摘要：Popular tariffs in the telecommunications market, such as three-part tariffs and flat-rate plans, specify an allowance below which customers enjoy a free and high-quality service. When they consume beyond the allowance, customers either need to pay for the overage (under three-part tariffs) or receive a degraded service (under flat-rate plans), thus experiencing an overage disutility. Some network service providers have recently begun to allow data trading among their subscribers, who can now ...

摘要：We consider a periodic-review perishable inventory system with multiple demand classes, each characterized by a different lost-sales cost and the least freshness requirement. Demands of different classes in the same period could be correlated, while demands across periods are independent but not necessarily identical. In each period, the firm jointly makes the decisions regarding demand fulfillment, production/ordering, and disposal. The objective is to minimize the total discounted expected c...

摘要：We consider a surgical case scheduling problem with the objective of minimizing the expected time span of the schedule subject to a prespecified upper bound on the expected waiting time for each patient. The problem is challenging due to its combinatorial and nonlinear nature, and we focus on developing approximate methods to solve the problem. Specifically, we study two approximation methods. In the certainty equivalent method, we approximate the expected time span of the cases by assuming th...

摘要：Recent advancements in Information Technology have provided an opportunity to significantly improve the effectiveness of inventory systems. The use of in-cycle demand information enables faster reaction to demand fluctuations. In particular, for the newsvendor (NV) system, we exploit the newly available data to perform an additional review (AR) of inventory at an endogenously determined, a priori set time during the sales period, and perform an additional replenishment if necessary. We impleme...

摘要：In this paper, we honor Stanford University Professor Hau Lee, who is a great inspiration and thought leader in the supply chain and operations management (SC&OM) field. Our discussion centers around one of the most challenging SC&OM problems-food production, distribution, and consumption from dirt to table. We advocate and link our notions of emergent regenerative, organic food value chains (ROFVC) with quadruple-aim performance (QAP) that connects financial outcomes with ecological, human, a...

摘要：We study a multi-period inventory allocation problem in a one-warehouse multiple-retailer setting with lost sales. At the start of a finite selling season, a fixed amount of inventory is available at the warehouse. Inventory can be allocated to the retailers over the course of the selling horizon (transshipment is not allowed). The objective is to minimize the total expected lost sales and holding costs. In each period, the decision maker can use the realized and possibly censored demand obser...

摘要：For global shippers (i.e., multinational manufacturers or retailers), strategic sourcing of container liner shipping services from ocean carriers is an important element of successful global supply chain management. We study how to utilize information about different ocean carriers' liner service schedules so that shippers can optimize their sourcing decisions over the selection of carriers to transport container cargoes around the world through multiple shipping lanes. We first introduce a de...

摘要：Agriculture value chains are going through a paradigm shift, from efficiency-driven industrial agriculture to resilience-focused eco-friendly agriculture. The nature of the paradigm shift is, to a certain extent, similar to the transformation taking place in many other industries (Lee 2014); its impact on the environment is, however, far-reaching. This study intends to raise awareness of the challenges and trends in agriculture value chains and explores research opportunities through which ope...

摘要：This study considers the product development process for a start-up that relies on equity-based incentives to motivate effort by vendors who are hired to contribute to the development process. We study how the organizational structure of the start-up affects the choice between sequential and concurrent development using a two-task model, in which both tasks must be completed for the start-up to earn revenue. We study several organizational structures, which differ in terms of task allocation, ...
