摘要
机械产品的成本构成复杂,在其设计阶段进行成本估计十分必要。在使用神经网络进行成本估计的基础上,利用小波分析对网络进行了改进,提高了收敛速度,并给出例子,在Matlab中进行了计算。
The cost constitution of mechanical product is complicated, and it is quite necessary to carry out cost estimation in the stage of design. On the basis of carrying out cost estimation by the use of neural network, utilizing wavelet analysis to carrying out the improvement on the network raised the convergent speed and a calculation was carried out through Matlab on a given example.
