【摘要】：现代有轨电车作为一种优秀的公共交通方式,近些年得到了快速发展。在我国诸多省市已经规划建设了规模庞大的有轨电车路网,随着运营系统的发展,车辆的检修调度工作趋于工作量巨大,信息复杂,一个针对车辆检修调度的信息系统能够为决策者提供行之有效的解决方案。目前国内已开通有轨电车的城市,大部分采用简单的信息管理系统,各部门使用独立的系统,无法做到信息的汇总和共享,仅仅是做简单的记录工作。检修计划的制定依然依靠人工计算,在车辆数增加和路况较复杂的情况下不能统筹全局,容易造成计划不合理,过度修或者欠修的情况,缺乏对整个车辆段日常工作流程的信息化方案。本文分析了有轨电车检修调度模式,得出目前我国宜采用预防修计划自动制定方法,将车辆段作业流程通过B/S结构实现,各个部门之间互相通信,提高检修效率,节约检修成本。首先根据目前有轨电车车辆检修状况,提出应参考车辆更新情况,实际工作需求实现信息化,不断提升车辆段内部各项工作效率,并保证生产安全。然后依据工作需求和功能需求,选择适宜的软件开发平台和开发环境,使用稳定高效的数据库管理工具,保障数据安全性和健壮性。基于选择的开发相关工具,设计系统主要功能模块,检修计划管理实现了一定时间段内检修计划安排表,通过该表选择需要检修的车辆,为其制定检修计划,安排入库检修,其中故障修为节约时间不需上报,直接下达到检修部门。提前根据专家经验知识库及修程修制,编写日检、双月检等修程的工作包内容,作为维修模式表,计划制定者可根据实际需求修改维修模式。车辆调度管理是安排车辆入库及出库方案,检修过程管理实现检修计划落实、车辆监控、检验工作、记录数据的功能,预警系统是为了提醒计划制定人员注意到期车辆和物料库存。对于系统的主要模块预防修计划管理,通过分析制定检修计划和执行的流程,考虑检修能力约束、运营模式约束、检修周期约束等条件,提出了尽力均衡每日的检修任务以避免集中修理,减少检修次数以提高车辆利用率的优化目标。使用基于“最大-最小蚁群系统”的算法求解问题的模型,该算法具有全局搜索效率较高的优点,能够有效地解决组合优化以及生产调度问题,将实际业务与模型紧密联系在一起。然后通过上海张江有轨电车的运营数据带入计算,得到两周时间内线路中9辆不完全相同运营里程车辆的预防修计划安排表,分析结果发现符合各项约束条件,且能实现优化的目标,验证了算法的合理性。最后根据需求设计开发出有轨电车车辆检修调度系统,符合模块的功能设计,实现了计算机制定检修计划,人工辅助制定保证容错性,准确划分各部门职责,互通数据方便业务流转,精确记录各项工作的数据,系统的设计推动了有轨电车车辆段信息化发展,在保证安全生产的基础上,提高段内工作效率,通过合理安排车辆检修节约了大量的人员、物料成本,为车辆段日常运营管理奠定了坚实的理论与技术基础。
[Abstract]:The modern tram as a public transportation outstanding, has been rapid development in recent years. In many provinces and cities in our country have been planning the construction of large-scale tram network, along with the development of operation system, maintenance scheduling of vehicles to the workload is huge, complex information, one for the vehicle maintenance scheduling information system to provide effective solutions for decision makers. China has now opened the tram in the city, most of the information management system, the system of each department use independently, can not do the information collecting and sharing, just do the recording work simple. Make the maintenance plan still rely on manual calculation, and road complex under the condition of the overall increase in the number of vehicles is not easy to cause, the plan is not reasonable, excessive repair or under repair, the lack of the whole vehicle in daily work The information process. This paper analyzes the tram maintenance scheduling mode, arrives at the conclusion that China should adopt preventive maintenance plan to develop automatic method, the depot operation process through the B/S structure, the mutual communication between the various departments, improve maintenance efficiency, save the maintenance cost. The first tram vehicle maintenance according to the current situation, put forward should the reference vehicle updates, the actual work needs to realize informatization, improve the working efficiency of vehicle interior, and ensure the safety of production. Then according to the work requirements and function requirements, selection of software development platform and development environment for the use of stable and efficient database management tools, data security and robustness. The development of related tools based on the design of the main function modules of the system, the maintenance plan management to achieve a certain period of time the maintenance scheduling table, through the table selection The need for maintenance of the vehicle, making maintenance plan for the arrangement, storage maintenance, fault repair time saving without reporting directly to the maintenance department in advance. According to the knowledge base of expert experience and maintenance system, prepare daily inspection, inspection and maintenance work or the contents of the package, as a maintenance mode, plan can modify maintenance mode according to the actual needs. The vehicle scheduling is arrange the warehouse entry and delivery plan, maintenance process management to achieve the maintenance plan implementation, vehicle monitoring, inspection, record data, early warning system is to remind the planners noted that vehicles and material inventory. The main modules of the system and preventive maintenance plan management. Through the analysis of maintenance planning and execution, including maintenance capacity constraints, operation mode constraints, maintenance cycle constraint conditions, put forward to the daily maintenance of any equilibrium In order to avoid centralized service repair, reduce maintenance times to improve the optimization of target vehicle utilization. Based on the use of "max min ant system algorithm to solve the problem of the model, the algorithm has the advantages of global search efficiency high, can effectively solve the combinatorial optimization and scheduling problems, the actual business model and closely linked together. And then through the Shanghai Zhangjiang tram operation data into the calculation, get two weeks in line 9 is not exactly the same operating mileage of vehicles and preventive maintenance schedules, analysis results show that fit the constraints, and can realize the goal of optimizing the rationality of the algorithm is verified. Finally, according to the demand of design and development a tram vehicle maintenance scheduling system with function module design, realization of a computer assisted maintenance planning, established to ensure fault tolerance, accurate classification The responsibilities of various departments, to facilitate business exchange of data transfer, accurate records of the work of the data, the design of the system has promoted the informationization development of tram depot, to ensure production safety, improve work efficiency period, through the reasonable arrangement of vehicle maintenance saves large amount of personnel, material cost, establishes theory and technology the solid foundation for the vehicle daily operations management.
