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
This video explores the improvements possible when a complex spreadsheet model is translated into Vensim.
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 … Continue reading
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, … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
