A general assumption in the reliable network design problem is that probability distributions of the sources of uncertainty are known. However, in reality, this distribution may be unavailable as we may have no (insufficient) data to calibrate the distribution. In this paper, we relax this assumption and present two robust alpha reliable network design models under distribution-free demand by adopting...
The urban multimodal transport system is a regular pattern of superposition and compound of different transport modes such as car, bus and bike. In this paper, the structure of such system is fully analyzed and a super-network topology model is proposed to describe it. The traveler's combined choice behaviors (including mode choice and route choice) are then analyzed. Accordingly, the generalized...
This paper is focus on the parameters settings using genetic algorithm to solve continuous network design problems (CNDP). The CNDP is formulated as a bi-level programming model. The sensitive analyses method, one-at-a-time designs, is used to analyze the effects of parameters. The analyses demonstrated that the setting of population size has clear effects to the solution; the effects of crossover...
