A method of representation and optimization of
hierarchical processing system with variable structure is
presented. The set of feasible structures for such class of
systems is defined and the representation of this set is
constructed. It is shown that the given choice of variable
parameters and the statement of the optimization problem
as a double minimum problem enable to construct
methods for finding a global optimum of total loss
function and select the corresponding structure. The
approach is given in terms of graph theory, convex
analysis and integer programming.
