Corroding constructions, fuzzy parameters of aggressive environment, α-level setsAbstract
This work is devoted to the creation of new models of metallic constructions behavior with changing geometric characteristics as a result of corrosion and effective digital algorithms of their computer implementation with fuzzy information about environmental parameters.
Fuzzy information is formalized using the theory of fuzzy sets. A new mathematical task statement of durability prediction of corroding constructions with fuzzy parameters of aggressive environment are formulated. Rate of corrosion is considered as interval value given by linguistic variable value. Linguistic variable degree of "aggressiveness of the environment" is considered. Aggressive environment parameter is presented as expansions in α-level sets.
The result of the solution of the prediction of durability will be a tuple of values of durability of construction. It is converted to a clear number by the known methods of the theory of fuzzy sets
