Assessment Method for Electromagnetic Protection Solutions for Electrical Control Cabinets Using AHP-TOPSIS
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.
