基于熵权和改进的层次分析法的总图设计方案评价

针对传统工业总图设计方案中优选方法的不足,结合总图布置自身的特点,构建总图设计方案的评价指标体系;对指标值进行归一化算子处理,使得指标有同一的比较量纲.利用改进的层次分析法和熵权法,对总图设计方案的各项指标进行组合赋权,并通过分析处理得到较为合理的设计方案排序.运用该模型进行实例分析评价,并得出评价结论.结果表明该方法模型方法简单,计算量小,在权重确定上弥补了单一方法的不足,进一步提高了结果的可靠性,具有很好的实用性.

Scheme evaluation of general layout design based on entropy weight and improved hierarchy analysis method

Aimed at the insufficiency of optimal selection scheme for conventional industrial general layout design and taking account of the feature of general layout proper,an evaluation index system for general layout design was formed.Then the magnitude of index was processed with operator normalization to make identical comparable dimension of the index.The improved hierarchy analysis method and entropy weight method were used to carry out combined weight assignment to all indices of general layout design scheme,so that a rational ordering of the design schemes would be obtained after analyzing and processing the foregoing data obtained.Finally,an actual general layout design was given to show its analysis and evaluation with forgoing method and its evaluation result.It was shown by the result that the method proposed was simple with minimum labour of computation,the insufficiency of single evaluation method was made up by the determination of weight,the reliability of evaluation was further improved,and this method exhibited very good practicability.
