dc.description.abstractThis thesis studies some Economic Production Quantity (EPQ) models of deteriorating items that exhibit delay in deterioration with reliability consideration. Two modifications to existing models are presented; the first modification assumes a constant demand both before and after deterioration begins, while the second modification assumes a linearly time dependent demand after deterioration begins. The unit cost of production of an item is assumed to be directly related to the process reliability and inversely related to the demand rates. Numerical examples are given to illustrate the applications of the models.en_US
