Economic Order Quantity Model for Delayed Deteriorating Items with Time Dependent Exponential Declining Demand by Yahaya Ahmad and Abubakar Musa (Pages 113-118)
Sale price: $5.00


In this study, an Economic Order Quantity(EOQ) Inventory model is constructed fordelayed (Non-instantaneous) deteriorating items with the assumption that the demand rate before deterioration begins is exponentially declining function of time while the demand rate when deterioration sets in becomes constant up to when the inventory is completely depleted. The deterioration rate is constant throughout the cycle, shortages are not allowed. The model is solved analytically by minimizing the total inventory cost which leads to the determination of the best cycle length. Numerical examples were provided to illustrate the application of the model developed.
