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...

摘要:We study the effects of rescheduling on no-show behavior in an outpatient appointment system for both new and follow-up patients. Previous literature has primarily focused on new patients and investigated the role of waiting time on no-show probability. We offer a more nuanced understanding of this costly phenomenon. Using comprehensive clinical data, we demonstrate that for follow-up patients, their no-show probability decreases by 10.9 percentage points if their appointments were rescheduled...

摘要:Problem definition: We study the practice-motivated problem of dynamically procuring a new, short-life-cycle product under demand uncertainty. The firm does not know the demand for the new product but has data on similar products sold in the past, including demand histories and covariate information such as product characteristics. Academic/practical relevance: The dynamic procurement problem has long attracted academic and practitioner interest, and we solve it in an innovative data-driven wa...

摘要:We study a newsvendor problem with profit risk control using value-at-risk (VaR) constraints. When a firm's demand correlates with the price of a tradable financial asset, both financial tools (derivatives) and operational tools (inventory) can be used for profit risk management. Such integrated risk management (IRM) approaches have been studied using various optimization frameworks to reflect the risk aversion of decision-makers. To the best of our knowledge, we are the first to study IRM in ...

摘要:Problem definition: Inspired by new developments in dynamic spectrum access, we study the dynamic pricing of wireless Internet access when demand and capacity (bandwidth) are stochastic. Academic/practical relevance: The demand for wireless Internet access has increased enormously. However, the spectrum available to wireless service providers is limited. The industry has, thus, altered conventional license-based spectrum access policies through unlicensed spectrum operations. The additional sp...
