This information is part of the Business Simulation Library (BSL).

The BUSINESS SIMULATION LIBRARY (BSL) supports modeling & simulation in the social sciences and ecology. Following John Sterman [3] the name "Busines Simulation" was chosen in a rather broad sense since ultimately modeling in these domains is concerned with "control", "decision making", and "management".

The BSL follows the widespread System Dynamics metaphor and modeling approach introduced by Jay W. Forrester [1], [2]. System Dynamics offers a very general, low-level modeling paradigm, that lends itself perfectly to model, simulate, and analyze strategic business or public policy issues.

Unlike existing aproaches the BSL makes use of Modelica's acausal connectors to better distinguish material/mass flows from instantaneous information signal flows (causal connections). The approach has the additional benefit of allowing the modeler to build rather compact models in a fast and reliable fashion.

To get started with the library, it is recommended to have a look at:
