“…In a forthcoming study, it would be of interest to study the system availability under calendar based inspection policy, where inspections are scheduled according to the calendar time. 53–55 In our models, several imperfect repairs is carried out before a perfect repair, also of interest would be the availability under time based maintenance policy or condition based maintenance policy. 56–58…”

This paper studies the availability and optimal maintenance policies for systems subject to competing failure modes under continuous and periodic inspections. The repair time distribution and maintenance cost are both dependent on the failure modes. We investigate the instantaneous availability and the steady state availability of the system maintained through several imperfect repairs before a replacement is allowed. Analytical expressions for system availability under continuous and periodic inspections are derived respectively. The availability models are then utilized to obtain the optimal inspection and imperfect maintenance policy that minimizes the average long-run cost rate. A numerical example for Remote Power Feeding System is presented to demonstrate the application of the developed approach.

“…A multi-valued decision diagram based method is then developed to evaluate the proposed JIIM for general repairable systems. Zhao et al (2020)presented a joint inspection and spare ordering policy for a single-unit system with two levels of defective states, and introduced a threshold level to decide whether to place an emergency order or wait for the normal order when the normal ordered spare hasn't been delivered. Liu et al (2017) developed a maintenance policy for a multi-unit system subject to hidden failures and the inspection intervals for each component was determined by minimizing the long-run cost rate.…”

“…The papers [36−38] studied a joint maintenance and spare parts policy for complex systems with a number of identical components using the two-stage delay-time concept. Based on a three-stage failure process, the joint policy of inspection-based replacement and spare ordering has been modeled in our previous work [39,40], in which a non-repairable single-unit system is considered, thereby replacement is the only maintenance action. However, we are interested in a single-unit system that is expensive and critical in companies; in general, it could require a much longer lead time for delivery.…”

This paper presents a joint optimization policy of preventive maintenance (PM) and spare ordering for single-unit systems, which deteriorate subject to the delay-time concept with three deterioration stages. PM activities that combine a nonperiodic inspection scheme with age-replacement are implemented. When the system is detected to be in the minor defective stage by an inspection for the first time, place an order and shorten the inspection interval. If the system has deteriorated to a severe defective stage, it is either repaired imperfectly or replaced by a new spare. However, an immediate replacement is required once the system fails, the maximal number of imperfect maintenance (IPM) is satisfied or its age reaches to a pre-specified threshold. In consideration of the spare 's availability as needed, there are three types of decisions, i.e., an immediate or a delayed replacement by a regular ordered spare, an immediate replacement by an expedited ordered spare with a relative higher cost. Then, some mutually independent and exclusive renewal events at the end of a renewal cycle are discussed, and the optimization model of such a joint policy is further developed by minimizing the long-run expected cost rate to find the optimal inspection and age-replacement intervals, and the maximum number of IPM. A Monte-Carlo based integration method is also designed to solve the proposed model. Finally, a numerical example is given to illustrate the proposed joint optimization policy and the performance of the Monte-Carlo based integration method.
