This information is part of the Business Simulation Library (BSL). Please support this work and ▶ donate.

The BUSINESS SIMULATION LIBRARY (BSL) supports modeling and simulation of dynamical systems in the social sciences and ecology. Following John Sterman [3], the term "Business Simulation" is used in a broad sense, as modeling in these domains is concerned with control, decision making, and management of resources.

The BSL adopts the widely recognized System Dynamics approach and modeling paradigm introduced by Jay W. Forrester [1], [2]. System dynamics provides a versatile, foundational modeling framework, ideally suited for modeling, simulating, and analyzing strategic business or public policy issues.

Unlike existing approaches, the BSL utilizes Modelica's acausal connectors to accurately model the flow of conserved quantities such as matter, energy, or information, as well as to represent instantaneous information signal flows through causal connections. Using pre-built components and hierarchical modeling, even complex models can be developed in a fast and reliable manner with the added benefits of embedded documentation and compact presentation. A comprehensive introduction to the BSL and cyber-physical modeling is available in a recent paper [28] by the principal author.
