HLP (hub location problem) tries to find locations of hubfacilities and assignment of nodes to extended facilities.Hubs are very crucial and their inaccessibility impresses onnetwork whole levels. In this paper we are making effort toeither maximize the average reliability or minimize totalcost. To model and solve the problem, the fuzzymulti-objective programming approach has been presented.Eventually, a set of test problems are presented and thenumerical consequences are analyzed and we inspectedthem by plotting.
