The assembly sequence planning method is presented
where the assembly information model is established with the polychromatic sets
and the assembly constrains relations are divided into three kinds
locating relation
obstructing-disassembly relation
and junction relation
to form an assembly-constrains-relation matrix
and to present assembly planning sequences generation algorithm. Compared with the conventional methods
assembly planning sequence based on polychromatic sets excludes the unreasonable assembly sequences in advance to avoid the exponential explosion due to the expansion of constrain relation.
