Product Development and Customization

This paper describes a procedure for the selection of the subassemblies and the assembly sequences of a product, applied in an assembly planning software system named FLAPS (Flexible Assembly Planning System), under development at the institute of mechanical technology of the University of Pisa. This procedure is based on a mathematical model of the product, obtained through the definition of 3 matrices: the interference matrix, the contact matrix and the connection matrix. The possible subassemblies are automatically detected by satisfying some mathematical conditions applicable to these matrices. For each subassembly and for the whole product, all the possible assembly sequences are generated, whose number can be successively reduced according to some optimization criteria. At the end, a meaningful example is reported to show the possibilities of the method.
