1 引言 最近几年,开发者在软件分析、设计、测试等阶段积极地应用建模与仿真(M＆S,Modelingand Simulation)技术。然而,一个值得关注的问题就是仿真可信度(Credibility)问题,没有可信度的仿真是没有意义的。在建模与仿真过程中,人们开始考虑一些问题,诸如:仿真模型是否真正地代表了真实世界;仿真模型产生的输出数据是否和真实世界一样;仿真模型是否具有高可靠性等。因此,建模与仿真本身的可信度评估便成为了一个不可回避的问题。目前国内外关于建模与仿真的可信度评估主要是围绕M＆S的校核、验证与确认(Verification、Validation、andAccreditation,简称VV＆A)而进行的。
1 Introduction In recent years, developers have actively applied M & S (Modeling and Simulation) technology in the software analysis, design and testing phases. However, one issue that deserves attention is the simulation of the issue of Credibility. There is no point in simulating without credibility. In the process of modeling and simulation, people began to consider some questions, such as: whether the simulation model truly represents the real world; whether the output data generated by the simulation model is the same as the real world; whether the simulation model has high reliability or not. Therefore, the credibility of modeling and simulation itself has become an unavoidable assessment. At present, the reliability assessment of modeling and simulation at home and abroad mainly focuses on M & S verification, validation and verification (VV & A).
