Abstract
Purpose This study develops a new method that determines the location and the order of establishment of temporary logistics hubs (TLHs) taking account of multiple-objectives, multiple-attributes, and multiple-actors during disaster response. The research is motivated by the importance of TLHs and the complexity that surrounds its establishment. Design/methodology/approach A multi-period multi-objective mathematical model is developed to determine the location of the TLHs and a fuzzy simple additive weighing under the group decision-making (GDM) condition to determine the order of establishment of TLHs. Findings The optimization results provide useful managerial insights for decision-makers by considering the trade-off between two non-commensurable objectives. Determining the order of establishment helps to efficiently allocate mobile storage units when they limited in numbers. Use of fuzzy approach to evaluate subjective attributes eases the overall decision-making process. Research limitations/implications In this study, decision-makers are considered to be homogeneous, which might not reflect reality. This study does not consider the stochastic nature of relief demand and thus assumes demand to be known. Practical implications The outcomes of this study are valuable to decision-makers for relief distribution planning when there are multiple objectives, numerous decision-makers, and several attributes. The proposed fuzzy simple additive weighing approach under GDM is especially useful during emergency situation because of its ability to take account of vagueness and imprecision inherent in decision-making. Originality/value A new method is proposed and implemented to determine the location and the order of establishment of TLHs considering multi-objective, multi-attribute, and multi-actor nature of decision making during disaster response. To the best of the authors’ knowledge, the multi-objective, multi-attribute, and multi-actor aspects of the TLH location proble
