针对具有正态随机变量的多属性决策(MADM)问题,提出了一种决策分析方法.在该方法中,首先通过理论分析给出根据期望和方差确定正态随机变量随机占优关系的简便方法;其次依据得到的简便方法确定针对各属性的两两方案之间的随机占优关系,并构建相应的随机占优关系矩阵;在此基础上,给出了一种基于ELECTREⅢ的方案排序方法.最后,通过一个算例说明了所给方法的可行性和有效性. Aiming at the problem of multiple attribute decision making (MADM) with normal random variables, a decision analysis method is proposed, in which a simple and convenient method of determining the stochastic dominance relation of normal random variables according to expectation and variance is given first through theoretical analysis Secondly, according to the simple method, the stochastic dominance relation between each pair of schemes for each attribute is determined and a corresponding stochastic dominant relation matrix is ​​constructed. On the basis of this, a scheme ranking scheme based on ELECTREⅢ is given. Finally, an example is given to illustrate the feasibility and effectiveness of the proposed method.
