This paper concludes that barcode / RFID technology improves the role of manufacturing ERP, SCM and other applications, indicating the benefits of bar code and ERP integration applications, highlighting the huge potential to fully improve the manufacturing process through integration with AIDC.
ERP / SCM demand for data input and information collection
ERP / SCM data input range
After completing operation of ERP or other other application systems, data input and information collection become a system that is important and heavy. It is well known that the business process of the ERP / SCM system is seamlessly integrated, and the integration of the design reasonable ERP / SCM internal data does not require repetitive input of a large amount of data. However, there are two situations that the system itself cannot be solved, one is the original data into the system, and the other is the collection of logistics status:
The original data appears between the ERP / SCM and the external system or between the supply chain partners, such as the interface between the customer or supplier, typical raw data, such as:
1. Sales orders and customer information
2. Supplier information
3. Information of the material transfer process of supply chain independent units
4. Financial vouchers with materials
The information of the logistics state occurs during the logistics process, and ERP is the "3 stream" integration of logistics, capital flow and information flow. In the real situation, the information flow and logistics (including fund flow) are time difference. Due to the difference in information acquisition means, the information flow is delayed in logistics, solving or decrease this difference is the application of information collection technology. Typical things, for example:
5. Identification and input of entry into the library material and the location
6. On-site identification, traffic information, and quality information collection and input
The six data of the above examples, we call it "first" data, they cannot be derived from the internal data inside the system. In response to it is "2nd" data, such as delivery items, purchase order projects, work order projects, etc., they are data generated in the system, for integrated ERP systems, there is no re-input or acquisition process .
Here to discuss and solve the problem of "first" data, it is also a difficult problem for traditional ERP implementation.
Traditional data input process
The information system data input method generally includes identification, cleanup, and input 3 artificial links.
Identification: Check the pre-printed list, check from a large reality part, the label, the water card or certificate, and then the quantity of the list, the record result;
Cleaning: The identified data will be identified, and the format of the information system requirements may be considered to be the process of data transition into information;
Entry: Enter the system by entering the system by the interface provided by the information system to complete the data entry.
Such a process has a large number of orders, procurement, product storage, supporting library, material flow transfer, etc., integrated ERP / SCM system provides menu mode, prompt input mode, input error correction, etc. However, it is undeniable that the ERP itself has no way to automate the identification of jobs, identify the gap between the ERP system logistics and the information flow, and completely solve the integration of logistics and information flow, the best way is bar code and RFID such as advanced digital identification. Application of Technology.
Data input accuracy and timely
ERP is a real-time online management system, ERP data height sharing and data share use in different subsystems, resulting in high requirements for data time and accuracy, and the information is not in time must affect the efficiency of the system. The inaccurate data will reduce the credibility of the system, and even misleading the production and operation of the operation. Test indicates that in general, the skilled types of typesperes will have a average 300 times button with a hand-key disk input, and the general administrators or inventors will be much higher. Plus heavy artificial identification, low work response speed and error is inevitable. The accuracy of the general bar code scanning equipment is more than 99.9999%, and the speed of barcode data acquisition is also unacceptable, and efficiency is much higher than manual input.
Barcode and automatic identification technology
The most widely used is a linear one-dimensional bar code. Since the capacity of one-dimensional barcode is limited, a one-dimensional bar code is often used to identify key fields in the database, such as keywords or keyword combinations, a large number of data stored in the database, so the barcode system in the manufacturing enterprise must Integrate with ERP / SCM system, unlike the bar code application integrated with ERP system, even if it is successful, it will also form "Island Success".
The two-dimensional bar code that appears in 1988 can achieve more information capacity in smaller space, expand the amount of information to thousands of characters. The barcode itself is equivalent to a portable database or data file, which really implements the use of barcode to materials, can travel with people, packaging, workpieces, documents, cards or labels. In addition, it also has the characteristics of encryption mechanism, high reliability, and error correction, which can represent image data and represent a variety of language information, etc., which opens up a broader application for barcodes.
Although barcode or other automatic data recognition technology is constantly evolving, its role is only in data acquisition and processing, it will show its huge power after the application of enterprise applications such as ERP.
Barcode and ERP integrated application
In the manufacturing industry, barcodes can be applied to the entire process of supply chain or ERP, which will now explain the application of bar code technology in the manufacturing enterprise.
Example 1: Receiving reception
Even if it is successfully applied, the arrival management system of ERP is also required to enter the system to enter the system, and then find the procurement contract, the purchase order and correspondence, is a very cumbersome process. Smart software can provide a specific range list by page or form selection to reduce some manual input, reduce workload and increase accuracy. Even so, the identification of the goods is still the bottleneck of the entire logistics process.
Barcode technology will change the traditional process of the delivery process.
Almost all advanced companies now, large companies require suppliers to attach the standard cargo bar code label of the owner's outer packaging of the shipping goods, and can identify the material code and supplier code to clear, some enterprises use two-dimensional barcode to The goods label can more information.
After using barcode delivery labels, the system's operational process will change much:
1. The delivery of the material directly collects the data directly after the scan, automatically completes the process of the goods and the purchase order, improved the efficiency and implementation of ERP use;
2. At the same time, you can support direct delivery. The process time of purchase to storage is greatly saved, reducing the cost of the warehouse area, material handling operations and other material processing, is a must Indispensable measures.
3. The data label data has been decoded to improve the level of raw material batch tracking level, which is convenient to find the source and place of materials, this for the implementation of ISO9000, or uses recurrent industries (such as cars and Medical equipment) and military production can greatly improve tracking response speed, reduce quality cost and help to save the credibility of the company.
Example 2: Raw materials and semi-finished stocks
In the case where there is a delivery label, and there is material to go on the delivery label, the material reaches the warehouse or workshop, and the bar code label is scanned with a hand-held scan terminal to record the arrival of the material. Host Controller, Warehouse Management System (WMS) or ERP system issues the material to go - place, warehouse library, and forecasting its consumption progress. The liberator or worker is stored in accordance with the instruction, and the barcode tab at the location or production line is scanned to verify the location of the material. Each scan guides the implementation of the next task and updates the data of the ERP system. When inventory inventory, the barcode will greatly improve efficiency, reduce the time of inventory freeze. By holding the wireless terminal, the inventory product information is collected, and the collected information is collected by the computer, thereby forming a count report.
Barcode and ERP integrated systems can reduce 30% processing cost, improve logistics flow speed, and improve inventory, tracking of products or finished products.
Example 3: Scene and in Product Management
Most companies apply barcods on the final product to leave the factory's delivery label, which is mainly played in the customer or returning. The more efficient role of barcodes is the identification and tracking of the part during the production process. The deepening the barcode interventional production process, the greater the cost of labor and material costs.
The most common method of field re-article tracking is to label on the assembly, such as information of the important zero component, such as the car, computer motherboard, computer engine, computer motherboard, in each station, such as car engine, computer motherboard, The serial number of the hard drive, etc. After each process is completed, the ID number, completion time, inspection information, etc. of the work worker are scared, and the next process is driven.
The barcodes of the article can achieve comprehensive tracking from raw materials to the final product. When there is a problem with some of a supplier's raw material, it is possible to accurately determine the range of parts or final products, whether it is in stock state or has been shipped to customers. Reduce the range and cost of product recovery. Barcode production tracking systems can also automatically establish the quality tracking and working history documentation required by the ISO quality assurance system to achieve complex batch tracking. Thus the application bar code can promote the development of the new manufacturing process.
For the manufacturer of ETO / ATO mode, emphasize the identification number of individual products corresponding to the customer's order number. Different product configurations have different processes, so in the ETO / ATO production mode, the process process of ERP field system needs to be used. The "backbone barcode label Piggyback Labels" is synchronized by the card (flow card). After the loading of the product, the specified barcode label is peeled on the process process card and attached to the corresponding assembly. Scanning the barcode of the assembly and the bar code loaded into the part, ensuring that each customer-customized computer is correct, as a basis for quality tracking.
Example 4: Quality Control
Production tracking of materials or batches can reduce the scope of waste or rework when discovering defects, thus not only reduce a large amount of labor and material cost, but also to save time loss. The key to quality tracking is still a record of the production process. The use of barcodes can also be applied to the tracking and quality control of materials in various phases of material tracking.
RFID and ERP combined with IT New World
RF recognition RFID introduction
In enterprise applications, the most promising automatic identification and data acquisition technology Automatic Identification Data Collection (AIDC) is RF Identification Radio Frequency Identification (RFID) technology. The RFID system consists of RFID tags and readers:
The RFID tag is an integrated circuit IC chip with an antenna, and the data has an IC, and communicates with external communication. The size, operating mode, and accuracy of the RFID tag have many kinds, and the cost is also very different. It can first use different types according to the needs of different enterprises. The RFID reader consists of one or more antennas for accepting and transmitting signals to consist of a microprocessor that receives signal decoded. The processed data is associated with the ERP system host via a conventional cable or local wireless network WLEN. The reader can be made with the handheld terminal, or it can be fixed, installed in some position, such as the entrance of the factory, the door, shelf or production line. The label information is sent over the radio frequency. RFID does not require visual contacts necessary between the object and the card reader. Thereby, the identification and information stored procedures can be completed in the case of unattended tubes. RFID can be read out through a plurality of materials other than packaging, transport containers and metals. You can read up to 12 RFID tags at the same time.
RFID application potential in manufacturing
Generally, the label of the RFID chip is generally referred to as "dexterous label smart label". This new identification and communication technology first is widely used in supply chain management. The US important consulting firm Gartner said that the application of RFID in the supply chain will change the process of the entire industry. Many famous manufacturers and retailers are generally introduced in logistics management.
We are more concerned about the huge potential of RFID label in the manufacturing industry. In the manufacturing industry, the RFID has the advantage of RFID and ERP or SCM integration in addition to the barcode and text of the label.
N provides real-time tracking on products and raw materials
n Dynamic update or overwritten information on package or label, do not require manual intervention or not to complete the information of product information in a visual environment
n Reduce the information transfer and acquisition of supply chain handover, so that you can get or read information from ERP / SCM database.
Here are some examples already applied;
n The real-time positioning system can be used to track the location of the finished product, such as military vehicles, construction machinery production, automobiles, etc.
N Passed the RFID tag on each of the finished products that leave the production line, which can be easily tracked from each product during the movement of the loading and transportation.
n In Lean Production, use RFID to form a label production solution in the article tracking system. The parts are posted on the shelf on the shelf of the product buffer in the parts. When the components are consumed to the specified boundary, they can transmit signals to the upstream signal notification production supplemental components. This automatic board JIT system greatly improves the visualization and reaction speed of lean production.
N RFID Realization Automation of Workshop Field Data Acquisition. As long as the part enters the production line or reaches the completion area, the automatic recording process, the device and the worker's ID number, processing time avoids a large number of manual hysteresis data inputs, barcode scans and other operations and the possible incorrect data brought. . A complete resolution of the information on ERP system MES to obtain bottlenecks.
n Complex Product Sales and Maintenance Services, the RFID tag on the product is a database that moves with the product, ready to read its history and quality records, avoid manual delivery of written materials or access to the remote host database.
ERP and barcode / RFID integration applications
The bar code is easy to use, high cost efficiency, and has a powerful tool for providing accurate data to enterprise applications for the largest application. Further improvement in the efficiency of enterprise applications will be largely dependent on the application and development of barcodes and communication technology.
ERP can get huge benefits from barcode applications. Such as:
n Improve the real-time performance of ERP data acquisition, improve the reaction sensitivity of the entire software system
n Reduce most of the heavy business processing workload and time
n Full improve data accuracy, improve the credibility of the ERP system on inventory, plan, progress control
n Provide complete materials and quality tracking
n Provides a tool for further simplification and automation.
It must be seen that as most enterprises and products are transformed from the MTS to the ATO or ETO mode, from a large number of production methods to lean, including raw materials, in products, parts, parts, and final products, all materials, all materials, all materials, etc. Track and control It is more important to be more and more important. Materials and quality tracking will be the heavy task of the ERP system. The use of automatic identification and data acquisition means such as barcodes is an effective way to resolve this increasing information identification and acquisition issues. We believe that the integration of advanced automatic identification technology such as barcode is not only for the supplement to ERP data processing means, but also integrates the real logistics and information flow of ERP, and play a powerful lever for the full function of ERP. .
Conclude
Advanced bar code printing system, RFID delegated label, wireless connection, etc. New technology can provide the necessary real-time and precise data for the enterprise ERP system. RFID brings new concepts and features to greatly simplify the original complex structure and process of ERP. Their combination will bring new concepts, new features and new growth to the manufacturing, logistics industry, and supply chain management.
