基于综合权重多属性决策模型的装备测试性最优诊断方案获取

Achieving Optimal Diagnosis Scheme about Equipment Testability Based on Integrated Weight Multi-attribute Decision-making Model

针对诊断方案多属性决策模型中的权重确定问题,采用专家评分法和改进AHP法计算主观权重,结合客观熵值权重确定方法,给出基于数学规划模型的主客观权重综合方法,避免主观判断和客观生成权重存在的不足;实例比较结果显示该方法能够在主观和客观权值之间寻找最佳的平衡权值,能够吸取两者优点,避免不足。

In order to determining weights in multi-attribute decision-making model of diagnosis scheme, method of expert point rating and modified AHP are applied to calculating the subjective weights firstly. Then with the objective entropy weight, a way based on mathematieal programming model is given for integrating objective and subjective weights, avoiding defects of only using subjective weights or objective weights. An example shows the method can find a desirable point between objective and subjective weights, which having their advantages and avoiding their disadvantages.
