TY - JOUR TI - Prediction of the sewing standard time based on process difficulty coefficient AU - YIBING SHAO AU - XIAOFEN JI AU - MENGLIN ZHENG AU - HAINA SHEN T2 - Industria Textila AB - In garment production, the standard time is a unit widely used for production planning and calculating cost. It is very difficult to prepare manufacturing plans, short term and long-term forecasts, pricing, and other technical and managerial activities in a garment company without true standard time data. Therefore, standard time prediction as the core of standard time quota management is directly related to economic accounting, production schedule control, resource optimization, production cycles shortening, cost control and product quotation. The sewing process can be regarded as the most critical step for the entire garment production, substantially completing the shape of the garment. To achieve fast and accurate sewing process standard time prediction, this paper established the evaluation indicators for sewing process difficulty, obtained the weight of each expert to indicators analysed with analytic hierarchy process, and made group utility function to calculate the difficulty coefficient. The relationship between the sewing processes standard time and the difficulty coefficient was determined to predict the unknown standard time by curve fitting. The effectiveness and usability of this method were verified by examples. The results demonstrated that the proposed method could be a good alternative to existing prediction methods.
