Optimization of multiple objective gate assignments

This paper proposes a multiple objective e model to help airport authorities to efficiently and effectively solve gate assignment problems. The model is formulated as a multiple objective zero-one integer program. To efficiently solve large-seals problems in practice, we used the weighting method, the column generation approach, the simplex method and the branch-and-bound technique to develop a solution algorithm. To test how well the model may be applied in actual operations, a case study regarding the operation of Chiang Kai-Shek (CKS) Airport was performed. The results show that the model could be useful for actual operations. (C) 2001 Elsevier Science Ltd. All rights reserved.
