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...

摘要：Significant evidence has emerged that consumers are boundedly rational and display a sunk cost bias when making decisions. Moreover, customers may display dynamically inconsistent beliefs about the extent to which they will discount sunk costs. We evaluate the impact of sunk cost bias and dynamically inconsistent preferences on commonly used pricing schemes in a service setting with diagnosis and treatment phases. Using a two-part tariff pricing scheme, a monopolist service provider can achiev...

摘要：Online platforms are prone to abuse and manipulations from strategic parties. For example, social media and review websites suffer from sentiment manipulations, manifested in the form of opinion spam and fake reviews. The consequence of such manipulations is the deterioration of information quality as well as loss in consumer welfare. We study one of movie studios' operation activities, sentiment manipulation, in the context of movie tweets. Using the movie release and movie studios' earning a...

摘要：This note complements the study of Burke, Carillo and Vakharia (hereafter referred to as BCV model), which investigates the implications of unreliable supplies on a firm's sourcing decisions under uniformly distributed demand. First, I present a sufficient condition under which the optimal quantity ordered from each supplier corresponds to the solution derived as BCV. Second, a heuristics is developed for the BCV model when the sufficient condition is not satisfied, and conduct numerical exper...

摘要：We investigate the scheduling practices of a multidisciplinary, multistage, outpatient health care program. Patients undergo a series of assessments before being eligible for elective surgery. Such systems often suffer from high rates of attrition and appointment no-shows leading to capacity underutilization and treatment delays. We propose a new scheduling model where the clinic assigns patients to an appointment day but postpones the decision of which assessments patients undergo pending the...

摘要：It is widely accepted that the information technology (IT) industry has high clockspeed. This very phenomenon has led to IT OEMs finding themselves selling new generation models only to be left holding returned merchandise from older generations. Similarly, customers who migrate to newer generations of products experience uncertainty about how to dispose of older but functional IT equipment. Online liquidation markets have emerged to address these needs by finding ways to resell this equipment...

摘要：Virtual power plants (VPP) play a crucial role in balancing the electricity smart grid. VPPs aggregate energy from decentralized sources, for example, biogas, solar panels, or hydropower, to generate and consume electricity on demand. We study the management of electric vehicle (EV) fleets organized in VPPs as a way to address the challenges posed by the inflexible energy supply of renewable sources. In particular, we analyze the potential of parked EVs to absorb electricity from the grid, and...

摘要：We study a dynamic pricing problem, where a firm offers a product to be sold over a fixed time horizon. The firm has a given initial inventory level, but there is uncertainty about the demand for the product in each time period. The objective of the firm is to determine a dynamic pricing strategy that maximizes revenue throughout the entire selling season. We develop a tractable optimization model that directly uses demand data, therefore creating a practical decision tool. We show computation...

摘要：Vaccination is an effective way to prevent an epidemic. It results in immunity for the vaccinated individuals, but it also reduces the infection pressure for unvaccinated people. Thus people may actually escape infection without being vaccinated: the so-called herd effect. We analytically study the relation between the herd effect and the vaccination fraction for the seminal SIR compartmental model, which consists of a set of differential equations describing the time course of an epidemic. We...
