PROFIT AND RELIABILITY ANALYSIS OF MANUFACTURING PLANT OF MOSQUITO COIL IN AN INDUSTRY WITH SINGLE REPAIR FACILITY

A model of manufacturing plant of Mosquito coil in an industry is developed for its stochastic analysis by personally visiting the Jyoti Laboratory limited industry situated in Samba district of State J&K. The said system consists of three units- Mixing, Extrusion, Punching Machine. The Mixture machine is in parallel form with the other two units but Extrusion machine and Punching machine are in series form such that if any one of the two units is failed, the other is kept in standby mode. If repair of failed unit is not completed after random period of time then other units are kept in standby mode. A single repair facility is always available with the system to repair a failed unit. All the failure time distributions are taken to be negative exponential. All the repair time distributions are taken as arbitrary.
