Abstract: Product design time is an important basic data for product development planning and project management,but with the improvement of product customization degree and development of the trend that customers participate in product design,traditional design time forecasting methods have been unable to meet enterprises'needs.To change this status,the design time forecasting method based on customer collaboration degree in mass customization environment was proposed.The product design process with customers collaborating in mass customization environment was analyzed.The design time prediction principle and the representation mode of customer collaborative degree based on customer collaboration degree,were explained,and the customer collaboration degree coefficient with improved AHP and ordering vector was calculated.Based on enterprise historical data,the relationship function among actual design time,customer collaboration degree and design time obtained from the enterprise's existing model was determined by MATLAB,and thus the design time forecasting model based on customer collaboration degree was established.The proposed method was verified to be applicable and available by an case and comparisons with actual design time and predicted design time through the original business model respectively.Results showed that this method had better practicability and accuracy for design time estimation of mass customization products.
