【摘要】：公(铁)路土石方工程是公路及铁路工程中的一项重要工作,施工过程中的机械配置的合理性将直接影响整个工程的施工进度及经济费用。因此,对施工机械进行优化配置研究,不仅具有良好的理论意义,而且有着一定的实际意义。本文在前人研究基础上,以机械化作业机群系统为对象,构建了土石方装运机械配置方案优化模型。该系统可划分为两个子系统：土石方装运子系统和机械配置方案评价子系统。具体研究工作及成果如下： (1)在分析公(铁)路土石方装运系统的特点基础上,建立了基于排队论的土石方装运系统过程仿真模型,通过仿真及优化计算得出机械配置方案的总费用和总工期； (2)利用多目标优化理论构建时间-费用评价函数,通过评价函数计算出方案的评价值； (3)利用多目标粒子群算法对模型进行求解,通过算例验证了该算法具有良好的优化效果,并且能够提供多种优化配置方案。 (4)在分析Matlab与Visual C++各自特点的基础上,利用Matlab强大的数值处理分析能力和Visual C++面向对象的可视化编程功能,实现两者的联合编程,提高了系统运行效率。
[Abstract]:The public (iron) road earthwork engineering is an important work in highway and railway engineering, reasonable mechanical configuration in the construction process will directly affect the construction schedule and cost of the whole project. Therefore, optimize the allocation of construction machinery, not only has the good meaning of theory, but also has a certain practical significance.
Based on previous studies, and taking mechanized operation cluster system as an example, the optimization model of earth and stone transportation machinery configuration scheme has been constructed. The system can be divided into two subsystems: the earth rock transportation subsystem and the mechanical configuration evaluation subsystem.
Specific research work and results are as follows:
(1) based on the analysis of the characteristics of the earthwork transportation system of the public (iron) road, a process simulation model based on queuing theory is established, and the total cost and the total duration of the scheme are obtained through simulation and optimization calculation.
(2) the time cost evaluation function is constructed by multi-objective optimization theory, and the evaluation value of the scheme is calculated by the evaluation function.
(3) the multi-objective particle swarm optimization algorithm is applied to solve the model. The example shows that the algorithm has good optimization results, and it can provide many kinds of optimal allocation schemes.
(4) on the basis of analyzing the characteristics of Matlab and Visual C++, we use Matlab's powerful numerical processing and analyzing ability and Visual C++ object-oriented visualization programming function to realize the joint programming between them, and improve the efficiency of the system.
