【摘要】：針對鐵路客運網的客流分配問題,以鐵路列車開行方案為基礎,由各OD間多條旅客出行路徑構建鐵路客運網.采用廣義的旅行費用作為旅客出行路徑綜合總阻抗的度量,考慮不同鐵路線區(qū)間客流輸送能力和旅客出行路徑綜合總阻抗,提出不同鐵路線區(qū)間客流輸送能力飽和熵與旅客出行路徑綜合總阻抗熵等新概念.建立了以OD客流量守恒、旅客換乘次數限制以及客流量非負限制為約束條件,鐵路旅客輸送能力與旅客出行需求盡可能匹配的客流分配優(yōu)化模型.根據區(qū)間客流輸送能力和旅客出行路徑綜合總阻抗在實際問題中的重要程度,提出了基于組合熵優(yōu)化的客流分配迭代優(yōu)化求解算法.算例表明,利用該客流分配模型和算法能夠得到更有效更細致的不同出行路徑的鐵路客流分配方案.
[Abstract]:In order to solve the passenger flow distribution problem of railway passenger transport network, a railway passenger transport network is constructed on the basis of railway train operation scheme. The generalized travel cost is used as the measure of the total impedance of passenger travel path. Considering the capacity of passenger flow in different railway lines and the total impedance of passenger travel path, a new concept, such as saturation entropy of passenger flow transport capacity and total impedance entropy of passenger travel path in different railway lines, is proposed, and the conservation of OD passenger flow is established. The restrictions on the number of times of passenger transfer and the non-negative restrictions on passenger flow are the constraints. The optimal model of passenger flow distribution, which can match the passenger transport capacity and passenger travel demand as much as possible, is based on the importance of the capacity of passenger transport and the total impedance of passenger travel path in practical problems. An iterative optimization algorithm for passenger flow assignment based on combinatorial entropy optimization is proposed. An example shows that more efficient and detailed railway passenger flow assignment schemes with different travel paths can be obtained by using the model and algorithm.
