Design and Evaluation of Intelligent Blood Pressure Instrument for Older Adults Based on AHP and Fuzzy AHP

Abstract

A design evaluation system for intelligent blood pressure instruments was constructed based on the characteristics of the needs of older adults. According to the Analytic Hierarchy Process (AHP), the object hierarchy was divided into 13 design factors by combining qualitative and quantitative methods, and the comprehensive weight was sorted. Three design schemes were obtained according to the comprehensive weight ranking. Secondly, the Fuzzy Analytic Hierarchy Process (FAHP) was adopted to quantify the fuzzy evaluation results of the design schemes and determine the design scheme with the highest evaluation score. The results show that each judgment matrix passed the consistency test, and the excellent evaluation score obtained by the final design scheme was consistent with the user needs model constructed by AHP. The evaluation system verifies the validity, scientificity, and consistency of the user need model constructed by AHP and FAHP. Therefore, the AHP-FAHP based design evaluation system proposed in this paper can objectively and precisely obtain the user’s needs, simplify the design process, improve the design scheme, help enterprises save design costs, and increase product competitiveness.
