摘要：In this paper, we explore why users' experiences with emerging supply chain technologies comprise inflated expectations followed by disappointment in the early stages of adoption, as per the Gartner Hype Cycle. We used affordance theory to study how managers perceive emerging technologies to explain their adoption experience. Affordance theory indicates that perceived benefits-and goals and constraints-depend on the interaction between technology and the users, not on the technology alone. Fir...

摘要：We study a vacation queueing model where an arriving customer, upon finding the server to be on vacation, is offered an opportunity to pay a fee to instantaneously end the server's vacation, which is referred to as pay-to-activate-service (PTAS). If no one utilizes PTAS, the service will automatically resume when the system's workload reaches a critical level. We investigate customers' equilibrium strategies: (i) joining or balking and (ii) if joining, accepting PTAS or rejecting PTAS, in resp...

摘要：Online user-generated reviews have received significant importance in the literature as they help consumers make consumption decisions. However, despite significant developments in this domain in the past decade, little attention has been paid to how narrative aspects of reviews affect consumers' consumption decisions and, consequently, influence sales. A narrative can be defined as a sequentially structured discourse that provides an understanding of the events that unfold around the narrator...

摘要：This paper considers a single-stage make-to-stock production-inventory system under random demand and random yield, where defective units are reworked. We examine how to set cost-minimizing production/order quantities in such imperfect systems, which is challenging because a random yield implies an uncertain arrival time of outstanding units and the possibility of them crossing each other in the pipeline. To determine the order/production quantity in each period, we extend the unit-tracking/de...

摘要：Ending the HIV/AIDS epidemic is an important target of the United Nations Sustainable Development Goals (SDGs). To achieve it, countries worldwide donate large amounts of development aid (USD 15.18 billion annually). However, current practice in allocating development aid is largely based on decision heuristics and thus subject to inefficiencies. To address this problem, we aim to support managers of funding bodies in identifying cost-effective allocations of development aid and thus develop a...

摘要：In recent years, research on supply chain coordination (SCC) with risk-averse agents has received much attention. Previous studies are primarily concerned with the coordination of a single manufacturer-single retailer supply chain using different definitions of SCC. What is lacking is a comprehensive analysis of the achievability of SCC. In this paper, we provide a systematic analysis of SCC with risk-averse agents. We see that three definitions of SCC have been proposed in the literature to i...

摘要：Sellers are conventionally generous with their return policies for valuation-uncertain products, such as experience products and new products. However, with the development of online review platforms, an increasing number of consumers are engaging in social learning by referring to others' reviews to reduce valuation uncertainty. In this study, we investigate how social learning interacts with sellers' return policies. There are three main conclusions. First, when sellers have a relatively hig...

摘要：In 2020, inventory shrinkage eroded $61.7 billion profit in the U.S. retail industry. Unfortunately, fighting inventory shrinkage to protect retailers' already slim profits is challenging due to unknown shrinkage rates and invisible inventory levels. While the latter has been studied in the literature, the former has not. To deal with this challenge, we introduce two new features to the Bayesian inventory models: (1) interleaving customer and theft arrival processes that contribute to actual s...

摘要：The unprecedented rate at which data are being generated has led to the growth of data markets where valuable data sets are bought and sold. A salient feature of this market is that a data-buyer (agent) is endowed with multidimensional private information, namely, her ideal record that she values the most and how her valuation for a given record changes as its distance from her ideal record changes. Consequently, the revenue-maximization problem faced by a data-seller (principal), who serves m...

摘要：We study the relationship between workload and the test ordering behavior of physicians in an operational context where examination can be finished with a test order. We define workload in two forms: the unfinished workload, that is, the work waiting to be completed, and the finished workload, that is, the already completed work since the beginning of the work day. We investigate their effect on the probability of a test order and the number of tests ordered for a patient who receives a test o...
