The automobile industry is a comprehensive enterprise developed on the basis of many related industries and related technologies. Automobiles use products from many sectors, and various processing technologies are required from rough processing to vehicle assembly. Auto parts include thousands of different parts ranging from floors to screws. The actual automobile production process is completed by a number of different specialized production plants (workshops). In order to manufacture cars economically and efficiently, these professional production plants (workshops) organize production and division of labor according to the principle of product collaboration. Generally speaking, the main assemblies such as engines, transmissions, axles, and body parts are manufactured by the company itself, while tires, glass, electrical appliances, body interior parts and other small parts are mostly produced by outside professional factories through collaboration.
