Abstract

The purpose of this study is to develop an optimization method of maintenance planning of bridges for the asset management. It is realistically difficult to keep the safety of all bridges within a limited budget. Furthermore, the increase of the number of bridges treated in an optimization significantly increases the number of combination of solution candidates and the difficulty of optimization. Because an optimization of maintenance planning for multiple bridges is effective to decrease an annual cost, it is necessary to overcome this problem. In this paper, an attempt is made to propose a method making optimal plans in response to various objectives such as the cost saving, the improvement of safety and the adaptation to uncertainties. This method improves the flexibility of plan against the change of schedule by basing on the preventive maintenance. In the proposed method, various candidates of plan for each bridge are created in consideration of the preventive maintenance. Then, a combination of candidates corresponding to the purpose of planning is searched. A numerical experiment was presented to demonstrate that the proposed method could develop an optimal plan based on a safety level different from bridge to bridge.
