TNT express is firstly embodied in two aspects: fast, flexible and convenient. Therefore, express transportation must have fast transportation tools to complete long-distance transportation and small transportation tools responsible for the collection, distribution, and delivery of goods. The transportation tools that meet this requirement are obviously airplanes and various Types of special vehicles. The number of advanced aircraft owned by large express delivery companies that undertake global express delivery is by no means inferior to the number of aircraft owned by world-renowned airlines. Of course, the regional transportation environment of each country and region is different, which also causes companies operating in regions such as Japan or Europe to rely on large freight vehicles to undertake medium and long-distance transportation. In addition, in the distribution centers of goods sources, especially the central areas of the business areas of various companies, express companies must set up dedicated distribution, transfer and control centers, equipped with large warehouses, computer centers, control and command centers, customer service centers, and transportation storage centers And other facilities.
