چکیده

Age replacement policy is concerned with finding an optional time to minimize the cost, at which time the unit is replaced even if it does not fail. So far, age replacement policy involving random age has been proposed. This paper will assume the age of the unit is an uncertain variable, and find the optimal time to replace the unit.

AGE REPLACEMENT POLICY IN UNCERTAIN ENVIRONMENT

Block replacement policy with uncertain lifetimes

Block replacement policy is a type of preventive replacement policies where the units are always replaced at failure or at a scheduled time periodically. Assuming the lifetimes of the units are uncertain variables, this paper studies the block replacement policy in an uncertain environment. To deal with the different constraints a decision maker may face, three different criterions are used to ...

Optimal overhaul–replacement policy for a multi-degraded repairable system sold with warranty

In this research, we study an optimal overhaul–replacement policy of a multi-degraded repairable system sold with a free replacement warranty. In the proposed replacement policy, a maintenance action and failure are dependent on a system degradation level and the system age, and hence the replacement model will provide more effective maintenance decisions. Failure of the system is modeled using...

The optimal age-based replacement policy for systems subject to shocks

In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...
