摘要：Little is known about the processes that make TQM effective. Why are some quality improvement projects more effective than others? We argue that TQM processes affect the way people create new knowledge, which in turn determines organizational effectiveness. We explore this by studying 62 quality improvement projects undertaken in one factory over a decade. Using a factor analysis we identify three learning constructs that characterize the learning process: scope, conceptual learning, and opera...

摘要：We consider the long-run odds that narcotics users remain abstinent after methadone treatment. A flexible split-hazard specification that allows for individual-level differences in both the long-run probability of eventual relapse and the short-run timing of relapse is developed. The model is applied to a comprehensive data set involving individual drug abuse and treatment histories for over 800 addicts. Our findings indicate (1) that the short-run success of methadone programs does not automa...

摘要：The problem of expanding the capacity of a single facility in telecommunications network planning is addressed. This problem can be formulated as a time-dependent knapsack, when relevant information is assumed to be known. We introduce the use of scenarios to model uncertainty in key data. The problem is formulated within the robust optimization framework and solved exactly in two phases. The first phase consists of a dynamic programming recursion and the second one of a shortest path procedur...

摘要：This paper describes a framework for the coordination and integration of information systems. By modeling typical enterprise information systems as consisting of multiple agents with different functionalities, the methodology provides the representational formalism, coordination mechanisms, and control schemes necessary for integrating heterogeneous units of an information system while meeting such performance criteria as overall effectiveness, efficiency, responsiveness, and robustness. The f...

摘要：Bid-prices are becoming an increasingly popular method for controlling the sale of inventory in revenue management applications. In this form of control, threshold-or bid-prices are set for the resources or units of inventory (seats on flight legs, hotel rooms on specific dates, etc.) and a product (a seat in a fare class on an itinerary or room for a sequence of dates) is sold only if the offered fare exceeds the sum of the threshold prices of all the resources needed to supply the product. T...
