This article analyzes an inventory system for items with time-varying demand. The way by which demand occurs during the inventory cycle follows a power demand pattern. The production of items allows to add stock in the inventory during a replenishment period. The production rate is proportional...

A deterministic inventory system for items with a constant deterioration rate is studied. Demand varies in time and it is assumed that it follows a power pattern. Shortages are allowed and backlogged. The ordering cost, the holding cost, the backlogging cost, the deteriorating cost, and the...

In this paper we develop a mathematical model to study optimal replenishment policy for an economic order quantity system considering items with deterioration. Demand is time dependent and follows a power pattern. The system operates over an infinite planning horizon. Replenishment is...

This paper presents a detailed analysis of inventory systems in which the demand for inventory is deterministic, varies by time in each order cycle, and follows a power pattern. Shortages are allowed. The decision variables are the initial stock level and the scheduling period. Holding cost,...
