Introduction: Barcode technology organically links information systems of various industries, providing technical means for realizing the synchronization of logistics and information flow, effectively improving the efficiency of supply chain management.
Barcode technology is an automatic identification technology that has been developed and developed in computer applications. It is designed to achieve automatic scanning of information and is an effective means of collecting data quickly, accurately and reliably. The application of bar code technology solves the "bottleneck" problem of data input and data acquisition, and provides favorable technical support for supply chain management. It is by far the most economical and practical automatic identification technology.
Barcode technology has the following characteristics:
Advantages: fast input speed, high reliability, large amount of information collected, flexible and practical, easy to operate bar code equipment, easy to manufacture bar code labels, high efficiency, low cost, etc.
Disadvantages: easy to scratch requires outer layer processing protection, printing plane is easy to be uneven, easy to dust pollution, raw paper or post-marking curl, scanner specifications are different.
Application of barcode technology:
A bar code is a code that uses an optical electrical scanning reading device to implement data entry into a computer. It is a set of strips and empty symbols arranged according to a certain coding rule to represent certain characters, numbers and symbols, and the data barcodes composed of these strips and spaces express certain information, including static information. Product name, specification, quantity, manufacturer, etc.; may also have dynamic information such as batch number, assembly line, production date, shelf life, shipping location, arrival location, receiving unit, and waybill number. Barcode recognition converts the data represented by the bar code into data that the computer can automatically collect. The reading device is composed of a scanner and a decoder. The scanner converts the bar code symbol into a digital signal, and the decoder converts the digital pulse information into information represented by the bar code.
In the field of supply chain logistics, bar code technology is like a link that links information about the life cycle of a product to track the entire process from production to sales.
The specific application is as follows:
1, warehouse cargo management
The application of bar code technology and inventory management avoids the steps of manually writing notes and sending them to the computer room, which greatly improves work efficiency. At the same time, the problem of the lag of the warehouse information is solved, and the accuracy of the delivery date is improved. In addition, the problem of inaccurate bill information is solved, the quality of customer service is improved, manual operations in transaction processing are eliminated, and invalid labor is reduced.
2, production line personnel management
When each shift starts, each member of the work team scans the barcode on their employee card with a barcode data collector, records the attendance data and team members to the data collector, and then inputs them to the computer system. Based on the record, the team members decided on the corresponding rewards and punishments.
3, assembly line production management
In the period when bar code technology is not applied, each product must be manually recorded before the production line, and the process and parts required to generate the product must be manually recorded. The material of the material can be started after the material is distributed according to the records. Each product has a record form on each production line. After each process is completed, fill in the component number and your own work number. Manual recordings are large and complex, and they do not reflect the flow of goods on the production line in a timely manner. After the bar code technology, the order number, part type, and product number can be barcoded, and the labels are printed and pasted on the production line of the product parts and assembly. When the product goes offline, the quality inspection personnel of the production line will pass the bar code of the product, the production line code number and the bar code of the worker according to the process. The repair will be sent to the unqualified product, and the cause of the failure will be determined by the maintenance. Manual record.
4, warehouse management
Before the appearance of barcodes, there were many problems in warehouse management operations, such as the cumbersome process of materials entering and leaving the warehouse, the location where the items were stored, and the lag of information transmission, resulting in an increase in inventory, the delivery date could not be guaranteed, and the decision-making basis was inaccurate, which would lower the system. reliability. In order to avoid mistakes, some companies have added inspection personnel, which reduces labor productivity and affects the speed of instruction processing. If you have a factory equipped with a computer network system, you only need to add some barcode data collector before the data input.
5, purchase management
The product variety and quantity need to be checked when purchasing, and this part of the work is done by the data collector. Firstly, all the documents and product information of this purchase are downloaded to the data collector, and the data collector will prompt the material manager to input the number of the receipt, and the data collector determines whether the barcode is correct in the application system. If it is not correct, the system will immediately alert the material manager; if it is correct, the material manager will scan the item number on the bill of materials, and the system will then check if the items on the purchase order match the actual.
6, storage management
The porter (or forklift driver) simply scans the label on the bin that is ready for storage. The warehousing can be divided into indirect and direct: direct warehousing means that the material is stacked on any vacant position, and the logger address is scanned by bar code; direct warehousing refers to storing a certain type of goods on a designated shelf and establishing a storage location for it. Record.
7. Management of inventory goods
For label breakage, refer to the same kind or according to its location, make labels on the computer and subsidize. When the goods are shifted, the identifier is used for reading, the data is automatically collected, and the collected data is automatically transmitted to the computer cargo management system for management. According to the prescribed standards, the warehouse classified goods or scattered goods are regularly inventoried by the barcode reader. In the process of distributing goods, in the case of scattered goods of certain items, there are two ways: one is to repackage, the system generates a new QR code label, which is treated as a box; the other is the system setting. The inventory library stores the information of scattered goods, records the product name, quantity, location and other information of the goods, and manages them in a unified manner.
8, cargo information control, tracking
Automatic inventory warning: Automatic warning for the inventory of various goods above or below the limit. Combined with the recent average usage of various goods, automatic generation requires the purchase or cancellation of orders within a certain period of time; effective control of inventory. Space monitoring: monitoring the actual location of the goods, storage time, space and other parameters, automatically limit the irrational location, long storage time, lack of space and other provisions of the automatic warning. Tracking cargo information: Tracking the entire supply chain. Reporting damage processing: Automatically track the goods to be reported, the management personnel can register the damaged goods and fill in the application form for damages. If the application for damage is approved, the system will report the damages and report the damage details. .
9, out of the warehouse management
The bar code reader is used to read the bar code label on the outbound goods package, and the goods information is delivered to the computer, and the computer automatically generates the library details according to the number, product name and specification of the goods. The label was found to be damaged or lost by manual subsidy in accordance with the above procedure. After the goods have been checked and confirmed, the warehouse receipt processing will be carried out to update the inventory details of the goods.
Barcode technology has organically linked information systems of various industries, providing technical means for realizing the synchronization of logistics and information flow, effectively improving the efficiency of supply chain management, and is a necessary prerequisite for e-commerce and logistics management modernization. The role of logistics plays such an important role, and the shortcomings of bar code technology should be discovered and improved to make it better to play a role in logistics.
