Abstract

Annotation. Purpose. The problem of estimating the maximum value of the longitudinal force, which compresses the cylindrical orthotropic shell under the influence of external pressure, torque, accounting for one limiting state, local loss of stability, and also the presence of fuzzy initial data - geometric characteristics is considered. Methodology. To solve the optimization problem, a simulation procedure has been developed in the work, the actions of which are based on the use of the Monte Carlo method. Findings. A procedure for fuzzy modeling of the maximum longitudinal load determining of a shell is developed, provided that the requirements of local stability loss are fulfilled. Originality. The adaptation of one of the methods of "soft computations" - the theory of fuzzy sets to the problem of optimal design of a cylindrical orthotropic construction is carried out. Practical value.  Numerical calculations of the defuzzified fuzzy value of the longitudinal force are performed.
