Performance Modeling and Availability Analysis of Malt Screener System in a Brewery Plant

The production process flow in a brewery comprises of various systems and subsystems arranged in series, parallel and combination of these two. The objective of the maintenance department is to achieve maximum Availability without any failure of machine components the plant. The paper discusses the Performance modeling and Availability analysis of a Malt Screener system in brewery plant by using Markov approach to find out all the probabilities of systems. The Availability model for Malt Screener system has been derived on the basis of probabilistic approach using Transition Diagram (TD).The steady state availability of the Malt Screener system has found for constant repair and failure rate as calculated from the Maintenance History sheet of brewery plant situated in Haryana and the decision Matrix developed. The critical subsystem is calculated using the sensitivity analysis. The transient behavior of variation of availability is also found for Malt Screener system using the Runge-Kutta method of fourth order and simulation is done using the MATLAB tool.
