Abstract for: Intro to Ventity – mixing SD, DES and ABM in one model

Ventity is a companion to Vensim that provides an elegant way to blend classic system dynamics with discrete event and agent-based modeling. Features facilitate modularity and collaboration, provide a more natural description of detail than arrays, and solve sparse matrix problems. This is a hands-on introduction to Ventity. We will introduce the software and new concepts, including collections of entities, attributes, relationships, aggregation and allocation functions, and actions. Our testbed will be a classic SD logistics model similar to the beer game, but we'll try variants with discrete events and agents, and if time permits, networks, all in the same model.
