舰用柴油机测试性指标分配方法研究

Research on Testability Index Distribution of Marine Diesel Engine

针对传统层次分析法存在的评分语言的不确定性、判断矩阵一致性验证困难和测试性分配差距大等问题,文中提出一种改进的模糊层次分析法对舰用柴油机测试性指标进行分配;采用三角模糊数互补矩阵对专家评分中存在的不确定语言形式进行量化处理,应用改进层次分析法建立一致性判断矩阵,最后采用迭代分配法对舰用柴油机的测试性指标进行分配;该方法稳定、合理、准确,不需要人为进行调整验证,为下一步的测试性建模设计分析奠定了基础。

Due to the uncertainty of language, difficulty in judgment matrix consistency verification and distribution gap of testability in- dex in traditional analytic hierarchy process （AHP）, a modified fuzzy AHP is proposed. Firstly, triangular fuzzy matrix is used to deal with the fuzzy language of experts; then, consistent judgment matrix is established with modified AHP method; finally, iteration distribution method is applied to marine diesel engine＇s testability index distribution. The method is stable, reasonable, accurate, does not require artifi- cial adjustment, and it provides a basis for design and analysis of testability modeling.
