摘要：The current literature on the coordination of operations and finance does not differentiate long- and short-term debts and therefore is silent on how firms' debt maturity structure affects their short-run financial and operational decisions. Through a dynamic inventory model that explicitly captures a firm's periodic decisions on inventory replenishment quantity, the amount of dividends net of capital subscriptions, and the amount of short-term debt, we demonstrate that under coordinated short...

摘要：In any pool of ideas that is developed in a multistage process, it is often the case that only a small fraction of top ideas are exceptional. This study formulates a model of multistage development of idea pools, and examines the impact of the structure of idea pools and of learning across stages on the extent to which the top ideas in the pool are exceptional. Our key descriptive results demonstrate that the dispersion of ideas in the pool (defined in terms of the dissimilarity between ideas)...

摘要：The ability to accurately forecast and control inpatient census, and thereby workloads, is a critical and long-standing problem in hospital management. The majority of current literature focuses on optimal scheduling of inpatients, but largely ignores the process of accurate estimation of the trajectory of patients throughout the treatment and recovery process. The result is that current scheduling models are optimizing based on inaccurate input data. We developed a Clustering and Scheduling I...

摘要：For many retailers, markdown decisions are taken by retail buyers whose compensation is based on sales revenue so their objective is to maximize it through the season. This implies that the buyers' objectives are not perfectly aligned with the overall profitability the firm. Many retailers set markdown budgets prior to the season to control margin erosion and increase profitability. Markdown budget constrains the buyers on the amount of discounts that they can apply on a given inventory of mer...

摘要：To be efficient, logistics operations in e-commerce require warehousing and transportation resources to be aligned with sales. Customer orders must be fulfilled with short lead times to ensure high customer satisfaction, and the costly under-utilization of workers must be avoided. To approach this ideal, forecasting order quantities with high accuracy is essential. Many drivers of online sales, including seasonality, special promotions and public holidays, are well known, and they have been fr...

摘要：We consider a firm that procures an input commodity to produce an output commodity to sell to the end retailer. The retailer's demand for the output commodity is negatively correlated with the price of the output commodity. The firm can sell the output commodity to the retailer through a spot, forward or an index-based contract. Input and output commodity prices are also correlated and follow a joint stochastic price process. The firm maximizes shareholder value by jointly determining optimal ...

摘要：Among the various governmental schemes that support agriculture, support prices have been adopted by many developing countries. A support price for an agricultural crop is a guaranteed price at which a governmental entity agrees to purchase that crop from farmers. Despite this surety, a surprising practice of distressed selling has been widely observed in practice: Farmers sell a significant portion of their crops to outside agents at prices much lower than the support price. We build a tracta...

摘要：A cellular bucket brigade is a way to coordinate workers along an aisle with work content on both sides. Each worker in a cellular bucket brigade works on one side of the aisle when he proceeds in one direction, and he works on the other side when he proceeds in the reverse direction. Although the cellular bucket brigade eliminates the unproductive walk-back, it requires more hand-offs to assemble a product than a traditional (serial) bucket brigade. These hand-offs may waste significant produ...

摘要：In project portfolio selection, the aim is to choose projects which are expected to offer most value and satisfy relevant risk and other constraints. In this study, we show that uncertainties about how much value the projects will offer, combined with the fact that only a subset of the proposed projects will be selected, lead to inaccurate risk estimates about the aggregate value provided by the selected project portfolio. In particular, when downside risks are measured in terms of lower perce...
