Experience
eScop
This goal is achieved by introducing an innovative approach based on the combination of 3 different pillars namely:
i) embedded systems
ii) ontology-based knowledge management
iii) service-oriented architecture
This approach is called an Open Knowledge-Driven Manufacturing Executing System, or OKD-MES.
One of the main results for the eScop project is a service-oriented middleware that should allow them to build and simulate a factory and process control systems.
