摘要：In this paper, we reflect on the supply chain issues and operational challenges that we experienced through the various stages of the Covid-19 pandemic. We identify some phenomena that were attributable in some way to the pandemic, and apply core principles of operations management, and a simple numerical model, to explain and understand their occurrence. We highlight some key lessons and discuss implications for supply chain design and planning, to prepare for the next global disruption.

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：As software-as-a-service (SaaS) becomes an increasingly popular business model, free-trial acquisition, which allows prospective consumers to explore the service at no charge, also becomes a norm for SaaS companies. However, empirical research on the role of marketing communications, consumers' free-trial usage, and their interactions is still lacking. This study utilizes the granular data from a leading SaaS firm that provides prospects with free trials and examines the impact of and interact...

摘要：Motivated by the need of small and medium-sized hospitals to improve their platelet inventory management and achieve best practices, we consider an inventory system for a perishable product with a three-period shelf life over a finite horizon. In the system, the regular replenishment in each cycle is supplemented by an inventory adjustment opportunity in mid-cycle involving expedited orders and returns. We show that an optimal regular replenishment policy is an (s, S, S(x)) policy. Namely, if ...

摘要：Cross-training is an important tool to improve the performance of manufacturing and service systems through dynamic worker allocation. This study investigates how cross-training can be leveraged when worker collaboration is not possible and frequent worker reassignment is undesirable. We consider a tandem queueing system with finite buffers between tasks. We show that if each worker is the fastest at a different task, then the optimal policy is always dedicated, regardless of the magnitude of ...

摘要：Real social information is believed to cause a trust-privacy paradox in e-commerce platforms, with the degree of information disclosure affecting platform performance. In this study, we split the mixed influence into the direct trust mechanism and the indirect privacy mechanism, studying each in the context of partial and full social information disclosure, respectively. Using unique data from an 80-day large-scale online experiment conducted in an e-commerce platform in China, we show that a ...

摘要：Many decisions must be made before relevant uncertainties are revealed; hence robustness approaches to decision making are often considered. There are two major approaches to robustness in the literature: (i) maximizing the value of the worst outcome and (ii) minimizing the maximum ex post regret of the decision. While the first approach seeks the best worst-case outcome, it may result in substantial opportunity losses relative to the ex post optimal decision; this is particularly critical in ...
