Model and Algorithm of Discrete Network Design Problem under OD Demand Uncertainty

Abstract

Supposed OD demand elements as stochastic variables,the framework of discrete network design under OD demand uncertainty was presented based on stochastic bi-level programming and means-variance model.For the characteristic of discrete transport network design model under stochastic demand,Monte Carlo simulation algorithm and genetic algorithm were integrated to solve the problem effectively.Numerical results on Sioux Falls network indicates that the presented model and algorithm can be used in medium scale network well.
