Abstract: The aim of this study is to explore the use of automated guided vehicle (AGV) in automotive manufacturing to enable flexible manufacturing to adapt to market changes and consumer demand. Through observation and analysis of the SAIC Volkswagen production line, it is found that the company successfully produced new energy and other platform models on the existing fuel vehicle production line under financial and time pressure. To enable free switching of positioning fixtures between different platforms, heavy-duty AGV are used to carry positioning fixtures for various models on their backs and to switch fixtures freely inside and outside the bodywork line. The research methodology consists mainly of observing, analysing and comparing the advantages and disadvantages of different manufacturing strategies. The results show that the use of a flexible manufacturing planning concept enables the free switching of positioning fixtures for different platforms with minimal investment, the most compact footprint and the least amount of production line modification, thus satisfying the integration of various shapes and various platform models. This study has validated the effectiveness and feasibility of flexible manufacturing using AGV in the automotive manufacturing sector. This finding provides new ideas and methods for the automotive manufacturing industry to respond to market changes and consumer demands, and helps to improve production efficiency and reduce manufacturing costs.
