Design scheme evaluation based on fuzzy decision maps and grey relational analysis

A scheme evaluation method based on fuzzy decision maps and grey relational analysis is proposed to solve the problem of mutual influence of the design scheme evaluation indexes. The proposed method takes grey relational analysis as a main evaluation progress, and uses fuzzy cognitive map to represent the mutual influence of the evaluation indexes. The fuzzy decision maps are used to calculate the influence relationship among the evaluation indexes. The grey relational grades of all alternatives are calculated to determine the optimal scheme. The feasibility of the proposed method is verified by taking the design scheme evaluation of small arms for example.
