A computer simulation model for allocating facilities and physical space is presented as a means of optimally allocating available educational resources. The model allows the decisionmaker to change specific program allocations, system parameters, and other controllable variables in order to determine the effects, both cost and utility, of these changes on the total educational system. The discussion of the approach is broken into four topic areas: (1) model overview, providing a flowchart of the space simulation model and a narrative of the design; (2) input, generally describing the data base characteristics of the system; (3) processor, describing the technical considerations that have been designed in the system; and (4) output, discussing the final product characteristics of the systems.
