A DECISION-MAKING AID FOR MULTI-LAYER RADAR ABSORBENT COVERINGS

摘要

A multi-criteria optimization method for manufacture of multi-layer radar-absorbent materials intended for cladding of aircraft is presented. This entails firstly the application of an optimization method by nonlinear constraints, the generalized projected gradient; secondly, theoretical and computer-aided application of a decision-making facility employing several different criteria and fusion laws. These laws are obtained by means of two mathematical methods: the first is based on Dempster and Shafer's evidence theory; the other is derived from fuzzy set theory. Several applications of the proposed method, involving firstly triple-layer materials from the same class and secondly materials from different classes whose quantity of layers varies from 1 to 5, are presented.
