The application of bar code technology in the logistics.


Bar code technology in the proper use of modern logistics industry, can greatly enhance the degree of automation of the logistics operation to reduce the operation of data entry errors and improve the efficiency of enterprise logistics management. Disharmony in the logistics process for the production efficiency in modern production have a significant impact, chaotic materials warehouse, the implementation of complex production preparation and procurement plan is almost the problems encountered by all enterprises. The implementation of the logistics management information system to a certain extent to solve this problem, but the system only provides a management mechanism, there would still be many difficulties in the specific operation. Data acquisition, for example,  in certain industries, automation technology, artificial means of data entry error rate may be as high as the SXSX, its negative effects can be imagined. Barcode logistics management can greatly reduce such errors, while improving the efficiency of logistics management. 


Rejuvenated mature technology 


Bar code applications in China is approximately from the mid1980s. Today, the  bar code applications across all walks of life, all over the world like an economic information link manufacturers, exporters, wholesalers, retailers and customers organically linked. However, in the application process, the onedimensional bar code technology but there are still difficult to overcome the defects. The capacity of onedimensional bar code is very limited, subject to the restrictions of the code system and the reader device, generally speaking only a dozen bytes, it is  difficult to record detailed information of the merchandise. The other hand, the  rate of onedimensional bar code reading poor. In order to solve the above problems, researchers continued efforts to promote  a twodimensional bar code as the representative of the birth. These  twodimensional bar code technology has been stepbystep "middle age" bar code technology rejuvenated, and laid a solid foundation for the further  application of the bar code in the field of logistics. 


Introduction to secondline bar code 


Twodimensional bar code is developed to address these problems. For example, the use of advanced mathematical methods, can be stored in a small  area of about 1000 bytes of data. Also has a strong error correction capability,  eight error correction (ECC 2:8) damaged 50% can still be a complete recovery  of data. 


Dimensional bar code extension data indicates the range. The onedimensional bar code can only record digital or letter, the twodimensional bar code can  represent a variety of digital information. Such as the use of can store  Chinese characters, which is not easy to achieve in a onedimensional bar  code. 


These featurerich of the twodimensional bar code bar code in the logistics  field. Large capacity to provide more management may only record the lot  number or category of goods in the past, features and more detailed records of  goods. This amount of change is actually brought about a qualitative change. Just a  simple bar code database indexes, while the twodimensional bar code actually  become the "identity card" of items, all of the information does not need to rely  on the existence of the database. In the case of onedimensional bar code, the supply chain under the  Lconvergence there is a certain problem, which is on the upstream and  downstream enterprises must have a shared database exists, the only way to  ensure that the information can flow, or else bar code upstream business  become waste, and the upstream and downstream enterprises can not use. With the twodimensional bar code, the use of XML and other modern information technology, supply chain upstream and downstream enterprises only need to follow the same specification can exchange data. 


Enterprise data  is still maintained, both to maintain the privacy of the data to ensure that the  data whether the unobstructed flow in the supply chain. Can be seen. 2D barcode technology has brought revolutionary changes in  logistics and supply chain management, but also makes difficult to achieve  management initiatives has been the way of implementation. The application of bar code technology in logistics management application The application of bar code technology in the logistics management of all  aspects. The bar code should not be seen as merely a substitute for the  keyboard input mode, in practical applications, because the bar code may not  be achieved in the past management features, use the bar code may  significantly alter the existing supply chain management model. In this sense,  the implementation of bar code technology for logistics management is a  process of the BPR (business process reengineering). The following discussion  is only a few examples of the application of bar code technology in the logistics  field.


@ Bill of Materials Management

Productionoriented enterprises, materials management, enterprise resource  planning. In the Materials Management application of bar code benefits are  many. First, the bar code can be used as the WIP (PorkIn Process), the identity  of the state, to accurately determine the consumption and supply of materials;  Second, the bar code on the identification of materials laid the foundation for the  establishment of the product files. Reflected through the bar code data,  managers can easily learn the source and batch of a finished product of critical  importance, these data can be used as the feedback input of materials  management, the formation of the closedloop control by the Materials  Management. In the domestic bar code used in the materials management have been many  success stories, such as Shanghai Volkswagen and other largescale  manufacturing enterprises.


@ Operations management

barcode applications in operations management is mainly reflected in the bar  code to the linked workflow tools. Warehousing operations, for example,  inspection, stocking, sorting, shelving and other aspects of the link between the  very complex. In the traditional mode of operation, business center and  warehouse staff in general a paper document exchange to complete the  convergence of workflow. After the application of bar code, the semiautomated  job management can make use of wireless LAN. Business center business  instructions via the wireless network directly under to reach the warehouse staff,  warehouse staff via handheld terminals receiving instructions, and scan the bar  code to confirm the accuracy of the completion of the work of the warehouse  staff to complete the situation immediately returned the business center has  been confirmed. Compared to paper documents, the use of barcode and wireless networks can  greatly improve efficiency at the same time, the bar code, thereby greatly  reducing the possibility of misuse, and promote the improvement of the  workflow. 


@ Warehouse Management 

Storage management is in fact the traditional territory of the bar code  applications, and its application throughout the storage, inventory, inventory  management and other aspects. Out of storage, bar code can accelerate the speed of the human library, can  also reduce the errors of the human library.The biggest change is the barcode warehouse management inventory in the  inventory business, the traditional manual approach is the use of pen and paper  record, is not efficient at the same time existing data may be inaccurate. Use of  bar code, it is possible the use of automation technology. Use handheld devices  such as in a warehouse, inventory only need to use handheld terminal  scanning box, all inventory data will be recorded in the handheld terminal,  handheld terminal will automatically handle inventory repeat error. Handheld  terminal data can be easily imported into the management system. Inventory management, bar code on the significance of the cargo assurance.  


We know that the logistics management system to do resource planning, often  need to reference the information of the goods, but the shelf operating under the  traditional way, difficult to avoid the disconnect of goods and cargo information.  Often happens is that the logistics management information system indicates a  kind items in the library somewhere, but the forklift operator to open the arrival  position is found that there is no such items. Bar code technology can not only  identify all items, and can also identify the cargo space. Requirements only to  scan the cargo space of the bar code and the goods bar code to complete the  upper and lower frame process, you can ensure that the goods cargo  information is always accurate. Barcode technology and information system interfaces 


Finally, we talk about the barcode recognition technology and information  system interface. In general, barcode creation reader has a readymade  package can be used. Information systems has been considered in the planning  and implementation to the needs of the bar code, then the increased workload  is very small. However, if the information system has been formed, and  requirements of the secondary development to increase the bar code support,  the issues involved in more trouble. In the latter case in general to rely on the  openness of the information system itself. For example, can make use of ERP  software on behalf of the SAP system, SAP provides the RFC interface or  DCOM components to add a bar code support. Logistics as a macroscopic system, just a small piece of bar code applications.  But its application is likely to bring revolutionary changes in logistics  management. Domestic logistics industry, most of the application for the bar  code is still in the exploratory stage, it also means that the possibility of  innovation still.
