【摘要】 对于区间数多属性决策问题,提出了两种区间数的定量化分析方法.方法一把区间数看作是一个随机区间,把属性值看作是一个随机变量,并假设它在区间上服从正态分布,方法二则验证了方法一的合理性.在充分考虑到决策者对待风险态度的前提下,对每个区间数都赋予一个评价值.最后通过求解一个线性规划模型,给出了各个方案的综合评价值,从而选出最优方案.更多还原

【Abstract】 <Abstrcat> We proposed two approaches for the quantitative analysis of intervals on multi-attribute decision-making. The first one, based on the assumption that for the attribute value there is a normal distribution in each interval, takes the attribute value as a random variable and regards the interval as a random one; the second one verifies the validity of the first one. With respect to decision-maker’s attitude to the decision-making risk, each approach assign an assessable value to each interval. From this we deduced a linear programming model, present a synthetic assessable value, and at last select the optimal alternative.更多还原
