The dynamic models considered in this work, contain at the same time as the equations describing dynamics of indicators in continuous time on a final interval, and the equations with discrete time, characteristic for econometric models. For the specified class of systems statements of tasks as tasks about approachibility of preset values of indicators, in a form allowing effective research with use of modern computer technologies are given. Resolvability of the redefined of tasks in a case when approximate performance of boundary conditions is allowed is investigated .
