Dependability and Risk Department (DRD) was established in 2004 at the Faculty of Mechatronics and Interdisciplinary Engineering Studies by the Technical University of Liberec. Since its origin we deal with research and practical application in the industry in the field of dependability, safety{security and risk (environmental, health and economical). We also deal with maintenance planning and optimization. The theoretical knowledge of the DRD members was used by the solving of research projects, industrial job orders and of course by the teaching of students within the academic work.
