摘要：We consider a periodic-review perishable inventory system with multiple demand classes, each characterized by a different lost-sales cost and the least freshness requirement. Demands of different classes in the same period could be correlated, while demands across periods are independent but not necessarily identical. In each period, the firm jointly makes the decisions regarding demand fulfillment, production/ordering, and disposal. The objective is to minimize the total discounted expected c...

摘要：In recent years, the rapid development of online marketplaces has given rise not only to co-opetitive relationships between sellers but also to information asymmetries between online marketplaces and sellers. This study studies information sharing in an e-commerce setting consisting of an online marketplace, an upstream manufacturer and a reseller, where the online marketplace possesses superior demand information, while the manufacturer and reseller engage in a co-opetitive structure. The res...

摘要：In this study, we study a hybrid RDC-DC serial inventory system where the regional distribution center (RDC) replenishes its stock from an outside supplier (OS), while the distribution center (DC) faces random demand and replenishes its stock from the RDC. Unlike in the traditional serial system, the DC itself can replenish its inventory from outside as well. We firstly derive structural properties for the optimal long-run average cost and the optimal stationary policy by vanishing discount ap...

摘要：We study production planning in a multi-product setting, in which demand for each product depends on multiple financial assets (such as commodities, market indices, etc). In addition to the production quantity decision at the beginning of the planning horizon, there is also a real-time hedging decision throughout the horizon; and we optimize both decisions jointly. With a mean-variance problem formulation, we first derive the optimal hedging strategy, given the production quantities. This lead...

摘要：Important discretionary tasks such as quality improvement, process compliance, and energy efficiency (EE) require constantly focusing the attention of decision-makers. Using a combination of archival data analysis and a field study, we show how nudges in the form of reminders can serve as a simple yet powerful managerial lever to focus attention on such tasks and increase the likelihood that these tasks will be completed. We study the effectiveness of reminders in the context of EE tasks in ma...

摘要：Organizations routinely introduce hitherto-unexplored interventions to improve their supply chains. Consider a principal (e.g., a firm) that implements a seemingly helpful intervention: For any fixed actions of the principal and the agents (e.g., consumers), the principal's payoff is higher in the presence of the intervention than in its absence. While one would expect such well-intentioned interventions to benefit the principal, several papers within the operations management (OM) literature ...

摘要：We present a new crossing number problem, which we refer to as the edge-constrained weighted two-layer crossing number problem (ECW2CN). The ECW2CN arises in layout planning of hose coupling stations at BASF, where the challenge is to find a crossing minimal assignment of tube-connected units to given positions on two opposing layers. This allows the use of robots in an effort to reduce the probability of operational disruptions and to increase human safety. Physical limitations imply maximal ...

摘要：We consider a for-profit cooperative that sets a quality-based payment to its risk-averse farmers in order to incentivize them to invest in quality improvements. The quality of the farmer's harvest is affected by his investments during the growing season. To satisfy both the farmer and the cooperative, the payment must be competitive with the open-market prices. Cooperatives often set payments that mimic the open-market prices; however, this practice fails to incentivize farmers to invest in q...

摘要：To address the food assistance crisis during the Covid pandemic, the United States Department of Agriculture (USDA) launched a multi-billion dollar Farmers to Families Food Box program (Box program) by working with approved suppliers (or distributors) to purchase fresh produce, dairy, and meat directly from farmers and package them into boxes. Recognizing that food banks did not have spare capacity to support the Box program, how should these food boxes be distributed to people who are in need...

摘要：We study a supply chain setup in which a buyer has private end customer demand information that she can share with the supplier. The demand information is relevant to the supplier's capacity decision. We address the question of whether the supplier benefits from installing nonlinear capacity reservation contracts rather than wholesale price contracts. We contribute to the literature by providing the first internally valid comparison of both contracts with human decision makers. We setup an exp...
