For modeling scenarios that do not require modeling of individual agents, IDM provides Compartmental Modeling Software (CMS). CMS enables you to construct a stochastic compartmental model using a variety of different solvers. This provides a simple way for you to define the compartments and the differential equations that govern the transition from one compartment to another, while still introducing stochasticity into the simulations.
Compartmental models have the benefit of being simpler to configure and faster to run, allowing you to quickly evaluate the potential outcomes of a variety of disease transmission scenarios.
