| Abstract: | A definite RECGRAPH structure will prescribe certain spatial topological relations in a plane layout. Five theorems about RECGRAPH dimensioning are proposed and proved under the assumption that RECGRAPH structure will remain unchanged. A RECGRAPH dimensioning mechanism for layout design expert system has been developed. The functions of the dimsnsioning mechanism are to analyze the RECGRAPH structure, to intelligently construct the dimension inequalities and to solve the inequalities. The maximum and minimum dimensions of an edge will then be obtained. The forward reasoning strategy is adopted in the dimensioning mechanism which contains a rule base stored with heuristic rules of the way to use the theorems and write out the dimension inequalities. |
