The governments of many communities have been trying to create their bridge maintenance planning. Generally their economic conditions are not good, the low maintenance costs and the smooth annual expenditure are required. For these requirements, the good approximation of the maintenance costs corresponding to the members and the materials of bridges are necessary. And also the real deterioration curves of the members of bridges are required. Some better models of these items are proposed in this paper with the improved GA process and make it possible to formulate the realistic BMS optimization problem. 300 really existed bridges problems are solved and show the effectiveness of the proposed optimization system.
