摘要：The view that adopting an environmental perspective on operations can lead to improved operations is in itself not novel; phrases such as lean is green are increasingly commonplace. The implication is that any operational system that has minimized inefficiencies is also more environmentally sustainable. However, in this paper we argue that the underlying mechanism is one of extending the horizons of analysis and that this applies to both theory and practice of operations management. We illustr...

摘要：A fundamental decision for any manufacturer is when to sell to a downstream retailer. A manufacturer can sell either early, i.e., well in advance of the selling season, or late, i.e., close to the selling season. This paper examines the impact of information asymmetry, retailer sales effort, and contract type on the manufacturer's sale-timing decision. We find that if information is symmetric, demand is not influenced by sales effort, and the contract specifies that the price paid is linear in...

摘要：We examine the competition between procurement auctions and long-term relational contracts that emerges from the increased usage of electronic marketplaces. Procurement auctions create supply chain efficiencies by selecting the least costly bidder, and long-term relational contracts ensure the quality of the procured products or services when these have nonverifiable attributes. The following two-layer supply chain model is analyzed: Suppliers of an industrial part with nonverifiable quality t...

摘要：Many firms in the business-to-consurner market sell identical products online using auctions and posted prices at the same time. In this paper, we develop and analyze a model of the key trade-offs sellers face in such a dual-channel setting built around the optimal choice of three design parameters: the posted price, the auction lot size, and the auction duration. Our results show how a monopolist seller can increase his revenues by offering auctions and a fixed price concurrently, and we iden...

摘要：T he service system design problem seeks to locate a set of service facilities, allocate enough capacity, and assign stochastic customer demand to each of them, so as to minimize the fixed costs of opening facilities and acquiring service capacity, as well as the variable access and waiting costs. This problem is commonly known in the location literature as the facility location problem with immobile servers, stochastic demand, and congestion. It is often set up as a network of M/M/1 queues an...

摘要：We show the existence of Nash equilibria in a Bertrand oligopoly price competition game using a possibly asymmetric attraction demand model with convex costs under mild assumptions. We show that the equilibrium is unique and globally stable. To our knowledge, this is the first paper to show the existence of a unique equilibrium with both nonlinear demand and nonlinear costs. In addition, we guarantee the linear convergence rate of tatonnement. We illustrate the applicability of this approach w...

摘要：Consider two markets of different sizes but similar costs and fare structure. All other things being equal, is an airline's expected revenue larger in the market with larger demand? If not, under what circumstances is it possible to compare expected revenues without carrying out a detailed analysis? In this article, we provide answers to these questions by studying the relationship between the optimal expected revenue and the demand distributions when the latter are comparable according to var...

摘要：A mathematical model is developed to help analyze the benefit in contact-center performance obtained from increasing employee (agent) retention, which is in turn obtained by increasing agent job satisfaction. The contact-center performance may be restricted to a traditional productivity measure such as the number of calls answered per hour, or it may include a broader measure of the quality of service, e.g., revenue earned per hour or the number of problems successfully resolved per hour. The ...

摘要：This paper studies a two-echelon assembly system and explores several important issues in managing decentralized supply chains. First, we investigate the behavior of the assembly system under decentralized control. It is shown that the Nash equilibrium of the competitive assembly system exists but is never system optimal. Next, we examine the role of information in the assembly system. We consider horizontal information sharing on the inventory status between the suppliers and demonstrate when...

摘要：W e study determining prices and production jointly in a multiple period horizon under a general, nonstationary stochastic demand function with a discrete menu of prices. We assume that the available production capacity is limited and that unmet demand is lost. We incorporate discretionary sales, when inventory may be set aside to satisfy future demand even if some present demand is lost. We analyze and compare partial planning or delayed strategies. In delayed strategies, one decision may be ...
