Thirteen subjects each solved two physical database design problems: five subjects were experienced designers; eight were graduate stude...

For many real-time and distributed decision problems, decision -makers face a wide spectrum of information gathering choices that vary in the amount and quality of information as well as their associated costs and delays. Modeling these problems raises several operational and strategic questions including: how much and what ty...
