Abstract

The invention belongs to the technical field of system performance evaluation, and discloses a system performance comprehensive evaluation method, which comprises the steps of establishing a comprehensive evaluation hierarchical model of system performance, the comprehensive evaluation hierarchical model of system performance comprising a target layer, a criterion layer and an index layer; obtaining at least one subjective index weight vector through a subjective weighting method, and obtaining at least one objective index weight vector through an objective weighting method; performing comprehensive integration weighting on the subjective index weight vector and the objective index weight vector by adopting a genetic algorithm, and obtaining a comprehensive integration weighting vector; and improving the TOPSIS model in combination with the comprehensive integrated weighting vector, and comprehensively evaluating the system performance by using the improved TOPSIS model to obtain evaluation information. According to the method, the problem that the comprehensiveness, accuracy and objectivity of a method for comprehensively evaluating the system performance in the prior art need tobe improved is solved, and the method has good comprehensiveness, high accuracy and certain applicability.

Description

technical field [0001] The invention relates to the technical field of system performance evaluation, in particular to a system performance comprehensive evaluation method. Background technique [0002] With the continuous industrialization of electromechanical system technology, the allocation and evaluation of comprehensive performance of motorized systems has become an urgent problem for scholars and manufacturers. Taking the vehicle drive motor system as an example, as an important part of the vehicle drive, the selection, coordination and evaluation of performance indicators of the drive motor system (including the motor body and controller) have attracted the attention of new energy vehicle manufacturers. Therefore, a comprehensive, scientific and objective evaluation and decision-making method is needed to comprehensively evaluate the safety, reliability and economy of the vehicle drive motor system. [0003] The comprehensive evaluation of vehicle drive motor system...
