This book closes the gap between information technologies and management decision making. It treats currently relevant topics in information technology_knowledge-based expert systems, graphic-user interface, fuzzy logic, neural networks, data storage, client server, and integration of heterogeneous databases_by using examples and, more importantly, by relating these methods to the needs of the decision maker by taking into account the individual's decision style. The authors provide a solid basis for determining how decision makers use and access information that becomes part of the design of information systems. Integrating the decision maker into the design results in a more intelligent information system because the focus is on the outcome rather than on the methodology or computer power used.
