• Vensim 8.1 Release
  Vensim 8.1 is now available for download. See you at the System Dynamics Conference to talk about it! https://vimeo.com/439848216
• Coronavirus & Epidemic Modeling
  Community Coronavirus Model This video explores a simple epidemic model, parameterized for a community confronting coronavirus. https://vimeo.com/397051139 You can run the model using Vensim PLE or the Model Reader (or any higher version). Our getting started and running models videos provide a quick introduction to the software. The model: For PLE/Pro/DSS: community corona 7.mdl For the Reader (or any other): community ...
• Translating Vensim models to Ventity
  This video covers Ventity’s features for importing Vensim models.0:00 – a quick overview of the import feature and how we think about it1:37 – importing a simple model of stock management18:05 – importing a more complex, subscripted competitive market model https://vimeo.com/347792882
• Dynamic Simulation > Spreadsheets
  This video explores the improvements possible when a complex spreadsheet model is translated into Vensim. https://vimeo.com/235807321
• Vensim 7 Synthesim + Sensitivity
  https://vimeo.com/223688311 In Vensim 7, we’ve combined real-time Synthesim with sensitivity analysis, so you can see the distribution of outcomes from Monte Carlo runs interactively. This is great for giving users an appreciation of the risk associated with a decision, rather than just a best guess.
• Data Science, Connected to the Bottom Line
  https://vimeo.com/206297867/1d77447143 Vensim can be used to put big data in context, by incorporating the learnings from big data in simulations that account for organizational structure and finances. Vensim can also do data intensive simulation, with flexible I/O, advanced algorithms for calibration, optimal filtering, confidence bounds and Monte Carlo simulation.
• Modeling Discrete & Stochastic Events
  It’s generally a good idea to begin thinking about your models with continuous time and quantities, particularly for strategic applications where you care about the big picture. But there are times when it matters that quantities are discrete – you can’t ride half a horse. Here’s a quick look at modeling such situations, starting with ...
• Vensim Causal Loop Diagramming
  This video shows several ways to build causal loop diagrams in Vensim. We start simple with Vensim PLE, and then illustrate some additional features, like navigation links, that are possible in DSS. The first ten minutes should have you up & running on the basics. https://vimeo.com/179249938
• Model Analysis – World Dynamics
  This video walks through a critique of the World model that kicked off the Limits to Growth debate, starting with Forrester’s World Dynamics, followed by World3 and the Limits to Growth and many subsequent works. The purpose of this video is not to discuss the mapping of the world models to the real world, though that ...

• Causal Tracing in Vensim
  A tutorial on Causal Tracing™ – following the chain of causality through a model for insight and debugging.
• Lookups in Vensim
  A tutorial on building and using lookups (table functions) in Vensim models.
• Building a Simple Vensim Model
  A quick tutorial on building and running a new Vensim model.
