Warehouse Management in Logistics Management occupies a central position. Modern logistics processes to integrate, coordinate downstream responsibility, static inventory as possible, its business model is also based on the above assessment of the total cost of logistics. Because these two types of warehouse management in the business model is essentially different, but in actuality, such as storage, warehousing, sorting, tallying, etc. and difficult to distinguish, so the analysis must pay attention to their similarities and differences, these similarities and differences will be reflected in the structure of the information system.
With the changes in the manufacturing environment, product cycles are getting shorter, diverse small amount of production, inventory constraints have become increasingly demanding, and therefore must create and execute supply chain management system, using a computer, information technology the vendor, manufacturers, customers of the three closely integrated, shared inventory risk. Warehouse management can be summarized into eight key management modes: chase - close - Cha - Chu - pick - hair - plate - back.
Inventory control section is to determine the optimal warehouse business model, that is, to (according to the design requirements on the floor) to determine the warehouse management objectives and management, supply chain, if it is performed on a link and is a cost center, multi- quality of service, operational cost control objectives, the pursuit of reasonable inventory or even zero inventory. Therefore, precise knowledge of warehouse items of information is critical to the system, we propose to solve accurate warehouse management.
Warehouse management and precise positioning management processes throughout the enterprise plays a very important role, if you can not guarantee timely and accurate purchasing, inventory control and shipping, will give companies a huge loss, not only the performance of the management for the enterprise increased costs, and will result in customer service quality is difficult to be assured, and ultimately affect the market competitiveness. Therefore, we propose a new system based on radio frequency identification Warehouse Warehouse Management solution to solve the problem accurately. Here we analyze using radio frequency identification technology after the economic benefits to the enterprise.
ü convenient to read: read data without light, even through the packaging to carry out. Effectively identify longer distances, using built-in battery active tags, the effective recognition distance can reach 30 meters or more;
ü identification speed: Label one into the magnetic field, the reader can instantly read the information, and can handle multiple labels, to achieve mass identification;
ü hinder penetration and no screen reading: barcode scanning machine must be in close proximity and no objects blocking the case can only be readable barcodes. RFID can penetrate paper, wood and plastic metallic and non-transparent material, for penetrating communication, no light, reading distances. But not through metal and other conductive objects for identification.
ü Data capacity: capacity-dimensional bar code 50Bytes, the maximum storage capacity for storing two-dimensional bar code 2-3000 characters, RFID maximum capacity is several MegaBytes. With the development of the memory carrier, the data capacity is also growing trend. Future articles will be required to carry the amount of data increases, the label can expand the capacity of a corresponding increase in demand.
ü long life, wide range of applications: its radio communications, so that it can be applied to dust, oil pollution and radioactive environment high, and its closed packaging makes their life much more than the printed barcode; conventional barcode carrier is paper therefore susceptible to contamination, but RFID for water, oil and chemicals and other substances with a strong resistance. In addition, since barcodes are attached to plastic bags or cardboard packaging, it is particularly vulnerable to breakage; RFID label is the data in the chip, it can be free from fouling, RFID contamination resistance and durability.
ü tag data can be dynamically changed: the use of programmer can write data to the electronic tag, giving the RFID tag features an interactive portable data files, and write time is shorter than the print barcodes;
ü better security: RFID electronic tags can be embedded or attached not only different shapes, types of products, and can read and write data for the label set password protection, which has a higher security;: Because RFID is hosted electronic information, the data content via password protected, so that its contents can not easily be forged and fabricated becomes higher security.
ü Dynamic real-time communication: tag 50 to 100 times per second, the frequency of communication with the reader, so long as RFID tags are attached to objects in the reader's range of valid identification, its location can be dynamically tracking and monitoring .
ü small volume, shape diversification: RFID accuracy and do not need to read the paper with a fixed size and print quality, better suited to the smaller and more diverse morphological development in order to facilitate embedded or attached to the different shapes, types of products .
