摘要：Increasingly, donors that subsidize socially-desirable products in the developing world are shifting from distributing through non-commercial to commercial channels, ceding control of the product price to for-profit intermediaries. This study advises a donor as to how the donor's loss of price control and the level of consumer awareness-defined as the fraction of the consumer population that is informed of the product's benefits-influence the donor's optimal subsidy and utility: First, in shif...

摘要：Should a seller make information about its products readily accessible to customers, so that customers do not have to incur any substantive cost-in terms of time and effort-to learn about those products? To help answer this question, we consider a monopolist selling two substitute products to a population of customers, who have differing tastes about the products. Each customer a priori has uncertainty about whether or not he will like each of the products. The seller may choose to make produc...

摘要：We develop a model of oligopoly competition involving innovation effort, market entry and production flexibility under demand uncertainty. Several heterogeneous firms make efforts to develop new prototypes; if they succeed, they hold a shared option to enter a new market under stochastic demand. We derive analytic results for the Markov perfect equilibrium accounting for development effort, market entry and production decisions and complement these by numerical analyses. Firm value-which embed...

摘要：In community health programs implemented in underserved areas, community healthcare workers (CHWs) prevent, diagnose, and treat the most common diseases. To ensure continuous in-service training of CHWs, some countries have mentored highly skilled CHWs to become supervisors. Designing a network in such a context implies determining the number of CHWs and supervisors, as well as the routing of the supervisors. This can be defined as a location-routing covering problem (LRCP), a variant of the l...

摘要：Despite the fact that hospital care is often delivered in successive stages, current healthcare scheduling and capacity planning methods usually treat different hospital units in isolation. To address such a shortcoming, we introduce the first Markov decision process model for scheduling surgical patients on a daily basis, explicitly taking into account patient length-of-stay in hospital after surgeries and inpatient census. By way of a simple and yet innovative variable transformation, we rev...

摘要：The Keogh Report of 2013 proposed a major reconfiguration of the accident and emergency (A&E) system under National Health Service (NHS) England to improve service. The proposed reconfiguration includes centralized facilities with multiple specialties as well as small local minor-injury facilities. We use stylized queuing models to analyze cost and service implications of the proposed reconfiguration. We find that increasing numbers of specialty patients that require admission to hospital make...

摘要：The present study investigates the benefit of joint decision making regarding whole blood collection and platelet production at a blood center. We consider a blood center that faces two types of platelet demands, differing in their freshness requirements and shortage penalty costs. We fully characterize the structure of the optimal policy regarding whole blood collection, platelet production, and inventory issuing, rationing and disposal. We find that the optimal platelet production quantity i...

摘要：This paper analyzes the business-to-business transactions in which a supplier sells assortments of used products to third-party remanufacturers. The supplier offers used products in different quality conditions, called grades. We model this buyer-supplier transaction as a Stackelberg game in which the buyer chooses his optimal purchase quantity of various grades, and the supplier chooses the optimal assortment and the prices of the grades in the assortment anticipating buyer's behavior. We fir...

摘要：In this paper, we study an analytical approach to selecting expansion locations for retailers selling add-on products whose demand is derived from the demand for a separate base product. Demand for the add-on product is realized only as a supplement to the demand for the base product. In our context, either of the two products could be subject to spatial autocorrelation where demand at a given location is impacted by demand at other locations. Using data from an industrial partner selling add-...

摘要：For many products, consumers need to physically experience them in order to assess their own valuations. We study how the equilibrium pricing among competing retailers depend upon assortments when consumers must search for this sort of fit information and are heterogeneous in their shopping behaviors. Specifically, we consider a market that consists of two retailers and two possible products. A consumer is either loyal to one of the retailers or is a shopper who follows a rational dynamic sear...
