摘要：We consider a two-echelon inventory system with a capacitated centralized production facility and several distribution centers (DCs). Both production and transportation times are stochastic with general distributions. Demand arrives at each DC according to an independent Poisson process and is backlogged if the DC is out of stock. We allow different holding and backlog costs at the different DCs. We assume that inventory at DCs is managed using the one-for-one replenishment policy. The main ob...

摘要：Funding for humanitarian operations in the global health sector is highly variable and unpredictable. We study the problem of managing inventory in the presence of funding constraints over a finite planning period. Our goal is to determine the optimal procurement policy given the complexities associated with funding and also to analyze the impact of funding amount, funding schedule, and uncertainty around the funding timing on operations. We use a multiperiod stochastic inventory model with fi...

摘要：Display advertising is a $25 billion business with a promising upward revenue trend. In this paper, we consider an online display advertising setting in which a web publisher posts display ads on its website and charges based on the cost-per-click pricing scheme while promising to deliver a certain number of clicks to the ads posted. The publisher is faced with uncertain demand for advertising slots and uncertain traffic to its website as well as uncertain click behavior of visitors. We formul...

摘要：Many factors introduce the prospect of changes in the demand environment that a firm faces, with the specifics of such changes not necessarily known in advance. If and when realized, such changes affect the delicate balance between demand and supply and thus current prices should account for these future possibilities. We study the dynamic pricing problem of a retailer facing the prospect of a change in the demand function during a finite selling season with no inventory replenishment opportun...

摘要：In services, customers provide significant inputs into the production process. In particular, these inputs may be the customers themselves participating in the service delivery. Although many service firms have explored different ways of involving customers in their production process, there is no clear guideline for the design of such coproductive systems. In this paper, we develop an analytical model of joint production between a service provider and a customer and characterize how a service...

摘要：Hospital emergency departments (EDs) typically use triage systems that classify and prioritize patients almost exclusively in terms of their need for timely care. Using a combination of analytic and simulation models, we demonstrate that adding an up-front estimate of patient complexity to conventional urgency-based classification can substantially improve both patient safety (by reducing the risk of adverse events) and operational efficiency (by shortening the average length of stay). Moreove...

摘要：The use of multiattribute auctions for procurement of products and services when both price and quality matter is becoming more frequent. Such auctions often employ scoring rules and are open ended in winner determination. Yet there is a significant gap in the literature on the efficiency of these procurement mechanisms. In this paper, providing a theoretical model and utilizing data from legal service procurement auctions, we study how open-ended scoring auctions can be used effectively in pr...

摘要：We consider service systems with a finite number of customer arrivals, where customer interarrival times and service times are both stochastic and heterogeneous. Applications of such systems are numerous and include systems where arrivals are driven by events or service completions in serial processes as well as systems where servers are subject to learning or fatigue. Using an embedded Markov chain approach, we characterize the waiting time distribution for each customer, from which we obtain...

摘要：We consider revenue optimization in an M/M/1 queue with price and delay sensitive customers, and we study the performance of demand-independent pricing that does not require any arrival rate information. We formally characterize the optimal demand-independent price and its performance relative to pricing with precise arrival rate knowledge. We find that demand-independent pricing can perform remarkably well and its performance improves as customers become more delay sensitive. In particular, f...

摘要：A firm hires a consultant to acquire demand information. The outcome of information acquisition may turn out to be successful such that the firm learns much about the market demand, thus becoming informed, or unsuccessful such that it learns very little about the market demand, thus remaining uninformed. After the outcome becomes clear, the firm knows its information status, informed or uninformed, and the information content if informed. The client firm usually requires strict confidentiality...
