Maintenance Cost Analysis for Replacement Model with Perfect Minimal Repair
With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...
متن کاملOptimal age-replacement policy with age-dependent minimal-repair and random-leadtime
A generalized age-replacement policy with age-dependent minimal repair and random leadtime is considered. A model is developed for the average cost per unit time and is based on the stochastic behavior of the assumed system and reflects the cost of storing a spare as well as the cost of system downtime. Determination of the minimum-cost policy time is described and illustrated with a numerical ...
متن کاملAn Adaptive Bayesian Replacement Policy with Minimal Repair
In this study, an adaptive Bayesian decision model is developed to determine the optimal replacement age for the systems maintained according to a general age replacement policy. It is assumed that when a failure occurs, it is either critical with probability p or non-critical with probability 1− p, independently. A maintenance policy is considered where the non-critical failures are corrected ...
متن کاملOptimal Lot Sizing Policy for an Unreliable Manufacturing System Under Cost-Effectiveness Criterion
The traditional method of determining the optimal Economic Manufacturing Quantity (EMQ) policy for an unreliable production system is the minimization of the expected cost per unit time in the steady state which does not consider the reliability of the system in true sense. The purpose of this article is to introduce an alternative criterion of optimality called cost effectiveness which takes i...
متن کاملOptimal age-replacement time with minimal repair based on cumulative repair cost limit and random lead time
We consider an age-replacement model with minimal repair based on a cumulative repair cost limit and random lead time for replacement delivery. A cumulative repair cost limit policy uses information about a system's entire repair cost history to decide whether the system is repaired or replaced; a random lead time models delay in delivery of a replacement once it is ordered. A general cost mode...
