RELIABILITY ANALYSIS OF A WIRE DRAWING SYSTEM WITH MANDATORY REST PERIOD

The paper presents reliability analysis of a wire drawing system. Ten years maintenance data of the system depicts three types of maintenances: repair, minor preventive maintenances and major preventive maintenances. The system undergoes repair upon failure while minor and major preventive maintenances are performed as per schedule. The system operates for 16 hours, followed by 8 hours rest period. Mean time to failure, availability, expected number of repairs and expected busy period have been estimated by analyzing the system using semi Markov process and regenerative point technique.
