  摘要：Problem definition: Addressing capacity management within a multifaceted network of resources is a critical challenge in service operations management. As resources are often shared to serve multiple classes of customers in such systems, customer routing often depends on the congestion levels of these resources, which in turn are affected by customer routing, creating a feedback loop. Consequently, when evaluating the impact of substantial capacity changes in the network, one must account for ...

  摘要：Problem definition: This paper studies dynamic irrigation management under weather uncertainty and spatial soil heterogeneity of the field. Irrigation is a key method for increasing agricultural yield, addressing growing concerns about food insecurity in recent years. However, managing irrigation effectively is a complex task, particularly under uncertain weather conditions. With rising concerns about freshwater scarcity, increasing production costs, and the impacts of climate change, it is im...
• Managing Quality on Two-Sided Platforms in the Presence of Provider Competition AI翻译

  摘要：Problem definition: We study two-sided markets in which competing platforms enforce service standards to control access of providers with heterogeneous service quality and employ pricing strategies to balance supply and demand. We further investigate the effectiveness of launching regulations, aimed to maximize social welfare, in enhancing quality, and we examine multihoming to yield additional insights. Methodology/results: We build a game-theoretic model wherein two platforms enforce service...
• Inventory Systems with Record Inaccuracy: Transaction Errors vs. Unobservable Loss AI翻译
  作者：Chehrazi, Naveed
  作者单位：Washington University (WUSTL)
  摘要：Problem definition: We present a continuous-time Bayesian model for managing inventory in a retail setting when inventory records are inaccurate. In our formulation, the inventory level and its record have separate dynamics. The former is driven by the demand and unobservable loss process, whereas the latter is driven by the demand and transaction error process. Methodology/results: We analytically characterize the dynamics of the retailer's belief on the shelf inventory level and prove that t...
• Flexibility Value of Reshoring Capacity Under Policy Uncertainty and Domestic Competition AI翻译
  作者：Kouvelis, Panos; Tan, Xiao; Tang, Sammi Y.
  作者单位：Washington University (WUSTL); East China University of Science and Technology; University of Miami
  摘要：Problem definition: Companies operating global supply chains face growing policy uncertainties that affect the costs of importing raw materials (RM) and finished goods (FG) from low-cost to developed countries, as well as the relative profitability of production in different countries. This has prompted the need for diversified global supply chains often involving the addition of onshore production alongside existing offshore facilities. Motivated by recent developments in the U.S. clean energ...
• Product Information Display Optimization with Quality Uncertainty and Returns AI翻译

  摘要：Problem definition: Display quality refers to product information such as the images and textual descriptions of product quality presented to consumers shopping online and can directly influence market demand during the sales phase and returns during the postsales phase. In this paper, we investigate the optimization problem on assortment planning, display quality, and pricing, taking into account the actual quality uncertainty and consumer returns. Methodology/results: We employ the widely us...
• Joint Assortment Optimization and Discrete Marketing Mix Allocation AI翻译
  作者：Li, Shuai; Ye, Zikun; Chen, Xin; Xie, Weijun
  作者单位：University System of Georgia; Georgia Institute of Technology; University of Washington; University of Washington Seattle
  摘要：Problem definition: Assortment selection and marketing mix allocation are critical decisions for retailers, directly influencing consumer choices. In this paper, we propose a multinomial logit (MNL) choice model in which consumer utility is influenced by marketing decisions such as advertising and promotions: a model widely utilized in empirical marketing literature. We then study the joint assortment and marketing mix allocation problem subject to either cardinality constraints or knapsack co...
• On Data-Driven Prescriptive Analytics with Side Information: A Regularized Nadaraya-Watson Approach AI翻译
  作者：Wang, Yijie; Srivastava, Prateek R.; Hanasusanto, Grani A.; Ho, Chin Pang
  作者单位：Tongji University; University of Texas System; University of Texas Austin; University of Illinois System; University of Illinois Urbana-Champaign; City University of Hong Kong
  摘要：Problem definition: Motivated by the significance of side information in numerous operations management problems, this paper studies conditional stochastic optimization to enable more informed decisions. The side information constitutes observable exogenous covariates that alter the conditional probability distribution of the random problem parameters. Decision makers who adapt their decisions according to the observed side information solve a stochastic optimization problem where the objectiv...
• Reducing Traffic Incidents in Meal Deliveries: Penalize the Platform or Its Independent Drivers? AI翻译

  摘要：Problem definition: Some governments have toughened traffic penalties for meal-delivery drivers, yet the number of meal delivery-related traffic incidents has not abated. These observations prompted two questions: Under a given penalty scheme, how should a profit-maximizing platform determine the delivery fee to charge its customers and the commission to pay its drivers? How should a welfare-maximizing government determine its penalty scheme to curb traffic incidents and improve the social sur...
• Strategic Entry of Farmers' Cooperatives in Agricultural Markets AI翻译
  作者：Qian, Xiaoyan; Zhou, Quan; Olsen, Tava Lennon
  作者单位：University of Melbourne; University of Wollongong; University of Melbourne
  摘要：Problem definition: In agricultural markets, farmers often face powerful investor-owned firms (IOFs) that dominate marketing and impose pricing pressure at the farm-gate. To counter this, farmers can form cooperatives (co-ops), which differ from IOFs in their objectives and transaction dynamics, to collectively enter the market. Although co-ops can be established with different membership structures, the impact of their potential market entry remains unclear, as does the question of which co-o...
