The problem of optimal design of rotationally symmetrical shells of uniform stability stiffened by ribs was discussed in the current paper. The structure was modelled in ANSYS software and solved by FEM method. The formulation of uniform local stability was successfully verified by the linear buckling solution. The optimization tasks were solved numerically using the modified Particle Swarm Optimization algorithm. The critical loading multiplier was increased by determining the optimal shape of the meridian, distribution of a wall thickness in a coat of shell and the placement of ribs inside the shell.
