This paper presents an optimization modeling technique to develop an evacuation plan for transit-dependent residents in the event of natural disaster such as the hurricane. The transit evacuation operation is formulated as a location-routing problem (LRP) with uncertain demands. The objective of this study is set to minimize the total evacuation time. The LRP problem identifies the optimal serving...
This paper focuses on the mixed transportation network design problem. A bi-level programming model, constrained by investment budget, is developed to minimize the total impedance of transportation network. The immune clone annealing algorithm, which is designed by combining annealing tactic of simulated annealing algorithm and immune clone algorithm, is introduced to solve the proposed bi-level model...
This study focuses on the logistics center location and allocation problem under uncertain environment. On the basis of the stochastic optimization model, a robust optimization model using the formation of regret model is proposed. Then, the relations among the robust optimization model, stochastic optimization model, and deterministic optimization model are analyzed, and two algorithms, enumeration...
For discussing the impact of congestion pricing on travel behaviors of residents, a disaggregated modal-split model considering pricing is formulated, and based on it, the traveler's perceived expectation utility function is built. Through a case study, the serviceability of this model is tested, and the sustainability of the impact of congestion pricing on the modal-split proportion is analyzed....
