Nowadays, companies are collaborating and forming supply chain partnerships under a certain scheme, such as a vendor-managed inventory scheme. The collaboration increases the supply chain’s visibility, which leads to cost efficiency. It may also contribute to enhancing the supply chain’s...

Das Ziel dieser Arbeit ist es Verfahren zu entwickeln, welche Lösungen zur Re-duzierung des Bestandes bei den obsoleten Artikeln mit unregelmäßigem oder keinem Bedarf anbieten werden. Hierfür erarbeitete der Autor zwei Algorithmen, welche Berechnung der Logistikkosten beinhalten. Die...

Inventory affects the production process and supply chain activities. Integrated decision inventory improves performance and optimizes supply chain activities. However, its disadvantage is the Integrated Procurement Production (IPP) inventory model, which manages the raw material inventory in...

Effective management of perishable inventory systems is often strewn with challenges, especially when a strong trade-off relationship exists between shortage and wastage of perishables: A smaller inventory increases the chance to lose sales (leading to higher expected shortage cost), while a...

We review and interpret recent work on inventories, emphasizing empirical and business cycle aspects. We begin by documenting two empirical regularities about inventories. The first is the well-known one that inventories move procyclically. The second is that inventory movements are quite...

In this paper, we examine the role of demand forecast information for price-setting newsvendors. In our model, the newsvendor faces stochastic demand that is price-sensitive, has the discretion of setting the retail price, and receives some informative signal that helps the quantity decision....

We consider a retailer that sells a perishable product, making joint pricing and inventory ordering decisions over a finite time horizon of T periods with lost sales. Exploring a real-life data set from a leading supermarket chain, we identify several distinctive challenges faced by such a...

We study inventory control involving lost sales and hence censored demand. In a long-run average framework, the demand distribution is largely unknown. As long as the stationary inventory costs are truly convex to the extent that the second lost item costs strictly more than the first lost item,...

We study a newsvendor problem with unknown demand distribution in a nonstationary demand environment over a multi-period time horizon. The demand in each period consists of a time-varying demand level and an additive random shock. Neither the demand level nor the random shock is separately...

We propose a production-cost smoothing model with Knightian uncertainty and ambiguityaversion to study the joint behavior of production, inventories, and sales. Our model canexplain four facts that previous studies find difficult to account for simultaneously: (i) the highvolatility of...

There is a growing trend towards renting rather than permanent ownership of various product categories such as designer clothes and accessories. In this paper, we study an emerging retail business model that simultaneously serves rental and sales markets. Specifically, we consider a retailer...

Using a segmented market model that includes state-dependent asset market decisions along with access to credit, we analyze the impact that transactions credit has on interest rates and prices. We find that the availability of credit substantially changes the dynamics in the model, allowing...

Problem definition: We study the optimal inventory ordering, expediting and allocation decisions in a multi-echelon supply chain over a finite horizon, in which customer orders are quoted with a fixed fulfillment time window, termed the service time target (STT).Academic/Practical Relevance:...

This paper advances significantly the literature on the optimality of the base stock policy by generalizing the demand distribution and beginning with a completely general belief prior to be updated as demands are observed over time. As the value function depends on the belief, the functional...

Safety stock is necessary for firms in order to manage the uncertainty of demand. A key component in its determination is the estimation of the variance of the forecast error over lead time. Given the multitude of demand processes that lack analytical expressions of the variance of forecast...

This paper investigates the impacts of transshipment between overconfident newsvendors who perceive the expected outcome of an uncertain event as more certain than it actually is. The conventional wisdom is that transshipment is a risk-pooling strategy for improving newsvendors’ performance....

Firms often encourage and reward existing customers for bringing in new customers. In collaboration with a (top 500) Chinese firm, we conduct one randomized field experiment and find that, although a referral reward unequivocally enhances the existing customers’ incentives to refer new...

This paper compares the cyclical and secular behavior of Japanese and U.S. inventories at the aggregate and sectoral level, 1967-1987. While, as is well known, U.S. inventories are sharply procyclical, Japanese inventories are only mildly procyclical. In neither country do inventory and sales...

Recycling of products has a great impact on contemporary sustainable business strategies. In this study, a sustainable recycling process in a production-inventory model for an imperfect production system with a fixed ratio of recyclable defective products is introduced. The piecewise constant...

In this study, joint inventory replenishment planning of an Alibaba distribution system is investigated, which contributes to the circular economy concept. The distribution system includes suppliers, central distribution centers, and front distribution centers. The total replenishment cost of...

In recent times, in the literature of inventory management there exists a notorious interest in production-inventory models focused on imperfect production processes with a deterministic time horizon. Nevertheless, it is well-known that there is a high influence and impact caused by the learning...

Inventory management is becoming very challenging for the retailer over the years due to the uncertainty in the demand and supply of products in financial risk and management systems. In a competitive market, running a business smoothly in a highly suitable place is day by day becoming tough due...

Purpose: Managing the inventory of spare parts is very difficult because of the stochastic nature of part's demand. Also, only controlling the inventory of the spare part is not enough; instead, the supply chain of the spare part needs to be managed efficiently. Moreover, every organization now...

Purpose: The objective of this research was to implement new inventory management in a footwear company through the analysis of indicators obtained from inventory data collection. Design/methodology/approach: The methods of ABC analysis, demand forecasting, safety stock, reorder point and...

The inventory carrying cost has been assumed uniform for all products in an organization or a warehouse. This assumption is not valid for a diversified range of items in an organization or warehouse. This paper tested this hypothesis of variations in inventory holding costs in a warehouse in two...

We consider a joint inventory-pricing control problem in a single-product, periodic-review, dual-supplier inventory system. The two suppliers have different lead times. One expedited supplier offers instantaneous replenishment, and one regular supplier requires an L-period lead time for...

Intermittent demand refers to the specific demand pattern with frequent periods of zero demand. It occurs in a variety of industries including industrial equipment, automotive and specialty chemicals. In some industries or some sectors of industry, even majority of products are in intermittent...
