摘要:Problem definition: Considering a mix of prepositioning and local purchasing, common to cover humanitarian demands in the aftermath of a rapid-onset disaster, we propose policies to determine preposition stock. These formulations are developed in the presence of demand, budget, and local supply uncertainties and for single-items delivery. Academidpractical relevance: The immediate period aftermath of a disaster is the most crucial period during which humanitarian organizations must supply reli...

摘要:Problem definition: For the standard newsvendor problem with an unknown demand distribution, we develop an approach that uses data input to construct a distribution ambiguity set with the nonparametric characteristics of the true distribution, and we use it to make robust decisions. Academic/practical relevance: Empirical approach relies on historical data to estimate the true distribution. Although the estimated distribution converges to the true distribution, its performance with limited dat...

摘要:Problem definition: We consider an intermediary's problem of dynamically matching demand and supply of heterogeneous types in a periodic-review fashion. Specifically, there are two disjoint sets of demand and supply types, and a reward for each possible matching of a demand type and a supply type. In each period, demand and supply of various types arrive in random quantities. The platform decides on the optimal matching policy to maximize the expected total discounted rewards, given that unmat...

摘要:Problem definition: Autonomous sensors connected through the Internet of things (IoT) are deployed by different firms in the same environment. The sensors measure an important operating-condition state variable, but their measurements are noisy, so estimates are imperfect. Sensors can improve their own estimates by soliciting estimates from other sensors. The choice of which sensors to communicate with (target) is challenging because sensors (1) are constrained in the number of sensors they ca...

摘要:Problem definition: We explore the impacts of store-brand (SB) introduction on multilateral contracting in vertical supply relationships that involve two upstream national-brand manufacturers (NBMs) selling through a common retailer. Two different information structures are scrutinized: simultaneous (secret offers) versus sequential contracting (public offers), essentially different timing by which the NBMs contract with the retailer. Academic/practical relevance: SB products are prevalent now...

摘要:Problem definition: Operational disruptions can impact a firm's risk, which manifests in a host of operational issues, including a higher holding cost for inventory, a higher financing cost for capacity expansion, and a higher perception of the firm's risk among its supply chain partners. Academic/practical relevance: Although disruptions have been studied extensively in the operations management literature, the emphasis has been on mitigating the deleterious impact on the firm's production po...

摘要:Problem definition: We consider the intraday scheduling problem in a group of orthopaedic clinics where the planner schedules appointment times, given a sequence of appointments. We consider patient re-entry-where patients may be required to go for an x-ray examination, returning to the same doctor they have seen-and variability in patient behaviours such as walk-ins, earliness, and no-shows, which leads to inefficiency such as long patient waiting time and physician overtime. Academic/practic...

摘要:Problem definition: This paper examines the impact of nonrandomness on random choice models and studies various operations problems under the new discrete choice models. Academic/practical relevance: The literature often assumes that the random utility components follow some independent and identically distributed distribution. This assumption is too restrictive in some real-world scenarios, because, for example, consumers may have known well about the attribute values for the product that the...

摘要:Problem definition: We study supply chain coordination in a setting with transshipment. We use centralized and decentralized transfer prices as a way to increase supply chain coordination. Academic/practical relevance: The ability to transship can improve channel efficiency by improving the match between supply and demand. We study how human decision makers behave in this setting and provide clear insights to improve coordination. Methodology: We use controlled laboratory experiments with fina...

摘要:Problem definition: This paper investigates the threshold effects on the consideration set formation for consumers and the associated pricing decisions for firms. Academic/practical relevance: In the class of random utility maximization choice models, consumers choose the alternative with the largest utility after resolving utility uncertainties for all options. However, in practice, consumers may not inspect all available alternatives due to bounded rationality or search cost. Methodology: Th...
