Reliability and Profit Analysis of Some System Working Under Extreme Cold Weather Situation

The present paper deals with the study of a reliability model for a system in which operation is affected by unstable weather conditions. This model consist two units which are non-identical in nature. This situation was observed by the authors in a manufacturing company wherein the working of the system needs to be shut down when the weather conditions rises beyond a certain limit. Present model is based on this situation. The problem of stopping the working of the system does not come in the winter for the location considered for the model. However, during summer, there is possibility when the system gets stopped due to dipping down in the temperature below a certain level. Various measures of the system effectiveness like MTSF, steady state availability, busy period, expected number of visit of the repairman, expected down time have been obtained making use regenerative point technique. In this article we have computed mean time, cost analysis and system failure with the help of reliability.
