基于改进熵值法的装备维修保障能力灰色评估

Grey Evaluation of Equipment Maintenance Support Capability Based on Improved Entropy Method

装备维修保障能力评估的准确度直接影响到装备的保障效能。在评估中,指标权重的确定尤为重要。针对熵值法赋权中单一指标权重过大,影响评估结果的问题,借鉴AHP赋权法,构建基于指标信息熵的判断矩阵来求解权重,克服了熵值法单一指标权重可能过大的问题。最后采用灰色系统理论对装备的维修保障能力进行了评估,通过分析评估结果,验证了该方法的正确性。

The accuracy of equipment maintenance support capability assessment directly affects the efficiency of equipment support. In the evaluation, the determination of index weights is particularly important. According to the weight of a single index method of entropy weighting in large impact assessment results of the problem. Using AHP weighting method, the judgment matrix is constructed based on the index information entropy to solving weights and overcome the entropy method for single index weight may be too large. Finally, the maintenance support capabihty of the equipment is evaluated by the grey system theory, and the correctness of the method is verified by analyzing and evaluating the results.
