Business Simulation Library (BSL)

A Modelica library for modeling & simulation of dynamical systems in the social sciences, e.g., business, economics, and ecology using the System Dynamics metaphor.

Library Description

System Dynamics offers a very general, low-level modeling paradigm, that lends itself perfectly to model, simulate, and analyze strategic business and policy issues in any kind of organization. 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 more compact models in a fast and reliable fashion.

Overview of the Main Packages

Icon	Name	Description
	CausalLoop	Agile system dynamics modeling with quantitative causal loop diagrams (CLD+)
	Stocks	Containers ("reservoirs") used to represent entities that have been stored in a specific state
	Flows	Processes that move entities from one stock to another at a specific rate
	SourcesOrSinks	Flows into or out of a stock with infinite capacity at a system's boundary
	Converters	Information processing (blocks)
	InformationSources	External information input
	MoleculesOfStructure	Pre-built components to model information processing, decision making and subsystems in general (blocks, incubators, transceivers, and actuators)

Using the pre-built components modelers can start to build their own components to eventually arrive at an appropriate representation of the system in focus in a hierarchical fashion.

Documentation and Release Notes

Release Notes are included with the documentation and can be found there as well.

The library was developed and tested using Wolfram System Modeler and Wolfram Mathematica.
User experience may differ when using other modeling and simulation environments.
