summary A conceptual basis for the development of an expert system which is capable of integrating various modes of generation and evaluation in design is presented. This approach is based upon two sets of reasoning processes in the design system. The first enables a mapping between design requirements and solution descriptions in a generative mode of design; and the second enables a mapping between solution descriptions and performance evaluation in an evaluative and predictive mode. This concept supports a formal framework necessary for a knowledge-based design system to operate in a design partnership relation with the designer. Another fundamental concept in expert systems for design, dual direction interpretation between graphic and textual modes, is presented and elaborated. This encoding of knowledge behind the geometrical representation can be achieved in knowledge- based design systems by the development of a 'semantic interpreter' which supports a dual direction mapping process employing a geometrical knowledge, typological knowledge and evaluative knowledge. An implemented expert system for design, PREDIKT, demonstrates these concepts in the domain of kitchen design. It provides the user with a choice of alternative modes of interaction, such as: a 'design critic' for the evaluation of a design, a 'design generator' for the generation of a design, or a 'design critic-generator' for the completion of partial solutions
