摘要：Cloud computing has been a rising trend in the business world. In this study, we consider two most important pricing schemes offered to sustained customers by major service providers in the cloud industry: the reservation-based scheme (the R-scheme) by Amazon or Microsoft, and the utilization-based scheme (the U-scheme) by Google. We consider a duopoly model with heterogeneous customers characterized by the mean and the coefficient of variation of their usage. We show that under either pricing...

摘要：We consider an M/M/1 queueing system with a pay-for-priority option, and study customers' joint decisions between joining/balking and pay-for-priority. The equilibrium strategies are thus two-dimensional. First, we fully characterize the equilibrium structure and identify the Pareto-dominant strategies of such a game analytically, under both the observable and unobservable settings. Interestingly, the equilibrium structure, the system throughput, and the service provider's optimal price for pr...

摘要：We study a supply chain of a manufacturer selling to two asymmetric retailers engaged in inventory (order quantity) competition in the presence of demand uncertainty and an exogenously given retail price. The effective demand of each retailer includes its primary demand and reallocated demand from its competitor. We model two salient features causing asymmetry: (i) the weak retailer is capital-constrained and (ii) the bargaining power of the dominant retailer implies that it enjoys a lower who...

摘要：We consider call centers that have multiple (potentially inter-dependent) demand arrival streams. Workforce management of such labor intensive service systems starts with forecasting future arrival demand. We investigate the question of whether and when to jointly forecast future arrivals of the multiple streams. We first develop a general statistical model to simultaneously forecast multi-stream arrival rates. The model takes into account three types of inter-stream dependence. We then show w...

摘要：The field of behavioral operations has produced a rich tradition of experiments in newsvendor decision-making. Our study provides a meta-analysis of 24 papers in this research area; we confirm that the pull-to-center (PtC) effect, where average order quantities in a sample lie in between average demand and optimal order quantities, is a very stable observable phenomenon across studies. However, we also show that the asymmetry in the PtC effect between high-margin and low-margin conditions vari...

摘要：Activity network analysis is a widely used tool for managing project risk. Traditionally, this type of analysis is used to evaluate task criticality by assuming linear cause-and-effect phenomena, where the size of a local failure (e.g., task delay) dictates its possible global impact (e.g., project delay). Motivated by the question of whether activity networks are subject to nonlinear cause-and-effect phenomena, a computational framework is developed and applied to real-world project data to e...

摘要：This study presents an analytical framework of the product take back legislation in the context of product reuse. We characterize existing and proposed forms of E-waste legislation and compare their environmental and economic performance. Using stylized models, we analyze an OEM's decision about new and remanufactured product quantity in response to the legislative mechanism. We focus on the 2012 waste electrical and electronic equipment directive in Europe, where the policy makers intended to...

摘要：Using an online experiment, this study examines the efficacy of two idea evaluation processes: scoring vs. ranking in the context of innovation management. In the scoring process, the evaluators are asked to rate the quality of each idea by assigning it a score (e.g., from 0 to 10), while in the ranking process the evaluator simply orders all ideas according to their perceived qualities. Our results suggest that the scoring process strictly outperforms the ranking process in terms of the likel...

摘要：Vacation Timeshare is a form of ownership or right to use of a resort property for a specific time period (typically a week) each year. Timeshare exchange refers to the non-monetary trading of timeshare weeks among owners, so that they can interchange their vacation homes to experience new destinations. The need for member participation during the exchange process has been well-recognized for a variety of practical reasons, including the reluctance of members to accept an authoritarian solutio...

摘要：Conspicuous consumption of status goods signals consumers' status and grants status value to them. In this article, we examine how firms selling status goods make vertical line extension decisions when they take consumers' status preferences into account. Analyzing an incumbent's vertical line extensions when it faces a threat of entry, we find that status preferences can make unprofitable extensions profitable. Moreover, without status preferences, an incumbent can introduce line extensions t...
