中文摘要：

为了对产品进行有效变型设计,针对产品模型的最小模块,提出了变异点概念,并在分析产品结构的基础上,将反向传播神经网络引入到变型设计中,建立了快速定位变异点的反向传播人工神经网络模型,较好地解决了人为确定变异点的杂乱性与欠准确性问题。最后进行了实证分析,结果表明,采用反向传播人工神经网络快速定位变异点是可行的。

英文摘要：

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.
