Reliable multiple allocation hub location problem under disruptions.

Hubs play an important role in the network of many distribution systems. However, hubs can be disrupted due to various reasons, and such disruptions can lead to a substantial transportation cost increase. In this study, we investigate the reliable multiple allocation hub location problem with fixed cost considering multiple hub disruptions. We use multiple uncertainty sets to model the uncertainty of hub disruptions and propose a model based on the two-stage robust optimization approach. To solve the two-stage robust model, we develop an efficient exact solution method based on the column-and-constraint generation algorithm. Numerical examples from the CAB dataset confirm the effectiveness and efficiency of the proposed model and the solution algorithm. [ABSTRACT FROM AUTHOR]
