presentations describing applied research and consulting efforts. Guest speakers chiming in via the Web are Kim Warren, Andy Ford and Khalid Saeed. Local presenters: Edmilson Moraes will introduce the method, while Newton Bueno and João Arantes will provide examples of applications initiated in academia, and Rudolf Flunger will describe a consulting project, all of which carried out in Brazil. A closing panel will brainstorm, and address questions from the audience, discussing ways to improve formal training and to grow the client base for using the method and existing applications.

Web-Sim Fishbanks at the Federal University of the State of São Paulo

110 professionals, educators, and students from more than 30 organizations participated in the Web-Sim Fishbanks simulation lab held at the Federal University of the State of São Paulo, on September 12, 2014. The event was organized by João Arantes, of UNIFESP, and facilitated by Jason Jay, of MIT’s Sloan School of Management. It included representatives from Brazil’s Ministry of Environment, State of São Paulo Department of Education, consulting companies, and professors and students from some of the most prestigious universities in Brazil, as well as educators from two local high-schools. The Brazilian Chapter, under the leadership of Marciano Morozowski, promoted the event in partnership with MIT’s Learning Edge.

This link contains more information, photos, and videos, including links to the materials distributed, a follow-up news article published in the Brazilian media, and a bilingual report of the effort involved in putting together this large session successfully.

This simulation lab, and an upcoming SD symposium, on December 4, 2014 (to be hosted by Edmilson Moraes at FEI University Center), are evidence of the growing interest in the method and its applications, following on the footsteps of a first symposium, held in 2004, and two regional conferences, in 2006 and 2011. (We have Pierre Ehrilich, Niraldo Nascimento and Ricardo Chaim, respectively, to thank for these earlier efforts.)

Member Didier Cumenal appointed Head of Dynamic Systems Group at AFSCET

AFSCET (French Association of Systems Science Cognitive and Technical Cybernetics) represents the French community systemic to the European Union of Systems (UES). It was founded in 1999 by Lucien Mehl, State Councilor, who died in 2005. Today, it is chaired by François Dubois, Full Professor (Applied Mathematics) at the “Conservatoire National des Arts et Métiers in Paris” and member of the Laboratory of Structural Mechanics and Systems. AFSCET’s mission is to be a place where exchanges may take place with practices and lessons from diverse backgrounds. These exchanges are based on the systemic–the thought process from Information Theory and Cybernetics. Transdisciplinarity, the integration of major societal debates and thinking about the prospective are at the heart of the concerns of AFSCET. The Association invites all members who wish to participate in these discussions and thoughts. Three working groups are currently active:

  • AFSCET Café
  • Modeling of Complex Systems
  • System Dynamics (Think Tank)

“System Dynamics (Think Tank)” group is facilitated by Dr. Didier CUMENAL (Paris Sorbonne Ph.D., former Dean of the Faculty). He regularly publishes research on System Dynamics and is a long-time member of the System Dynamics Society. The primary mission of the group “System Dynamics Thinking” of AFSCET is to reactivate the dynamics systems in France. To this end, we will conduct several actions:

  • Learning the system dynamics (method, tools) to expand the vision of our economic and social environment.
  • Share with managers and academics, experience in system dynamics models.

The Association organizes conferences, workshops, discussions, seminars, devoted to the exploration of theories and systemic practices. It broadcasts all of its work with researchers, professionals and students, by means of the Internet and / or paper publications.

Climate Interactive analysis of the new US-China climate agreement

The United States and China just announced a new climate deal. China President Xi Jinping made the commitment that China would stop its emissions from growing by 2030, and President Obama announced that the United States would emit 26 percent to 28 percent less carbon in 2025 than it did in 2005. The Climate Interactive team analyzed the impact of the new climate agreement between the US and China: Breaking Analysis US China Climate Deal.

It has been picked up so far by the Associated Press and Climate Progress.

One of the advantages of the C-ROADS model is that it runs essentially instantly, so the minute news of the agreement broke, the CI team could begin to analyze the likely impacts on climate change and get the results out to the world in less than 24 hours.

For more on Climate Interactive, including access to the C-ROADS and En-ROADS models so you can try your own scenarios, see
