Risk-Averse Stochastic User Equilibrium on Uncertain Transportation Networks
Wencheng Bao, Chrysafis Vogiatzis, Eleftheria Kontou
Travel times in transportation networks are uncertain and exhibit right-skewed distributions with long tails under weather and incident disruptions. The current challenge is that e…
A Robust Optimization Framework for Two-Echelon Vehicle and UAV Routing for Post-Disaster Humanitarian Logistics Operations
Tasnim Ibn Faiz, Chrysafis Vogiatzis, Md. Noor-E-Alam
Providing first aid and other supplies (e.g., epi-pens, medical supplies, dry food, water) during and after a disaster is always challenging. The complexity of these operations inc…
Evacuation Route Planning for Alternative Fuel Vehicles
Denissa Sari Darmawi Purba, Eleftheria Kontou, Chrysafis Vogiatzis
As the number of adopted alternative fuel vehicles increases, it is crucial for communities (especially those that are susceptible to hazards) to make evacuation plans that account…
Computational Approaches for Solving Two-Echelon Vehicle and UAV Routing Problems for Post-Disaster Humanitarian Operations
Tasnim Ibn Faiz, Chrysafis Vogiatzis, Md. Noor-E-Alam
Humanitarian logistics service providers have two major responsibilities immediately after a disaster: locating trapped people and routing aid to them. These difficult operations a…
A Column Generation Algorithm for Vehicle Scheduling and Routing Problems
Tasnim Ibn Faiz, Chrysafis Vogiatzis, Md. Noor-E-Alam
During natural or anthropogenic disasters, humanitarian organizations face a series of time-sensitive tasks. One of the tasks involves picking up critical resources (e.g., first ai…
A Primal-Dual Interior Point Method for a Novel Type-2 Second Order Cone Optimization Problem
Md Sarowar Morshed, Chrysafis Vogiatzis, Md. Noor-E-Alam
In this paper, we define a new, special second order cone as a type- second order cone. We focus on the case of , which can be viewed as SOCO with an additional {\em compli…
