Price-directive decomposition applied to routing in telecommunication networks

Article Abstract:

The telecommunication network design problem is analyzed to examine the level of transmission network. A heuristic strategy is developed to solve the combined routing-grouping problem, where the grouping one is solved by a heuristic method. The routing problem is formulated taking into account reliability limitations, supplementary circuits requirements and a piecewise linear objective function is used to consider the effect of the grouping. This last model is solved by a price-directive decomposition process which enables the solution of real networks employing an exact method.

Design of partially survivable networks for cellular telecommunication systems

Article Abstract:

A mathematical model that aids the design and optimization of cellular networks that connect cells to the mobile telephone switching office was developed. The proposed model shows a fast, accurate and easy way to implement a heuristic solution that was formulated using Lagrangian relaxation. This has resulted in the design of partially survivable networks with self-healing ring technology for cellular telecommunication systems.
