NIH grant-funding and System Dynamics

The NPR blog posted a new article titled After The NIH Funding ‘Euphoria’ Comes The ‘Hangover’. The post reflects on a paper published at Service Science in 2012 by Richard Larson, Navid Ghaffarzadegan, and Mauricio Gomez Diaz. The original published paper developed a simple difference-equation model of new funding versus past commitments for grant funding agencies, and uncovered a balancing loop which can create periodic oscillations in National Institutes of Health new competing grants and magnify effects of change in budget on new funding.

First International Workshop on System Dynamics, Big Data and Cloud Computing

The System Dynamics Africa Chapter is organizing its inaugural Chapter Workshop to exchange novel ideas and practical experience in System dynamics, “The 1st International Workshop on System Dynamics, Big Data and Cloud Computing” will be held at the Safari Park Hotel Nairobi in Kenya on 12-13 January 2015. The theme of this workshop is “Transformation for Sustainable Development” and is therefore designed for SD members and practitioners in Africa and elsewhere in the world who are interested in emerging societal challenges and how to leverage the developments in big data and cloud computing technologies. Participants will benefit from an international perspective and meaningful insights of leading SD experts and fellow delegates from the Africa region and the rest of the world.

Member Jim Thompson to present at the Third Global Symposium on Health Systems Research

Member Jim Thompson is giving a presentation at the Third Global Symposium on Health Systems Research, co-sponsored by WHO Alliance for Health Policy and Systems Research. More than 1,700 health systems researchers from 100+ countries are participating in the conference in Cape Town, South Africa, September 30 – October 3, 2014. The theme for this Symposium is on people-centered health systems: health systems that recognize that people are their central focus and resource, and that address responsiveness at population and patient levels as a central goal. The event brings together researchers, policy and decision makers, advocates, and implementers from around the world to develop the field of health systems research.

Jim’s session presents a study of a novel medicines access program to assist the poor living in rural villages in Kenya. A System Dynamics model simulates the idealized program and concerns about its actual implementation. Presentation participants will be invited to interact with the model by trying alternative parameter values and suggesting improvements to the concept model.

The presentation includes a section on System Dynamics methodology publications and global learning resources. The slides include a list of System Dynamics courses and degree programs around the world. If you have information on currently offered degree programs and university-level courses in System Dynamics, especially in Africa and East Asia, please send new or updated information to the Society using the course survey form. This information will be used to update the Society Web site.

Jim is a founding member of the Society’s Health Policy Special Interest Group and feels this occasion is a fantastic opportunity for outreach to highlight System Dynamics as an extremely powerful tool for health policy and systems research.

In Memoriam (September 2014)

Past member Richard Stevenson sadly passed away last week after recently being diagnosed with sarcoma. Richard founded Cognitus Ltd. and did much to promote System Dynamics through teaching and consultancy throughout the 1990’s. Amongst other things, Cognitus Ltd. was a sponsor of the Society, the UK distributor for the ithink System Dynamics software, and the organizer of the annual gathering of the UK Chapter in Harrogate for its first few years. Thanks to Eric Wolstenholme for sharing this information.

Global Sustainability Fellows Program

In summer 2014, the Sustainability Laboratories, New York, for the first time, realized the Global Sustainability Fellows Program (GFSP), a trans-disciplinary study program at master level for students from all over the world. The purpose of the GFSP is to support a worldwide transformation toward a sustainable society. The aim is to prepare future leaders and managers from all sectors, including governmental bodies, companies and civil society, to master this challenge. The pilot program took place at EARTH University in Costa Rica. This small University is focused on sustainability; it even has an organic farm on its campus. Participants came from 15 countries and all five continents. Besides theory, an exploration of the tropical rainforest and visits to organic farms and factories, the program included fieldwork in Martina Bustos, a poor district of the city of Liberia. Markus Schwaninger, professor at the University of St. Gallen, Switzerland, and a long-standing member of our society, was on the faculty of the GSFP. He taught System Dynamics, the qualitative version of which provided excellent tools for the fieldwork: For example, students constructed Causal Loop Diagrams, together with citizens of Martina Bustos, in order to explore paths for the development of the district. Final evaluations show that the program was a big success.

The Oasis XMILE Technical Committee has been working on the development of a standard for storing System Dynamics models, and have recently approved a Committee Specification Draft (CSD) and submitted it for 30-day public review. The public review started September 12, 2014 and ends October 11, 2014. This document defines an open XML protocol (XMILE) for the sharing, interoperability, and reuse of System Dynamics models and simulations. This is an open invitation to comment, and OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work. Reviewers may provide comments directly from the comment-tag version of the document. Full information on the 30-day Public Review of XMILE can be found on the SDForum.

Member John Sterman and Climate Interactive featured in film “Disruption

The film Disruption features incredible and informative interviews from scientists, activists and leaders – including Climate Interactive partner John Sterman of MIT. The film has been released in advance of the People’s Climate March, the largest climate march in history, happening in the streets of New York City on September 21, 2014. Climate Interactive uses system dynamics modeling to explore the interplay between social and planetary systems and focuses on climate change research. In 2009 John Sterman was part of the group that developed the Climate Rapid Overview and Decision-support Simulator (C-ROADS). The C-ROADS simulation calculated the long-term climate impacts of proposals that were under consideration in the negotiations to produce a global climate treaty at the United Nations Climate Change Conference in 2009. Last year, the System Dynamics Applications Award was presented by the Society to John Sterman, Thomas Fiddaman, Travis Franck, Andrew Jones, Stephanie McCauley, Philip Rice, Elizabeth Sawin and Lori Siegel for their work Climate Interactive: The C-ROADS Climate Policy Model. This award is presented for the best “real world” application of system dynamics.

book coverBrian DangerfieldNew Book on Discrete-Event Simulation and System Dynamics Methods

In recent years, there has been a growing debate, particularly in the UK and Europe, over the merits of using discrete-event simulation (DES) and system dynamics (SD). There are now instances where both methodologies were employed on the same problem. The new book Discrete-Event Simulation and System Dynamics for Management Decision Making edited by Sally Brailsford, Leonid Churilov, and Brian Dangerfield (pictured left) details each method and compares each in terms of both theory and their application to various problem situations. It also provides a seamless treatment of various topics–theory, philosophy, and detailed mechanics and practical implementation–providing a systematic treatment of the methodologies of DES and SD, which previously have been treated separately.
