Abstrakt: Computer-based decision support systems for designers are considered. The nature of system design is discussed in terms of alternative philosophies, processes and methods. The design task is characterized as a form of problem solving which leads to discussion of types of design problem and designer/problem-solver as well as training of designers/problem-solvers. This general background serves as a basis for analyzing information requirements for design. The value of information is defined as having three attributes: (1) reduction of uncertainty, (2) task relevance and (3) appropriateness of form. These attributes, in conjunction with characterizations of stages/tasks of design and approaches to stages/tasks, are used to determine information requirements and the consequent nature of information seeking. The results of this requirements analysis are employed as a basis for consideration of computer-aided information seeking. Types of information/aiding discussed include: facts, fantasies and feedback, as well as adaptive aiding and training, all of which are espoused as the key elements of flexible systems for computer-aided design and computer-aided engineering [ABSTRACT FROM AUTHOR]
