摘要：Using real data and process flows from two large hospitals (in Singapore and in Chengdu, China) as cases, we illustrate how to apply certain modeling and optimization techniques, along with simulation as a validation tool, to hospital resource planning problems. We demonstrate how these simple analytical tools can help achieve significant improvements in both patient service and resource utilization, and without the need to increase the overall level of existing capacities. Two resource planni...

摘要：As more customers purchase pre-owned apparel, firms are increasingly adopting resale based business models. These models typically operate as either (i) a trade-in and resale program, wherein a firm offers a trade-in discount on a new product and resells the traded-in products, or (ii) a P2P resale marketplace where customers can buy and sell used products to each other. Since different firms choose different resale strategies, it is not clear which strategy is more profitable. Furthermore, al...

摘要：This study aims to evaluate the cost of agents' self-routing in a service system with inbound and outbound customers. We assume that inbound customers arrive over time depending on the waiting time offered, while outbound customers can be contacted at all times. Furthermore, agents are in control of routing decisions and are aware of the state of the system. Accordingly, they decide whether to serve an inbound or outbound customer, or to idle. The system manager seeks to provide a suitable tra...

摘要：We consider an inventory control problem with lost-sales in a shifting demand environment. Over a planning horizon of T periods, demand distributions can change up to O( log T) times, but the firm does not know the demand distributions before or after each change, the time periods when changes occur, or the number of changes. Therefore, the firm needs to detect changes and learn the demand distributions only from historical sales data. We show that with censored demand, active exploration in t...

摘要：Studies show that merchants are heterogeneous in profitability from offering promotions on third-party-online-promotion marketplaces who often charge a single commission rate. Using a data analytics system, a marketplace can classify merchants according to their heterogeneous characteristics and offer merchant-type specific commission rates. In this study, we construct a game-theoretic model consisting a marketplace with two types of merchants who have heterogeneous proportion of consumers who...

摘要：Conceptualized as a meta-construct, operations-related structural flux (ORSF) refers to appointments and exits-voluntary or involuntary-of operations-related executives, to and from the firm. This research leverages the contingency theory perspective to show that ORSF's influence on firm performance is contingent on contextual circumstances of such executive changes, specifically, appointments and exits-voluntary or involuntary. Examining executive turnover data from North American public firm...

摘要：Firms increasingly need to manage uncertainty and become more agile and adaptable. This study considers how a multi-product firm can use its product mix, resource capacity allocation, and pricing decisions to manage challenges such as structural economic shifts or changes in consumers' willingness-to-pay. Firms that seek to develop and use such a product line face a fundamental trade-off. On the one hand, multiple products compete for the demand externally (i.e., cannibalization effects), as w...

摘要：The operations-finance interface (OFI) jointly optimizes material, monetary, and information flows under intricate sources of uncertainty. To sketch the broad landscape in this emerging and interdisciplinary field, this study synthesizes literature across diverse themes and dispersed methodologies, screens systematically the research progression from original foundations to recent contributions in each major research stream, and thereby advocates future research innovations on prospective topi...

摘要：We study a manufacturer's product preannouncement decision in a setting where there is uncertainty about when an innovative new product design will be finalized for production, and a key component supplier needs to reserve the capacity before the realization of the final product design. The marketing literature has shown that product preannouncement changes the product demand: it may create buzz about the new product so the demand increases; or it may induce stronger competition from rivals so...
