针对区域综合运输通道客运交通供给和需求量大,出行方式多,各出行方式竞争激烈的特点.为了避免各出行方式之间存在恶性竞争,扰乱运输市场的正常秩序,建立了区域综合运输通道协同的多目标非线性规划数学模型.模型建立在出行者对交通方式的选择遵守效用极大化原理的基础上,系统目标为各出行方式的供给量与需量相适应.采用模糊折中算法将多目标转化为单目标,同时采用广义牛顿法对非线性规划问题进行求解,为了避免求得的解为局部最优解,提出了随机从不同的初始点进行寻优,尔后对各个结果进行比较,从中选出较优者作为全局最优解.该方法极大的提高了所求解为全局最优解的可靠性.最后通过算例证明了模型的正确性和可行性.
In order to avoid the vicious competition between different modes of travel and disrupt the normal order of the transport market, the regional comprehensive transport corridor has the characteristics of large supply and demand for passenger transport, large number of travel modes and fierce competition among modes of travel. Based on multi-objective nonlinear programming mathematical model.The model is based on the traveler's choice of mode of transportation to comply with the principle of utility maximization, the system goal is to adapt the supply and demand of each mode of travel.Using the fuzzy compromise algorithm In order to avoid the solution of the local optimal solution, a new optimization method based on the generalized Newton method is proposed to solve the nonlinear programming problem. , The better one is selected as the global optimal solution.The method greatly improves the reliability of the global optimal solution.Finally, an example is given to demonstrate the correctness and feasibility of the model.
