Dynamic Analysis of Customer Demand Based on Intuitionistic Fuzzy Number in Product Planning

To address the fuzziness and variability in determining customer demand importance, a dynamic analysis method based on intuitionistic fuzzy numbers is proposed. First, selected customers use intuitionistic fuzzy numbers to represent the importance of each demand. Then, the preference information is aggregated using customer weights and time period weights through the intuitionistic fuzzy ordered weighted average operator, yielding a dynamic vector of the subjective importance of the demand index. Finally, the feasibility of the proposed method is demonstrated through an application example of a vibrating sorting screen.
