Fuzziness and subjectivity are inherent in a system reliability analysis. This paper mentions the fuzziness and the subjectivity in estimation of a failure probability and an error probability, in modification of the failure probability and the error probability taking the influence of environmental conditions into consideration, in estimation of the dependence level, in evaluation of system reliability and safety. This paper also mentions one of fuzzy sets theory approaches in the system reliability analysis to deal with the fuzziness and the subjectivity. In this approach subjective unreliability measure represented by a fuzzy set is used, and informations on reliability, e.g., reliability estimate, dependence level estimate, are represented by natural language.
