Research on the upward path and index weight of automobile brands based on AHP and CRITIC models

In order to improve the product power of national auto brands,it is particularly important to study the upward path and indicator weights of national auto brands.Based on the analysis of five data source dimensions, this paper firstly uses a two-dimensional hybrid search algorithm of depth and breadth to calculate all paths and modes with product, service, marketing, culture and innovation as factors;then select different weight calculation methods for data sources from different sources;for survey data and there is no correlation between indicators, AHP is used to calculate weights;for data sources online and there is correlation between indicators, CRITIC method is used to calculate Weight;for the data source from the questionnaire survey data and there is correlation between indicators, the AHP+CRITIC method is used to calculate the weight; finally, the future optimization direction of the model is discussed.
