Abstract

This paper deals with stochastic analysis of a two-unit model of a paper machine with cold standby system established in a paper mill namely Sri Jagdumbe Paper Mills Ltd. located at Sirsa (Haryana) considering two types of faults i.e. minor and  major faults during operation of the machine. Minor/major faults are repairable as well as non-repairable/replaceable. It is assumed that there is facility of single repairman for repair/ replacement besides an inspection team which determines a particular fault as repairable or non-repairable/replaceable. Considering all these aspects and using the real data collected from the mill, various measures of system effectiveness such as MTSF, Reliability, Availability and Busy period etc. are derived by using Semi-Markov process and Regenerative Point technique. The results relating to profit have been derived using various graphs and numerical calculations. Further, cut-off points of profit for different values of rates of minor, major faults/ revenue of availability/costs etc. have also been obtained, which may be helpful for management team of Paper Mill to make the paper machine more profitable.
