Computational Study for Disrupted Production System with Time Dependent Demand

294-301A production system often gets disrupted due to uncertain and un-planned events like labor problem, inadequate manufacturing, machine breakdown, power supply failure etc. and manufacturer fails to deliver the product to retailers well in time. This may reduce the reliability and faith of customers on the company/product. So, manufacturer needs to study the variation of demand and customer arrival pattern before the system gets disrupted and readjust the reproduction time according to disruption. A flexible managerial decision policy for disruption based production system is required at this juncture. The paper considers the same and incorporates variable demand with the constant production rate. We have solved the disruption problem analytically to determine the production period before and after disruptions. Both increasing and decreasing trend in production run has been studied for deteriorating item. A numerical example and simulation study appended for sensitivity analysis in order to find which parameter is responsible for significant changes in disrupted production system
