A fundamental study on an exhaustive assembly sequences generation method using the positional relations matrix

Recently, it is important for manufacturing companies to shorten pre-production processes. In the overall process, determination of the optimum assembly sequence is one of the important tasks. However, it is actually selected by some experienced engineers from limited assembly sequences. This paper presents the concept of an exhaustive assembly sequences derivation method based on the positional relations matrix. The exhaustive derivation of the sequences needs to determine all of the intermediate products in the assembling processes. This paper therefore presents an efficient and exhaustive derivation method for intermediate products by disassembling finished or intermediate products. Additionally, the way to list assembly sequences from the intermediate products is shown. The presented method is applied to two products of 13 parts and 24 parts, respectively, and the effectiveness is tested.
