According to the arithmetic performance of a solver for executing the design, a problem scale corresponding to one path accommodation designing operation is set. Based on the set problem scale, a mathematical programming problem for minimizing the objective function is generated. An accommodation designing process is repeated on a plurality of paths until a solution to the mathematical programming problem is obtained by the solver, and all requested paths are completely designed.
