摘要: 结合车站自律机、联锁系统、客运站股道运用技术作业及其要求, 设计了基于分散自律控制原则的系统模型、功能与体系结构。运用现代排序理论, 构建了股道运用实时调整可控排序模型和耦合模型, 提出了基于合成分派规则的三步算法与股道运用通用启发式算法, 求解股道运用系列决策问题, 解决铁路行车及调车作业之间的干扰问题, 并开发了CTC条件下铁路客运站股道运用决策支持系统。分析结果表明: 合成分派规则的平均优化解明显优于基本分派规则的平均优化解, 合成分派规则EDD+FIFO获得的解最优; 实时调整时宜直接采用合成分派规则, 尤其是规则EDD+FIFO, 求解耦合问题时应综合考虑各种分派规则。可见, 系统的功能、性能和技术指标均能满足股道运用智能编制和实时调整的现实需求。Abstract: With station autonomy machine, interlocking system, various technological operations and their requirements of track utilization at railway passenger station, the system model, functions and structure were designed based on the principle of decentralized and self-regulated control. The real-time adjustment controllable scheduling model and coupled model of track utilization were constructed by utilizing modern scheduling theory. The three-step algorithm of synthesis dispatching rules and the general heuristic algorithm of track utilization were put forward to solve the series decision problems of track utilization and disturbance problems among technical and shunting operations. A decision support system of track utilization with centralized traffic control (CTC) at railway passenger stations was developed. Analysis result indicates that the means optimum solution of synthesis dispatching rules is much better than that of basic dispatching rules, and the synthesis dispatching rule EDD+FIFO can get the best solution. The synthesis dispatching rules, especially EDD+FIFO, should be adopted to make real-time adjustment plan, while various dispatching rules should be applied to solve track utilization coupled problem. So the system functions, performances and technical parameters can meet the practical needs for making track utilization plan and real-time adjustment plan at railway passenger station intelligently.
