摘要：Blockchain-based track and trace (BCT) is increasingly adopted in the retail supply chain. However, there is little rigorous empirical evidence quantifying the effects of BCT on consumer purchases or examining the heterogeneity of these effects with varying product-related characteristics. Employing transactional data from a leading global e-retailer that contains 540 stock keeping units (SKUs), we design a quasi-natural experiment spanning 80 weeks to estimate the signaling effect of BCT (i.e...

摘要：Research has demonstrated that certain team composition factors-high expertise similarity, high network cohesion, and mixed-gender teams-have predominantly negative effects on the teams' invention outcomes. Yet these factors have also been shown to improve team coordination, which should (in theory) lead to better invention outcomes. We address this tension by highlighting the need to consider the invention's integrality, which increases task interdependencies among team members and thereby st...

摘要：In practice, lead time demand (LTD) can be skewed, multi-modal or highly variable, and these factors compromise the validity of typical approaches used for setting safety stock levels. Motivated by encountering this problem at our industry partner, we develop an approach for setting safety stock levels using the bootstrap, a widely used statistical procedure. Existing bootstrap approaches for inventory management either operate directly on observed LTD or assume deterministic lead times, permi...

摘要：This work addresses the issue of intelligent robot-human-coordinated parts-to-picker order fulfillment carried out in a human-friendly manner. One unique feature of the proposed approach involves integrating a real-time data-driven stochastic-dynamic model with a fatigue accumulation function. The optimal solutions help achieve coordination between human pickers and robots, such that robots can agilely adapt to the coordinated pickers' efficiency and fatigue conditions. Specifically, the propo...

摘要：The COVID-19 pandemic presented the world to a novel class of problems highlighting distinctive features that rendered standard academic research and participatory processes less effective in properly informing public health interventions in a timely way. The urgency and rapidity of the emergency required tight integration of novel and high-quality simulation modeling with public health policy implementation. By introducing flexibility and agility into standard participatory processes, we alig...

摘要：Firms in interorganizational networks are exposed to interdependent risks that are transferable across partner firms, such as contamination in food supply chains or data breaches in technology networks. They can be decomposed into intrinsic risks a firm faces from its own operations and extrinsic risks transferred from its partners. Firms have access to two security strategies: either they can independently eliminate both intrinsic and extrinsic risks by securing their links with partners or, ...

摘要：COVID-19 pandemic has revealed how unprepared operations and supply chain professionals are for abnormal conditions. Understanding how the production and operations management field can affect the trajectory and especially the remediation of pandemics is a critical, but understudied, area of research from descriptive, predictive, and prescriptive perspectives. Fourteen research articles in this special issue have attempted to fill this gap with rigor. We first summarize these articles in six c...

摘要：Products approaching the end of their shelf life on retail store shelves are more likely to result in food waste. For this reason, manufacturers establish shipping policies related to the age of the products that leave their warehouses, that is, they set a maximum age beyond which shipping to retail stores is no longer allowed. In practice, most existing policies are simple one-size-fits-all rules that do not accommodate the varying characteristics of the products. We offer a framework that ma...

摘要：The rise of contract farming has transformed millions of farmers' lives. We study a new class of contract farming problems, where the farmer holds superior information and can invest effort to improve productivity over time. Despite their prevalence, the literature offers little guidance on how to manage such farmers with dynamic incentives. We build a game-theoretic model that captures the dynamic incentives of learning and gaming, with hidden action and information. We characterize the optim...

摘要：We consider a dynamic Stackelberg game between a manufacturer and a retailer facing a randomly changing market environment (boom-bust cycle) modeled as a Markov process over time. The manufacturer announces the national advertising effort and a cooperative (co-op) advertising subsidy, and the retailer sets the local advertising effort. We derive the optimal feedback equilibrium advertising strategies and show that the channel members are forward-looking in their advertising decisions. In the s...
