In this article, we study an inventory system for items that have a power demand pattern and where shortages are allowed. We suppose only fixed proportion of during the stock-out period is backordered. The decision variables cycle ratio between initial stock total quantity demanded throughout cycle. objective to maximize Return on Inventory Investment (ROII) defined as profit per unit time over...

In the past few decade researches have developed their EOQ models under constant deterioration and constant demand. However, it is not true in actual practice. In this paper, we have established inventory model with exponential time-dependent demand and timedependent time-dependent deterioration. Shortages are allowed. The demand rate and unit production cost both are considered as proportional...

Abstract. A multi-objective inventory model with demand dependent unit cost and leading time has been formulated with storage space, number of orders and production cost as constraints. In most of the real world situations the cost parameters the objective function and constraints of the decision makers are imprecise in nature. A demand dependent unit cost is assumed and solved using Karush Kuh...

In his paper a deterministic two warehouse Electronic component inventory model for deteriorating items, timedependent demand, variable holding cost and vector evaluated genetic algorithm has been developed under assumption that the Electronic component inventory cost including time-dependent demand, holding cost, vector evaluated genetic algorithm and deterioration cost in Rented Warehouse is ...
