| Abstract: | In this paper, by using fuzzy random variables as the basic variables, the dynamic fuzzy random reliability of existing structures is defined. The maintenance decision criteria of existing structures are established on the basis of the order relations among fuzzy random variables. By using the extension principle of fuzzy sets, the functional relation between the dynamic fuzzy random reliability and fuzzy maintenance cost of existing structures is built. Finally, by the mathematical methods of structural fuzzy random optimization1,2], the structuralfuzzy random optimization models of maintenance scheme are built, the calculation methods of preventive and corrective maintenance scheme are given and the optimal solutions of the correspondent models are obtained. |
