Reliability Analysis of a Single Machine Subsystem of a Cable Plant with Six Maintenance Categories

摘要

The paper presents a reliability analysis of a single machine subsystem of a cable plant. Seven years maintenance data of a cable plant have been collected. Six types of maintenance practices noted for the subsystem: electrical repair, electronic repair, mechanical repair, thermal repair, minor preventive maintenances and major scheduled preventive maintenances. The subsystem is repaired on normal failures and minor preventive maintenances are performed at random whereas the major preventive maintenances are carried out on scheduled basis. Subsystem is analyzed using semi Markov process and regenerative point technique. Reliability indices of interest such as mean time to subsystem failure, availability of the subsystem, expected busy period of the repairman and expected number of subsystem repairs, are obtained. Simulated results are shown through necessary graphs.
