Chapter 1 System Introduction
1.1 Overview
The state of China’s tobacco industry that is highly dependent on the domestic market has not changed for a long time. With the accelerated pace of WTO accession, tariff reductions, and the cancellation of the special (foreign) cigarette retail license system, foreign cigarettes have more opportunities in the domestic market. Competitive advantage, the domestic tobacco industry is facing unprecedented competitive pressure.
At present, because the management of domestic enterprises is still relatively extensive, the cost of each link is still high, and the cost of the supply chain link is 2 to 3 times higher than that in developed countries. Whether the tobacco industry can closely connect every company, every partner and even every customer in the supply chain, so as to reduce costs more and capture the market faster, is a hot issue of current information construction. The application of the tobacco enterprise supply chain management system has become another new business hot spot and bright spot in the Chinese tobacco industry, strengthening the core competitiveness of the enterprise, competing against the international tobacco giants, winning a place in the competition, and providing new competitive methods and methods.
At this stage, the problems that have led 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 investment cost is too high
●Unable to realize real-time monitoring and tracking of goods
The application of bar code partially solves the above problems. However, due to the shortcomings of bar code such as low reading and writing efficiency, unchangeable information, and small amount of information, it appears to be inadequate in the application of bulk logistics management.
The market launched the RFID-based radio frequency automatic identification technology, according to the actual situation and demand in the supply chain management, integrated the company’s existing applications and bar code technology, and developed the “RFID Supply Chain Management System”.
This system completely solves the problems in supply chain management, breaks the technical bottleneck restricting the development of the enterprise, improves the degree of intelligent production, warehouse management efficiency, distribution accuracy and throughput, and realizes the tracking and visual management of the whole process. , To help companies reduce operating costs and enhance their core competitiveness.
Supply Chain (Supply Chain) refers to the network formed by manufacturers, suppliers, retailers, etc. through mutual provision of raw materials, parts, products, and services.
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 benefits of each member in the supply chain. Supply chain management runs through the entire process of purchasing, processing, warehousing, distribution, and retail.
1.2 Introduction to key technologies
1.2.1 RFID technology
RFID (Radio Frequency Identification) is a technology that uses radio frequency signals for automatic target identification and two-way data communication.
RFID technology is mature and has a good application foundation. Compared with traditional identification methods, RFID has strong advantages.
●Long-distance reading and writing (1-10 meters)
●Multi-target, recognition in motion (up to 1000/sec)
●Large storage capacity, rewritable (100,000 times)
●Long service life (10 years)
These characteristics makeRFIDThe technology can complete information reading and writing and processing without direct contact, optical visualization, and manual intervention, and the operation is convenient and fast. It can be widely used in production, logistics, transportation, medical treatment, anti-counterfeiting, tracking, equipment management and other fields that need to collect and process data, and it is considered as a future substitute for barcode labels.
A typical RFID system generally consists of RFID tags, readers, and computer systems.
●Tag (Tag): Composed of coupling components and chips, each tag has a unique electronic code, attached to the object to identify the target object;
●Reader: a device that reads and writes tag information, which can be designed as a handheld or fixed type;
●Middleware (Savant): Connect RFID equipment and application system software.
