基于半定规划的鲁棒交通均衡模型

摘要

假定交通需求和交通供给属于一个球集合，基于这个假设，建立鲁棒用户均衡模型的极小化问题和相应的鲁棒对应模型，并将鲁棒对用模型松弛为半定规划模型。最后采用一个数值算例验证了说提出模型的有效性。%In this paper, assuming that the supply and demand of transportation belonged in a ball set, we studied the minimization problem of the robust user equilibrium model and the corresponding robust correspondence model, reduced the correspondence model into a semi-definite programming model, and at the end, through a numerical example, demonstrated the effectiveness of the model proposed.
