Abstract: To realize the estimation of part labor hour rapidly,the relationship between difficulty coefficient of process and labor hour was researched according to uncertainty of labor hour in mass customization environment,and a labor hour estimation method based on difficulty coefficient of process was proposed.The mathematical model based on nine plates of difficulty coefficient of process such as casting and forming was built.In this model,analytic hierarchy progress and group decision theory were introduced to analyze influencing factors of difficulty coefficient of process comprehensively.The correlative function of the process difficulty coefficient and the labor hour was built based on Matlab and inquiring function of database system.By combining with the coding technology,the efficiency of calculating labor hour was improved.The effectiveness and usability of this method was verified by examples and comparative experiments.

Key words: mass customization, group utility function, process difficulty coefficient, labor hour
