摘　　要：为了有效地进行铁轨养护维修促进铁路高效运营和维修成本的经济合理,设计了基于0-1整数非线性规划的铁轨维修作业模型,并基于分支定界算法对模型的有效性进行了仿真分析。模型以维修时间和地点为决策变量,以维修区段内的轨道几何状态TQI均值最小为目标,并考虑了多台养护机械协调作业的规划和单元区段的分类约束。分析结果表明,该方案相比于非优化规划算法能有效地降低轨道的不平顺性。In order to effectively perform the track maintenance,promote the efficient railway operation,and guarantee the reasonable maintenance costs,the track maintenance operation model based on 0-1 integral nonlinear planning was designed.The simulation analysis for model effectiveness is conducted based on branch-and-bound algorithm. The maintenance time and place of the model are used as the decision variables,and the minimum TQI mean value of track irregularity state in maintenance area is used as the objective. The planning of multiple maintenance machines coordinated operation and constraint classification of sections in each unit are considered. The analysis results show that,in comparison with the conventional non-optimal planning algorithm,the proposed scheme can effectively reduce the track′s irregularity performance.
