Assisted Decision-Making for Assembly Technique Selection and Geometrical Tolerance Allocation
Assembly process planning involves many aspects from geometrical matters to operational research. Though, the literature shows very few works about assembly technique selection.
This paper deals with an original method to select assembly techniques and to allocate component geometrical tolerances in order to minimize the product cost and to maximize the conformity rate associated with the assembly plan.
The data structures used to define a parametric assembly plan is detailed. This data structure is used to formulate a multi-objective optimization problem reflecting the concerns of the study.
The entire method is illustrated trough a case study. The results obtained are presented and followed by a discussion about the potential benefits of its application in an industrial context. The useful support that this method can provide to decision-making is highlighted. Its shared point of view from product designers to manufacturing process designers makes it an efficient tool for concurrent engineering.
