Abstract: Estimating assembly time of configuration product accurately is not only the basis of product sales quotation and delivery time, but also the key to gain a competitive advantage in mass customization environment. This paper analyses the configuration of the company’s existing products with Rough set and defines a time coefficient. Then a regression model on the relationship between the time coefficient and assembly time is built. According to the time coefficient of a new product, its assembly time can be estimated by using this model. In addition, the assembly time of transformers in a company is given to verify the effectiveness of this estimation model, and the error analysis is provided simultaneously.
