Backward assembly planning

Abstract

An assembly planning system is presented that operates based on a recursive decomposition of an assembly into subassemblies, and uses design for assembly (DFA) analysis to guide the generation of a preferred assembly plan. The planning in this system incorporates the special processes, such as cleaning, testing, labeling, etc., that must occur during the assembly. The system handles nonreversible as well as reversible assembly tasks through backward assembly planning.<>
