摘要：What are the attributes of the best-performing supply chains? According to Lee (2004), the best supply chains are agile, adaptable, and ensure the interests of all participating companies stay aligned, that is, The Triple-A framework. Fifteen years later, we find global supply chains exposed, with an increasing frequency and alarming severity, to low probability disruptive shocks. We revisit the question of the current attributes of best-performing supply chains in a highly uncertain and risk ...

摘要：In his 2004 article, Professor Hau Lee argues that the best supply chains are not only fast and cost-effective but also agile, adaptable, and aligned. The concept of triple-A supply chains has been extensively studied in academic and trade publications and integrated into numerous operations and supply chain management curricula. It has also influenced the management approach of leaders around the world. Yet since the triple-A concept was first developed, supply chains have become increasingly...

摘要：Dual channel distribution benefits upstream manufacturers but may irritate downstream retailers. The channel conflict only seems to aggravate when retailers are put at information disadvantage. We show this need not be the case. (i) We demonstrate upstream private information can improve channel efficiency and consumer surplus. The main mechanism is the offsetting interplay of signaling distortion and double marginalization: with private selling cost, the manufacturer may signal her cost by cu...

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...
