随着广域服务型制造模式的广泛应用,承租制造企业规模连续扩大,进而带动维护外包服务的全球多区域化发展.针对出租方提供“产品+服务”中存在的多中心租赁制造服务网络的广域运维调度问题,提出系统层、网络层动态交互的多中心协同维护调度策略.在系统层综合考虑设备维护停机、累积失效损失以及系统组合选取对维护决策的影响,对同一制造租赁系统内的设备进行维护成组优化,得出总维护成本最小的成组维护方案和维护时间窗;在网络层进一步考虑服务路由优化、团队派遣选取和维护响应速度对调度决策的影响,输出最小化总调度成本所对应的各团队最优服务路线.通过算例分析,验证多中心协同维护调度策略在广域运维调度领域的可行性与有效性.

With the wide application of the service-oriented manufacturing mode, the scale of leasing manufacturing enterprises continues to expand, which leads to the global multi-regional development of maintenance outsourcing services. To address the multi-location maintenance scheduling problem of multi-center leasehold networks in the provision of “products+services”, this paper proposes a multi-center collaboration maintenance scheduling (MCMS) strategy with the dynamic interaction between the system level and the network level. At the system level, it considers the impact of the maintenance downtime, cumulative failure, and system combination selection on maintenance decisions, then optimizes the maintenance grouping of machines in the same manufacturing system. Based on the proposed optimization model, the group maintenance set and the corresponding maintenance start time can be obtained by minimizing the total maintenance cost. At the network level, it further considers the impact of service routing optimization, team dispatch selection, and maintenance response speed on scheduling decision, and then outputs the optimal service route for each team by minimizing the total scheduling cost. It also verifies the feasibility and cost-effectiveness of the MCMS strategy in the field of multi-location maintenance scheduling problems by analyzing the case study.
