Abstract
A computer system for the conceptual design of bridges is described. The system uses a restructured version of the Knowledge Base (KB) used in the authors' previous papers and incorporates a new, highly flexible user interface. The restructuring results in a KB which can be easily altered and extended by system users. This is achieved by using a novel form of KB in which the knowledge is fragmented into separate concepts associated with design goals. The style of user-interaction is more strongly associated with Decision Support Systems (DSS) than KBS. This enables the user, rather than the KB, to control the design process. The KB only interacts with the user when it detects a possible error or a more suitable design solution. Even when this occurs, the KB only advises, thus allowing the designer/user fully to implement human capabilities such as common sense. Thus the KB is used to review and assess rather than to impose solutions.
