摘要：We consider a single-period manufacturing problem wherein a risk-neutral manufacturer procures product components from an upstream supplier. Component quality is uncertain. Dysfunctional components result in defective products associated with an external failure cost. There is external financing pressure related to financial stress. The manufacturer can use the internal cash-flow and a collateralized loan to manage product quality risk through incoming inspection, business insurance, and cash ...

摘要：Empirical research in operations management (OM) has made rapid strides in the last 30 years, and increasingly, OM researchers are leveraging methods used in the econometrics and statistics literature to assess the causal effects of interventions. We discuss the two key challenges in assessing causality with observational data (i.e., baseline bias, differential treatment effect bias) and how dominant identification approaches such as matching, instrumental variables, regression discontinuity, ...

摘要：Live-stream selling is becoming increasingly popular in e-commerce platforms, where streamers sell products through real-time interactions, while consumers make purchases during live-stream time. We identify several important factors to evaluate the live-stream selling: (1) the streamer's ability to sell, which brings an extra value to consumers through real-time illustrations and social interactions; (2) whether the extra value is positively or negatively correlated to consumers' preference v...

摘要：This paper considers a single-stage make-to-stock production-inventory system under random demand and random yield, where defective units are reworked. We examine how to set cost-minimizing production/order quantities in such imperfect systems, which is challenging because a random yield implies an uncertain arrival time of outstanding units and the possibility of them crossing each other in the pipeline. To determine the order/production quantity in each period, we extend the unit-tracking/de...

摘要：Hunger occurs in all locations around the globe, from developing to developed countries. In fact, there were over 37 million food insecure individuals (those without access to consistent nutritious food) in the United States in 2018, and this number increased in recent years due to the COVID pandemic. In many countries, food banks are used to consolidate food donations from individuals or government agencies and then provide that food to local partner agencies (such as food pantries and soup k...

摘要：Besides using earmark budget to support farmer cost subsidies, governments in many developing countries use minimum support price (MSP) as an alternative subsidy scheme to (i) safeguard farmers' incomes against vagaries in crop price and (ii) ensure sufficient crop production. Among different MSP schemes, we focus on the credit-based MSP scheme under which a government will not take any possession of a crop; instead, it will credit farmers if the prevailing market price is below the prespecifi...

摘要：In recent years, our field has seen an increase in research that explicitly emphasizes an objective of social impact in the most unprivileged parts of the world-the so-called global base of the pyramid (BOP; referring to the 2.7 billion people living on less than $2.50 per day, the largest but most resource-poor economic group globally). This trend seems to cut across the traditional application areas of operations management (OM) and operations research (OR), and it coincides with an increase...

摘要：Service-level requirements play a crucial role in eliminating stock-outs in a production pipeline. However, delivering a specific service level can become an unattainable goal given the various uncertainties influencing both the production pipeline and customer demand and causing the manufacturer to adapt the initial strategy in response to disruptions. Such deviations from optimality frequently result in unexpected (and potentially very high) costs and are complex to manage. On the one hand, ...

摘要：Consumers are becoming more knowledgeable about companies' social responsibility (SR) practices. As a result, they are increasingly skeptical when companies do not provide clear information about these practices. One way to overcome this skepticism is to strengthen consumer trust through improved supply chain transparency. To create transparency requires a company to both gain visibility into its supply chain and disclose information to consumers. However, the current SR literature has only fo...
