列车规划（也称为铁路调度）对任何铁路的成功都是一个非常重要的领域。通过列车规划，铁路管理者的目标是在尽可能使用低水平的资源（基础设施、铁路车辆和员工）的同时满足客户的需求。高效和有效的列车规划是使铁路网获得最佳性能的必要条件。本文作者的目的是，首先，分析用于制定列车计划的过程以及它们达到预期目标的程度，其次，调查选定的新的和创新的软件方法，这些方法可能对列车计划过程的有效性和/或效率产生重大影响。这些目标是通过一系列主要的定性研究方法来实现的，包括文献综述、访谈、参与者观察和案例研究，以了解这些过程和软件。关于列车规划过程的结论包括这些过程的复杂性如何阻碍其有效性，英国铁路私有化对这些过程的负面影响以及私有化铁路中列车规划目标的冲突性质。列车规划软件被发现不能充分支持列车规划者达到他们设定的目标。讨论了利用启发式方法生成时刻表的潜力，以及利用时刻表性能模拟来提高列车规划的有效性，并提出了进一步研究和开发的建议，以解决现有软件的局限性。
Train Planning (also known as railway scheduling) is an area of substantial importance to the success of any railway. Through train planning, railway managers aim to meet the needs of customers whilst using as low a level of resources (infrastructure, rolling stock and staff) as possible. Efficient and effective train planning is essential to get the best possible performance out of a railway network. The author of this thesis aims, firstly, to analyse the processes which are used to develop train plans and the extent to which they meet the objectives that they might be expected to meet and, secondly, to investigate selected new and innovative software approaches that might make a material difference to the effectiveness and/or efficiency of train planning processes. These aims are delivered using a range of primarily qualitative research methods, including literature reviews, interviews, participant observation and case studies, to understand these processes and software. Conclusions regarding train planning processes include how the complexity of these processes hinders their effectiveness, the negative impact of the privatisation of British Rail on these processes and the conflicting nature of objectives for train planning in the privatised railway. Train planning software is found not to adequately support train planners in meeting the objectives they are set. The potential for timetable generation using heuristics and for timetable performance simulation to improve the effectiveness of train planning are discussed and recommendations made for further research and development to address the limitations of the software currently available.
