Petr Baron, Assoc. Prof. Ing., Ph.D. is Associate Professor at the Faculty of Manufacturing Technologies with the seat in Presov, Slovakia. He is interested on computer support of engineering activities in pre-production stages, computer simulation of production systems and processes, simultaneous engineering, and risk management of technical systems. As part of the educational process, he is Guarantor of subjects in the first and second level of university studies for the Computer Support of Production Technologies study program and also a trainer of Ph.D. students both in full and part-time form. Marek Kočiško, Prof. Ing., PhD is a Professor and Head of the Department of Computer Aided of Manufacturing Technologies at the Faculty of Manufacturing Technologies with a seat in Presov, TUKE. His work focuses on computer aided of production processes, CAD/CAM/CAE systems, simulation of production systems, computer networks, virtual(augmented) reality as well as reverse and simultaneous engineering. His strengths include knowledge of PC hardware, computer networks, notification technology, excellent knowledge of operating systems, office systems, computer simulation systems, and CAD/CAM/CAE systems (Creo, Unigraphics NX, Solid Edge, etc.). Anton Panda, prof. Ing., PhD., is Associate Professor of study branch 5.2.51 manufacturing technologies, FMT TU Košice (Assoc. Prof.-2008), Professor of study branch 5.2.51 manufacturing technologies, FMT TU Košice (Prof.-2015). He has large experience in the engineering company supplying the products for demanding automotive, also farm and agricultural industry (Constructor of special purpose machinery and equipment, systems analyst, Head of the department of development and technical preparation of production, Methodist of statistical methods, Commercial and Technical Director, Director of quality). Since 2008 Anton Panda operates as Pedagogue and Scientist at the Faculty of manufacturing technologies TU Košice with the seat in Prešov, as well as Expert–Coordinator (Auditor) of quality management systems.
