Addictive goods fundamentally differ from non-addictive goods: consuming more of an addictive good today reinforces the addiction and increases the likelihood of future consumption. Thus, addiction creates an intertemporal link between a consumer’s past and present decisions, altering their incentives to purchase and to hold inventory. Despite the influence of addiction, its impact on consumer ...

Gray markets are unauthorized channels of distribution for a supplier’s authentic products. This paper studies a distribution channel that consists of a supplier who offers all-unit quantity discounts for batch orders to enjoy cost savings, and a reseller who may divert some goods to the gray markets. Our analysis shows the impact of gray markets depends on the reseller’s batch inventory holdin...

Firms are increasingly interested in transport policies that enable a shift in cargo volumes from road (truck) transport to less expensive, more sustainable, but slower and less flexible transport modes like railway or inland waterway transport. The lack of flexibility in terms of shipment quantity and delivery frequency may cause unnecessary inventories and lost sales, which may outweigh the s...

Abstract: In today’s world the financial decisions of any business/retail enterprise are very crucial, as from the financial standpoint, an inventory i.e., stock on display represents a capital investment and must compete with other assets for a firm’s limited capital funds. Moreover, rising inflation rate directly affects the financial situation of an organization. On the contrary, the today’s...

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 ...

In this paper, we considered a deterministic inventory model with time-dependent demand and time-varying holding cost where deterioration is time proportional. The model considered here allows for shortages, and the demand is partially backlogged. The model is solved analytically by minimizing the total inventory cost. The result is illustrated with numerical example for the model. The model ca...

– All-unit order frequency discount • 94%-effective policy for a variable base period – Incremental order frequency discount • 94%-effective policy for a fixed base period • 98%-effective policy for a variable base period Introduction • A supply chain is a network of facilities that procure raw materials, transform them into intermediate goods and then final products, and deliver the products t...

Inventory control of spare parts is essential to many organizations, since excess inventory leads to high holding costs and stock outs can have a great impact on operations performance. This paper proposes a methodology for effective spare parts inventory control, motivated by a case study at a large oil refinery. Different demand modeling techniques and inventory policies are evaluated using r...
