摘要 为解决铁路工程技术接口施工时多主体、多任务、多工序协同度不高导致的停工、资源冲突等问题,从多目标协同优化的角度对铁路工程技术接口施工工序进行研究。从系统整体的角度出发,对各个接口任务进行全方位、全过程、全要素的动态协同管理,实现分布式资源的协同与共享。利用Pareto最优原理,基于NSGA-Ⅱs算法,建立不确定环境下技术接口工期-鲁棒性-资源的多目标均衡优化模型,求得一系列Pareto最优解集,实现各个目标的协调优化。以某铁路标段桥隧连接处为例,对其技术接口进行多目标优化分析,得到23个接口工序调度方案的最优解集,并结合接口实施的实际情况,对其工期、鲁棒性和资源的需求作出优化决策,为技术接口工序工期和资源的合理安排提供参考。 In order to solve the problems such as work stoppage and resource conflict caused by the low degree of synergy of multi-body,multi-task and multi-processes during the construction of technical interfaces in railway projects,this paper studied the construction processes of railway project technical interfaces from the perspective of multi-objective collaborative optimization.Firstly,from the perspective of the whole system,the dynamic collaborative management of all aspects,whole process and all elements of each interface task was carried out to realize the collaboration and sharing of distributed resources.Secondly,based on the Pareto optimality principle and NSGA-Ⅱs algorithm,a multi-objective equilibrium optimization model of technical interface schedule-robustness-resources was established under uncertain environment.A series of Pareto optimal solution sets were obtained to realize the coordination and optimization of each objective.Finally,based on the multi-objective optimization analysis of the technical interfaces of the bridge-tunnel connection of a railway section,the optimal solution sets of 23 interface process scheduling schemes were obtained,which were combined with the actual implementation of the interface construction to make optimal decisions on the duration,robustness and resource requirements,providing reference for the reasonable arrangement of the process duration and resources of technical interfaces.
