Abstract:

Factor space is a necessary part of accomplishing simulation model validation. In order to clarify the misusing of factor space in model validation, based on the analysis of factor relationship, credibility calculation and model defect tracing, the relationship between partial credibility which series, parallel, iterative or combined sub-model carries and grand credibility is revealed, the elements, graphic description and building method of factor space are proposed, the method of model credibility calculation and defect tracing are explained, and a model validation case study is provided to present an application example of factor space for simulation model validation.
