RFID-based manufacturing execution system and application case
1. RFID application background and demand
1. The new situation facing the manufacturing industry
· Short product life cycle · Rapid growth of multi-variety and small-batch production methods · Rapid market changes and unpredictable
2. Change of production process management
· JIT and lean production are becoming more and more popular. The demand for coordination in all aspects of production is increasing. How to accurately and timely solve the tracking and management in the manufacturing process. How to adjust the production process in time to adapt to the production of multiple varieties and small batches the way
3. Problems faced by the manufacturing industry
· There is no unified data view of real-time production information in the workshop, and the system is difficult to integrate. • There is a gap between the enterprise resource system and the workshop production. • Many and complex systems lead to inconsistency in real-time information and lack of standardization. • There is a gap between the process control system and the manufacturing execution system. · Failure to detect and prevent possible problems in the workshop production process
In response to these problems, although the idea of ​​lean production is advanced, how to implement its concept into practical work? First of all, we need to find a way to implement the concept. Second, we must establish means and measures that can operate in the workplace. Finally, we must implement it in production activities. We must rely on such a process to implement it.
Let's analyze the bottlenecks facing the manufacturing industry: Lean production involves the collection, transmission, and processing of information. At the current stage, the development of enterprise informatization in the three parts is inconsistent. The bottleneck problem is largely from information collection.
Lean production requirements for information collection:
· Real-time: collect and upload production line information in time · Accuracy: ensure the accuracy of the collected information · Information collection scope: collect all kinds of information needed to implement lean production
In the process of implementing lean production, the material flow and information flow cannot be synchronized in real time, resulting in a series of problems. Enterprises lack technical means and systems that can support the real-time synchronization and coordination of the above material flow and information flow. As a new type of automatic identification technology, RFID technology can effectively solve the problems in the synchronization of material flow and information flow.
