An Opportunistic Maintenance Policy of Multi-unit Series Production System with Consideration of Imperfect Maintenance
نویسندگان
چکیده
This paper proposes an opportunistic maintenance policy for the multi-unit series production system. This proposed maintenance policy is on the basis of the failure rate analysis, which is more realistic than age-based or time-based opportunistic replacement models. When a system halts for performing preventive maintenance or opportunistic maintenance, the alternative decision of replacement and repair is made by economic evaluation of these two types of maintenance actions. The optimal preventive maintenance plans in a finite time horizon can be obtained by adjusting the preventive maintenance threshold and opportunistic maintenance threshold. A numerical example is given for illustrating the applications of the proposed policy.

An integrated production and preventive maintenance planning model with imperfect maintenance in multi-state system
Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

This paper studies a series production system through the integration of the decisions associated with Maintenance Management (MM) and Statistical Process Control (SPC). Hence, the primary question of the paper can be stated as follows: In a series production system, how can the decisions of MM and SPC be coordinated? To this end, an integrated mathematical model of MM and SPC is developed. Usi...

This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the sy...
