Abstract :
Abstract. The critical and undeniable role of hubs in telecommunication and networking
brings about some precautions to be taken to protect networks against any disruption.
In this paper, a multi-objective model in a group of hub location problems, referred to
as protection models for survivable network design, is developed. In fact, this model is
a hub location problem that aims to maximize the potential
ow between the origin and
destination node pairs in the network, which has the minimum potential
ow among all
O-D pairs, including multiple assignment and back-up routes. In addition, it concerns the
xed cost of installation of the hub facilities. A fuzzy goal programming method is applied
to solve the model. Dierent scenarios are implemented using Turkish data set and also
numerical experiments are presented to illustrate the advantages of the proposed model
in some aspects, compared to previous models. The results can give useful insights into
telecommunication network design.
