Abstract: Aiming at the efficiency of variant design, module partition was often carried out till the minimum module after establishing the product model. According to the minimum module, Aberrant Point was defined and the BP neural network model for its fast location was established, which solved well the problem of the disorder and inaccuracy in the earlier man-made location method. Finally, a typical case was given to evaluate the performance of the proposed approach, which demonstrated that the approach was obviously helpful for quick of design variant product.
