Due to their huge size and vast market, manufacturers of FMCG products generally adopt an agent distribution model. The large number and wide distribution of dealers makes commodity circulation complex, difficult management, low efficiency and high costs. FMCG production enterprises in my country generally adopt manual management methods, which cannot track and monitor the circulation of products in a timely manner, so it is easy to cause goods to escape. The phenomenon of fleeing goods refers to the vicious marketing behavior of agent dealers or middlemen driven by interests to sell the products they distribute across regions, causing market chaos and seriously affecting the reputation of manufacturers. The interference of fleeing goods undermines the original market price system and reduces the reputation of corporate brands. For consumers, due to market price chaos caused by fleeing goods, they will worry about whether they have bought counterfeit goods and have mistrust of the company's products, which will directly affect product sales. For dealers who have not fled goods, their interests are damaged due to the fleeing goods behavior of other dealers, so they lose confidence in the company's products and are unwilling to distribute any more, which causes further losses to the company. According to Anheuser-Busch InBev Beer Company, their annual economic losses due to illegal goods exceed 2 billion yuan. At present, the method adopted by illegal dealers is mainly to artificially destroy the QR code identification on the outer packaging of the goods, making it impossible for the production company to verify the actual sales area and the source of the goods. If RFID technology is used to track the entire product circulation process, the cost is too high and is not suitable for FMCG products with meager profits. The above problems have long plagued many FMCG companies and have not been effectively solved.
In response to the above situation, this project proposes a new theory and implementation method for multi-dimensional information anti-counterfeiting of commodity packaging, which is used to design a circulation traceability system for FMCG products. The system is based on digital channel coding technology, which maps the original information of the product to the local area of the three-dimensional model of the product's outer packaging through matrix coding and decoding and hides it in the pattern. The implanted information is correlated one by one with the information in the verification system database and adopts multi-dimensional encryption and anti-encryption technology, so that the original information can be effectively restored even if the outer packaging is severely damaged. Combined with modern information and wireless radio frequency communication technology, the original information of products can be verified and tracked remotely, forming an efficient and reliable anti-counterfeiting and logistics management and control system. During the implementation of the project, because the production line is in a complex operating environment of electromechanical equipment, the low-frequency noise generated by electrical equipment affects the information correlation process. For this reason, we proposed an adjustable band-pass filter based on magnetic media and combined it with an application in open spaces. The low-frequency noise suppression method is used to resist low-frequency noise interference (see papers and patents), improving the accuracy of information correlation. In addition, we conducted a special electromagnetic field analysis on the properties of non-uniform or lossy materials on the packaging structure (see paper), which provided a basis for the design of wireless radio frequency verification devices. The innovation points of this project are first anti-interference and anti-destruction (compared with traditional QR codes), second, low cost (compared with RFID technology), and third, simplicity and ease (without requiring large-scale transformation of the production line), effectively solving the problem of low value-added FMCG manufacturers.
The results of this project began to be applied to the No. 4 production line of Anheuser-Busch InBev Beer's Wuhan factory in early 2013, and expanded to 100 production lines in factories in Wuhan, Tangshan, Putian and Foshan by the end of 2014. The traceability and verification system effectively curbed illegal dealers. The behavior of fleeing goods has saved the company a total of about 200 million yuan in direct economic losses. The company plans to apply the traceability system to all factory production lines nationwide by the end of 2015. The results of this project have produced a total of 4 core patented technologies, and 3 SCI papers have been published in international authoritative journals (IEEE Transactions). In addition to producing significant economic benefits and promoting academic progress, the implementation of the project results has also produced significant social benefits by cracking down on illegal dealers 'fleeing behavior and maintaining a normal price system and market order.
