Application of RFID in logistics management of lar

  • Detail

The application of RFID in the logistics management of large manufacturing enterprises

in manufacturing enterprises, the processing time of materials and parts only accounts for 5% - 10% of the production process of enterprises through these parameters, 90% - 95% of the time is when materials are at standstill or in the logistics process of loading and unloading, handling, packaging and transportation, and about 80% of the working capital of enterprises is occupied by raw materials, work in progress, semi-finished products and other items: therefore, how to improve the production logistics of enterprises, Strengthening internal logistics management has become a practical topic of enterprise management

modern production logistics management is based on a large amount of logistics information, so the first problem to be solved is how to automatically input a large amount of data from the production process and management. Only when these large amounts of underlying data are entered into the computer, can the monitoring and control of production process, logistics management, production planning, scheduling and quality be realized. The emergence of RFID technology can solve the "bottleneck" problem of underlying data collection. It will greatly improve the automatic processing level of all links of logistics activities, improve logistics efficiency and reduce logistics costs

1. Analysis of the advantages of implementing RFID technology in large manufacturing enterprises

radio frequency identification (RFID) technology, referred to as RFID technology, is an automatic identification system that uses radio waves or microwave energy for non-contact two-way communication to realize identification and data exchange functions. Applying RFID technology to large manufacturing enterprises can not only solve the problems that bar code technology cannot solve or is difficult to solve, but also more importantly, it can solve the uneconomical problems that bar code can solve

1.1 the implementation of RFID technology can realize the visual management of inventory

the simplest RFID automatic identification system is composed of electronic tags, readers and antennas that send and receive signals. Any practical application should also include computer network system

therefore, applying RFID to track inventory - to realize inventory visualization, we must first achieve the following two points: (1) we must attach electronic labels to the items to be identified; (2) Corresponding label readers must be installed at the key nodes where articles are stored or used as testing instruments, and the price cannot be seen only. These key nodes include raw material warehouses, finished product warehouses and key processes in the production workshop. Therefore, when the article to be identified with the electronic tag appears in the reading range of the reader writer, the reader writer automatically takes out the agreed identification information of the electronic tag towel in a non-contact way, so as to realize the function of automatically identifying the article or automatically collecting the article identification information. In this way, the RFID reader can track multiple key locations where the items to be identified are stored or passed. This process is automatic without manual participation, which ensures the real-time and accuracy of data collection

in addition to the above two basic items, visual inventory management also needs a powerful computer network system to process the collected data and realize information sharing within manufacturing enterprises and even within the supply chain

1.2 Wenshi RFID technology can track, identify and control the whole production process. In the actual production process, it is very important to count the number of items in each position, workshop and warehouse in real time, and to track the current location of items in a certain batch number. The benefits of this approach are mainly reflected in the following aspects: the basis for logistics optimization, reducing capital occupation and Realizing Lean production; Capture and provide fast, scientific and accurate data information for new product development, precise formula, fine control and innovative decision-making; It can integrate with modern e-commerce and improve marketing level

in the production process, to track, identify and control the whole production process, we must first calibrate the elements of the production process, that is, code and mark the processing objects, processing plants (workshops) and workers. RFID tags support information writing. Using readable/writable electronic tags can mark any element that needs to be marked in the production process, and then meet the new needs of the automotive industry. Through the electronic tag automatic reader installed on the production line, the above required data can be automatically, real-time and accurately transmitted to the computer. In this way, real-time statistics can be carried out for the management of products and employees, etc

2. The application of RFID technology in inventory management

inventory management is a cumbersome and complex work for enterprises, which has to deal with a large number of document data every day. In order to settle every business in time, check the warehouse and goods flow, and ensure the safety of production materials and goods, inventory managers need to spend a lot of human and material resources and time to do data recording and statistical work. For example, using bar code technology (especially for large items, it is better not to know where the bar code label is placed), it requires a lot of manual intervention to scan the bar code, which has low efficiency and high error rate, and the accuracy and real-time of the information provided cannot be guaranteed: RFID technology is applied to the inventory management of manufacturing enterprises. Because RFID realizes the automation of data entry, it can reduce a lot of human and material resources, improve inventory management and reduce the average inventory level. Its objects include raw materials, spare parts, work in progress, semi-finished products, finished products, etc. through dynamic real-time inventory control, inventory costs can be effectively reduced

inbound and outbound. When the goods with electronic labels arrive at the warehouse, the reader at the population office will automatically read the labels without manual scanning. According to the obtained information, the management system will automatically update the inventory list. This process greatly simplifies the traditional goods acceptance and warehousing procedures, and saves a lot of labor-intensive work such as cumbersome inspection, recording, inventory and so on. Issue is similar to this receipt phase, which can realize automatic operation

count inventory. There is no need to manually check or scan the barcode during inventory counting, so the workload and unnecessary loss during inventory counting are greatly reduced, which provides managers with a greater degree of self tracking and management of WIP in inventory control. The tracking and management of WIP is to plan, coordinate and control WIP. The application of RFID technology can realize the automatic and rapid collection of a large amount of real-time data generated in the production process, and further assist the computer network to realize the real-time processing of data. The application of RFID technology makes it easier for enterprises to manage production data, improve product quality, reduce and avoid the backlog of semi-finished products, so as to improve enterprise efficiency

because RFID realizes the automation of data entry, it can realize more information collection and tracking operations, making the location of goods more precise and specific. Therefore, with the help of RFID technology, accurate inventory management can be achieved

3. The application of RFID technology in production logistics management

manufacturing not only includes procurement and sales, but also includes the production and manufacturing of converting low-value materials into high value-added products. Quick re sponse and agility are the key factors for the success of manufacturing industry. Production logistics is the core link of the whole logistics of manufacturing industry. Production logistics and production process are synchronized, which is the whole process of logistics activities from the purchase of raw materials to the delivery of finished products. Raw materials, semi-finished products, etc. move and transfer between processing points without stopping according to the process flow, forming a production logistics

it is a unique activity of the production enterprise manufacturing products. If production is interrupted, production logistics will also be interrupted: vice versa

with the help of RFID technology, electronic labels on raw materials, parts, semi-finished products and products in process enable production planning managers to quickly locate them and understand the consumption of raw materials. This will greatly improve the efficiency and quality of production; At the same time, RFID technology can also collect and process product information, and help production personnel easily grasp the operation of the whole production line and the production progress of products. Due to the readable and writable characteristics of RFID, it can provide constantly updated real-time data flow. Complementary to the manufacturing execution system, the information provided by RFID can ensure the correct use of labor, machines, tools and components. So as to realize paperless production and reduce downtime, and promote the smooth progress of production logistics

further, RFID is combined with existing manufacturing information systems such as ERP and CRM to establish a more powerful information chain, and realize the timely transmission of accurate data at an accurate time, so as to improve asset utilization, enhance productivity, carry out various measurements and support quality control

4. Suggestions for large manufacturing enterprises to implement RFID

the application of RFID technology will bring great benefits. But with great benefits, it will also bring great challenges to implement this new technology. Therefore, for large manufacturing enterprises, before implementing RFID technology, they must do a good job in the early stage planning, so as to lay a solid foundation for the successful implementation of RFID system in the future

(1) cost/benefit analysis. A cost/benefit analysis report is very important for the successful implementation of RFID. At present, there are still problems in the implementation of RFID technology, such as cost, technology, standards and so on. Some enterprises are still in a wait-and-see attitude towards the implementation of RFID technology; However, RFID technology can bring huge benefits, including indirect benefits, such as improving customer satisfaction. These should be included in the report, and the circular axis will analyze the investment income according to the actual situation below

(2) analyze the application system. Before implementation, it is necessary to clarify the business requirements of deploying RFID system and analyze these requirements. At the same time, we should fully consider various factors in the development and deployment of RFID system, and make overall planning. After the plan is completed, the plan should be handed over to the people who have the real decision-making power, so as to ensure that they will be truly implemented

(3) formulate the implementation plan. Combined with the application system analysis report, formulate the RFID implementation plan. The implementation of RFID project is divided into four feasible stages to gradually realize a smooth and slow transition. Namely: four stages: starting, testing and verification, pilot implementation and real implementation. For large manufacturing enterprises, the key is how to use RFID information. Realize the information integration with the existing system of the enterprise. Optimize internal business processes and improve the core competitiveness of enterprises. Although the road to RFID is not easy, the existing production stream needs to be reorganized. Conduct a lot of staff training. Interact with supply chain partners, etc. However, for those organizations that have the courage to accept challenges and vision. The application of RFID technology will bring great benefits. (end)
