Not Accurate
Resulting in weekly or monthly submissions of production plans that cannot be accurate to the day. The production data in the system cannot be updated in real time, and the lag is serious. Which is not conducive to the smooth progress of the production process. And restricts the further improvement of production capacity. At the same time, manufacturing companies have realized the existence of these problems. And are trying to use emerging technologies to solve them. Currently, some manufacturing companies use barcode recognition to improve the accuracy of data entry.
However, there are still technical bottlenecks in barcode recognition:
- The work efficiency of workers is different. Which is easy to cause uneven division of labor among groups.
- It is impossible to find production abnormalities and production line bottlenecks in real time.
- Low labor efficiency and low utilization rate of actual working hours.
- Once the barcode label is not clearly printed, there will be problems such as creases and difficult identification of the barcode gun.
- Real-time tracking is impossible. And it is difficult for the management to arrange work according to the work status. If there is a problem in a certain process in the work process. It must be eliminated until the next day.
- Barcode data collection requires a dedicated team of personnel to operate. And the labor cost is high.
Requirements
Therefore, the production line management system is increasingly unable to meet the requirements of enterprises. For efficient and lean production management. While deepening the modern management concept. It is of great significance to the enterprise to build a more technical production line management system.
