Abstract:
In fuzzy
reliability analysis of generalized structural strength, fuzzy safety
state can be defined by state variation, fuzzy allowable interval,
generalized fuzzy strength. This paper studied the third case. Thus, The
concepts of maximizing set and minimizing set are developed to decide
the ordering value of each fuzzy number, and these values can be used to
determine the order of the fuzzy numbers. On the basis of the works
mentioned above, the membership function defining the fuzzy safety event
can be calculated, and then the fuzzy reliability in the case of random
stress and fuzzy strength is deduced. An example is given to illustrate
the method.
Key words:
Generalized fuzzy strength Fuzzy reliability Maximizing set
Minimizing set Total utility value
