A b s t r a c t . We study the practical stability of systems of ordinary differential equations depending on parameters for the numerical calculation of the stability regions of the set of initial conditions and parameters considered in the given structural form. This approach can signifi cantly extend the range of the investigated problems related to the problem of sensitivity.

Key words: practical stability, tolerances on the parameters, the perturbation parameter of the system.
