摘要：We consider a continuous-review inventory problem for a retailer who faces random disruptions both internally and externally (from its supplier). We formulate the expected inventory cost at this retailer and analyze the properties of the cost function. In particular, we show that the cost function is quasi-convex and therefore can be efficiently optimized to numerically find the optimal order size from the retailer to the supplier. Computational experiments provide additional insight into the ...

摘要：Managers are increasingly faced with pressure to think not just about profits, but also about their organization's environmental and social performance. This research provides a first examination of operational managers' experiences with and attitudes about employee well-being and environmental issues, how these factors impact employee well-being and environmental performance, and how the three performance measures interrelate. We use violations of Occupational Safety and Health Administration...

摘要：This paper examines the optimal product portfolio positioning for a monopolist firm in a market where consumers exhibit vertical differentiation for product performance and horizontal differentiation for product feature. Our key results are as follows: (i) Variable costs drive vertical differentiation. In the presence of significant volume-dependent manufacturing costs, the optimal portfolio contains a mix of vertically and horizontally differentiated products and an increase in the variable c...

摘要：Designing incentive contracts that constructively guide employee efforts is a particularly difficult challenge in novel innovation initiatives, where unforeseen events may occur. Empirical studies have observed a variety of incentive structures in innovation settings: time and material contracts (compensation for executing orders), downside protection (target-driven incentives with protection from unexpected risks), and upside rewards (additional remuneration for pursuing opportunities). This ...

摘要：We develop variations of the M|G|1 queue to model the process of software maintenance within organizations and use these models to compute the optimal allocation of resources to software maintenance. User requests are assumed to arrive following a Poisson process and a binomial distribution is used to model duplication of requests. We obtain expressions for expected queue lengths with an exponential server using an N-policy for an integer N >= 1. We also obtain the optimal batching size and me...

摘要：This paper introduces a decision model of consumer inertia. Consumers exhibit inertia when they have an inherent bias to delay purchases. Inertia may induce consumers to wait even when it is optimal to buy immediately. We embed our decision model within a dynamic pricing context. There is a firm that sells a fixed capacity over two time periods to an uncertain number of both rational and inertial consumers. We find that consumer inertia has both positive and negative effects on profits: it dec...

摘要：Information delays exist in an inventory system when it takes time to collect, process, validate, and transmit inventory/demand data. A general framework is developed in this paper to describe information flows in an inventory system with information delays. We characterize the sufficient statistics for making optimal decisions. When the ordering cost is linear, the optimality of a state-dependent base-stock policy is established even when information flows are allowed to cross over time. Addi...

摘要：We review, classify, consolidate, and synthesize the contributions to the expanding field of e-business that have been published in Production and Operations Management. We classify e-business research in the following four categories: (1) e-auctions, (2) radio frequency identification, (3) e-business system design, and (4) competition, conflict, collaboration, and coordination (C4 in e-business). We identify important research themes, research methodologies, and research techniques within eac...

摘要：Although white-collar work is of vast importance to the economy, the operations management (OM) literature has focused largely on traditional blue-collar work. In an effort to stimulate more OM research into the design, control, and management of white-collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white-collar work from an operations perspective. Our review classifies research according to its relevance to white-collar w...
