A Study on Electric Scooters for the Elderly by Applying Fuzzy Theory

This research is based on fuzzy comprehensive evaluation, and lists the fuzzy rule table for designers to control a scooter, in order to affect smoothness in the product design process of electric scooters for the elderly. Step 1: Use questionnaire survey method to understand the factors considered by the designer in designing the electric scooter for the elderly. Step 2: Establish hierarchical analysis and consider the factor weight set in electric scooter design. Step 3: Establish fuzzy hierarchical analysis, and sum up the evaluation result set, as based on the designer's experience. Step 4: Comprehensively consider the influence of all factors and obtain the judgment result. Step 5: List fuzzy rules as an application method to improve the traditional design of electric scooters for the elderly. This study found that the travel speed showed the greatest influence 24.98% on the set of factors affecting smoothness.
