基于公理设计理论的仿真软件评价方法研究

针对仿真软件评价优选问题,提出一种基于公理设计理论的仿真软件评价方法。以公理设计理论为指导建立仿真软件评价模型,通过信息公理以信息量大小为测度来度量仿真软件产品的优劣。考虑到备选方案评价指标信息具有不完全性和模糊性特征,采用信息公理中的经典信息量计算方法存在局限性,对信息公理中的信息量计算方法进行拓展,提出基于单值点、区间数相离度、满意度和模糊信息的信息量计算方法。结合经典的和拓展的信息量计算方法,给出仿真软件评价流程。以某生产制造企业选择仿真软件产品为例,说明所提出方法的可行性和有效性,实验结果也揭示了在仿真软件商业领域竞争中软件质量起到至关重要的作用。

Research on Simulation Software Evaluation Method Based on Axiomatic Design Theory

With respect to simulation software product evaluation and optimized selection problem,a simulation software evaluation method was proposed based on axiomatic design theory.Firstly,a simulation software evaluation model was established with axiomatic design theory.Then,the ranking of simulation software products was conducted by measuring information content based on information axiom.Considering the evaluation information of alternatives has incomplete and fuzzy characteristics,the classical information content calculation method of the information axiom has certain limitation to measure the incomplete and fuzzy information.Therefore,the information content calculation method was expanded,and the expanded methods included the single-point-value-based calculation,interval-numbers-deviation-degree-based calculation,fuzzy-information-based calculation and the information content calculation based on satisfaction degree.After that,the evaluation process of simulation software was given by the combination of the classical information content calculation method and the expanded methods.Finally,the simulation software product selection of a manufacturing company was taken as an example to illustrate the feasibility and availability of the proposed method.The result also shows that software quality is very important factor in the simulation software business competition.
