基于相对重要性和熵修正的评估权重设置方法

摘要

To solve the un-reasonability of appraisal scale system in formal decision process, appraisal scale system based on relative importance and entropy correction is proposed. This method obtains prior appraisal scale based on relative importance matrix between rules, after that perform entropy correction to modify appraisal scale system based on every evaluation process. A simulation of the method is done, and formal decision system based on the method is developed. The simulation result shows that the method reacts quickly to user preference. The problems and solutions when formal decision system is implemented are also discussed.%为解决当前正式评价过程中评估权重设置不科学的问题,提出了基于相对重要性和熵修正的评估权重设置方法.该方法基于评价准则的相对重要性矩阵求得先验评估权重,根据每位评价员的评分情况对评估权重进行熵修正.对该方法的使用效果进行了仿真实验,并在该方法基础上设计和实现了正式评价系统.仿真结果表明,该方法能灵敏地根据用户偏好进行相应调整.探讨了正式评价系统在实施过程中遇到的问题和其解决方法.
