  摘要：We consider the transport of containers through a fleet of ships. Each ship has a capacity constraint limiting the total number of containers it can carry and each ship visits a given set of ports following a predetermined route. Each container has a release date at its origination port, and a due date at its destination port. A container has a size 1 or size 2; size 1 represents a 1 TEU (20-foot equivalent unit) and size 2 represents 2 TEUs. The delivery time of a container is defined as the ...

  摘要：We analyze a supply chain consisting of a supplier and a retailer. The supplier's unit production cost, which characterizes his type, is only privately known to him. When trading with the retailer, the supplier demands a reservation profit that depends on his unit production cost. We model this problem as a game of adverse selection. In this model, the retailer offers a menu of contracts, each of which consists of two parameters: the ordering quantity and the supplier's share of the channel pr...
• Competitive and Collaborative Quality and Warranty Management in Supply Chains AI翻译

  摘要：Product quality and product warranty coverage are two important and closely related operational decisions. A longer warranty protection period can boost sales, but it may also result in dramatically increased warranty cost, if product quality is poor. To investigate how these two decisions interact with each other and influence supply chain performance, we develop a single-period model with a supplier that provides a product to an original equipment manufacturer, which in turn sells it to cust...
• A Multi-Supplier Sourcing Problem with a Preference Ordering of Suppliers AI翻译

  摘要：We study a sourcing problem faced by a firm that seeks to procure a product or a component from a pool of alternative suppliers. The firm has a preference ordering of the suppliers based on factors such as their past performance, quality, service, geographical location, and financial strength, which are commonly included in a supplier scorecard system. Thus, the firm first uses available inventory from supplier 1, if any, then supplier 2, if any, and so on. The suppliers differ in costs and pr...
• Price and Service Competition in an Outsourced Supply Chain AI翻译

  摘要：We consider a buyer who outsources the manufacturing of a product to multiple symmetric make-to-stock suppliers who compete on price and service (fill rate). The buyer allocates demand to the suppliers using a score function with an exponential form, which specifies the relative importance of price vs. service, in order to minimize his costs, while the suppliers choose their prices and fill rates to maximize their profits. For the case of dual-sourcing, we characterize the optimal parameter of...
• Early Sales of Seasonal Products with Weather-Conditional Rebates AI翻译

  摘要：Some retailers of seasonal products adopt weather-conditional rebate programs to induce early sales and increase profits. In such promotions, customers who buy the product in an advance preselling period are offered rebates if a pre-specified weather condition is realized during the later normal selling season. We investigate the potential benefits of these programs for retailers. We show that the weather-conditional rebate program can increase sales by price discriminating among a customer's ...
• Manufacturer-Retailer Negotiations in the Presence of an Oligopolistic Input Market AI翻译

  摘要：When a manufacturer relies solely on its own inputs in making products, the focus of negotiations between the manufacturer and retailer is exclusively on profits in the output (retail) market. In such cases, absent retail competition concerns, standard two-part tariff negotiations set the per-unit wholesale price equal to marginal cost, and require fixed transfers from the retailer to the manufacturer. In this article, we recognize that manufacturers often rely on imperfectly competitive marke...
• Revenue Management with End-of-Period Discounts in the Presence of Customer Learning AI翻译

  摘要：Consider a firm that sells identical products over a series of selling periods (e.g., weekly all-inclusive vacations at the same resort). To stimulate demand and enhance revenue, in some periods, the firm may choose to offer a part of its available inventory at a discount. As customers learn to expect such discounts, a fraction may wait rather than purchase at a regular price. A problem the firm faces is how to incorporate this waiting and learning into its revenue management decisions. To add...
• Gray Markets, A Product of Demand Uncertainty and Excess Inventory AI翻译

  摘要：Diverting large quantities of goods from authorized distribution channels to unauthorized or gray market channels, albeit legal, significantly affects both firms and consumers due to effects on price, revenue, service and warranty availability, and product availability. In this paper we consider mechanisms by which the uncertainty surrounding inventory ordering decisions drives gray markets. We start with a minimal stochastic supply chain model composed of a producer and a retailer; then we re...

  摘要：Make-to-order (MTO) manufacturers must ensure concurrent availability of all parts required for production, as any unavailability may cause a delay in completion time. A major challenge for MTO manufacturers operating under high demand variability is to produce customized parts in time to meet internal production schedules. We present a case study of a producer of MTO offshore oil rigs that highlights the key aspects of the problem. The producer was faced with an increase in both demand and de...
