<p style='text-indent:20px;'>The main purpose of this paper is to investigate the retailer's strategy in selecting order-up-to level, reorder point and preservation technology investment for deteriorating items, aiming maximize his total profit per unit time. We formulate problem into a mathematical model that takes account stock-dependent demand rate, holding cost. The terminal condition...

We developed an economic order quantity (EOQ) model with a learning effect and carbon emissions under inflationary conditions inspection for retailers where the items deteriorate naturally. Finally, total profit of retailer is maximized respect to cycle length. A sensitivity analysis was also performed understand robustness model. In analysis, we discuss impact rate, inflation deterioration rat...

<p style='text-indent:20px;'>In the business world, both supplier and retailer accept credit to make their position strong, because not only strengthens relationships but also increases scale of profits. In this paper, we consider an inventory model for non-instantaneous deteriorating items with price sensitive demand, time varying deterioration rate under two-level trade policy. Besides,...

 This study presents an inventory model for deteriorating items with linearly time-dependent demand rate under trade credits. Mathematical models have been derived under four different situations i.e. Case 1 : The cycle time T is greater than or equal to M1, to get a cash discount, Case 2 : The cycle time T is less than M1, Case 3 : The cycle time is greater than or equal to M2, and Case 4 : T...

Abstract— Perishable inventory constitute a large portion of the world economy and include virtually all foodstuffs, pharmaceuticals, fashion goods, electronic items, periodicals, digital goods and many more as they lose value with time due to deterioration and/or obsolescence. Retailers dealing with perishable goods have to consider the factors of short shelf life and the dependency of sales v...
