模糊BCC模型及其在武器装备方案选择中的应用

摘要

In fuzzy environment,to choose the most appropriate weapon project for our army,a new class of fuzzy expected-value BCC model(short for EBCC)based on credibility theory and fuzzy expected-value model is established.Then the linear property of the expected value operator to change the proposed model into its crisp equivalent class is used.Lastly,the EBCC comprehensive evaluation model of weapon project selection is established.With the example of the radar project selection,the relative efficiency is evaluated,the decision making units of EBCC expected efficiency are sorted,and the validity and the effectiveness of this approach are tested,and the established EBCC comprehensive evaluation model provide scientific basis for weapon project selection.%在模糊环境下,为了选择最适合我军作战需求的武器装备方案,首先基于可信性理论和模糊期望值模型,建立了一类新的模糊期望值BCC(简记为EBCC)模型；然后利用期望值的线性性质,把所建立的EBCC模型转化为其等价形式；最后,利用EBCC方法构建了武器装备方案选择问题的综合评价模型,以雷达装备方案选择为例,从相对有效性评价和EBCC期望有效决策单元的排序两个方面,验证了方法的正确性和可行性,为武器装备方案选择提供科学依据.
