Abstract for: Introduction to Ventity - from Classic SD to DES, ABM and Networks

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 epidemic models, but we'll try variants with discrete events and agents, and if time permits, networks.
