  • eScop

    eScop aims to overcome the current drawbacks for the shop floor control level such as MES and deterministic/real-time control, thus improving the state-of-the-art of the overall production control system architecture.

    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.
