摘要：The increasing frequency of traffic accidents involving food delivery drivers has raised public concern about the safety of fast delivery services. In response, food delivery platforms have introduced two corporate social responsibility (CSR) strategies to enhance drivers' road safety: One in which the platform assumes full responsibility for extending delivery times and another that empowers consumers to decide on extended delivery times. Additionally, policymakers are mandating that platform...

摘要：We apply heterogeneous-agent proximal policy optimization (HAPPO), a multi-agent deep reinforcement learning (MADRL) algorithm, to the decentralized multi-echelon inventory management problems in both a serial supply chain and a supply chain network. We also examine whether the upfront-only information-sharing mechanism used in MADRL helps alleviate the bullwhip effect. Our results show that policies constructed by HAPPO achieve lower overall costs than policies constructed by single-agent dee...

摘要：In 2019, self-employed individuals in the United States owned and operated more than 27 million nonemployer firms and generated more than $1.3 trillion in revenue. Our study examines how self-employed workers adjust their operations in response to an exogenous regulatory change that places limits on how they can utilize their productive assets. Extending modern property rights theory of the firm (PRTF), we studied how self-employed for-hire truck drivers modified their operations in response t...

摘要：In this article, we study a shelf-stock allocation problem in a data-driven setting where the demand distribution is unknown. The retailer needs to decide which commodities to place on each level of the shelf (location decision), and determine the stock level for each selected commodity at the shelf (stock decision) that can be adjusted based on updated demand prediction, under constraints on allocation and capacity, so as to maximize total expected profit. Key issues of the problem include de...

摘要：Driven by climate change and overuse, water stress is a worsening sustainability concern that threatens businesses and communities across the globe. Leading global organizations such as the United Nations have expressed an urgent need for sustainable water management strategies across nations and economies. Yet, the field of supply chain management does not have a substantial research stream related to water. A key challenge is the lack of a persuasive organizing framework within this setting....

摘要：The coronavirus disease 2019 (COVID-19) pandemic led to sharp declines in public transit ridership, resulting in budget shortfalls and service cuts that disproportionately affect vulnerable riders who lack alternative transportation options. Understanding the effect of vaccination on public transportation demand is important for planning for demand recovery as vaccination efforts progress. This study examines this effect, with a particular focus on heterogeneous effects across population group...

摘要：In the competitive landscape of modern business, tacit knowledge (TK) sharing has emerged as a critical enabler of innovation and transformation, particularly within the realm of operations management. In this context, the efficient flow of TK is essential for optimizing processes, promoting technology development, and sustaining competitive advantage. While the role of workplace friendship in facilitating TK sharing has been well-documented, there is a common misconception that close personal...

摘要：Order splitting is one of the key issues in the e-commerce order fulfillment process. It increases operational costs, elevates carbon emissions, and compromises customer satisfaction. This article focuses on determining the product assortments to store within the multi-warehouse logistics network to minimize the total number of split orders subject to cardinality constraints. We show that this minimizing split orders (MSO) problem is NP-hard and demonstrate that even finding an optimal order f...

摘要：Spatial unfairness in spatiotemporal forecasting tasks can lead to critical issues, for example, inefficient resource allocation during pandemics or air pollution crises, exacerbating the spread of diseases or increasing exposure to pollution. The existing fair forecasting methods often struggle with spatiotemporal data that lack clear sensitive attributes and exhibit dynamic complexity. A pseudogrouping adversarial machine learning method that combines a spatiotemporal clustering-based pseudo...

摘要：Facilitated by information technology and online platforms, group service has emerged in many service systems, such as one-to-many tour guide service, one-to-many tutoring courses and one-to-many medical diagnosis. We consider a service provider offering both group service and individual service and model it as a single-server queue in which customers with heterogeneous waiting costs make both joining/balking and group/individual service decisions. We solve the private provider's service assor...
