超效率数据包络分析模型在装备维修保障方案评估中的应用

摘要

针对传统数据包络分析方法在方案评估中不能对多个有效决策单元进一步排序的问题，采用超效率数据包络分析对装备维修保障方案进行评估。分析构建了评估指标体系，建立了基于超效率数据包络分析的装备维修保障方案评估模型；运用MATLAB编程，得到各方案的目标函数值θ*，依据θ*值大小对装备维修保障方案的优劣进行排序，并对无效方案提出改进办法。实际应用表明了方法的有效性。%To tackle the issue that traditional data envelopment analysis cannot further sort multi-ple effective decision units in the scheme evaluation,the paper conducts evaluation on the equipment maintenance support plan with super efficiency data envelopment analysis (SE-DEA).The analysis is used to build up an evaluation indicator system and then an equipment maintenance support scheme based on super efficiency data envelopment analysis;it draws the obj ective function value of each scheme by MATLAB programming. The paper also sorts the equipment maintenance support schemes according to the advantages and disadvantages in terms of value and proposes improvement approaches for ineffective schemes.The practical applications demonstrate the effectiveness of the ap-proaches.
