摘要：Problem definition: This paper explores budget allocation strategies for a multichannel ad campaign, where a marketing agency strives to maximize the total conversions by dynamically adjusting budget allocation over marketing channels. A salient feature of the problem is the interplay of spillover and carryover effects; namely, customers are exposed to ads through multiple channels, and thus ads from one channel affect the effectiveness of the subsequent ads from other channels. Methodology/re...

摘要：Problem definition: We study a dual sourcing problem in an increasingly volatile world. We consider two types of volatilities. External volatilities reflect fluctuating economic conditions via an underlying Markov-modulated state-of-the-world that affects the two suppliers' cost structures, capacity limits, supply mechanisms, and demands. Internal volatilities affect the actual outputs resulting from random supply processes. Demand distributions are impacted by both types of volatilities. Meth...

摘要：Problem definition: Cloud computing is a multibillion-dollar business that draws substantial capital investments from large companies such as Amazon, Microsoft, and Google. Large cloud providers need to accommodate the growing demand for computing resources while avoiding unnecessary overprovisioning of hardware and operational costs. The underlying decision processes are challenging, as they involve long-term hardware and infrastructure investments under future demand uncertainty. In this pap...

摘要：Problem Definition: Proficiency in many sophisticated tasks is attained through experience-based learning, in other words, learning by doing. For example, transplant centers' surgical teams need to practice difficult surgeries to master the skills required. Meanwhile, this experience-based learning may affect other stakeholders, such as patients eligible for transplant surgeries, and require resources, including scarce organs and continual efforts. To ensure that patients have excellent outcom...

摘要：Problem definition: This OM Forum article explores the barriers hindering the implementation of diversity, equity, and inclusion (DEI) programs in supply chains by analyzing the DEI performance of publicly traded and privately held companies. Whereas the importance of DEI in supply chain management is widely acknowledged, publicly traded and privately held companies exhibit a notable gap in achieving DEI goals. Methodology/results: This article explores the factors that enabled publicly traded...

摘要：Problem definition: Large language models (LLMs) are being increasingly leveraged in business and consumer decision-making processes. Because LLMs learn from human data and feedback, which can be biased, determining whether LLMs exhibit human-like behavioral decision biases (e.g., neglect, risk aversion, confirmation bias, etc.) is crucial prior to implementing LLMs into decision-making contexts and workflows. To understand this, we examine 18 common human biases that are important in operatio...

摘要：Problem definition: The rise of digital channels has led to significant media market transformations. This paper studies whether and how digitization, sparked by the launch of Amazon Kindle in late 2007, affected print book sales. Methodology/results: To estimate the impact, we exploit the quasiexperimental variation in the popularity of digital books across different genres or subgenres. We employ difference-in-differences and other identification strategies, and we use print sales data on a ...

摘要：Problem definition: This paper examines frictions in the shopping funnel using empirical clickstream data from an online travel platform. We analyze (a) customers' heterogeneous search and purchase behaviors and (b) their reactions to changes in assortment size. We then develop a consider-then-choose model to generalize our findings. Methodology/results: We characterize the online customer journey as a two-stage consider-thenchoose framework. In the consider stage, we analyze the consideration...

摘要：Problem definition: The joint assortment and pricing problem is notoriously difficult to solve, especially for large-scale issues subject to various operational constraints arising from business practices. In this paper, we delve into the joint optimization challenge under constrained logit choice models, accounting for product-differentiated price sensitivities across static, randomized, and dynamic contexts. Methodology/results: We develop a unified optimization methodology that applies effi...

摘要：Problem definition: We examine how to manage turnover among drivers delivering parcels for last-mile platforms. Although driver attrition in these platforms is both commonplace and costly, there is little understanding of the processes responsible for this phenomenon. Methodology/results: We collaborate with a platform to build a structural model to estimate the effects of key predictors of drivers' decisions to leave or remain at the platform. For this estimation, we apply a dynamic discrete-...
