摘要：We investigate the predictive power of operational performance on future financial distress in the context of the US airline industry. We focus on four areas of operational performance: revenue management, operational efficiency, service quality, and operational complexity. Using quarterly data from 1988 through 2013, we find that airlines that have inferior revenue management, lower aircraft utilization, and higher operational complexity face higher future financial distress. Interestingly, a...

摘要：We study a single-stage, continuous-time inventory model where unit-sized demands arrive according to a renewal process and show that an (s,S) policy is optimal under minimal assumptions on the ordering/procurement and holding/backorder cost functions. To our knowledge, the derivation of almost all existing (s,S)-optimality results for stochastic inventory models assume that the ordering cost is composed of a fixed setup cost and a proportional variable cost; in contrast, our formulation allow...

摘要：In this issue, Cui etal. () show how the quantity and quality of user-generated Facebook data can be used to enhance product forecasts. The intent of this note is to show how another type of user-generated contentcustomer search data, specifically one obtained from Google Trendscan be used to reduce out-of-sample forecast errors. Based on our work with an online retailer, we bolster Cui etal. () result by showing that adding customer search data to time series models improves out-of-sample for...

摘要：We are living in an era in which data is generated in huge volume with high velocity and variety. Big Data and technology are reshaping our life and business. Our research inevitably needs to catch up with these changes. In this short essay, we focus on two aspects of supply chain management, namely, demand management and manufacturing. We feel that, while rapidly growing research on these two areas is contributed by scholars in computer science and engineering, the developments made by produc...

摘要：We consider a firm purchasing a storable raw material commodity from a spot market with volatile commodity prices and the access to an associated financial derivatives market. The purchased commodity is processed into an end product with uncertain demand and lost sales. The firm aims to integrate the inventory replenishment and financial hedging decisions to maximize the mean-variance of terminal wealth over a finite horizon. Recognizing time-inconsistency of mean-variance criteria, we employ ...

摘要：We consider an online retailer selling a seasonal product provided by an independent third-party seller who has superior information about the demand potential of the product. The online retailer receives customer orders and then sends the orders to the seller for fulfillment, using pre-installed capacity. The supplier privately installs capacity prior to the selling season. The online retailer faces the challenge to accomplish two goals: to incentivize the seller to install the right level of...

摘要：Buyers can manage product quality sourced from suppliers in three ways: they can improve the quality incoming from suppliers directly by investing in suppliers to improve a process/product, they can improve the incoming quality indirectly by incentivizing supplier quality-improvement efforts, and/or they can control the quality outgoing to subsequent processes by inspecting incoming units. In this study, we study a buyer's use of these three instrumentsinvestment, incentives, and inspectionto ...

摘要：Studying causal effects is central to research in operations management in manufacturing and services, from evaluating prevention procedures, to effects of policies and new operational technologies and practices. The growing availability of micro-level data creates challenges for researchers and decision makers in terms of choosing the right level of data aggregation for inference and decisions. Simpson's paradox describes the case where the direction of a causal effect is reversed in the aggr...

摘要：Manufacturers adopt a variety of channels for the sale of their products in the attempt to deliver the highest possible value to end consumers. For instance, a manufacturers' retail arm provides consumers with the instant gratification of product purchase and the benefit of in-store shopping assistance, whereas their online arm offers potential benefits by selling to market segments that value shopping convenience, product variety, availability, and customization. The main difference between t...

摘要：While the value of using social media information has been established in multiple business contexts, the field of operations and supply chain management have not yet explored the possibilities it offers in improving firms' operational decisions. This study attempts to do that by empirically studying whether using publicly available social media information can improve the accuracy of daily sales forecasts.We collaborated with an online apparel retailer to assemble a dataset that combines (1) ...
