  • This paper represents a study on disassembly sequence generation system for automobile parts. This system is practically very useful because proper disassembly sequence of end-of-life product becomes crucial as take-back obligations are imposed for environmental reasons. Therefore a disassembly sequence generation system is suggested to automatically derive all the feasible disassembly sequences from the assembly modeling files. As a result, in consideration of the all parts and subassemblies the optimum disassembly sequence is generated. And the optimum disassembly sequence for a certain part or subassembly can be also suggested.

  • Many industrial products can be assembled in various sequences of assembly operations. To save time and cost in assembly process and to increase the quality of products, it is very important to choose an optimal assembly sequence. In this paper, we propose a methodology that generates an optimal assembly sequence by using the knowledge of experts. First, a product is divided into several sub-assemblies. Next, the disassembly sequences of sub-assembly are generated using disassembly rules and special information can be extracted through the disassembly process. By combining every assembly sequence of sub-assemblies, we can generate all the possible assembly sequences of a product. Finally, the expert system evaluates all the possible assembly sequences and finds an optimal assembly sequence. It can be achieved under consideration of the parameters such as assembly operation, tool change, safety of part. basepart location, setup change, distance, and orientation. The developed system is applied to UBR(Unit Bath Room) example.

  • This paper represents a study on disassembly sequence generation for automobile parts. This is particularly useful because adequate end-of-life disassembly becomes crucial as take-back obligations are imposed for environmental reasons. Therefore in this paper a method is suggested to automatically derive all the feasible subassemblies and feasible actions between them from the assembly modeling files. As a result, in consideration of the all pars and subassemblies the optimum disassembly sequence is generated. And the optimum disassembly sequence for a certain part or subassembly can be also generated.
