1. Project background
As we all know, China is the world’s largest clothing consumer and producer. With the rapid development of China’s economy and its high degree of integration with the international market, the improvement of people’s lives and the strong support of government policies, based on the development of rfid technology, the clothing industry has Ushered in the second spring.
Only perfect productivity will have defects. The clothing industry itself has many characteristics, namely: seasonality, regional differences, market changes, product types, etc. The dilemma faced by enterprises is that the management system is not perfect. intense market competition.
The clothing industry also has its special industry characteristics, namely: product style, color, size and other characteristics determine the geometric growth trend of the number of clothing with the increase in styles. The sales system covers various industries such as direct sales, wholesale, and franchising. The clothing industry has encountered bottlenecks in its future development due to its own limitations and the limitations of the industry.
With the development of rfid technology, more companies now begin to pay attention to rfid technology solutions.
Second, the system architecture
(1) Information management of clothing system
With advanced science and technology, Ziyue Technology uses modern information construction to form a series of information management models from factory warehouses to chain stores.
(2) Powerful background data processing software
Real-time understanding of the sales data of each store, query the shortage of products in the store, unsalable products, and ordering status, so that the production plan can be revised in real time, and the unsold products of each store can be quickly allocated.
(3) Powerful handheld inspection system
Three, program steps
(1) Warehouse management
Due to the feature of RFID technology that can identify multiple tags at the same time under non-contact and non-visual conditions, that is, dozens of full boxes of clothing with electronic tags can be accurately read all of their logistics data at one time through an RFID reader , Which greatly improves logistics efficiency. If RFID technology is used to realize the warehousing management, the warehousing management of the logistics distribution center, and the warehousing management of the retail store, the entire supply chain of “shop replenishment demand—distribution center—manufacturer” can be realized. Optimal management of the process.
The use of RFID technology in warehouse management can realize the visual management of all management units, which can greatly shorten the packaging, handling, inventory, and statistics time, thereby reducing cargo damage, accelerating capital turnover, and greatly improving the efficiency of warehouse management. Through this process, 15,000 pieces of clothing items can be verified per hour in only one RFID channel. The automation of the verification process can reduce the time a single product spends in the supply chain by 5 to 7 days.
(2) Logistics management
The benefits of RFID technology in clothing logistics are reflected in the efficiency of logistics management, logistics costs, and delivery control. The application of RFID technology realizes the standardization of clothing logistics operations, shortens operating procedures and operating time, reduces labor costs, thereby reducing operating costs, increasing the throughput of logistics links, increasing the transparency of supply chain management, and improving logistics management efficiency. At the same time, the use of RFID can minimize the delivery error rate. Delivery errors mainly refer to the shortage of original boxes and packing box errors. Both of these problems can be minimized by using RFID technology.
(3) Warehouse management
When garments are produced from the factory and go through the storage procedures, the staff put the goods on a forklift and send them to the back-end warehouse. If possible, a reader and antenna can be installed on each forklift to identify the RFID tag data. When the forklift brings the goods to the warehouse, it is read by the reader at the door of the warehouse and the tag information is sent to the warehouse The management system records the detailed information of the goods received. In the warehouse, goods are placed on containers according to their type, such as style or brand. Bar codes are affixed to the shelves for easy identification. In daily life, employees use RFID devices to read cargo labels and shelf barcodes, and associate the goods with the stored shelves. The handsets are embedded with barcode scanners, and the containers use barcodes instead of RFID tags to avoid obtaining them at the same time. The ID numbers of several containers.
(4) Outbound management
Before being treated as RFID technology, the clothing delivery process was handled manually. That is to say, when these garments arrive at the distribution center from the manufacturer, the staff must manually check them one by one, and when the garments are sent to the clothing store, they must be packaged one by one and recorded manually, which results in many errors. After using the RFID application, the manufacturer’s label is affixed to the clothing item to be sent and verified before delivery, and then an advance shipment notice is issued to the retailer. After the packaged clothing arrives at the distribution center, it will be placed on the conveyor belt. During the transmission process, these labeled packaged clothing will be read by the channel RFID reader. The data after reading is sent to the system, and the software will confirm the ID information. In the event of an incorrect or missing system, a warning will be issued to remind employees to check the clothing goods in the box. After the clothing is repackaged, it is shipped to the clothing store. Before being loaded on the truck, the staff will read the ID number on the tag in the RFID channel according to the packing list, and finally send the advance shipping notice to the clothing store.
(1) Warehouse receipt, delivery, and inventory work: The most important task in warehouse management is to ensure that the booked quantity is consistent with the actual quantity. The use of electronic tags can easily achieve the accuracy of the receipt record and delivery of goods. The automation of distribution prevents omissions and losses in inventory.
(2) First-in, first-out: Each product has a lifespan. Due to the many types of products, it is difficult to ensure accurate first-in, first-out products through manual records and custodian records in actual warehouse management. Through the single tracking technology, a clock can be built in for each product, and the intact state of each product can also be recorded, so that the goods can be shipped out of the warehouse within the specified time limit.
(3) Out-of-stock alarm: When there is a shortage of a certain product in any warehouse, not only can the alarm be automatically prompted, but also the details of product composition such as model type, color, and size can be subdivided. That is, if a certain size of a certain style is broken, the custodian can immediately be reminded to replenish the goods in time.
(4)Statistics of unsalable goods: The backlog of products in the clothing industry is a very headache. Through unsalable goods statistics, the stay time of each product (subdivided into model, color, size) can be quickly discovered. Products that are unsalable and out of season can easily provide price reduction decisions or exchanges to accelerate product sales and capital turnover.
