摘要：This study introduces a universal Dome appointment rule that can be parameterized through a planning constant for different clinics characterized by the environmental factorsno-shows, walk-ins, number of appointments per session, variability of service times, and cost of doctor's time to patients time. Simulation and nonlinear regression are used to derive an equation to predict the planning constant as a function of the environmental factors. We also introduce an adjustment procedure for appo...

摘要：Whether to invest in process development that can reduce the unit cost and thereby raise future profits or to conserve cash and reduce the likelihood of bankruptcy is a key trade-off faced by many startup firms that have taken on debt. We explore this trade-off by examining the production quantity and cost reducing R&D investment decisions in a two period model wherein a startup firm must make a minimum level of profit at the end of the first period to survive and operate in the second period....

摘要：Some retailers of seasonal products adopt weather-conditional rebate programs to induce early sales and increase profits. In such promotions, customers who buy the product in an advance preselling period are offered rebates if a pre-specified weather condition is realized during the later normal selling season. We investigate the potential benefits of these programs for retailers. We show that the weather-conditional rebate program can increase sales by price discriminating among a customer's ...

摘要：We study the dynamic assignment of cross-trained servers to stations in understaffed lines with finite buffers. Our objective is to maximize the production rate. We identify optimal server assignment policies for systems with three stations, two servers, different flexibility structures, and either deterministic service times and arbitrary buffers or exponential service times and small buffers. We use these policies to develop server assignment heuristics for Markovian systems with larger buff...

摘要：We study the design of extended warranties in a supply chain consisting of a manufacturer and an independent retailer. The manufacturer produces a single product and sells it exclusively through the retailer. The extended warranty can be offered either by the manufacturer or by the retailer. The party offering the extended warranty decides on the terms of the policy in its best interest and incurs the repair costs of product failures. We use game theoretic models to answer the following questi...

摘要：Improvements in information technologies provide new opportunities to control and improve business processes based on real-time performance data. A class of data we call individualized trace data (ITD) identifies the real-time status of individual entities as they move through execution processes, such as an individual product passing through a supply chain or a uniquely identified mortgage application going through an approval process. We develop a mathematical framework which we call the Sta...

摘要：We study a hybrid pushpull production system with a two-stage manufacturing process, which builds and stocks tested components for just-in-time configuration of the final product when a specific customer order is received. The first production stage (fabrication) is a push process where parts are replenished, tested, and assembled into components according to product-level build plans. The component inventory is kept in stock ready for the final assembly of the end products. The second product...

摘要：Coordination efforts that access and align relevant cross-functional expertise are regarded as an essential element of innovation success. In recent years, these efforts have been further augmented through complementary investments in information systems, which provide the technological platforms for information sharing and coordination across functional and organizational boundaries. Somewhat overlooked has been the critical mediating role of the intelligence gained through these efforts and ...

摘要：Supply contracts are used to coordinate the activities of the supply chain partners. In many industries, service level-based supply contracts are commonly used. Under such a contract, a company agrees to achieve a certain service level and to pay a financial penalty if it misses it. The service level used in our study refers to the fraction of a manufacturer's demand filled by the supplier. We analyze two types of service level-based supply contracts that are designed by a manufacturer and off...
