Multimodal Transportation p-hub Location Routing Problem with Simultaneous Pick-ups and Deliveries

摘要: Centralizing and using proper transportation facilities cut down costs traffic. Hub concentrate on flows to cause economic advantage of scale multimodal helps use the another transporter. A distinctive feature this paper is proposing a new mathematical formulation for three-stage p-hub location routing problem with simultaneous pick-ups deliveries time. few studies have been devoted problem; however, many people are still suffering from problems commuting in crowded cities. The proposed controlled tumult each node by indirect fixed cost. Node-to-node traveling cost was followed vehicle between nodes hub. couple datasets were solved small medium scales GAMS software. But, large-scale instances, meta-heuristic algorithm proposed. To validate model, used results demonstrated performance suitability algorithm.
