RFID makes production management and parts management more "flexible"

　　This is an area where RFID has been practically used for a long time. Most manufacturing industries have gradually transitioned from mass production to the so-called "more varieties and less quantity" production methods. Even on the production line, it is extremely important to complete the same work in mass production with the same accuracy in the shortest possible time. But because there are many varieties and small quantities, as each product changes, the process flow will change accordingly. For all varieties, you must remember their operations, to complete them with high precision, it takes a long time to become proficient, and the probability of error is relatively high.

　　In addition, for the products to be assembled, referring to the barcode and information system on the operating instructions, the operator can maintain the correct parts and the correct order to assemble, which improves the accuracy of the assembly work. But at the same time, a work of reading barcodes has been added.

　　I thought that "it can be done in a few seconds at most", but there may be dozens of places that need to be read on the production line. As far as the entire factory is concerned, the number of barcode readings is thousands, tens of thousands, or even more. As the correct rate of barcodes that can be read increases, production efficiency increases. However, if there are too many places to read, the productivity may decrease instead. From the point of view of the operation site, it is difficult to read the barcode if it is dirty or rubbed off. From this perspective, the advantages of RFID have been recognized and started to be implemented.

　　Using RFID, you can understand what the next product is without increasing the number of readings. For workers, not only can the process be accurately displayed, but also the working time used by each person can be calculated. This is another advantage of implementing RFID technology.

　　If a certain process takes too long, and the product is continuously put in, this process will form a "bottleneck" and may cause the entire production line to be forced to stop. Therefore, more effort is required in the production input sequence to stabilize the operation. Therefore, the budget of the time required for each process is very important for the input design of the production line and the arrangement of the process. This is no longer only dependent on long-term accumulated experience, but can also be used to adjust the input sequence and improve the process through the actual results achieved by RFID. The multi-variety and small-quantity production methods also affect the procedures for ensuring the supply of materials and processing parts. The operation instructions of the production process are also different every time, because the parts assembled are different each time.

　　First of all, due to the increase in product types, more types of parts have to be processed than before. Secondly, the production volume of each product is very small, so that the inventory of each part is reduced accordingly. Therefore, more and more efforts are made to improve the accuracy and efficiency of the inventory management of multiple varieties and small batches of parts. Since RFID technology is suitable for managing parts and components, attempts to solve the above-mentioned problems have been initiated early. Sticking an electronic label on each product is expensive to implement, but there have been some successful cases in the management of parts and components in batch units. With RFID, even if the process changes frequently, parts can be supplied flexibly and accurately.
