Operational Research Application Based on 5G Cold Chain Logistics

At present, as the global economic decreases and the trade friction between China and the United States increases, China must expand domestic demand, increase consumption levels, resolve supply-side structural contradictions, stabilize monetary policy, reduce corporate financing costs, and enhance strategic emerging industries, especially core assets, including the leading enterprises of science and technology, strategic industries, regional assets enterprises, and the strong support from the consumer industry. It also includes the use of exchange rate arbitrage to preserve value and increase employment. Logistics accounts for about 6.43% of GDP [1], among which cold and hot logistics for about 11% [3], and cold chain, a special form of logistics, for 9.7% of tonnage [4]. Cold chain logistics is a complex system engineering, which is closely connected with high-technology and mainly uses full temperature control throughout the whole process. But there are still some shortcomings in China's technology, which causes a lot of material losses every year. This article takes the emerging 5G technology as a carrier, with the help of a strong NB-IoT network, attempts to combine operations research methods to control the new technology of constant temperature control of the layered and block area in cold chain logistics in real-time, and provides some suggestion on participation of all people in BT(Blockchain Technology) and bookkeeping methods.
