Research on Health Evaluation of New Energy Vehicle Brands Based on AHP-Fuzzy Mathematical Model

The health degree of new energy vehicle brands directly affects the health status and asset value of automotive companies. This article focuses on the health evaluation of ten representative new energy vehicle brands in China, providing a reference direction for the further value-added of Chinese new energy vehicle brands in the international market and achieving the internationalization and modernization development goals of domestic new energy vehicles. Using 754 data from valid questionnaires, and based on relatively complete evaluation criteria, two methods, item by item evaluation and AHP fuzzy mathematical model evaluation, were used to quantitatively and qualitatively evaluate the health status of the top ten new energy vehicle brands. We have constructed an evaluation system consisting of three factor layers of brand awareness, brand association, and brand loyalty, as well as six sub factor layers corresponding to our subordinates. Evaluation results are: Geely, NIO, Xiaopeng, Li Auto, Wuling, Tesla, and BYD belong to the "very healthy" level and are classified as first-class brands; Chery and Changan belong to the "general health" level and are classified as second level brands; Aion belongs to the "unhealthy" level and is classified as a third level brand.
