基于主客观赋权法的多目标多属性决策方法

Multiple objective and attribute decision making based on the subjective and objective weighting

针对多目标多属性决策方法中,传统的主观赋权法决策者主观偏好过强,而客观赋权法又过多地依赖实测数据的局限性,利用模糊数学原理,提出一种新的主客观赋权方法。主观赋权部分具有考察决策者悲观、中立、乐观3种评价态度的优点,客观赋权部分主要基于CRITIC法和熵值法,充分考虑到数据的离散性、相关性和对比强度。利用线性组合法和乘法合成归一法对新提出的主客观权重进行融合,并以通信设备的抗干扰能力评价为例进行试验分析,证明了该方法的可行性和实用性。

For main defects of traditional subjective weighing and objective weighing method in the process of multi-objective and multiple attribute decision, a new weight way combined subjective and objective weighting method was proposed. Subjective weigh method has advantages of considering three different attitudes （pessimistic, neutral, optimistic） of the policy makers. Objective weighting method was based on the CRITIC method and the Entropy value method, which fully considered the discrete, correlation and contrast intensity of the data. Finally, linear group legal and multiplication operator were used to combine subjective and objective weighting method. The feasibility and practicability of the proposed method was proved by the experiment of assessment on the anti-interference ability of the communication equipment.
