An approach to the computer-aided-design of educational facilities through the simulation of educational activities is described in this dissertation. Such a system can be used by school designers to evaluate and improve school floorplans. The implementation of this system involved: (1) the design and implementation of a systematic procedure for determining those characteristics of a school program which affect or are affected by the physical contraints of a school building, (2) incorporation of those characteristics into a model which could be applied by a simulation system to a proposed floorplan, and (3) the development of computer programs which could successfully simulate educational activities on the proposed floorplan and provide feedback to the architect as to the sufficiency of his design.
