Abstract: According to many kinds of product,it was difficult to get labor time in mass customization environment,the relationship between complexity of new part structure and labor time was researched to obtain the labor hour quickly and accurately,and a labor time estimation method was proposed based on the part complexity.Through analyzing the parts,the key factors affecting part processing time were found out.According to the part topological relations similarity principle and three-dimensional structural model,the computational models of part topology complexity and part process complexity were constructed respectively.Based on the code search principle and the labor time information in database,the functional ration between part complexity and labor hour was confirmed by programming with MATLAB software,which could calculate the processing time of new part quickly and accurately.The proposed method was verified to be feasible by an example.
