摘要：Firms dread product recalls. Consequently, firm leaders may take steps to avoid recalls when possible, or to avoid the blame for them when there is someone else to blame. We analyze how the appointment of a new chief executive officer (CEO) for a firm in the consumer product industry influences the hazard of subsequent recalls initiated by that firm. Using 25 years of consumer product industry data, including 125 publicly traded firms that experienced 307 new CEOs and 584 voluntary recalls fro...

摘要：Intelligent part-to-picker systems are spreading across a broad range of industries as preferred solutions for agile order fulfillment, wherein mobile racks are carried by robots and moved to stations where human pickers can pick items from them. Such systems raise the challenge of designing good work schedules for human pickers; they also give rise to a new class of operational scheduling problems in human-robot coordinated order picking systems. This work studies the problem of finding a sui...

摘要：Investments in infrastructure platforms aim to enhance supply chain performance. We build on network-based models of platform growth to characterize configurations of digital and physical supply chain infrastructure. We define cross-platform effect as the value accrued by a platform on one side of a multiplatform configuration as capability for the opposite side platform evolves. We posit that aligning cross-platform effect across digital and physical infrastructure enhances system outcomes. O...

摘要：Long-term vision depends on history, and on history alone. Scholarship in technology, manufacturing, and operations management is incomplete without a knowledge of history. In chronicling the history of technology, knowledge, and manufacturing, we have traced the remarkable continuity in the evolution of humans from hominins to homo sapiens, in the migration of homo sapiens from Africa to the furthest reaches of the world, and in the rise of civilizations and industrialization driven by agricu...

摘要：The accumulation of experience that occurs with production is likely to impact an organization's ability to develop manufacturing process innovations. However, how different types of manufacturing experience relate to the characteristics of an organization's process innovation output is an open question. In this study, we investigate how a firm's accumulated related and unrelated manufacturing experiences are associated with this firm's ability to innovate its production methods. To characteri...

摘要：We consider a context-based dynamic pricing problem of online products, which have low sales. Sales data from Alibaba, a major global online retailer, illustrate the prevalence of low-sale products. For these products, existing single-product dynamic pricing algorithms do not work well due to insufficient data samples. To address this challenge, we propose pricing policies that concurrently perform clustering over product demand and set individual pricing decisions on the fly. By clustering da...

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...

摘要：Overdiagnosis of breast cancer, defined as diagnosing a cancer that would otherwise not cause symptoms or death in a patient's lifetime, costs U.S. health care system over $1.2 billion annually. Overdiagnosis rates, estimated to be around 10%-40%, may be reduced if indolent breast findings can be identified and followed with noninvasive imaging rather than biopsy. However, there are no validated guidelines for radiologists to decide when to choose imaging options recognizing cancer grades and ...

摘要：Substitution is a commonly adopted strategy for matching the demand mix by appropriately allocating the supplies. The recent development of information technology has allowed firms to easily swap products to meet consumers' preferences. When formulating substitution policies, firms have to take into account the supply and demand conditions, as well as the cost and benefit of substitution. We formulate a dynamic model, in which the firm replenishes the product inventories from uncertain sources...

摘要：In this study, we examine how firms can leverage reference-group effects (RGEs) in sequential introduction of upgraded products. RGEs arise when consumers engage in social comparisons: leaders desire to distinguish themselves from followers and followers desire to mimic leaders. We find that RGEs have a non-monotonic impact on the profitability of product upgrades: a stronger RGE first increases and then decreases profits. This inverted-U effect is fundamentally driven by two opposite effects ...
