Case 1 When appending part exhibits partial stability with respect to all parts in the existent assembly subset irrespective of the nature of the existent assembly subset. Let us consider part-6 to join an existent partial assembly subset (1-4), part-6 is offered only partial stability with respect to part-1 (S(1,6)=1), which results in partial assembly subset (1-4-6). While appending part-4 to assembly subset (1-2), though existent assembly subset is permanent stable, appending part-4 is offered only partial stability with respect to part-1 (S(1,4)=1) results in partial assembly subset (1-2-4).

Case 2 Even though appending part exhibits permanent stability with respect to all parts in the existent assembly subset, if the existent assembly subset is a partially stable the resulted nature will be partially stable. While appending part-2 to assembly subset (1-4), though appending part-2 is offered permanent stability with respect to part-1 (S(1,2)=3) results in partial assembly subset (1-2-4) due to partial nature of existent assembly subset.

An assembly subset is called as permanent assembly subset, when all the parts in the assembly maintain its respective positions with respect to all mating parts irrespective of orientation. This can be achieved when all the parts in the sub assembly exhibit permanent stability. The permanent stable assembly subset can be formed at two different conditions.

Case 3 When appending part exhibits permanent stability with respect to any of the parts in the existent permanent stable assembly subset. Let us consider part-3 to join an existent permanent assembly subset (1-2), part-3 is offered permanent stability with respect to part-2 (S(2,3)=2), which results in permanent assembly subset (1-2-3).

Case 4 If appending part exhibits permanent stability with respect to any of the parts in the existent partially stable assembly subset as long as the partially stable part motions are completely constrained due to the appending part. While appending part-5 to assembly subset (1-4), though existent assembly subset is partially stable, the appending part bring stability to all the unstable parts and results in permanent stable assembly subset (1-4-5).

Detailed possibilities of stability during subassembly detection is well discussed by considering different possibilities of assembly stabllity instance between pair of parts. The method can be implented for parallel and sequential assembly sequence planning.
