Application of GPS in Logistics Industry

　　The development of the Internet and the advancement of communication technology, as well as the gradual maturity of cross-platform, componentized GIS (Geographic Information System) and GPS (Global Positioning System) technologies, enable GIS/GPS-based applications to construct a competitive transparent logistics enterprise . According to the survey report of China Warehousing Association, the no-load rate of vehicle operation in my country is about 45%. One of the important reasons for this situation is that logistics companies cannot accurately know the exact location of running vehicles, and they cannot keep in touch with drivers anytime and anywhere, and cannot organize supply sources and flexibly distribute goods for them. At the same time, the driver can only determine the route based on personal experience, and sometimes cannot find the best route, which not only delays the timing but also increases the running cost. In addition, the actual customer cannot keep abreast of the situation of the goods distribution process in time, and cannot coordinate with the logistics company.

　　With the development of the Internet and the advancement of communication technology, the cross-platform, componentized GIS (Geographic Information System) and GPS (Global Positioning System) technologies are gradually becoming mature, and the application based on GIS/GPS will construct a competitive transparent logistics enterprise . The application of GIS to logistics analysis mainly refers to using the powerful geographic data functions of GIS to improve logistics analysis technology. The application of GPS in the field of logistics can monitor the position of moving targets such as vehicles in real time, and issue real-time scheduling instructions to moving targets according to road traffic conditions. The effective combination of GIS, GPS and wireless communication technology, supplemented by vehicle route model, shortest path model, network logistics model, distribution set model and facility positioning model, etc., can establish a powerful logistics information system and make logistics real-time. And the cost is optimal.

　　The advantages of GIS/GPS in the application of logistics enterprises are mainly reflected in the following aspects:

　　1. The application of GIS/GPS will definitely improve the informatization level of logistics enterprises and digitize the daily operations of enterprises, including the logistics equipment owned by enterprises or any piece of goods of customers can be described with accurate numbers, which not only improves the operation efficiency of enterprises, but also improves the operation efficiency of enterprises. At the same time enhance the corporate image, to win more customers.

　　2. The combination of GIS/GPS and wireless communication makes the movement of transport equipment in different places transparent and controllable. Combined with the support of the decision model library of the logistics enterprise, according to the actual warehousing situation of the logistics enterprise, and the real-time road information obtained by GPS, the optimal logistics path can be calculated to guide the transportation equipment, reduce the running time and reduce the running cost. GPS and GIS technology can be used for real-time positioning, tracking, alarming, communication, etc. of vehicles, which can meet the needs of mastering basic vehicle information and remote management of vehicles, effectively avoiding the phenomenon of no-load vehicles, and customers can also use Internet technology, Know the details of your cargo in transit. For example, the vehicle that collects milk in the grassland pasture breaks down on the way. Traditional logistics companies often fail to find the faulty vehicle in time, so that the raw milk of the whole vehicle is damaged and the loss is heavy. And GIS/GPS can easily solve this problem. In addition, the human factor also exists everywhere, and GIS/GPS can effectively monitor the driver's behavior.

　　3. Through the coordination of logistics operations, the development of collaborative business is promoted, and logistics enterprises are transformed to the role of fourth-party logistics. Since the logistics enterprise can obtain the specific location and cargo information of each vehicle in real time, the logistics enterprise can operate the business of the enterprise with the concept of the system and reduce the no-load rate. The transformation of this function, if the logistics enterprise serves a certain supply chain, it can play the role of the fourth party logistics. Logistics enterprises can accurately obtain the information of transportation vehicles through wireless communication and GIS/GPS, and then allow the enterprise and customers to access through the Internet, so as to make the operation and business of the entire enterprise transparent, and lay the foundation for collaborative commerce. The physical structure of the information platform of the logistics enterprise is shown in the figure. However, the integration of geographic information system (GIS), satellite positioning system (GPS), wireless communication (WAP) and Internet technology (Web) in the field of logistics and supply chain management information technology has not been fully matured in China. However, I believe that with people's attention and technological progress, GIS, GPS, WAP and Web technologies will be combined to jointly describe transparent logistics enterprises, reduce logistics black holes, and enhance the competitiveness of domestic logistics enterprises. Stand on your feet.
