分析技术站调度员推算车流的思维过程。把车流推算问题看作商品交易行为,提出车流资源在编入出发列车时的虚拟价格概念及其确定方法,用来控制车流资源在车站的停留时间。提出不同等级出发列车的收益函数概念和确定原则,以保证等级高的出发列车可以优先被编入车流。以收益最大为目标,保证计划要求固定编组的列车可以满轴正点发车,以此构造出计算机自动配流的计算模型。对配流搜索空间进行预处理,设计有针对性的遗传算子、操作规则和染色体表示方法,应用遗传算法求解模型,得到满意解。
Analysis technology station dispatcher calculate the flow of thinking process. The calculation of the traffic flow is regarded as the commodity trading behavior. The concept of the virtual price of the traffic flow in the starting train and the method of determining the virtual price are put forward to control the residence time of the traffic flow in the station. The concept and principle of revenue function of different grades of departure trains are proposed so as to ensure that the starting trains with high grade can be preferentially incorporated into the traffic flow. The goal of maximizing profit is to ensure that the plan calls for a fixed group of trains to start at a full-scale positive point so as to construct a computational model of automatic distribution of computers. Preprocessing the distribution search space, designing targeted genetic operators, operation rules and chromosome representation methods, and applying genetic algorithm to solve the model to obtain satisfactory solutions.
