摘要：Discrete choice models are appealing for airline revenue management (RM) because they offer a means to profitably exploit preferences for attributes such as time of day, routing, brand, and price. They are also good at modeling demand for unrestricted fare class structures, which are widespread throughout the industry. However, there is little empirical research on the practicality and effectiveness of choice-based RM models. Toward this end, we report the results of a study of choice-based RM...

摘要：Pipelines play a critical role in matching the supply and demand of natural gas. The pricing of their capacity is an important problem in practice for pipeline companies and the users of this capacity, which include shippers such as natural gas merchants, producers, and local distribution companies. This paper conducts a normative analysis of how pipeline capacity should be priced by each of these players. Although the trading value of this capacity should be relevant to merchants and its subs...

摘要：We propose an extension of the competitive newsvendor model to investigate the impact of quick response under competition. For this purpose, we consider two retailers that compete in terms of inventory: customers that face a stockout at their first-choice store will look for the product at the other store. Consequently, the total demand that each retailer faces depends on the competitor's inventory level. We allow for asymmetric reordering capabilities, and we are particularly interested in th...

摘要：In some supply chains, materials are ordered periodically according to local information. This paper investigates how to improve the performance of such a supply chain. Specifically, we consider a serial inventory system in which each stage implements a local reorder interval policy; i.e., each stage orders up to a local base-stock level according to a fixed-interval schedule. A fixed cost is incurred for placing an order. Two improvement strategies are considered: (1) expanding the informatio...

摘要：The literature on many-server approximations provides significant simplifications toward the optimal capacity sizing of large-scale monopolists, but falls short of providing similar simplifications for a competitive setting in which each firm's decision is affected by its competitors' actions. In this paper, we introduce a framework that combines many-server heavy-traffic analysis with the notion of epsilon-Nash equilibrium and apply it to the study of equilibria in a market with multiple larg...

摘要：We study cross-selling operations in call centers. The following questions are addressed: How many customer-service representatives are required (staffing), and when should cross-selling opportunities be exercised (control) in a way that will maximize the expected profit of the center while maintaining a prespecified service level target? We tackle these questions by characterizing control and staffing schemes that are asymptotically optimal in the limit, as the system load grows large. Our ma...

摘要：We study a profit-maximizing firm providing a service to price and delay sensitive customers. We are interested in analyzing the scale economies inherent in such a system. In particular, we study how the firm's pricing and capacity decisions change as the scale, measured by the potential market for the service, increases. These decisions turn out to depend intricately on the form of the delay costs seen by the customers; we characterize these decisions up to the dominant order in the scale for...

摘要：Independent parties that produce perfectly complementary components may form alliances (or coalitions or groups) to better coordinate their pricing decisions when they sell their products to downstream buyers. This paper studies how market demand conditions (i.e., the form of the demand function, demand uncertainty, and price-sensitive demand) drive coalition formation among complementary suppliers. In a deterministic demand model, we show that for an exponential or isoelastic demand function,...
