摘要:Many field office leaders contend that authoritarian leadership improves the performance of humanitarian operations. The common narrative is that authoritarian leadership helps aid workers more quickly adapt to changes and thus deliver better job performance (e.g., by improving operations in their field office). However, given that field reports often highlight extant leadership as the source of serious operational failures, could leaders with an authoritarian style be part of the problem? We ...

摘要:In the Industry 4.0 era, automation and data analytics emerge as the major forces to enhance efficiency in operations management (OM). Disruptive technologies, such as artificial intelligence, robotics, blockchain, 3D printing, 5G, Internet-of-Thing, digital twins, and augmented reality, are widely applied. They potentially will bring a radical change to real world operations. In this study, we first explore several major disruptive technologies, examine the corresponding OM studies, and highl...

摘要:Blockchain is a prominently discussed technology in operations and supply chain management and firms increasingly engage in blockchain initiatives. Yet, an understanding of the technology's financial value remains elusive. Based on 175 firm announcements between 2015 and 2019, we conduct an international event study to estimate the impact of blockchain initiatives on the market value of the firm. We empirically demonstrate that blockchain announcements are associated with a significant average...

摘要:Physicians caring for chronically ill individuals need to predict patients' disease progression, as accurate disease projections can facilitate better treatment decisions. The power of prediction is prevention, as it is easier to prevent than to reverse. In this research, we propose a data-driven model for accurate and fast disease trajectory prediction, using electronic health records (EHRs) from Veterans Affairs Hospitals. EHRs contain tremendous amount of frequently updated, highly dimensio...

摘要:The role of information technology (IT) in managing operations that support environmentally sustainable growth has been emphasized a lot in operations management and information systems research. In this paper, we study the impact of the IT-based on-demand ridesharing platforms on an important aspect of sustainability-traffic congestion. Our theoretical prediction suggests two countervailing effects from the entry of ridesharing platforms to urban areas: the efficiency-enhancing effect that re...

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 ...
