【Abstract】 The processing of spatial knowledge is involved in the layout design expert system. A topological model of layout.-RECGRAPH is proposed and the corresponding definitions, rules and theorems are discussed. RECGRAPH is an extension of the conventional graph composed of a set of rectangles and a set of edges linking the rectangles. The representations of spatial attributes and spatial relations such as free space, adjacency, position, orientation, view, distance, access are described. Spatial knowledge is represented as shape grammar which, in turn, is represented by RECGRAPH and predicates. The reasoning algorithm for spatial knowledge is given. Two ways of acquiring spatial knowledge ars discussd, and an architecture for layout design expert system is presented.更多还原
