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 comple: enterprises, atype 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 thestability of resource allocation of MRO service providers.
