摘要
根据道路管理者在项目决策过程中的决策心理,将项目优化分解为资金分配和项目分配两个相互影响又相互独立的过程,并由此建立了由资金分配模型和项目分配模型组成的项目优化模型的双层优化结构.利用动态规划和遗传算法对上述模型进行了有效的求解,结果显示,该模型及算法较好地弥补了传统数学优化法计算速度慢、计算结果不能指导实际工作的缺点.
The staging characteristics of the decision-making process was captured and used to divide the task of project scheduling and prioritization into two processes,namely,maintenance fund allocation and project prioritization.A bi-level program was then constructed to model the decision-making process.The techniques of dynamic programming and genetic algorithm were applied to solving the bi-level model and the deficits of conventional methods were overcome as illustrated in the applications.
