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.
