Services a system delivers are called dependable when it is trustworthy enough
that reliance can be placed on them because they are available, reliable, safe
and secure. In the contribution, our approach to modelling and design of
components for the construction of dependable time-critical systems implemented
by means of RT kernel is presented. On top of that, faults and errors in
components and RT kernels are classified in the contribution. Safety of the
components is verified by means of the UPPAAL tool. Reliability is solved by
means of time-redundancy and spatial redundancy, both implemented on RT task
scheduling level. Proposed solution is analyzed from view of schedulability of
the resulting time-redundant set of RT tasks and its implementation is
demonstrated by means of uC/OS-II kernel.
