系统仿真可信度评估方法研究

Research on Method of Credibility Evaluation of System Simulation

借鉴国外仿真模型校核与验证(Verfication&Validation,V&V)标准和规范,提出了一种系统仿真模型可信度评估通用流程和方法。对模型评估的相关概念进行了阐述,给出了系统仿真可信度评估流程中的主要操作步骤。在评估方法中引入了考虑不确定性的特征选择验证方法进行模型验证。为展示评估验证方法的可行性与有效性,介绍了一个管路水击压力波动仿真模型可信度评估的实例。

Based on the simulation model verification and validation standards and guidelines from overseas,this paper proposed a general process and method for system simulation model credibility evaluation.This paper describes the corresponding concepts and lists the main steps in model evaluation.This proposed evaluation method employs the feature selective validation with uncertainty.In order to illustrate the feasibility and validity of the proposed evaluation method,the paper introduces an example of pressure fluctuation simulation model credibility evaluation in waterpipe.
