July 13, 2016
12:00 p.m. – 1:00 p.m. (EDT)
Followed by a live Q&A on Facebook
How can we respond to climate change? Can we build an economy powered by clean, renewable energy in time? Does the agreement forged at the recent Paris climate conference (COP21) deliver us from catastrophe, or is it another diplomatic disappointment? How can the science be made accessible to the policymakers, the media, and the public at large?
Join MIT Sloan Professor John Sterman on July 13 for a one-hour, complimentary webinar to experience an interactive simulation—developed by Sterman and his colleagues—that helps people understand climate change and the long-term climate impacts of policy scenarios.
This online event, The Dynamics of Climate Change—from the Political to the Personal, will explore the dynamics of the climate interactively and suggest what we can do both professionally and personally to build a safer, sustainable world. Known as C-ROADS, this award-winning modeling software has been used by more than 15,000 people, including policy makers and negotiators, in 53 nations around the world, and is freely available to participants in the webinar.
Participants of this webinar will learn:
Why discussions on climate change have led to so much public confusion
The state of climate policy after the Paris agreement
What we can do to manage the unavoidable and avoid the unmanageable
What impact you can have in your community
Who should attend:
This webinar is designed for innovators for sustainability in private, public, NGO, and hybrid sectors, as well as anyone interested in climate policy and sustainability.

Member Stephen Cucchiaro, president of 3Edge Asset Management in Boston, is featured in a story in the Bloomberg Markets magazine. The article, written by Jon Asmundsson, reveals how Stephen developed an investment method using complex systems. Stephen had studied complex systems as a math major at MIT and went on to study finance at the Wharton School at the University of Pennsylvania. It was at the Wharton School that “he began to realize that global capital markets are a perfect example of complex systems.” As a management consultant, economist, and entrepreneur, Stephen has started several investment firms, 3Edge Asset Management is the latest. He states “…part of our approach is to identify asset classes that are not only undervalued but where there’s a catalyst that we can identify.” As a result, gold and emerging markets became his current focus. The full article can be seen in the June/July issue of Bloomberg Markets.

Member Jac Vennix Gives Valedictory Lecture at Radboud University
On May 27th, Jac Vennix held his valedictory lecture Management Science: that can be quite an art at Radboud University. It served the purpose to get the System Dynamics and Group Model Building message across to a wider audience, including colleague professors and members of the University Board. Subjects discussed in the lecture included a.o.: SD: origins and basic assumptions, the Limits to Growth study (recent research shows that real developments over the last 40 years come closest to the standard scenario of LtG), SD modelling as a learning process, the need to involve stakeholders, GMB and group facilitation, the EMSD (European Master in System Dynamics) program (combining the “science of model building” with the “art of facilitation”), as well as results of evaluation studies on the effectiveness of GMB. The lecture was well received by the audience. With that lecture Jac Vennix effectively has become professor emeritus as of June 1st. On behalf of the Society, congratulations to Jac!
At the Delft Conference, the IBM Academy of Technology is hosting a hackathon to model the impact of climate changes on vulnerable populations over time. We know that climate change shut down agriculture in Syria in 2006-7 and created urban conditions of unemployment and social tension that erupted into Civil War. We want to understand the social, economic, cultural, and political ramifications of subtle and overt climate changes on societies and the way they may adapt in the future. We want to develop an international community of model developers creating re-usable model components in XMILE that can help any community in any nation to understand the long tail effects of climate change by linking SD models to Open Data resources. All models will be open source, stored online in libraries, and presented to decision-makers at an event in Washington DC in October. Please bring your computer and your ideas. XMILE-compatible modeling software will be provided for those who need it. To learn more and see the materials provided for background reading to inform the conversation, please visit the Tentative Schedule and search on “Hackathon.” Participation is open to conference attendees.

Member Carmine Bianchi is the author of the recently published book Dynamic Performance Management. In his book, Carmine provides “…useful resource to help design and implement performance management systems using System Dynamics approach.” A summary of Dynamic Performance Management states “This book explores how to design and implement planning & control (P&C) systems that can help organizations to manage their growth and restructuring processes in a sustainability perspective. The book is not designed to enable the reader to become an experienced System Dynamics modeler; rather, it aims to develop the reader’s capabilities to design and implement performance management systems by using a System Dynamics approach.” Carmine Bianchi is a Professor of Business and Public Management at the University of Palermo in Italy, and director of the Master level program in Public Management.
Member Khalid Saeed, a Professor of Economics and System Dynamics at the Worcester Polytechnic Institute, has written many articles and two books on the topic of using System Dynamics to approach economic, organizational and political subjects. Khalid’s latest publication, the Kindle edition of Development Planning and Policy Design: A System Dynamics Approach, explores the use of System Dynamics to tackle problems of poverty, environment and governance matters. In the foreword of the book, Dennis Meadows, from the University of New Hampshire, writes “In his exposition, Khalid has not proceeded to build a single complicated model subsuming all complex social and ecological relationships existing in a national organization, but has sliced the planning problem into three abstract subsystems concerning, respectively, economic growth and income distribution, management of physical resources and technology and the functioning of the political organization.”
Parallel sessions have been scheduled in the morning and afternoon on each day of the Delft conference. The Information and Knowledge Thread and the Strategy Thread are a couple of the many threads included in the schedule.
The Information and Knowledge Thread at the conference relates to the dynamics of information and knowledge including knowledge management, information systems, social network analysis, research and development, invention, and innovation. There will be three parallel presentations in the Information and Knowledge Thread. The iSIG Annual Meeting has also been scheduled in this thread.
Another thread at the conference is the Strategy Thread. There are three parallel presentations in this thread involve the development, communication and implementation of strategy, including strategic thinking, goal definition, and outcome measures for public and private organizations.

A second generation modeling service, Discovery2, designed by CHS engineers, System Dynamics Modelers, and immunologists “demonstrates and predicts the human efficacy of drug combinations and protocols aimed at curing complex diseases related to the human immune system,” according to a press release on Business Wire.
By simulating the effects of various drug combinations on diseases such as HIV and some cancers and neurological disorders, Discovery2 “helps pharma partners predict winners, but just as importantly, assists in identifying losers: those compounds which will not succeed in human trials,” the press release continues.
“The ability to foresee eventual trial results and abandon (lose early) and re-architect portions of pharma’s development pipeline should save the pharma industry decades of time and billions of dollars currently spent in failed clinical trial pipelines of complex immune system disorders,” said John Stafford, CEO at Cooper. “We believe the Cooper Discovery2 service provides a truly breakout series of value-added benefits to pharma partners, including enormous cost savings, improved pipeline confidence, accelerated time to market, longer duration revenue streams, and scientific and competitive advantage.”
Ken Cooper, Chairman of Cooper Human Systems, is a member and VP Professional Practice of the System Dynamics Society.
The Walking with the Sun project has the objective of promoting an Educative Innovation from a system thinking (ST) perspective and an indigenous worldview. The core of the project is the elaboration of a trilingual book (Odhame, Rarámuri and Spanish) about intercultural education, complementary to the formal plan of the Mexican Education Ministry. The book is composed of didactic exercises created using a ST methodology called TRIZ (Theory of inventive problem solving). This project has two overall goals: 1) making contribution for rethinking and performing school activities in a more creative way from a learning and cultural reassessment perspective and 2) becoming a tool replicable in other communities in Mexico or Latin America.
In the following days the research team will be piloting the didactic material with kids from the Tarahumara mountain range, Chihuahua, Mexico. Playing, singing and imagining are considered key pedagogic assets, by doing so kids are able to incorporate their own way of being in their daily school activities. Accordingly, this project acknowledges their laughs and jokes as part of the kids learning process, potentiating their intelligence and curiosity, but more important, allowing a cognitive channel where their environment knowledge, themselves and their community realization take a fundamental place in their education.
This project is opening a new working area for the research team, which explores the links between system thinking and indigenous worldviews for a sustainability education. Research centers, professors or similar projects references or suggestions are sought within our community to explore further collaborations.

On May 19, 2016, at the Leadership Upper Valley Heroes & Leaders event, Elizabeth Sawin gave a keynote speech about her mentor Donella Meadows. Sawin, Co-Director of the Climate Interactive, spoke about learning the process of mentoring from Donella (Dana) Meadows, who was her mentor from 1995-2001.
A blog post by Shanna Edberg on the Climate Interactive’s website features the list of the six traits of mentorship highlighted in Elizabeth Sawin’s speech. “Donella Meadows influenced so much about my life, especially where I live and the work that I do. In reflecting on how it is that she had such a significant impact, I realized that there were six habits and attitudes that she cultivated that made her a powerful influence not just on me, but on hundreds of other people.” The full post can be viewed on the Climate Interactive website.
At the System Dynamics conference this summer, we’ll be showing and teaching Vensim’s companion, Ventity.
What’s new and different about Ventity? The really big change from most simulation languages is that we’ve replaced arrays with lists of entities, identified by attributes. This makes for a more natural and data-friendly problem description. Detail becomes a property of entities, not equations, which makes it a lot easier to coordinate and change.
Entities are modular, so they’re easier to reuse and share among teams. Entities can be created and deleted dynamically, so there’s no need to simulate a lot of zeroes for things that haven’t happened yet. Similarly, a list of entity relationships can represent a sparse matrix, so there’s no need to clutter your model with zeroes for project phases that aren’t prerequisites or relationships that don’t exist among people. All this happens in a development environment with modern, interactive charts and windowing.
A consumer products firm would like to model a portfolio of products across many regional markets, distribution channels, brands and package sizes. Not all of the brands are present in each market, and package options differ for each brand. In traditional SD, it takes a lot of data work to standardize things to work with arrays. With entities, it’s easy – we create a Product entity identified by an SKU, with Market, Channel, Brand and Package attributes, and we simply don’t bother to create combinations that don’t exist. Later, when new products launch, we can add them to the model on the fly.
A health care provider would like to understand the diffusion of information about treatments through the social network of doctors. Doctors don’t know every other doctor, but they’re sparsely related through common practices, specialties and patient referrals. We can explore this as a full agent model, or a semi-aggregate model, in which information is well-mixed within organizations.
We’re already working with these models Ventity, and its entity lists are much easier to work with than arrays. We’re now testing time series data input and optimization for model calibration. We expect the next major beta release to include these capabilities, at which point we’ll be able to tackle a wide variety of industrial-strength work. This is exciting, yet we think we’re just scratching the surface of what’s possible.
That said, there are still some things that Vensim is really good at, like extreme speed, advanced algorithms and data connectivity, so we’re continuing its development in parallel. We expect it to continue to be the premiere platform for dynamics for a long time.
For more information, please see the registration request, or visit Ventana Systems UK Forum for discussions on the topic of Ventity beta. Learn more in the video demonstration “Getting Started with Ventity.”

The initiative: Systems Planning– Systems Planning stems from well-known methodological developments in various fields of knowledge, including System Dynamics and Systems Thinking, Project Management, and Strategic Planning. The initiative can be thought of as a ‘holistic conduct platform’ dedicated to ‘the art of efficiency’. Systems Planning is curated by Anastassios (Tasso) Perdicoulis with the help of a select team of scholars from various fields of knowledge.
Particularity and Links to SD/ST– Systems Planning develops and maintains its own planning methodology (SPM) and modelling language (SPML), both of which focus on three related ‘planning objects’: systems (e.g. city, state, enterprise), processes (e.g. operations, projects), and plans (or policies, or strategies) — i.e. a wider scope than System Dynamics or Systems Thinking. Systems Planning models and simulations are qualitative or ‘manual’, but include mark-up (e.g. elements of the planning problem). A common type of diagrams between SD/ ST and Systems planning are their causal diagrams: causal loop diagrams on one side, and reverse blueprints on the other, with the latter featuring semantic mark-up.
Publication and a new genre of scholarly journals– The exploration, refinement, and dissemination of ideas in Systems Planning are secured by an independent editorial venture, which defends open reviews, exceptional quality (e.g. argument, text, diagrams, typesetting), and steering clear of ‘exploitation’ or ‘underground’ publication models. The publications initiative introduces a new genre of scholarly journals designated as ‘lab journals’ that are workspaces for critical thinking, learning, and creative contribution. All publications are open to authors in the spirit, style, scope, and subject matter of Systems Planning, and also open to bona fide and well-intended contributions and feedback such as peer reviews.
The Energy Transition Game is a role-playing simulation that allows practicing social and technological transformation challenges from fossil fuels to renewable energy sources. In this micro-world where energy is essential to ensure the wellbeing of citizens, you can shape the future of the energy sector. Become an energy producer, energy provider, technology start-up, one of the government departments or civil society organizations and create new solutions for the energy system! Energy prices, cost of change, energy demand, harsh competition and consumer satisfaction – they can all affect the outcomes of your decisions.
Can you navigate through the energy transition to arrive at a better, cleaner, and more equitable future?
Each player takes a different role within a complex energy system. Each role is linked with different decisions and responsibilities leaving a space for players to create their own strategies. In an open game world, all players can freely interact with each other, make agreements, put new policies in place, and come up with creative solutions. This way the game simulates the real-life complexity of the energy transition and also creates an environment where innovations are born.
