Description

The design verification is one of the most important problems in constructing an intelligent design support environment. Particularly in machine design, it is important to verify whether the designed machine can be assembled from discrete parts. This paper presents problem formalization for an automatic planning system which produces an assembling sequence of a given machine structure which is described in the design object modeler CONMOTO. The 'sequence is equivalent to the constructive verification whether the designed machine can be assembled. At first several restrictions are introduced and the assembling procedure is inverted to a disassembling procedure. Discretizing the direction and the dis-tance of the part's movement by some heuristics, the disassembling procedure can be acquired by the search-based problem solving method which is so called in the artificial intelligence research field. Finally this paper shows the disassem-bling sequence can be planned efficiently utilizing a “Plan Tree” which is heuristic partial order of assembling. The detail of the planning system is shown in the next report.
