Abstract: To make the products innovation design process fully consider the demand preferences of customers,a multi-attribute decision-making evaluation method for product innovation design scheme was proposed.The criteria weights determination method was put forward through integrating Kano model and rough set theory based on the analysis of customers'demand preferences,which made the evaluation process reflect the customers'needs effectively and improve the rationality of criteria's weights.By considering the fuzzy and uncertainty of decision information in scheme evaluation,the grey relational analysis evaluation model for multiple-attribute decision-making based on rough number decision-making information processing was established.The optimal product innovation design scheme was selected through incorporating the criteria weights to the analysis model and calculating the difference coefficient of each design scheme.A refrigerator innovation design scheme evaluation example was given to verify the feasibility and effectiveness of proposed method.
