摘要
铁路调度日(班)计划与货运作业是铁路运输生产经营中两个关键组成部分,它们之间存在着密切的关系.为推动铁路货运高质量发展,从调度日(班)计划与货运作业的关系出发,提出一种基于数字孪生的铁路货运装卸车作业流程仿真方案,充分利用计划、货运作业等相关数据,构建相应的铁路货运装卸车作业流程模型,通过仿真工具进行仿真,生成货运作业数字孪生结果,并利用机器学习优化模型,提高货运作业仿真预测结果的准确性.该仿真方案可应用于顺向推演模拟、阶段作业研判和逆向推演研判等场景,经试验验证,提出的方案和应用场景能够有效提高生产组织效率.
Abstract
The railway dispatch daily(shift)planning and freight operations are two key components of railway transportation production and operation,closely intertwined with each other.To advance the high-quality development of railway freight transportation,this paper proposes a simulation solution based on digital twin for railway freight loading and unloading operations,starting from the relationship between the dis-patch daily(shift)planning and freight operations.By fully utilizing relevant data such as plans and freight operations,a corresponding railway freight loading and unloading operation process model is con-structed,and the simulation tool is used for simulation to generate a digital twin result of freight opera-tions,moreover,machine learning is used to optimize the model to improve the accuracy of freight opera-tions simulation prediction results.This simulation solution can be applied to scenarios such as forward de-duction simulation,stage operation judgment,and reverse deduction judgment.The test verifies that the proposed scheme and application scenarios can effectively improve production organization efficiency.
