摘要：Problem definition: We examine the effects of prolonged consecutive working days without breaks on care quality and explore its association with daily staffing levels in neonatal intensive care nursing teams. Academic/practical relevance: Healthcare organizations typically base staffing guidelines on safe daily metrics like nurse -to -patient ratios. However, in response to unforeseen demand spikes or staff shortages, managers often depend on staff working additional consecutive days to bridge...

摘要：Problem definition: We study the operations of electric vehicles (EVs) providing frequency regulation services to the electric grid in vehicle -to -grid (V2G) systems. In particular, individually owned EVs collaboratively bid in the regulation market, coordinated by a platform that operates the network of charging equipment. We study how the platform determines optimal pricing incentives for drivers to plug in their EVs, accounting for heterogeneous driving schedules. Methodology/results: We m...

摘要：Problem definition: Many logistical and financial challenges of facilitating an election lead election officials to consolidate polling locations. However, determining when it is appropriate to consolidate polling locations and how to consolidate polling locations, if necessary, is a difficult and high -stakes decision that influences voter participation. Methodology/results: We formalize the set of constraints and criteria that election officials should follow as the polling location consolid...

摘要：Problem definition: To improve the welfare of smallholder farmers, multiple countries (e.g., Ethiopia and India) have launched online agri-platforms to transform traditional markets. However, there is still mixed evidence regarding the impact of these platforms and, more generally, how they can be leveraged to enable more efficient agricultural supply chains and markets. This paper describes work conducted in close collaboration with the state government of Karnataka, India, to design, impleme...

摘要：Problem definition: Slotting fees are lump -sum payments retailers demand from manufacturers to include manufacturers' products in their assortments. Although retailers regard slotting fees as part of doing business, some manufacturers claim that slotting fees limit their ability to compete on a level playing field with other manufacturers. Considering these conflicting views, we study the role of manufacturer competition in the emergence of slotting fees and how slotting fees affect retailers...

摘要：Problem definition: We consider a multiportfolio optimization problem in which nonlinear market impact costs result in a strong dependency of one account's performance on the trading activities of the other accounts. Methodology/results: We develop a novel target -oriented model that jointly optimizes the rebalancing trades and the split of market impact costs. The key advantages of our proposed model include the consideration of clients' targets on investment returns and the incorporation of ...

摘要：Problem definition: We study open -shop service networks where customers go through multiple services. We were motivated by a partnering health screening clinic, where customers are routed by a dispatcher and operational performance is measured at two levels: micro -level, via waits for individual services, and macro -level, via overall wait. Both measures reflect customer experience and could support its management. Our analysis revealed that waits were long and increased along the service pr...

摘要：Problem definition: Reducing the likelihood of man-made disasters that cause harm to life, property, and the environment is a key societal goal. To that end, regulatory agencies are responsible for ensuring man-made disasters do not occur. In practice, to accomplish this task, regulators have to rely on and cooperate with operators. However, how much cooperation is optimal? In this study, we explore the prudent level of cooperation between operators and regulators to avoid man-made disasters a...

摘要：Problem definition: The rapid expansion of distributed energy resources (DERs) is one of the most significant changes to electricity systems around the world. Examples of DERs include solar panels, electric storage, thermal storage, and combined heat and power plants. Because of the small supply capacities of these DERs, it is impractical for them to participate directly in the wholesale electricity market. We study in this paper the question of how to integrate these DER supplies into the ele...
