| Abstract(in English) | For combinational optimization problems, we have two approaches; the exact methods and the approximated methods. The exact methods may require lots of computation time to get the exact solution even though the algorithms try to reduce the searching space, while metaheuristics can obtain approximated solutions within reasonable computation time. This paper proposes a hybrid method based on the exact method and metaheuristics for mixed integer programming problems. We can control in our hybrid method the tradeoff between the quality of approximated solutions and the computation time by adjusting the ratio of decision variables to be determined by metaheuristics to the ones by the exact method. We apply our hybrid method to cyclic job-hop scheduling problems and computational experiment shows the effectiveness of our proposed method. |
