摘要
针对复杂电磁环境中控制电气机箱电磁防护方案评价准则多且评价指标繁杂的特征,提出了一种AHP与TOPSIS相结合的方法.分析了机箱可能产生电磁耦合或电磁干扰的要素,提出箱体面板、机箱材料、机箱内外交互、机箱加工工艺、机箱接地与搭接5 个评价准则及与之相关的11 个评价指标.使用层次分析法(AHP)确定各评价指标的权重,通过理想点排序法(TOPSIS)构造判断矩阵,结合各指标的权重建立加权评价模型,计算评价指标的理想解、负理想解及方案中指标与理想解、负理想解的欧几里德距离,通过相对贴近系数的计算进行设计方案排序,贴近系数最大为最优方案.通过具体案例的分析,证明了方法的可行性.
Abstract
A method is proposed combing the analytic hierarchy process(AHP)and TOPSIS as an alternative to the numerous and diverse assessment criteria for electromagnetic protection solutions for electrical control cabinets in complicated electromagnetic environments.Factors that may cause electro-magnetic coupling or electromagnetic interference are analyzed,and five assessment criteria are pro-posed,which include the cabinet body panel,cabinet materials,cabinet internal and external interac-tions,cabinet processing technology,cabinet grounding and lapping.This is followed by 11 related evaluation indices.The AHP method is used to define the weight of every index,and the structure of the decision matrix is established by the TOPSIS method.The weight of every index is used to establish a weighted evaluation mode.The ideal solution and negative ideal solution are calculated together with the Euclid distance between the solutions and the indices in the proposal.The design solutions are se-quenced by calculating the relative closeness coefficient.The with the largest closeness coefficient is the best.The feasibility of the assessment method is verified through the analysis of specific cases.
