基于SMP2的仿真模型测试方法研究

Study on Simulation Model Testing Based on SMP2

仿真模型的有效性评估一直是建模与仿真领域研究的重要课题。在工程大系统的仿真模型集成过程中,由于传统仿真模型的验证方法受到建模方法和建模语言的多样性以及模型重用语境变化的影响,使工程总体难以确定导致系统行为产生偏差的模型单元。从测试的角度以SMP2(仿真模型可移植性规范)为基础提出层次化语境驱动的仿真模型测试方法论,从测试框架的描述机制、测试框架的分解机制以及面向测试的仿真模型验证方法等三个方面讨论方法论的具体内容,为基于SMP2的仿真模型提出可测试性设计方法。

The effectiveness assessment of simulation models is an important task of modeling and simulation, In the process of integration of simulation models of large-scale engineering systems, because of the influence of the diversity of modeling methods and languages, and the change of the context of model reuse, it is difficult for traditional validation of models to wholly make clear the model which leads to the behavior of simulation system invalid, Accordingly, a hierarchical context driven methodology of simulation model testing based on SMP2 （Simulation Model Portability Standards） was proposed. Then the description of test framework, the decomposition of test framework and the validation method of simulation models for testing were discussed. A testability design method of simulation models based on the SMP2 was described.
