We were very pleased with our Ventity workshop at the SD conference in Delft. We had a good crowd, with interesting questions and lots of potential applications that will benefit from our new approach.

This series of videos walks you through most of the workshop content. The workshop models are in InfectionSeries.zip, and you can get a copy of Ventity here.

Part 1

This clip introduces the key Ventity concepts of entities, attributes, collections, references and actions, using a simple SIR model.

Part 2

In this segment, we extend the basic model in several directions, without having to rewrite the core entity structure, to include:

• Multiple infection strains, created dynamically
• Multiple age cohorts, with flexible granularity
• Crossover from one species to another

Part 3

Here, we set aside the continuous paradigm and model individual agents, with well-mixed contacts and heterogeneous contacts on an explicit social network:
