Technical application scheme of RFID supply chain management system for tobacco enterprises
Chapter 1 System Introduction
§1.1 Overview
The state of China’s tobacco industry’s high dependence on the domestic market has not changed for a long time. With the acceleration of the WTO accession, the reduction of tariffs and the cancellation of the special (foreign) cigarette retail license system, foreign cigarettes have more in the domestic market. Competitive advantage, the domestic tobacco industry is facing unprecedented competitive pressure.
At present, due to the extensive management of domestic enterprises, the cost of each link is still high, and the cost of the supply chain link is 2 to 3 times higher than that of developed countries. Whether the tobacco industry can closely connect every enterprise, every partner and even every customer in the supply chain, so as to reduce costs and capture the market faster, is a hot issue in the current informatization construction. The application of the supply chain management system of tobacco enterprises has become another new business hotspot and bright spot in China’s tobacco industry, providing enterprises with enhanced core competitiveness, competing with international tobacco giants, winning a place in the competition, and providing new means and methods of competition.
At this stage, the problems that lead to the high cost of the supply chain of domestic tobacco companies mainly include the following aspects:
●Many manual intervention, low efficiency and high error rate
●In order to ensure the continuity and accuracy of the information chain, the input cost is too high
●Cannot realize real-time monitoring and tracking of goods
The application of bar codes partially solves the above problems. However, due to the disadvantages of low reading and writing efficiency, unchangeable information, and small amount of information, barcodes are ineffective in the application of bulk logistics management.
Launched on the market based on RFID radio frequency automatic identification technology, according to the actual situation and demand in supply chain management, integrated the existing application and barcode technology of the enterprise, and developed the “RFID Supply Chain Management System”.

Supply Chain (Supply Chain) refers to the network formed by manufacturers, suppliers, retailers, etc. by providing raw materials, parts, products and services to each other.
Supply chain management (Supply Chain Management) is to design, plan and control the information flow, logistics and capital flow in each link of the supply chain, so as to enhance the competitiveness and improve the efficiency and effectiveness of each member in the supply chain. Supply chain management runs through the entire process of procurement, processing, warehousing, distribution, and retail.
