Optimum Inspection Polic][es for a Standby Unit
An inspection policy for a standby unit is considered by taking a standby electric generator as an example. The expected cost by the time of the electric power supply failure is derived by rising renewal-type equations. We discuss an optimum checking time which minimizes the expected cost. We further obtain a checking time such that the probability that a standby generator has failed at the tim...
متن کاملOptimum Replacement Policies for a Used Unit
In many situations, it may be more economical to use a used unit than to do a new one. This paper considers an age replacement policy and a periodic replacement policy with minimal repair at failure for a used unit of age x. We discuss optimum replacement policies which minimize the expected cost rates for a specified age x. Further, we obtain an upper bound of an optimum time for an age replac...
متن کاملAn Optimum Inspection Policy for a One-unit System with Preventive Maintenance
This paper deals with a one-unit system that the system's failure can be detected only by inspection. This inspection takes a non-negligible random time. Consequently the system is down during the inspection whether it is operable or not. When the system's failure is detected by i-th inspection (i = 1,2, ... , n+l), the system is repaired. When the system is operable at the time of the (n+ 1)-s...
متن کاملA Two Non-identical Unit Standby System Model with Repair, Inspection and Post-repair under Classical and Bayesian Viewpoints
In this paper some important measures of reliability characteristics of a two nonidentical unit standby system model with repair, inspection and post repair are obtained using regenerative point technique. All time random variables are assumed to be independent and follow Weibull distribution. Monte Carlo simulation study is also carried out to illustrate the results for considered system model...
متن کاملCost Analysis of a Two-Unit Cold Standby System Considering Hardware, Software Failures and Inspection with Maximum Repair Time
The present paper deals with a reliability model of a two unit cold standby system that exposed to two types of failures. In each unit there are hardware and software componentes work together and fail independently. there is a single server who visits the system immediately when required. The server inspects the unit in case of software failure and decides either to repair or replace it. The h...
