Employment
Experience
- 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. - University Portalhttp://pg.edu.pl/welcome
A portal and set of microsites for the university. Deployed in a clustered environment.
- Lex Portalhttp://lex.pl
A portal and microsite for the leading Polish publisher.
