In this research, we use the theory of problem solving to model
space allocation problems. A formalized system is devised to
solve campus layout planning of elementary schools. By analyzing
the hierarchical structure of campus planning, the system
systematically searches possible solutions using top-down search
strategy.The design method called SAR is used in this research
as a framework to realize the search process. The essential
component of the SAR method consists of two parts, namely, the
support system and the infill. The support system is a spatial
framework, which provides an operational environment for design
process. The infill includes a set of spatial units. The
functional requirements of the layout can be specified as
relationships among the infilling units and the support system.
The entire system can be viewed as a formalized knowledge base
compiled from design experiences, architectural patterns and
domain knowledge. The spatial allocation of campus layout
problems are divided into three levels, which are the campus
level, functional zones and functional spaces. A prototypical
program written with AutoLisp programming language is built to
realize the process of searching for feasible solutions.
Experiments are conducted to evaluate the applicability of the
system.Based on the observation from the experiments, we
concludes that the established hierarchy of the design problem
has great influence to the simplification of the search process.
The applicability of the system depends on how we control the
process and the results by constraints of the support system and
the infilling units.
