| 摘 要： | 应用遗传算法,基于动态可靠度的概念,以有限投资作为限制条件,以期望收益最大化为优化目标,在路网层次上对系统可靠度和后续使用期进行优化计算。以含有四条线路的公路网作为算例,分析了各种资金限值下最优可靠度与后续使用期,并指出在进行投资决策时,应考虑线路期望损失与收益的相对关系。

| Abstract: | Based on genetic algorithms and dynamic reliability, this paper gains the reasonable line system's reliability and working life under the limited fund and maximum profits in the level of road network. One example of road network is provided which include four line systems. This paper analyses the reasonable line system's reliability and working life under different limited fund. It is proved that the relation of line system's profit and damage should be considered in the fund distribution. |
