ResumoThis paper presents some contributions to the development of the methodology for the evaluation of subjective uncertain factors such as omissions, mistakes, incorrect modeling, construction errors, etc. By using fuzzy sets theory, failure event can be defined in the more flexible form than the usual form. Especially, the concept of fuzzy probability aids to derive a new reliability analysis which includes the subjective assessment of engineers without introducing any additional correction factors. Several numerical examples are presented to illustrate the analytical method developed herein.
