求解随机交通均衡问题的一种光滑样本均值逼近法

摘要

In this paper,we reformulate stochastic traffic equilibrium problem as stochastic nonlinear comple-mentarity problem. Then we propose the sample average approximation method for solving the stochastic non-linear complementarity problem. Finally the method is applied to a specific stochastic traffic equilibrium problem.Preliminary numerical results are given.%文章将随机交通均衡问题转化为随机非线性互补问题;给出求解随机非线性互补问题的样本均值逼近(SAA)法;最后将该方法应用于一类具体随机交通均衡问题,给出数值实验.
