一种建模仿真即服务的可信度计算方法

建模仿真即服务(Modeling&Simulation as a Service,MSaaS)具有快速部署、可互操作、高安全性和应用面广等特点,而其可信度直接关系到仿真应用的成败。对此,文章提出一种MSaaS仿真可信度计算方法。根据MSaaS不同层面从数据的完备性、仿真模型精度和正确性等影响因素建立可信度指标体系;采用层次分析法(AHP)得到各级评价指标权重,通过模糊综合评价引入主因素突出型算子得到评估结果;实例验证了方法有效。

The Modeling&Simulation as a Service(MSaaS)has the characteristics of rapid deployment,interoperability,high security and wide application,and its credibility is directly related to the success or failure of simulation application.In this paper,a method of MSaaS simulation credibility evaluation is proposed.According to the different levels of MSaaS,the credibility index system is established from the influencing factors such as the completeness of data,the accuracy and correctness of simulation model,etc.;the weights of evaluation indexes at all levels are obtained by analytic hierarchy process(AHP),and the evaluation results are obtained by introducing the main factor protruding operator through Fuzzy Synthetic Evaluation,an d the effectiveness of the method is verified through examples.
