Research on Assessment Theory of Simulation Credibility

The purpose of this paper is to give an overview of simulation credibility, Verification, Validation and Accreditation (VV&A), and present a comprehensive life cycle of Credibility Assessment Scale (CAS), assessment methods, the types of interfacing system elements, and the weighting methods. The CAS help the simulation practitioners in defining the requirements, establishing conceptual model, designing the simulation system, investigating solution techniques, programming the simulation model, designing experiments, experimenting, redefining the model, and presenting the simulation results. Practitioners can follow the CAS procedure presented herein and increase the credibility in conducting a simulation study.
