摘要:This paper examines the impact of two reimbursement schemes, fee-for-service and bundled payment, on the social welfare, the patient revisit rate, and the patient waiting time in a public healthcare system. The two schemes differ on the payment mechanism: under the fee-for-service scheme, the healthcare provider receives the payment each time a patient visits (or revisits) whereas, under the bundled payment scheme, the healthcare provider receives a lump sum payment for the entire episode of c...

摘要:We provide and describe a data set of N = 8; 935 weekly, normalized customer orders over the entire product life cycle for 170 Dell computer products sold in North America over a three and a half year period, from 2013-2016. Total orders for these products exceeded four million units and well over one billion dollars in revenue. While Dell is historically known for fulfilling customer demand with a build-to-order approach, the products in this data set were designated as build-to-stock product...

摘要:Problem definition: We investigate whether firms improve their environmental performance by learning from their own inspection experience and from the inspection experience of other firms. Additionally, we examine how the various facets of inspection experience affect organizational learning. Academic/practical relevance: With the growing awareness that operations can affect the environment, regulators increasingly use facility inspections to assess whether a firm's operations comply with or v...

摘要:This paper seeks an efficient way to screen a population of patients at risk for hepatocellular carcinoma when (1) each patient's disease evolves stochastically and (2) there are limited screening resources shared by the population. Recent medical discoveries have shown that biological information can be learned at each screening to differentiate patients into varying levels of risk for cancer. We investigate how to exploit this knowledge to choose which patients to screen to maximize early-st...

摘要:Problem definition: We study how the government of a developing country optimizes its local content requirement (LCR) policy to maximize social welfare in a setting where foreign original equipment manufacturers (OEMs) produce and sell multicomponent products in the developing country. The foreign OEMs' local sourcing of components is more costly than global sourcing because of technology gaps between local and global suppliers. Academic/practical relevance: We characterize and compare the opt...

摘要:Problem definition: Microretailers in remote rural areas in developing countries face high replenishment costs because of poor road infrastructure and the lack of formal distribution channels. This paper investigates the effectiveness of two innovative replenishment strategies (purchasing cooperatives and nonprofit wholesalers) deployed by nongovernmental organizations to reduce microretailers' replenishment costs and improve consumerwelfare. Academic/practical relevance: The problem is releva...

摘要:The amount of empirical research in operations management that has been published in this journal and in Management Science has recently witnessed a significant increase. Beyond this increase in numbers, research questions and empirical methodologies have also changed substantially. Whereas empirical research in the 1990s was primarily carried out at the firm, plant, or project level, recent research focuses much more on microlevel phenomena. This shift in the unit of analysis has been made po...

摘要:Emergency departments (EDs) typically use a triage system to classify patients into priority levels. However, most triage systems do not specify how exactly to route patients across and within the assigned triage levels. Therefore, decision makers in EDs often have to use their own discretion to route patients. Also, how patient waiting is perceived and accounted for in ED operations is not clearly understood. In this paper, using patient-level ED visit data, we structurally estimate the waiti...

摘要:Problem description: In practice, many consumer products are produced and stocked in product lines rather than in single product variants. The issue is that manufacturers and retailers often do not agree on the product line length (i.e., the number of variants included in the product line). The focus of this study is to understand how product line length and stocking quantities depend on how demand risk is contractually allocated. Academic/practical relevance: Our model combines assortment and...

摘要:Problem definition: Attendance at a museum fluctuates over time and is largely dependent on the exhibitions on display. Schedules can be adjusted to maximize the museum's objectives. Academic/practical relevance: In this paper, we build a model to study and manage the impact of exhibitions on the number of museum visitors. Methodology: We first estimate the model using data collected from two large museums in Barcelona. We then build an optimization framework in which the museum operator can c...
