| Abstract: |
In this study, an attempt is made to propose a method for flexible bridge maintenance plans against the modification of deterioration curve by using the multi-stage optimization. Both the minimization of cost and the maximization of structural soundness are important for the maintenance planning. Numerical experiments with 10 bridges were presented to demonstrate that solutions obtained by the proposed method were effective against the uncertainties involved in the financial circumstances and the deterioration prediction. |
