Automatic design apparatus, automatic design method and automatic design program for automatically designing design architecture of system components

摘要

An automatic designing system includes: a rule storage unit storing sets of rewrite rules for rewriting variable nodes of a hierarchically structured graph in a design architecture for the system; a search unit sequentially determining variable nodes as application targets for the rewrite rules by searching the graph, including components in the design architecture for the system to be designed, using a search tree; a judgment unit judging whether the rewrite rule is applicable to the determined variable node; and a rule application unit replacing the determined variable node with a partial graph, including at least one of fixed and variable nodes, according to the rewrite rule, in response to a judgment that the rewrite rule is applicable. The search unit performs the searching until an undefined variable node no longer exists in the graph to be designed, and performs backtracking on condition that no variable node is found.
