摘要：By providing useful product information from the perspective of other buyers, online product/service reviews can help customers better evaluate the true quality of products and judge whether a product is a good fit for them. Based on online reviews, firms may improve product quality and/or adjust selling price to compete with other firms. In this study, we investigate the effects of online reviews on product quality and pricing decisions in a duopoly market that consists of two competing firms...

摘要：Motivated by the potential growth of capacity markets due to 3-D manufacturing, we examine the integration of long- and short-term contracts for a capacity marketplace. In the marketplace, manufacturers and suppliers first participate in long-term contracts in which manufacturers reserve capacity at one or more suppliers. Subsequently, manufacturers and suppliers trade in a spot market to fulfill residual demand and sell residual capacity, respectively; in the spot market, the equilibrium pric...

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：A total minimum commitment contract is a supply contract under which a firm commits to buying a minimum quantity of a product from its supplier during the contract duration (e.g., 1 year). Such contracts are widely used in industries, because they provide the buyer with flexibility in terms of the timing and size of each order and the supplier with a guaranteed total order volume. Previous studies on such contracts have focused primarily on the firm's inventory decisions, and none of them has ...

摘要：A dramatically changing business landscape characterized by volatility and uncertainty (which in turn are driven by unpredictable alterations of conditions by such factors as geopolitical events, climate changes, disasters-natural and human causes, reduction in food, potable water, and critical materials supply along with environmental contamination), has created a situation whereby a rethink of Production and Operations Management (POM) strategies and practices is considered timely and approp...

摘要：Does the news media's reporting of the safety (or the lack thereof) of a firm's products impact managers' voluntary recalls of the products? The current article empirically answers this question in the context of safety defects in vehicles of 22 manufacturers from June 2009 to December 2020 in the United States. Results show that the volume of news reports about safety in a manufacturer's products increases voluntary recalls by managers. Further, the negativity in these news reports strengthen...

摘要：We study the problem of advance scheduling of ward admission requests in a public hospital, which affects the usage of critical resources such as operating theaters and hospital beds. Given the stochastic arrivals of patients and uncertain usage of resources, it is often infeasible for the planner to devise a risk-free schedule to meet these requests without violating resource capacity constraints and creating adverse effects that include healthcare overtime, long patient waiting times, and be...

摘要：Technology, market, and competitive dynamics are requiring firms in restaurant/food service supply chains to improve their analytics capabilities, which have tended to lag behind other comparable industries. The global COVID-19 pandemic has further encouraged industrial leaders to evaluate new challenges and opportunities. Our research provides insights into current applications of analytics technologies and organizationally integrates these insights for decision-makers in restaurant supply ch...

摘要：Motivated by a realworld practice of a China Post sortation center, this study considers the deployment of Internet of Things (IoT) technology to improve the efficiency of a human-robot hybrid sortation system. In this system, IoT technology enables responsive adjustment of the manual capacity to alleviate the congestion effect of increasing parcel flow on robotic sorting efficiency. We begin with a predictive analysis of a real-life dataset to quantify the congestion effect on robotic sorting...

摘要：Many operations are characterized by a trade-off between speed and quality. This calls for an exploration of effective strategies to balance the two metrics. This study investigates the separate and joint effect of quantity and quality feedback on both performance metrics in order picking. We collected data from two real-effort experiments with in total 212 participants, who conducted an order picking task in an experimental warehouse. The results of the main experiment show that giving only q...
