逼近理想解的模糊物元方案优选分析方法

Optimization analysis of the schemes of fuzzy elements approaching an ideal solution

针对多目标问题目标体系的不可公度性和目标间的矛盾性,充分考虑到单指标评价时指标的模糊性及各指标间的不相容性,在模糊物元分析的基础上,结合优选理论中的逼近于理想解的排序法,对多目标问题的优选进行了探讨。结果表明,该方法优选结果与现场实际相吻合,且本方法矩阵化、表格化,整齐规范,利于在计算机上操作,可用于实际中多目标问题的优选决策分析。

Aimming at the impossible common measure in the goal system and contradiction among the goals in the multigoal problem and fully considering the ambiguity of index in single index＇ s evaluation and incompatibility among the indexes, this paper discusses the multigoal optimization through integrating TOPSIS and the analysis of fuzzy elements. The study proves that the result by the method is consistent with the spot fact, and the matrix and tabulate of the method is neat and normative. It can be used to the optimization decision analysis of the practical multigoal problem.
