Abstract: With the development of leasing equipment market, how to provide effective leasing maintenance service is becoming more and more important for manufacturing service providers. From the working environment perspective of leasing equipment, the shock model was used to perform fault modeling for leasing equipment. A sequential preventive maintenance strategy oriented to leasing equipment was proposed by considering failure punishment mechanism and the imperfect effect of preventive maintenance comprehensively. The optimal leasing period and maintenance plan were achieved by minimizing the expected total long-run cost per unit time. The numerical results showed that the proposed maintenance strategy was accordance with actual cases, and it could provide effective maintenance scheme for service manufacturers.
