Summary:This study focuses on the optimization method of bridge management system. In many conventional cases, the plan involved in the BMS has been handled with a deterministic approach using the LCC as the objective and the year of repair for each member as design variables. However, this formulation involves many combinations of design variables, and does not increase the number of bridges for which effective design solutions can be obtained. While the authors used this formulation, effective solutions were obtained for only around ten bridges at most. From such a viewpoint, the conventional formulation of occasional repairs is not considered practical. In this study, another formulation was made using the inspection intervals of each bridge and the degree of soundness of members to be repaired as design variables.
