针对区间数多属性决策中的不确定性问题,提出基于区间数的不确定性分析方法,用集对分析联系数中的A表示区间数的数学期望,Bi表示区间数的不确定性,借助联系数A+Bi的加、乘运算建立区间数多属性决策模型,再利用i的不同取值进行不确定性分析.实例应用表明,方法算理清晰,算法简明,分析方便,结论可靠.
Aiming at the problem of uncertainty in multi-attribute decision making with interval number, this paper proposes an uncertainty analysis method based on interval number, uses set pair to analyze the mathematical expectation of interval number in A, and Bi expresses the uncertainty of interval number. Multiplicative multi-attribute decision-making model of interval number is established by multiplication and multiplication of the number A + Bi, and then the uncertainties are analyzed by using different values of i.Examples show that the method is clear, the algorithm is concise, the analysis is convenient and the conclusion is reliable.
