• AN EPQ MODEL FOR NON-INSTANTANEOUS DETERIORATING PRODUCT IN WHICH PRODUCTION COST VARIES WITH TIME

Abstract

This paper discusses an Economic Production Quantity (EPQ) model with constant production rate and demand rate. The produced item undergoes non-instantaneous deterioration and the production cost varies with time. It is assumed that a single machine produces single product over an infinite planning horizon. The optimal production cycle time is derived under the conditions for continuous review model with deterministic demand and no shortage. The numerical solutions are also obtained for three Economic Production Quantity (EPQ) models for non-instantaneous deteriorating product.
