Multimethod Simulation Modeling for Business Applications
Overview with Guided Model Building Example
Simulation modeling stands apart within the range of modeling tools and technologies. Simulation models allow to experiment without having to use real-life objects. The virtual modeling world is completely risk-free. Managers, researchers, and engineers can create and test models of various system designs and answer hundreds of “what-if” questions, all by virtually experimenting in a risk-free environment.
In modern simulation modeling for business systems, there are three main approaches: system dynamics, discrete event and agent-based modeling. All three modeling approaches are quite independent. Each has its own tool set, unique features, strengths, and weaknesses. The choice of method should be based on the system under study and the purpose of the modeling.
However, most real-world cases are too complex to be modeled with one method, and it is convenient to describe different parts of a system with different modeling approaches. A combination of approaches may provide the opportunity to create an accurate and multifunctional model of the system without any workarounds.
In this paper, we will cover the different approaches and define multimethod (also called hybrid) modeling. Moving from theory to practice, we will build a multimethod simulation model example, analyze it, and find the solution to the most common issue of a novice modeler: how to choose the most appropriate modeling method or combination of methods to meet your challenge and purpose.
