As discussed previously, understanding the product structure is especially important. Putting together of parts becomes sub-assemblies and putting together sub-assemblies becomes final assembly. There are so many paths one can choose to achieve this but the most cost-effective one is what must be found in each case. The optimal plan of assembly significantly influences the product cost.
Here again, the analysis of product structure comes to good use. The levels of sub-assemblies and the parts within the sub-assembly are analyzed thoroughly to decide an optimal assembly sequence. There are many analytical methods available to decide on the optimal assembly path.
When choosing a product assembly following things must be considered
