区间数多属性决策在飞机一发失效应急程序方案优选中的应用

Application of Interval Multiple Attribute Decision-making Method to Optimal Selection of Contingency Procedure Schemes for Single-engine Failure of Aircraft

针对在飞机一发失效应急程序方案的选择中,很多定量因素难以精确量化的问题,将区间数多属性决策运用到飞机一发失效应急程序方案的优选中,构建了评价指标体系。此评价指标体系应用基于理想解的区间数多属性决策的相对隶属度法来选择最佳方案,该方法通过计算并查找现有方案的相对隶属度最大值来确定最佳方案。最后举例说明如何在实际中使用此方法。

There are many quantitative factors involved in selecting the optimal scheme of the contingency procedure schemes for aircraft＇s single-engine failure （CPSFASEF）; those factors are difficult to be precisely quantified. In this article, the optimal decision problem of CPSFASEF is studied, and an evaluation index system for optimal scheme selection is constructed by using interval number and Technique for Order Preference by Similarity to an Ideal Solution （TOPSIS）. The evaluation index system employs a method to select the optimal scheme for CPSFASEF based on the ideal solution for the interval number of multi-attribute decision-making and its relative membership degree （RMD）. The method selects the optimal scheme by finding the greatest value of RMD of available schemes. Finally, a numerical example is presented to demonstrate the computational process of the method.
