Reliability Analysis of Hinges Manufacturing System considering Repairs by External Repairman and Priority given to Hardware Repair

Abstract

The purpose of this paper is to analyze the hinges manufacturing system stochastically by assuming the concept of priority. Here, two units of hinges manufacturing machine are taken in which one unit is operative and another is kept in spare. For smoothly working, an external repairman gives the service to the system. The machine functions properly to do the assigned jobs with full efficiency after repairs. The priority is given to hardware repair over other repairs. The rate of short circuit in machine, hardware and power failure rates follow the Weibull distribution. Also, the distributions of all the repair rates are taken as Weibull. The reliability measures in steady state are determined by using of semi-Markov process and regenerative point technique. The behavior of the important measures is shown graphically for arbitrary values of parameters.
