Risk and reliability analysis is increasingly being
used in evaluations of plant safety and plant reliability. The
analysis can be performed either during the design process or
during the operation time, with the purpose to improve the
safety or the reliability.
Due to plant complexity and safety and availability requirements,
sophisticated tools, which are flexible and efficient,
are needed. Such tools have been developed in the last 20
years and they have to be continuously refined to meet the
Two different areas of application were analysed. In structural
reliability probabilistic approaches have been introduced in
some cases for the calculation of the reliability of structures
or components. A new computer program has been developed based
upon numerical integration in several variables.
In systems reliability Monte Carlo simulation programs are used
especially in analysis of very complex systems. In order to
increase the applicability of the programs variance reduction
techniques can be applied to speed up the calculation process.
Variance reduction techniques have been studied and procedures
for implementation of importance sampling are suggested.
