针对大型复杂企业维修任务集的多服务需求点和多样化需求特征，基于服务需求视角，定义一类多服务需求点下的MRO服务资源配置问题，建立以MRO服务提供商整体服务成本为优化目标，同时考虑资源紧张度、信任度和多服务需求点不同工期要求的问题模型；针对模型中的关键参数（即服务成本和资源紧张度）的特征进行分析，并给出相应的度量方法；在此基础上，设计改进的模拟植物生长算法实现求解，算法通过启发式获得初始可行解，并进行敏感性分析。研究结果表明， MRO服务资源配置模型和算法是可行和有效的，服务成本的波动、信任度和资源紧张度的变化对于资源配置结果均有影响，模型能够有效提高维修服务成本的估算能力，同时能够保持MRO服务提供商资源配置的稳定性。

For the maintenance task set with multi-service points and diversified demands of large-scale complex enterprises , a type of MRO service resource allocation problem with multi-service points is defined from view of service demand .Then it is for-mulated with the optimal total cost for overall service of MRO service providers as the goal , with considering resource intensity , trust degree and different schedule requirements .The characteristics and measurement methods of key parameters in the model ( i.e., service cost and resource intensity ) are further analyzed .To solve the model , an improved Plant Growth Simulation Algo-rithm is developed , whose initial solutions are got through heuristics .The sensitivity analysis then is made on major parameters . Final results show the feasibility and effectiveness both for the model and the algorithm are tested ;Fluctuations of service cost , trust degree and resource intensity have impacts on resource allocation , increase service cost assessment ability and maintain the stability of resource allocation of MRO service providers .
