Abstract |
|
|
| 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. |
