Abstract
Estimating several models of an architecture is heavy work even if the models are not so large. This paper presents a method that a design support system has a searching function using an idea of information processing techniques. The techniques of a generate-and-test, a data flow formulation, and a recursive call are applied to an architectural design procedure. A few stairway are designed by this method and some features of this method are found as follows; (1) The generate-and-test prevents failing to notice restrictions or design conditions. (2) It is easy to re-design and re-estimate the model. As the result the designer can search the best design. (3) The data flow formulation technique is equivalent to a procedure of the architectural design. Then the designer can maintain and manage the support system easily. (4) For the stairway design, which has a part of same design procedures, the idea of the recursive call is useful. The recursive call programming is realized by the technique of the data flow formulation.
