Chapter 1 Feasibility of the project

Looking at any country in the world, the development of the military will undoubtedly not rely on information technology as a support point, and develop and grow in combination with itself. Regardless of the military unit, the informatization construction work centered on the development and utilization of information resources has been included in the agenda of army building. The new military revolution centered on information technology is causing profound changes in the military field. The essence of this revolution is the transformation of the mechanized military form of industrial society into the informationized military form of the information society. Along with this historic and dramatic transformation, the informatization of the military has gradually become an important means of accelerating the modernization of the military, and it has also become an important research component of the modernization of the military.

RFID (Radio Frequency Identification) technology is an automatic identification technology that matured from the 1980s. It has its own immeasurable advantages over other identification technologies such as bar code. It stores a large amount of information and stores it. The content can be dynamically changed, the target distance can be read farther, and multiple targets can be identified at the same time. Its automatic and real-time recognition ability is especially suitable for the military management requirements of personnel for vehicles, vehicles and ordnance, and materials.

According to the national army, the most representative use of RFID technology is the US military. The US Department of Defense's application of RFID technology stems from the needs of modern warfare: In the 1991 Gulf War, the United States shipped about 40,000 containers to the Middle East, but due to unclear identification, more than 20,000 containers had to be reopened and registered. , package and re-invest in the transportation system. After the war, more than 8,000 opened containers were not used. Later, the US military estimated that if RFID technology was used to track the whereabouts of logistics and obtain a list of contents of the container, it would save the Ministry of Defense about $2 billion in expenses. After the Gulf War, the US military provided a quick and accurate logistic support for combat troops in solving the serious problems in the process of requesting, transporting, distributing, etc., and proposed an asset visualization management plan to achieve assets in logistics support. Highly transparent. The application of RFID technology makes it possible for the US military to realize the transparency of logistics materials, and provides convenient and flexible solutions for automatically obtaining information on storage, in transit, and materials used for visualization.

RFID technology has been widely used by the US military in the field of military logistics support, such as the specific item search system, the on-the-spot material visualization management system, the individual electronic medical record card, the ordnance armament material storage and management, etc., which has greatly reformed the traditional logistics tracking method. By adopting RFID technology, the average logistics replenishment time of the US military has been greatly shortened.

The information management of armaments and other military materials is precisely the weak link of our army's overall information construction. Most of the warehouse management relies mainly on manual operation, which can't adapt well to the requirements of future war for fast and accurate guarantee. Therefore, fully utilize RFID technology to realize ordnance. The automated management of military materials is the key real element of our military in the field of logistics informationization. It is also the visualization of the whole process of material security in the future, the establishment of a "precise" battlefield material security system, and the realization of the scientific and rapid basis for material security decision-making.

Case: The 2003 Iraq War, saving billions of dollars for the US military

In the 2003 Iraq war, the US-British coalition's visual logistics network built with RFID technology made the US military's logistics supply capacity unprecedented, and the US military could easily grasp the real-time information of all logistics supplies. The British also used this network. , up to 90% of the logistics materials can be efficiently delivered to the front line. This is a far cry from the situation in the 1990 Gulf War.

In this Gulf War, the US military obtained real-time access to logistical supplies in the assembly points of Saudi Arabia, Kuwait, Turkey, the United Arab Emirates, Qatar and Yemen. In combat, the US military's logistics supply line also uses a mobile RFID reader to ensure that the replenishment to the front line can arrive on time, and the use of automatic identification technology to shorten the time in the transfer of materials and inventory, the benefits of logistics replenishment fully use.
