摘要：Problem definition: Equitable vaccine distribution is paramount to containing global disease outbreaks. An important pathway to achieve this goal is pooled vaccine procurement through global coalitions, exemplified by the COVID-19 Vaccine Global Access (COVAX) initiative, which was implemented based on equitable, centrally managed vaccine allocation, affordable prices, and subsidies to fund lower-income economies. However, the limited participation of high-income countries-which chose to purch...

摘要：Problem definition: Digital content manufacturers and retailers (platforms) frequently encounter the issue of digital piracy. To deter the consumption of pirated content, manufacturers enhance the quality of genuine products, whereas retailers often exert antipiracy efforts. Such efforts best work in coordination, which is achieved through financial incentives via two widely used contracts: wholesale and agency. In the absence of piracy, two results are well established: (a) an increase in the...

摘要：Problem definition: Zoonotic viruses that jump from animals to humans, like avian influenza or severe acute respiratory syndrome, have caused major pandemics in recent decades. Many of these pandemics originated in China, a major supplier and consumer in the global food supply chain, and in other low-and middle-income countries. Interestingly, these outbreaks have been linked to live animal markets, even when the surrounding farms supplying markets had very low infection prevalence. This sugge...

摘要：Problem definition: Emergency medical services (EMS) in many low- and middleincome countries utilize decentralized platforms coordinating independent ambulance providers. However, significant operational challenges arise from uncertainty in provider time availability and unpredictable idle locations. These uncertainties hinder reliable service coverage and negatively impact patient outcomes. Using data from our East-African partner Rescue.co regarding the operations of their emergency platform...

摘要：Problem definition: Faced with the growing need to improve access to care, hospitals have been operating at capacity in recent times. We argue, however, that the pursuit of utilization beyond a threshold might come at a cost. We propose that there exists a zone of efficiency within which the costs of care reach the minimum and the pursuit of utilization outside of this zone may be counterproductive. Our second objective is to explicitly incorporate the complexity of care requirements in unders...

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...

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...

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...

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...
