摘要：A new class of online services allows Internet media sites to direct users from articles they are currently reading to other content they may be interested in. This process creates a browsing path along which there is potential for repeated interaction between the user and the provider, giving rise to a dynamic optimization problem. A key metric that often underlies this recommendation process is the click-through rate (CTR) of candidate articles. Whereas CTR is a measure of instantaneous clic...

摘要：We present our work with an online retailer, Rue La La, as an example of how a retailer can use its wealth of data to optimize pricing decisions on a daily basis. Rue La La is in the online fashion sample sales industry, where they offer extremely limited-time discounts on designer apparel and accessories. One of the retailer's main challenges is pricing and predicting demand for products that it has never sold before, which account for the majority of sales and revenue. To tackle this challen...

摘要：We study an assembly system with a number of parallel multistage processes feeding a multistage final assembly process. Each stage has a stochastic throughput time. We assume that the system is controlled by planned leadtimes at each stage. From these planned leadtimes the start and due times of all stages can be derived. If a job finishes at a particular stage and has to wait before the start of the next job(s), a holding cost proportional to the waiting time is incurred. A penalty cost propo...

摘要：This paper proposes the Q-Lasso method for wait time prediction, which combines statistical learning with fluid model estimators. In historical data from four remarkably different hospitals, Q-Lasso predicts the emergency department (ED) wait time for low-acuity patients with greater accuracy than rolling average methods (currently used by hospitals), fluid model estimators (from the service operations management literature), and quantile regression methods (from the emergency medicine literat...

摘要：Practice-based research-research performed with the intent of improving the operation of a collaborating practitioner-is an important endeavor for our field: such work may reveal new problems, interesting phenomena, and may also generate data, educational material, and solutions to important practical problems. We argue that the practical relevance of any operations management (OM) research is driven by the two dimensions of generalizability and validity, which together offer a framework for c...

摘要：Do service provider efforts to educate customers influence customer outcomes? We analyze the outcome of a field experiment executed by a major public cloud infrastructure services provider in 2011. Out of 2,673 customers who adopted the service during the experiment, 366 received a service intervention: an engagement through which the provider offered initial guidance on how to use basic features of the service. Before execution, it was unclear if this proactive customer education would have p...

摘要：This paper studies the pricing strategies for personalized product bundles. In such problems, a seller provides a variety of products for which customers can construct a personalized bundle and send a request for quote (RFQ) to the seller. The seller, after reviewing the RFQ, has to determine a price based on which the customer either purchases the whole bundle or nothing. Such problems are faced by many companies in practice, and they are very difficult because of the potential unlimited poss...

摘要：Store liquidation is the time-constrained divestment of retail outlets through an in-store sale of inventory. The retail industry depends extensively on store liquidation, both to allow managers of going concerns to divest stores in efforts to enhance performance and as a means for investors to recover capital from failed ventures. Retailers sell billions of dollars of inventory annually during store liquidations. This paper introduces the store liquidation problem to the literature and presen...

摘要：We demonstrate the value of utility-based choice models to estimate demand and plan inventory for new and used textbooks in the presence of consumer choice and stockout-based substitution at a university textbook retailer. Demand information is censored, the exact time of stockout is not observed, and the short selling season often does not allow for replenishment. Using data for 26,749 book titles from 2007 to 2011 and a simulation experiment calibrated on real data, we show that an attribute...
