In order to improve the accuracy of the man-hour calculation under the environment of mass customization, a method for determining man-hour based on error correction coefficient is proposed due to the complexity of man-hour influ-ence factors. In this paper, the evaluation system of man-hour influence factors is established. The fuzzy linguistic ques-tionnaire method is used to evaluate the influence factors and the fuzzy comprehensive evaluation of key influence factors is obtained. By using BP neural network method, the mapping relationship between influence factors and error correction coefficient is determined after training network through Matlab. Then the error correction coefficient is obtained and the precise calculation of man-hour is achieved. This method is verified with strong operability and high accuracy by an example.
