The Determination Method of Product Engineering Features Based on Linguistic Variables

Abstract

To overcome the problem of imprecise and unclear information in the development of quality functions, a method for determining the priority of engineering features based on mixed linguistic variables is proposed. First, the evaluation member uses the determined linguistic variable to give the correlation strength evaluation matrix of customer requirements and engineering features. Secondly, the relative importance of the evaluation member and customer requirements are aggregated. Finally, the priority of engineering features is obtained by calculating the deviation. The feasibility and practicability of this method are proven by taking the design of a new product of a long bag low-pressure pulse dust collector as an example.
