ABSTRACT A Hierarchical Optimization and Clustering for Large Scale Disaster ReliefOnur Demir Yeditepe University. Istanbul, Turkey, email@example.com Linet Ozdamar Yeditepe University. Istanbul, Turkey, firstname.lastname@example.org
We describe a hierarchical cluster and route procedure (HOGCR) for coordinating vehicle routing in large-scale post-disaster distribution and evacuation activities. The HOGCR is a multi-level clustering algorithm that groups demand nodes into smaller clusters at each planning level, enabling the optimal solution of cluster routing problems. The routing problems are represented as capacitated network of models that are solved optimally and independently by CPLEX on a parallel computing platform. The HOGCR preserves the consistency among parent and child cluster solutions obtained at consecutive levels. We assess the performance of the algorithm by using large scale scenarios and nd satisfactory results.
