摘要：Problem definition: We consider the joint optimization of ordering and upgrading decisions in a dynamic multiproduct system over a finite horizon of T periods. In each period, multiple types of demand arrive stochastically and can be satisfied either with supply of the same type or by upgrading to a higher-quality product. The goal is to find an optimal joint replenishment and allocation policy that maximizes total expected profit, both when the firm knows the demand distributions a priori and...

摘要：Problem definition: Intense competition in the travel industry has increasingly shifted focus toward ancillary services, particularly seat upgrades in airlines and room upgrades in hotels. In response to this trend, several innovative solutions have emerged, among which Nor1's eStandby Upgrade program stands out by offering discounted, availability-based room upgrades. Revenue management for these upgrades is complex because customers may request multiple upgrades, whereas hotels allocate them...

摘要：Problem definition: Data-driven models in machine learning have enabled efficient management of production systems. However, a majority of machine learning models are devoted to modeling the mean response or average pattern, and this is inappropriate for studying abnormal extreme events that are often of primary interest in aircraft manufacturing. Because extreme events from heavy-tailed distributions give rise to prohibitive expenditures in system management, sophisticated extreme models are ...

摘要：Problem definition: In the aftermath of disasters, governments must make urgent decisions about how to deploy limited resources for recovery, such as restoring roads or siting emergency facilities. However, these actions often need to be taken before the amount and timing of external funding (e.g., federal disaster relief) are known. This mismatch between the need for immediacy and the delay in budget realization poses a fundamental challenge: How can agencies prioritize recovery actions when ...

摘要：Problem definition: We propose a feature-based consideration set choice model (FCM) motivated by customers' purchasing behavior in online retail platforms. In our model, customers form a consideration set by including products with the highest utilities computed based on a subset of product features visible on the search results page. The customers then make a purchase decision from the consideration set by accounting for all features available on the product pages. The FCM incorporates hetero...

摘要：Problem definition: Global supply chains are currently experiencing unprecedented challenges arising from a shift toward deglobalization in international trade policies. This trend has resulted in the tightening of rules of origin (ROOs) within regional trade agreements, placing pressure on firms to localize or nearshore their production activities. In this paper, we explore how firms' global sourcing decisions respond to these changes in trade policies by utilizing the tightening of automotiv...

摘要：Problem definition: For professional products, such as musical instruments and sports gear, a consumer's quality preference is positively associated with the consumer's expertise level. A novice who initially chooses a low-quality product over a high-quality one may have incentive to upgrade if experiencing expertise advancement after professional training. This paper examines a firm's strategies to sell professional products in two periods, training and posttraining, between which consumers' ...

摘要：Problem definition: Fashion retailers are increasingly implementing take-back programs to reduce textile waste and prevent used clothing from being landfilled. To increase participation, retailers must decide how much and what type of information to provide to consumers, how to collect the used clothing, and how much of a financial reward to offer. However, the effectiveness of different types of information, convenience, and reward levels on consumer participation is not well understood, and ...

摘要：Problem definition: A key choice in operational decision making is whether to collocate services. Although prior work has highlighted the benefits of collocation, these benefits may need to be balanced with potential costs. Thus, it is critical to understand not just whether collocation matters, but also when and for whom. We consider collocation in the context of healthcare and ask: Does collocation of mental and physical health resources improve outcomes? This is important, as primary care s...
