Profit Analysis for a Stochastic Model on a Cement Grinding System with Categorisation of Failure on the Basis of Cost for Its Nine Components

Ritu Gupta, Gulshan Taneja


A stochastic model for profit analysis of a cement grinding system with failure in the nine important components namely; Belt Conveyor, Bucket Elevator, Separator, Roller Press, Diverting Gate, Process Fan, Cyclone, Ball Mill and Fly Ash System has been developed. The failure in these components has been divided into various categories on the basis of cost of repair/replacement. The fly ash system is a component in which a failure may not cause the failure of the complete system instantly. Data on time to repair and cost of repair/replacement for different types of failure have been collected from Shree Cement Ltd., Khushkhera, Rajasthan, India. The system has been analysed by using semi – Markov processes and regenerative point technique and various measures of system effectiveness have been obtained. Profit incurred to the system is obtained and graphs are plotted for the model for better interpretation of results.

Keywords: Stochastic Model, Cement Grinding System, Categorisation of Failure, Measures of System Effectiveness, Profit Analysis.
