With the intensification of market competition, logistics management should not only consider the distribution of goods from producers to consumers, but also consider the procurement of raw materials from suppliers to producers, as well as the transportation, storage and information transmission of producers themselves in the process of product manufacturing, so as to comprehensively improve economic benefits and efficiency. Therefore, modern logistics is a strategic measure to meet the needs of consumers and unify the market conditions such as manufacturing, transportation and sales.
Superb and constantly improving logistics ability, real-time supervision of logistics dynamic information system, identification of potential operational obstacles, and taking correct actions before the service provided to customers may fail, thus creating a perfect customer experience and gaining a lasting competitive advantage.
In logistics supply chain management, bar code technology can be applied to all links from product production to finished product off-line, sales, transportation, warehousing, retail and so on, for convenient and fast management. Bar code technology is like a link, which connects the information that occurs in all stages of product life cycle, and makes enterprises in a favorable position in the fierce market competition. Bar code can ensure the accuracy of data, and the bar code equipment is convenient and fast to use.
Taking a factory as an example, this paper introduces in detail how to combine the application data collector with the user's computer system to solve the problems of product parts warehousing, production line management (personnel and production management), off-line warehousing, sales, access and distribution of finished products. After-sales service and other aspects of the process.
1. Production line personnel management: At the beginning of each shift, each member of the working group should use the data collector to scan the bar code on his employee card and record the attendance data and team members in the data collector; And then input into the computer system. All members of the team can be paid or punished according to the output and quality of the day.
At the beginning of machining operation, scan the work order of the day or the bar code on the workpiece to be machined to indicate the start of a task, and then scan it again after machining. The bar code data terminal installed in the work area receives these data, automatically adds the group number and time information, and uploads the information of each employee to the PC after work every day. Calculate the productivity of this group of workers systematically and encourage the members of the production group to improve their labor productivity.
2. Production management of assembly line: firstly, the order number, part type and product number are formed into barcodes by using barcode technology, and the barcodes are printed and pasted on the production line of product parts and assemblies. In this way, the production process of product orders on a production line and the required materials and parts can be easily obtained. After the products are completed on the production line, the product bar code and the bar code number of the production line are scanned and input by the quality inspector of the production line, and the workers' bar code is scanned in the working procedure sheet (which can be confirmed once and cannot be changed). For nonconforming products sent for repair, the cause of failure (process position) shall be determined by maintenance. The whole process does not need manual recording.
3. Spare parts, product storage and distribution management In a factory that has installed a computer communication network, it is only necessary to add some bar code data collector equipment before data entry, and it is possible to receive considerable benefits with a small investment.
* In order to issue a receipt or perform any other operation, the material manager must first select the material receipt processing menu from his barcode data collector, and then start scanning the barcode labels usually affixed to the material packaging by the supplier in advance. The bar code on the label indicates all the information needed to accept the product, which can be quickly and accurately input by the material manager through scanning. If the supplier does not provide this information in the form of bar code, the material manager will input this information into the system through the keyboard of the collector, and the system will immediately generate bar code labels for these materials.
Check the variety and quantity of goods when buying them. This part of the work is done by the data collector. First, download all the purchase documents and product information to the data collector, and the data collector will prompt the material manager to enter the purchase order number. The material manager scans the bar code of this number first, and then the application system of the collector judges whether the bar code is correct. If it is not correct, the system will immediately warn the material manager. If it is correct, the material manager scans the item number on the purchase bill of materials again, and then the system checks whether the items on the purchase list are consistent with the actual purchase.
Next, the material manager scans the material specification information (volume, weight and composition, etc.). ) and the identification number. This identification number uniquely identifies the purchased materials and is used as the most basic information in all future inventory management links. If there are materials that do not meet the order, the system will give corresponding information.
* The warehouse management porter (or forklift driver) only needs to scan the label on the material box ready for warehousing and the label on the shelf ready for storing this box. Warehousing can be divided into indirect warehousing and direct warehousing: indirect warehousing refers to recording the address of materials by bar code scanning after they are stacked in any vacancy; Direct warehousing refers to the storage of certain goods on designated shelves. Establish records for each material box and its storage location through warehouse management.
* Material management refers to the operation of extracting raw materials and semi-finished products from the warehouse according to the batching task. The process is as follows: firstly, the staff scans and inputs the barcode numbers of batch tasks on the portable barcode data terminal. The screen of the data collector shows which raw materials and semi-finished products are assigned to the task and where they are stored.
The material elevator receives the material and scans its identification number for verification. The system records the suggested materials and establishes tracking files. * Sales delivery management should be combined with all commodity orders of the same customer. First, the order is divided into containers, or the full load of batches and pallets can be determined according to special circumstances or containers.
After the operator selects the sales delivery mode from his barcode data terminal, he scans the barcode on the delivery box, and the system will confirm whether the box contains the items on the delivery list and whether the quantity and variety are correct. When there is a difference between the quantity to be delivered and the actual delivered quantity, the system requires the operator to input the original code to explain the difference, and then the system resets the code and reports it. In this way, the system has certain flexibility, allowing operators to load more goods when the pallet is not satisfied, or to extract some goods when the pallet is full. Finally, the system clears the out-of-stock goods from the database and indicates that the order has been picked up.
4. Market supply chain management This is the most widely used and effective application at present. In sales management, there are two ways to collect data. One is to tear off a bar code from the product at each link and take it back for scanning. The other is to scan records immediately with a data collector. Either way, you can record which product, which department, who you sold it to and which order or contract you completed. With these basic information, it can be easily analyzed and counted.
5. Management of after-sales service After-sales service directly affects the image and sales of an enterprise and requires a lot of investment, that is, good service and low investment. This is a contradiction. If you want to solve it well, you must have correct and timely data as a guarantee.
If the user complains or guarantees, how can the manufacturer know whether the product is under warranty, whether it is officially sold, whether it is original, whether it has been repaired before, and so on. Barcodes affixed to products, packages, warranty documents and product documents can be the same or different, but they have corresponding relationships.
When users have warranty or quality complaints, you can immediately find out when, where, who sold the product, what the price is, the contents of the sales contract, warranty records, which supplier provided the faulty parts and who installed them. Suppliers or distributors may be held accountable. Through the after-sales service system, we can not only count the product quality laws, but also improve the service quality and reduce the service investment.
The combination of bar code technology, product and user's application system plays a great role in all application links of users. With the rapid development of information technology and the increasing popularity of enterprise informatization, manual goods management in logistics warehousing, logistics distribution, manufacturing, postal service, book management and other industries can no longer adapt to the development of market economy, and mobile data acquisition information system is urgently needed. Portable data collector has become an indispensable key equipment. As a fast and efficient mobile information collection and processing terminal, barcode scanning PDA has a very broad application prospect in national defense, public security, medical care, industry, finance, commerce, postal service, cargo transportation and other fields.
