摘要：In this paper, we explore the effectiveness of late penalties in reducing patient tardiness. Specifically, we evaluate two types of penalties: the last-place penalty (i.e., assigning late-arriving patients to the end of the queue) and the fixed-place penalty (i.e., moving late patients back by a fixed number of positions), under two conditions-absence of a time recommendation and presence of an explicit time recommendation. We conducted a randomized controlled trial involving 9,573 patient vis...

摘要：This paper investigates the supplier's pricing problem under upfront reservation discount (URD) contracts where the buyer reserves products in advance and then adjusts the purchase quantity based on realized end-market demand. A key challenge is that the supplier typically has limited data to estimate the demand distribution and possesses inferior information compared to the buyer. To address the challenges of distributional ambiguity and information asymmetry, we develop a refined distributio...

摘要：In this article, we consider a multi-stage assortment optimization problem with multinomial logit (MNL) choice modeling under resource knapsack constraints. Given the current resource inventory levels, the retailer makes an assortment decision at each period, and the goal of the retailer is to maximize the total profit from purchases. With the exact optimal dynamic assortment solution being computationally intractable, a practical strategy is to adopt the re-solving technique that periodically...

摘要：Group Purchasing Organizations (GPOs) play a crucial intermediary role in the U.S. healthcare supply chain by consolidating purchasing power across multiple healthcare providers. However, increasing competition from peer organizations and hospitals' insourcing efforts has placed significant pressure on GPOs to enhance their value propositions. This study presents a data-driven framework designed to help GPOs reduce medical supply costs for hospitals by addressing inefficiencies in vendor tier ...

摘要：The rise of generative AI (GenAI) technology is revolutionizing firm operations and supply chain management, profoundly influencing firms within the GenAI supply chain network. While a few emerging studies have explored the impact of GenAI initiatives on firms' stock performance, it remains unclear how such disruptive technology initiatives affect the stock price movements of their supply chain partners. This paper empirically investigates the impact of firms' GenAI initiatives on the abnormal...
