Profit and Reliability Analysis of a Ceramic Tile Production System Considering Various Subsystem Failures

摘要

The present paper discusses a reliability model developed for a ceramic tile production system which consists mainly of five subsystems viz. Ball Mill, Spray Dryer, Hydraulic Press, Glaze Line and Kiln that works in series configuration. Apart from these subsystems, Silo is a subsystem to store in-process material for manufacturing tiles. The working of the system also depends on the minimum storage capacity of the Silo. If raw material stored in the Silo get consumed during the repair/replacement of the failed Ball Mill and Spray Dryer subsystems, the system fails, otherwise the system remains operational. Various measures of the system effectiveness have been obtained using Markov process and regenerative point technique. The profit incurred to the system has also been computed. The conclusions for the system in respect of its reliability, availability and profit have been drawn through graphical analysis.
