2013 ISDC User’s Group Presentation
We’re pleased to share our presentation from the Vensim User’s Group meeting at the 2013 International System Dynamics Conference in Cambridge. The highlight of most immediate interest is the imminent release of Vensim 6.4, which runs in 64 bit mode, permitting models to address much more memory. An alpha version is already running on our computers.

TUDelft Exploratory Modeling and Analysis Workbench
See: http://simulation.tbm.tudelft.nl/ema-workbench/contents.html “Exploratory Modeling and Analysis (EMA) is a research methodology that uses computational experiments to analyze complex and uncertain systems (Bankes, 1993).That is, exploratory modeling aims at offering computational decision support for decision making under deep uncertainty and Robust decision making. The EMA workbench is aimed at providing support for doing EMA on models […]
Positive Feedback, Bob Walker
Bob Walker discovered yet another use for Vensim – naming his boat. He created the graphic with the name and feedback loop and then had the sign company transfer that to the back of his new boat. The result floats above the rest.
Tracking Team Skills, Peter Addor
In order to track the ability of a team to do its work it is necessary to know both how much skill the team has built up as a team and what the experience levels of the individual team members are. By creating a matrix of team membership that includes both time with the team […]
LNG Plant Design, Scott Johnson, BP
For analytic work in support of capital investment decisions the ultimate measure of success is not always clear. Plants and distribution systems that perform as expected in terms of throughput and uptime do validate the results of technical components of the simulation. Making such comparisons in detail is, however, costly and time consuming. In addition, […]
