Hoai Pham Thi, Hoai An Le Thi, Canh Nam Nguyen, An exact approach for solving the supplier selection problem in multi-service outsourcing

Abstract: We study the supplier selection problem in multiservice outsourcing (MSO) that has been modeled by Feng et al. [11] (2011). This model is indeed in the class of multiobjective combinatorial optimization (MOCO) problems. An heuristic decision method was proposed by Feng et al. [11] as well. However, to the best of our knowledge, no exact approach was explored for this problem so far. Hence, inspired by the recent developments on solving MOCO problems, we propose in this paper an exact algorithm based on polyblock approach for generating all nondominated points of MSO problems. Stack policies are also analyzed, pointing out their performance effectiveness by means of the results of computational experience.
