We consider a problem of optimal allocation of a homogeneous resource in spatially distributed systems such as communication networks, where both utilities of consumers and network expenses must be taken into account. This approach leads to a two-objective optimization problem, which involves non-differentiable functions whose values are computed algorithmically. We propose several approaches to define a solution and to construct corresponding solution methods for such problems. In particular, new subgradient methods for non-differentiable Pareto optimization problems are suggested. Their work is illustrated by computational results on test problems. |
