摘要:We provide an exact myopic analysis for an N-stage serial inventory system with batch ordering, linear ordering costs, and nonstationary demands under a finite planning horizon. We characterize the optimality conditions of the myopic nested batching newsvendor (NBN) policy and the myopic independent batching newsvendor (IBN) policy, which is a single-stage approximation. We show that echelon reorder levels under the NBN policy are upper bounds of the counterparts under both the optimal policy ...

摘要:In scheduling medical residents, the objective is often to maximize resident satisfaction across the space of feasible schedules, relative to the many hard constraints that ensure appropriate patient coverage, adequate training opportunities, etc. A common metric of resident satisfaction is the number of time-off requests that are granted. Simply maximizing this total, however, may lead to undesirable schedules since some requests have higher priority than others. For example, it might be bett...

摘要:Due to yields of less than 50% during the production of curved glass for the displays on their new cell phone series, Samsung has to deal with higher than expected production costs of several million dollars. Where there is random yield, production costs as well as holding costs can be reduced by introducing quality inspections, in which defective items are discarded before further production. To achieve the greatest cost savings, it is important to determine the optimal number and positions o...

摘要:In this article, we look at research published over a five-year time span in the economics of information systems (IS) area in four premier journals, including Management Science, Information Systems Research, MIS Quarterly, and Production and Operations Management, to identify research themes that have implications for future research in the area of Management of Technology (MOT). Through our examination of the literature, we identify three emergent themes that can be used to form foundations...

摘要:Gray markets are created by unauthorized retailers selling manufacturer's branded products. Similar to international gray markets, domestic gray markets are a growing phenomenon whose impact on supply chains is not clear. We consider a supply chain with one manufacturer and several authorized retailers who face a newsvendor problem and a domestic gray market. While a gray market provides an opportunity for retailers to clear their excess inventory (inventory-correction effect), it also can be ...

摘要:In practice, deterministic, multi-period lot-sizing models are implemented in rolling schedules since this allows the revision of decisions beyond the frozen horizon. Thus, rolling schedules are able to take realizations and updated forecasts of uncertain data (e.g., customer demands) into account. Furthermore, it is common to hold safety stocks to ensure given service levels (e.g., fill rate). As we will show, this approach, implemented in rolling schedules, often results in increased setup a...

摘要:This study explores how suppliers adjust their relation-specific investments (RSI) in response to the different risk-taking incentives provided by the customer firm to its CEO, during normal and transition periods. We investigate this relation using 17,553 customer-supplier transactions over the 1993-2013 period. We find strong evidence consistent with the risk-taking argument. Specifically, we find that an increase in the risk-taking incentives of customer CEOs leads to a decline in suppliers...

摘要:We consider supplier-facilitated transshipments for achieving supply chain coordination in a single supplier, multi-retailer distribution system with non-cooperative retailers. The previous transshipment literature has focused on coordination through retailer-negotiated transshipments and thus does not consider the supplier's decision-making. In contrast, in this study, we assume the supplier is an active participant in the system and we seek to understand how the supplier can facilitate the i...

摘要:Organizational learning includes processes of creating, retaining and transferring knowledge and has implications for the performance and competitiveness of organizations. Given the knowledge-based view of resources inherent in management of technology (MOT), in this study, we adopt an organizational learning framework that considers knowledge to be embedded in three major components of organizationsmembers, tasks and toolsand the networks formed by crossing them. We present research related t...

摘要:This study investigates the interactions between a manufacturer's information acquisition and quality disclosure strategies in a supply chain setting in which the manufacturer privately knows his product quality but is uncertain about consumer preferences. We argue that the manufacturer should treat his information acquisition and quality disclosure decisions as an integrated process because these decisions can significantly influence a retailer's rational inferences about product quality and ...
