The incomplete hub-covering location problem considering imprecise location of demands

Facility location is a prime decision to be made in many organizations around the globe. thehub location problem is one of the main variants of the facility location problem, with applications intelecommunications, the airline industry, and etc. in this paper, we deal with an incomplete hub-coveringnetwork design problem, where the exact locations of demands are unknown and are estimated as fuzzyvariables. an earlier model in the hub location literature has been modified to address the uncertainty inthe problem. in order to solve this problem, an efficient simulation-embedded variable neighborhoodsearch (vns) has been designed and its performance has been validated using the well-known cabdataset.
