Abstract: In order to solve the problem of ASON restoration capacity assignment, the corresponding mathematical model was established, and a new optimization algorithm based on estimation of distribution algorithm was presented. Comparcel with other restoration capacity methods, this algorithm reduces the calculation work significantly, which facilitates the application of algorithm on projects. Simulation results show that the near global optimal solution can be easily obtwined and the solution is definitely satisfactory in engineering.
