Comparative Analysis of Two Single Unit Systems with Production Depending on Demand

The present paper gives the comparative analysis between two models with production depending on demand. The two models (Model 1 and Model 2) considered are on a cable manufacturing plant with the difference of scheduled maintenance. Model 1 considers a single unit system with scheduled maintenance whereas Model 2 is without scheduled maintenance. Initially, the system is in operative state and demand is greater than or equal to the production. As variation in demand affects the production of system, consequently, the system needs to be in down state when the numbers of produces are more than those demanded. This model has been compared with the model wherein the scheduled maintenance is carried out. Comparative study with respect to the availability and the profit has been made between two models. Semi-Markov processes and regenerative point technique have been used to obtain various measures of the system effectiveness for each model.

Reliability and Availability Analysis of a Single Unit System with Varying Demand

This paper investigates the reliability and availability analysis of a single unit system in an industry, depending on the variation in demand. Variation in demand affects the production also and hence the system may go to down state when the units produced are in excess. The system in the downstate is made operative as soon as the produced units are less in number than those demanded. Using regenerative point technique, Mean Time to System Failure, the Availabilities in both the cases i.e. when demand is greater than or equal to production and when demand is less than production has been obtained
