摘要：Problem definition: We investigate the performance of human decision makers selecting which products to offer in a retail category, also known as assortment planning. In theory, this task requires the understanding of product interaction effects, such as cannibalization and inventory pooling benefits, and it involves solving a complex mathematical problem with stochastic and combinatorial components. Despite its practical importance, assortment planning is often performed by managers without a...

摘要：Problem definition: A key challenge in supervised learning is data scarcity, which can cause prediction models to overfit to the training data and perform poorly out of sample. A contemporary approach to combat overfitting is offered by distributionally robust problem formulations that consider all data-generating distributions close to the empirical distribution derived from historical samples, where closeness is determined by the Wasserstein distance. Although such formulations show signific...

摘要：Problem definition: Determining the optimal length of stay (LOS) and posttreatment location is critical for hematology-oncology (blood cancer) patients, who are highly vulnerable to life-threatening infections. Early discharge to home care reduces infection risk, whereas extended hospital observation minimizes mortality risks if an infection occurs. We address this trade-off by developing LOS optimization models tailored to these patients. Methodology/results: We develop a newsvendor-type mode...

摘要：Problem definition: This paper investigates how governments can design optimal public health policies to inform and guide the public amid uncertain health threats. To capture heterogeneity in social behavior, we introduce a class of socializing agents and examine how the government strategically combines two policy instruments-persuasive communication (messages) and physical or monetary penalties-to incentivize compliance with social restrictions. Methodology/results: We develop a game-theoret...

摘要：Problem definition: For e-commerce companies to assess how best to invest in improving delivery times, it is important to understand how improving delivery times affects customer demand. In collaboration with a business-to-business (B2B) e-commerce company, we study how the promised delivery time in a quote affects the customer's purchase probability. Methodology/results: We use observational and experimental data from our partner with quote-level variation in promised delivery times. This all...

摘要：Problem definition: E-commerce giants scale up their order-picking operations by adopting robotic fulfillment centers (RFCs). In RFCs, automated guided vehicles transport movable shelf racks to pickers' workstations, instead of having human pickers travel to pick items. Unfortunately, this apparent relief for pickers turns out to be a curse: Pickers become the bottleneck in the order-picking process. They undertake high-intensity, stationary, and repetitive tasks, which often cause both physic...

摘要：Problem definition: Businesses with short-term production needs can rent equipment (e.g., 3D printer) from a manufacturer or distributor (hereafter, OEM) or use a manufacturing-services firm (e.g., print farm). Those who rent may vary in their expertise and therefore in their cost of attaining quality. Those who use a print farm benefit from the expertise of print-farm technicians. An OEM that offers rentals has an incentive to provide technical service to improve customer expertise so as to m...

摘要：Problem definition: This study examines self-attribution tendencies and their associated outcomes in operations management (OM) performance evaluation in which managers are not always objective when giving credit to outcomes. They may attribute strong performance to internal factors (internal credit), assigning poor performance to external factors (external blame). Methodology/results: Large language models (LLMs) based on LLaMA-3.1-8B-Instruct are fine-tuned to analyze earnings call question-...

摘要：Problem definition: Following recent legislation, private insurers participating in Medicare Advantage (MA) are allowed to expand their set of supplementary services to include benefits that are not primarily health related. This policy is meant to lead to lower costs and better care, but questions have been raised about how this affects the incentives of private insurers. We investigate the implications of the policy for MA offerings, beneficiary enrollment, and social welfare. Methodology/re...

摘要：Problem definition: We study optimal integrated inventory and pricing decisions for substitutable products over a finite planning horizon with full backlogging and nonstationary costs and demands. The objective is to maximize the total expected discounted profit. Methodology/results: We present a unified demand model that encompasses many commonly used models in the literature. We show that the dynamic optimization problem is jointly concave in inventory and market-share vectors. This enables ...
