市域(郊)铁路周期式公交化列车运行图的计算机编制模型OA

Based on the characteristics of periodic,high density and regular bus-like service in suburban railway timetables and the need for operating express,local,and cross-line trains,this paper identifies critical issues in timetabling.Drawing on the periodic event scheduling problem(PESP)framework,it integrates rolling stock circulation and station technical operation schemes to establish a multi-objective integer programming model,aiming to minimize the total train travel time,the number of rolling stocks,and balance homogeneous train services.It designs an iterative solution algorithm for a phased timetable,alongside a model and algorithm for seamless full-day timetable splicing.Case studies on a planned suburban railway network demonstrate the effectiveness of the model in collaboratively optimizing train operation line layout,overtaking,turn-back,and cross-line operations for multi-line timetabling,and achieving smooth transitions during full-day timetable splicing.This provides a digital solution for the computer-aided timetabling of suburban railways.
