| Tiivistelmä: | An order-level inventory model concerning a single item is suggested for deteriorating items with a variable rate of deterioration. In the proposed model, the rate of production is uniform, shortages are allowed, set-up cost is considered, the demand rate is varying, being dependent on instantaneous inventory level, and excess demand is backlogged. The total cost per unit time is calculated, and the model is illustrated with some numerical examples. The model is applicable to problems where a low stock level adversely affects the demand rate. The rate of deterioration is assumed first to be a constant and then to be an increasing function of time. |
