摘要：A mathematical model is presented for studying the effects of interactions among team members on the process of replacing members of a team in an organization. The model provides the ability to control the number of members that interact with each individual on the team. Through the use of analysis and computer simulations, it is shown how the amount of interaction affects the tradeoff between the expected performance and the number of replacements and interviews needed to find a good team usi...

摘要：We analyze the problem faced by companies that rely on TL (Truckload) and LTL (Less than Truckload) carriers for the distribution of products across their supply chain. Our goal is to design simple inventory policies and transportation strategies to satisfy time-varying demands over a finite horizon, while minimizing systemwide cost by taking advantage of quantity discounts in the transportation cost structures. For this purpose, we study the cost effectiveness of restricting the inventory pol...

摘要：A large midwestern hospital is expecting an increase in, surgical caseload: New operating, room (OR) capacity can be had by building new ORs or extending the working hours in the current ORs. The choice among these options is complicated by the fact that patients; surgeons and, surgical staff, and hospital administrators are all important stakeholders in: the health service operation, and each has different priorities. This. paper investigates the trade-offs among three performance criteria (w...

摘要：This paper examines the incentives for firms to share information vertically in a two-level supply chain in which there are an upstream firm (a manufacturer) and many downstream firms (retailers). The retailers are engaged in a Cournot competition and are endowed with some private information. Vertical information sharing has two effects: direct effect due to the changes in strategy by the parties involved in sharing the information and indirect effect (or leakage effect) due to the changes in...

摘要：Over the past fifteen years, a number of studies have examined the determinants of firm R&D spending. These studies, however, almost invariably focus on the role of firm or external ownership characteristics in predicting R&D spending while overlooking the attributes of the top managers involved in allocating corporate resources. In this study, we change that focus by empirically examining how R&D spending as compared to industry competitors varies at firms based on the characteristics of thei...

摘要：Protecting confidential, numerical data in databases from. disclosure is an important issue both for commercial organizations as well as data-gathering and disseminating organizations (such as the Census Bureau). Prior studies have shown that perturbation methods are effective in protecting such confidential data from snoopers. Perturbation methods have to provide legitimate users. with accurate (unbiased) information, and also provide adequate security against disclosure of confidential infor...

摘要：To what extent do firms go abroad to access technology available in other locations? This paper examines whether and when state technical capabilities attract foreign investment in manufacturing from. 1987-1993. We find that on average state R&D intensity does not attract foreign direct investment. Most investing firms are in lower-tech industries and locate in low R&D intensity states, suggesting little interest in state technical capabilities. In contrast, we find that firms in research-inte...

摘要：Column generation is a well-known and widely practiced technique for solving linear programs with too many variables or constraints to include in the initial formulation explicitly. Instead, the required column information is generated at each iteration of the simplex algorithm. This paper shows that, even if the number of variables is low enough for explicit inclusion in the model with the available technology, it may still be more efficient to resort to column generation for some class of pr...

摘要：We analyze a dynamic auction, in which a seller, with C units to sell faces a sequence of buyers separated into T time periods. Each group of buyers has independent, private values for a single unit. Buyers compete directly against each other within a period, as in a traditional auction, and indirectly with buyers in other periods through the opportunity cost of capacity assessed by the seller. The number of buyers in each period, as well as the individual buyers' valuations, are random. The m...

摘要：In contrast to the prevailing supply-side explanation that price decreases are the key driver of a sales takeoff, we argue that outward shifting supply and demand curves lead to market takeoff. Our fundamental idea is that sales in new markets are initially low because the first commercialized forms of new innovations are primitive. Then, as new firms enter, actual and perceived product quality improves (and prices possibly drop), which leads to a takeoff in sales. To provide empirical evidenc...
