Transit route and frequency design: Bi-level modeling and hybrid artificial bee colony algorithm approach

Szeto, W.Y.; Jiang, Y. - In: Transportation Research Part B: Methodological 67 (2014) C, pp. 235-263

This paper proposes a bi-level transit network design problem where the transit routes and frequency settings are determined simultaneously. The upper-level problem is formulated as a mixed integer non-linear program with the objective of minimizing the number of passenger transfers, and the...

Solving the p-hub Median Problem Under Intentional Disruptions Using Simulated Annealing

Parvaresh, F.; Golpayegany, S. Hashemi; Husseini, S. Moattar - In: Networks and Spatial Economics 13 (2013) 4, pp. 445-470

Hubs are special facilities designed to act as switching, transshipment and sorting points in various distribution systems. Since hub facilities concentrate and consolidate flows, disruptions at hubs could have large effects on the performance of a hub network. In this paper, we have formulated...
