1. Application background
Today, the supply chain has become a key area of competition among enterprises, and the integration and management of the supply chain also means that enterprises will face a series of new technological challenges.
Factors such as intensified market competition and variability in demand urge product production and sales traders to continue to accelerate their pace, introduce personalized and flexibly configurable products, ensure promises, deliver on time, and quickly respond to the changing requirements of customers , Hobbies and the external economic competition environment. In supply chain solutions, speed, efficiency, accuracy, and information integration are the key goals pursued by the program.
Reasonable and efficient supply chain management can capture customer needs and share information in the entire supply chain, enabling companies to accurately predict the possibility of inventory shortages, and timely replenishment to avoid any delays that may result, and to ensure planning from start to finish Synchronize with execution. Through the synergy of the supply chain, companies can reduce the scale of inventory, shorten the return period of investment, improve the quality of products and services, and accelerate the company’s response to the market.
Supply chain refers to the movement process of all physical objects from raw materials to end users. Including supplier selection, purchasing, product planning, material processing, order processing, inventory management, packaging, transportation, warehousing and customer service. Successful supply chain management can seamlessly integrate all partners into the supply chain.
In the supply chain management, the most critical technology is the tracking of goods. At present, the information identification tracking technology commonly used in the supply chain management system is the barcode technology. The barcode technology has various deficiencies, such as reading only one label at a time, and the amount of data is limited. Poor environmental adaptability and the same product with the same bar code limit the improvement of supply chain efficiency.
This solution adopts electronic tag (RFID) technology to better solve these problems.
RFID is a radio frequency data collection technology and the best means of tracking goods. It is superior to barcode recognition technology in that RFID can dynamically identify high-speed moving objects and can simultaneously identify multiple electronic tags. The identification distance is large and it can be adapted Harsh environment. At the same time, because the electronic tag can uniquely identify the goods, it is possible to track the goods in the entire supply chain, and to know where the goods are in the supply chain in real time.
The implementation of the electronic label system solution can achieve the following goals and obtain the expected economic benefits:
1. Shorten the work process
2. Improve the quality of inventory operations
3. Increase the throughput of the distribution center
4. Reduce operating costs
5. Logistics tracking in the supply chain
6. Increase the transparency of supply chain management
7. Capture data on the process
8. The transmission of information is faster, more accurate and safer.
Commodities flow through the entire supply chain. The most frequent operations are outbound/inbound operations and warehouse management.
The following focuses on the application of RFID in outbound/inbound management to comprehensively introduce the electronic label system solution.
2. System introduction
Faced with the work of receiving and warehousing that must be repeated every day, how can we quickly complete the rapid verification and collection of large quantities of goods?
How to quickly find the designated goods in the warehouse? Now most warehouses still distinguish the positions by sticking handwritten cards on the shelves. For these warehouses, this is a time-consuming and laborious task. Moreover, there are often mistakes of picking up the wrong goods and repeated picking up many times.
Does the inventory have to be closed to proceed? The losses caused by the closing of large warehouses are obvious, and enterprises are absolutely unwilling to bear it. However, it is impossible to truly grasp the situation of the warehouse without taking an inventory, which is also something that the managers of the enterprise are unwilling to face. Is there a way to carry out warehouse inventory without affecting the normal work of the enterprise?
Can forklift scheduling be more reasonable? In the entire warehouse operation, forklift resources are relatively scarce. How to make full use of it is a key to improving the efficiency of the entire warehouse. To make full use of forklifts, forklifts must be dispatched through the management system so that they are always at full capacity on the most efficient line.
A reasonable RFID application system will find a good solution to these problems.
(1) Packing and labeling system
Before the goods are put into storage, set up the packing area (this step can also be completed on the product production line).
According to the actual warehouse management application requirements, the corresponding single products are packed into independent packages according to the specified quantity, the operation information is written into the label, and the label and the box are hung or pasted.
(2) Inbound and outbound inspection system
1. System composition:
Access RFIDStation: fixed reader/antenna, sensor system, process controller, indicator light, alarm, indicator panel (indicating receipt and delivery information, loading information, etc.)
Label selection and installation: pallet label RPC, box label (adhesive type)
2. The benefits of RFID to warehouse management
(1) The management personnel can grasp the status of inventory materials in real time, so as to realize the information transparent asset management method
(2) There is no need to implement traditional inventory work, thereby reducing the backlog of materials, speeding up capital turnover, and facilitating production guidance
(3) Solve the traditional management mode that is prone to human errors and untimely information exchange in manual statistics
(4) Reduce the workload of manual statistics and improve work efficiency
(5) Prevent the occurrence of misconduct by technical means
If the warehouses of the enterprise and the warehouses of each branch are equipped with long-distance radio frequency identification equipment, and realize the network connection in the system, so that it has automatic passage identification, real-time entry and exit records, authorized passage, illegal entry and exit alarm, information query, data analysis, etc. A variety of functions.
It will play a positive role in real-time, accurate and complete control of material flow and improvement of scientific management efficiency. The implementation of long-distance radio frequency identification technology will help to assist the logistics system to achieve reliable security. It has become a powerful partner in enterprise information management, and will better realize the unity of “effective supervision” and “increasing efficiency.”
(3) Forklift stacking and picking system
1. System composition
Forklift stacking and picking RFIDStation: On-board terminal (WLAN), Reader/antenna,
Label selection and installation: pallet label RPC2, typical application process
Forklift stacking and picking systems are usually applied to pallets and large containers, and the reader/antenna is connected to an industrial-grade vehicle-mounted terminal (built-in WLAN).
3. Application revenue
It can automatically target pallet stacking and picking, improving pallet cargo handling, planning, and forecasting capabilities.
(4) Inventory
The staff uses a handheld terminal to read the data in the pallet label. The pallet label records the actual number of goods carried by the pallet. Real-time data transmission can be realized through the wireless network, or the data can be collected in batches after half a day. The processing method is transferred to the background management system. Therefore, through the automatic collection method of RFID technology, fully automatic real-time and partitioned inventory without manual intervention can be realized, and the rapid progress of inventory operations and the accuracy of inventory data can be ensured.
(5) RFID system application
Although the application of each management link of the supply chain is diverse, the application of RFID technology can be summarized into several abstract processes. That is: for different packaging levels (single product, packaging box, pallet), solve such as conveyor belt item sorting identification, inbound and outbound product receipt and delivery identification, product information collection during the packaging process; collection during forklift operation, and mobile data Collection and other processes. For each process facing different packaging levels, companies have different profit profiles.
(6) RFID investment income model
(7) Issues considered in the implementation of RFID projects
Successful application cases of RFID technology in the logistics supply chain
RFID (Radio Frequency Identification) inventory tracking system refers to the automatic storage and transmission of information such as component specifications and serial numbers by attaching RFID tags to pallets, boxes or components. RFID tags can transmit information to radio frequency readers within 10 feet, so that warehouses and workshops no longer need to use handheld barcode readers to scan barcodes one by one for components and products in progress, which reduces omissions to a certain extent Occurred, and greatly improved work efficiency. The application of RFID can significantly cut costs and clear up obstacles in the supply chain.
This technology is closely linked to the logistics supply chain and is expected to replace barcode scanning technology in the next few years.
Market orientation and trends
Due to Wal-Mart’s vigorous advocacy and requirements for suppliers to adopt radio frequency identification (RFID) technology before 2006, many application system developers have upgraded their programs. Sun, SAP, Oracle, IBM, HP, MICROSOFT, etc. have also begun to be mainstream in the company Integrated radio frequency identification (RFID) technology in the product.
Wal-Mart recently stated that it will no longer purchase products from suppliers that do not use RFID technology in the future, which greatly shakes the application industry. Wal-Mart’s decision affects RFID applications throughout the world, such as Oracle’s database and application server and SAP’s R3 system. Sun has decided to integrate RFID into the SunOne integration platform. IBM’s DB2 will also send data from RFID readers. Into the enterprise-level application system.
At present, the identification of retail products is realized by barcodes. When the products are sold, they are identified by a barcode reader. The barcode data is only identified once in the entire circulation process. On the other hand, RFID does not need to manually identify the tag, the reader can read the location and product-related data from the radio frequency tag every 250 milliseconds. Some readers can read data of 600 tags per second, which is more than 1,000 times faster than traditional scanning methods.
