Performance Measurement Parameter Selection of PHM System for Armored Vehicles Based on Entropy Weight Ideal Point

摘要

A performance measurement parameter selection method of PHM (Prognostics and Health Management) system for armored vehicle based on entropy weight ideal point is proposed, aiming at the problem that there are too many performance measurement parameters of armor vehicle PHM system and lack of theoretical guidance to the selection of these parameters. a measurement parameter set of PHM system, according to the relationship among armored vehicle safety comprehensive plan, training use, maintenance, equipment management requirements and PHM system performance measurement parameters. Then, the armored vehicle PHM system requirements are used to working as evaluation indexes of PHM performance measurement parameters, and an objective attribute matrix is constructed, based on which the entropy weight of the evaluation index is calculated, and then the ideal points of optimal membership matrix is calculated. Then, the close degrees between evaluation parameters and ideal points are calculated, and the performance measurement parameter sequence is obtained according to the value of close degrees. The results of the example shows the order of performance measurement parameters can be obtained effectively through the index superiority matrix without expert weight, which provides basis for performance measurement parameter selection of PHM system.
