决策时应该考虑到决策者的风险态度,决策者的风险态度对决策结果有重要的影响。现有的基于Vague集的记分函数法没有考虑到决策者的风险态度,存在不足。分析了现有的基于Vague集记分函数法在决策时存在的局限性和不足,考虑到决策者的风险态度,提出了Vague集的决策者态度函数,同时进一步提出了三种新的记分函数。通过运用这三种记分函数有效地解决了决策时存在的局限性和不足,能够提供更为合理、精确的决策排序。
Decision-making should take into account the risk attitude of decision maker, the attitude of deci- sion maker has great impact on the decision-making results. Existing score functions of vague set haven't consider the risk attitude of decision maker and all have flaws. Analysis the limitations and deficiencies of existing score functions of vague set, take into account the risk attitude of decision maker,decision makers' attitude function of vague set and three new score functions are provided. Through the use of new score functions the mistakes and limitations in decision making are solved, and also can provide more reasonable and accurate decisions.
