针对Vague集评价过程中信息容易遗失的问题,提出采用Vague综合评价的思想进行计算.通过定义Vague基本运算法则,以及建立加权综合评价函数构建了新的评价方法.方法体现了Vague集理论描述不确定性问题的优点,反映了项目经理评价的一般特点.最后,通过案例计算,得到了公平公正的评价结果,并验证了计算结果的可靠性. Aiming at the problem that the information is easily lost in the process of Vague set evaluation, the idea of ​​Vague comprehensive evaluation is put forward, and a new evaluation method is constructed by defining Vague basic algorithm and weighted comprehensive evaluation function. The advantages of certainty problems reflect the general characteristics of project manager’s evaluation.Finally, through the case calculation, we get the fair and just evaluation results and verify the reliability of the calculation results.
