Research on product modular manufacturing time formulation method under mass customization environment

As the product manufacturing time could not be obtained quickly and accurately under the mass customization environment,this paper explored how to calculate the manufacturing time of customized products.Firstly,according to the modular theory,this paper divided the manufacturing time into the characteristic time module(physical time module,logical time module) and the sub characteristic time module(operating time module,custom time module).Then,it used the CBR technology to determine the quota of operating time and analyzed mechanism which custom factors influenced the manufacturing time,and built separately the quota model of custom time module and mathematical model of product manufacturing time.At last,the practical application of the transformer(G) in a company verified the effectiveness of this method.
