What problems do enterprises currently encounter when implementing an MES management system? The MES management system is the core of informatized production management in manufacturing enterprises. Whether MES can be implemented and applied successfully is the key to achieving informatization goals such as improving production efficiency and reducing costs. However, for Chinese manufacturing enterprises with relatively weak informatization foundations, the complexity of MES causes various confusions when they select and implement MES. So what problems currently exist? Problems enterprises may encounter when implementing an MES management system:
1. Concentrated manifestation of contradictions from earlier informatization projects
The driving force for enterprises to implement an MES management system comes from earlier informatization projects, especially for customers whose ERP projects have been implemented and applied relatively well. During the deeper application of ERP, they discover that ERP alone cannot solve production management problems well, such as timely information feedback, quality management, advanced planning and scheduling, and so on. They hope that MES implementation can solve issues left over from previous ERP projects, so the contradictions and problems in earlier ERP and other project applications surface. For IT personnel, this is undoubtedly a huge challenge. In addition, MES is positioned as a manufacturing execution system, and many people regard it as a "life-saving straw," hoping that MES can solve all problems related to production management.
2. Knowledge gaps create psychological barriers At present, enterprises usually rely on two types of talent with different knowledge structures to implement MES management systems: traditional IT personnel and industrial control personnel (or equipment administrators). Because MES is a comprehensive project with strong cross-disciplinary characteristics, and because these two groups differ in their knowledge structures (IT personnel are not familiar with equipment, control, and so on, while industrial control personnel are not familiar with IT), whoever leads the project tends to face a certain psychological barrier before MES implementation. Even when an enterprise integrates these two groups into one project team during MES implementation, if the two sides lack a reasonable communication mechanism, deviations in understanding often occur. 3. Highly customized and involving the enterprise's core business MES management system implementation inevitably involves the core business of manufacturing enterprises, namely production, and it is highly customized. Therefore, enterprises are extremely cautious when implementing MES and often adopt conservative strategies. After all, production lines cannot withstand repeated disruption. 4. The system is huge, and there is little understanding of what should come first MES is a huge system. What are the logical relationships between modules? Which part should be implemented first, and which later? What are the prerequisites for implementation? All of this is very complex. 5. Unclear boundaries with ERP and other systems MES management system shares many similar functional descriptions with ERP, and there is also some overlap and intersection in functionality. So what exactly are the connotations and scope of MES? How should the boundary between MES and ERP be defined? Without in-depth research on both ERP and MES, this is difficult to determine. 6. Different suppliers focus on different priorities Because different MES management system solution suppliers enter this field from different backgrounds, their focal points also differ. Many functions seem to be needed by enterprises, but choosing a solution that truly fits their needs makes system selection and decision-making difficult.
In summary, before implementing an MES management system, enterprises must form standardized MES requirements in light of their production characteristics and management needs, and then use these requirements to guide implementation and application. The implementation of an MES system, like that of other information systems, needs to follow the requirements of information system project management.
