Optimal 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 کاملMaintenance 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 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 کاملExtended Geometric Processes: Semiparametric Estimation and Application to ReliabilityImperfect repair, Markov renewal equation, replacement policy
Lam (2007) introduces a generalization of renewal processes named Geometric processes, where inter-arrival times are independent and identically distributed up to a multiplicative scale parameter, in a geometric fashion. We here envision a more general scaling, not necessar- ily geometric. The corresponding counting process is named Extended Geometric Process (EGP). Semiparametric estimates are...
متن کاملAGE REPLACEMENT POLICY IN UNCERTAIN ENVIRONMENT
Age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. So far, age replacement policy involving random agehas been proposed. This paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.
