针对服务型制造模式和维护外包服务，面向租赁生产系统的串并联复杂结构和多工序产能需求，提出以产能平衡为前提的租赁利润最大化机会维护策略.以租赁生产系统的串并联结构为研究重点，在维护决策建模中考虑整个系统的产能平衡；构建多类型设备健康演化趋势函数，规划成本率最小化的贯序预知维护计划；在工序层和系统层，以单设备预定的维护时点为组合维护契机，优化机会维护方案；建立以产能平衡为导向的租赁利润优化策略，改进租赁利润结余算法，以实时生成机会维护方案，在保证产能平衡的同时实现租赁利润最大化.通过对比租赁合同期内的全局性维护方案，验证了该策略在服务外包决策中具有显著的经济优势.
Aimed at service-oriented manufacturing model and outsourcing paradigm, an opportunistic maintenance strategy based on capacity balancing is proposed to meet the demand of complex series-parallel structure and multi-process, eventually maximizing the leasing profits. The series and parallel structures are taken as the research emphasis. And the capacity balancing of the whole system is also considered. Sequential maintenance scheduling for each machine with individual health evolution aims to minimize the maintenance cost rate. At the process layer and the system layer, these maintenance time points are taken as combined maintenance opportuuity. A capacity balancing-oriented leasing profit optimization (CB-LPO) policy is also developed by considering the capacity balancing to dynamically optimize maintenance decisions. In this study, by comparing with the global maintenance scheme during the lease contract period, it is verified that the proposed strategy has significant economic advantages in service outsourcing decision-making.
