概率为区间灰数的多目标风险型决策方法

A Risk-based Multi-objective Decision-making Method When the Probability Is Interval Gray Number

本文提出了概率为区间灰数的多目标风险型决策的概念。对于概率为区间灰数,指标值为实数的多目标风险型决策问题,根据区间灰数的运算法则,化风险型决策为无风险型决策,再利用投影算法,根据投影值的大小对备选方案进行排序和择优。最后给出一个案例,证明方法的有效性。

This paper presents a risk-based multi-objective decision-making concept which the probability is interval gray number. When the probability is interval gray number and the index value is real number, according to the interval gray number algorithms, change the risk decision-making into the risk-free decision-making, then use the projection algorithm, we can select the best one according to the projection value. Finally, give a case to prove the method is effective.
