摘要：We consider a periodic review, joint inventory and pricing control problem for a firm that faces general random price-dependent demands. Any unsatisfied demand can be either backordered or lost immediately. The objective is to maximize the expected profit over a finite selling horizon by coordinating the inventory and pricing decisions in each period. For both the backorder model and the lost sales model, we derive some quite general sufficient conditions to ensure the optimality of a base-sto...

摘要：We analyze how salesforce incentives influence a firm's remanufacturing strategy and profitability. We first consider a salesforce incentive model based on the practice of a North American consumer products firm, which offers commissions based on the total revenue generated from new and remanufactured product sales. We then consider a model with differentiated linear commissions for new and remanufactured products. We show that the incentives offered to a salesforce to induce effort can create...

摘要：Many automated manufacturing systems use robotic cells, which consist of a set of machines served by a robot. Robotic cells with a single-gripper robot have been extensively studied in the literature. By contrast, cells with a dual-gripper robot, although more productive, have received less attention, perhaps because of their inherent complexity. We consider the problem of scheduling operations in dual-gripper robotic cells that have the machines configured in a circular layout and that produc...

摘要：The deceased-donor kidney allocation system suffers from a severe shortage of available organs. We illustrate a mechanism which can increase the supply of cadaveric kidneys in the United States. This supply increase exploits the fact that under the current organ allocation policy, some kidneys remain unprocured in some procurement areas but would be highly sought in other areas. The current kidney allocation policy procures within a donor service area (DSA) and offers these kidneys first to pa...

摘要：The prevailing first-come-first-served approach to outpatient appointment scheduling ignores differing urgency levels, leading to unnecessarily long waits for urgent patients. In data from a partner healthcare organization, we found in some departments that urgent patients were inadvertently waiting longer for an appointment than non-urgent patients. This study develops a capacity allocation optimization methodology that reserves appointment slots based on urgency in a complicated, integrated ...

摘要：Hospital readmissions affect hundreds of thousands of patients every year, negatively impacting patients and placing a tremendous burden on the national healthcare system. Post-discharge checkup policies can reduce readmissions through early detection of health conditions, however, the methods behind designing effective checkup policies are poorly understood. Under current practice, up to 67% of readmitted patients return to the hospital before their first scheduled office visit. This work aim...

摘要：Motivated by observations in the greater China region, this paper studies a multinational firm (MNF)'s preferences between two procurement strategies in a global business environment. The MNF relies on a contract manufacturer (CM) to produce its products, which serve both markets within (domestic market) and outside (overseas market) China. The MNF is assumed to be monopolistic in the overseas market but faces competition from a local original equipment manufacturer (OEM) who outsources both m...

摘要：Decision models representing the clinical situations where treatment options entail a significant risk of morbidity or mortality should consider the variations in risk preferences of individuals. In this study, we develop a stochastic modeling framework that optimizes risk-sensitive diagnostic decisions after a mammography exam. For a given patient, our objective is to find the utility maximizing diagnostic decisions where we define the utility over quality-adjusted survival duration. We use r...

摘要：Nursing home managers are increasingly striving to ensure consistency of care, defined as minimizing the number of unique nurse aides who care for a resident during at least one shift over the course of one month. Unfortunately, managers often struggle to provide consistent care, primarily due to last-minute nurse aide absences and choosing to staff these absences with aides from an external rental agency. We are the first to study the use of an on-call pool-aides on staff who may be called in...

摘要：Research in operations management and information systems suggests that information technology (IT) can play an important role in managing operations that support environmentally sustainable (green) growth. Yet, few studies have empirically assessed the efficacy of green IT investments and initiatives, particularly in emerging economies such as India. This study examines the performance consequences of green IT investment and implementation in terms of energy conservation and profit impact. We...
