摘要
研究了指标权重为区间数而指标属性值以确定数、区间数、三角模糊数和梯形模糊数形式给出的多属性决策问题。通过将决策矩阵准确地转化为梯形模糊数型决策矩阵,基于模糊数中心的决策原理,提出了解决此类决策问题的随机模拟方法,同时给出了具体的决策过程。实例分析表明,该决策方法具有通用性强、精度高等优点,可用于实际的舰船动力系统综合评估。
The research on the multi-attribute decision making problem with specified number,interval number,triangular fuzzy number and trapezoidal fuzzy number under incomplete weight interval information was performed.At first,the decision matrix was converted accurately to the one in the form of trapezoidal fuzzy numbers,then the random simulation solution to the multi-attribute decision making problem was obtained on the base of centroid of fuzzy number,and the detailed process of decision making was also given.The example analysis showed that the proposed decision making method was versatile and accurate,and was applicable for the practical comprehensive evaluation of warship power system.
