Cycle time design model in garment assembly line based on skilled ratio

Aiming at the existing problem of ″ the initial loss″ in garment production,the relationship between garment production cycle time and production day is studied based on the skilled ratio. Based on the related research results and skilled ratio theories,the model between cycle time and production day was established, and through research, analysis and verification on the relevant data in garment production,the function model has been proved scientific and correct,it is that when Y = 1,i. e. on the first day,it can take mass parameters on company production situation as the basis to estimate production cycle time and make production plan; and when 2 ≤ Y ≤ YC,i. e. from second days to the day that production cycle time is stable,it can use the function model to design production cycle time and control progress,in order to reduce ″the initial loss″.
