Constructing business simulations with service patterns

Typically, system dynamics-based simulations of business processes are constructed in an ad hoc manner, with a modeler creating low-level components and defining inter-relationships one-by-one. As the numbers of process components or variables grow, the resulting model becomes ever more difficult to manage and extend. This paper discusses the definition and use of high-level business patterns that have predefined system dynamics sub-models. These patterns enable rapid construction of arbitrarily complex system dynamics models of business processes through abstraction, reuse, and unification of sub-model elements.
