Abstract

In most past studies on Hub Location Problem (HLP), failure probability is limited to a constant value; however, in reality, it depends on various factors including natural disasters such as floods and earthquakes, commodity ow, institutional elements (strikes), etc. This paper looks into the problem of the hub network design through a new model. The problem is to maximize network Reliability and minimize the total routing cost simultaneously. In order to provide a more realistic model, the hub's failure probabilities were considered as a function of the hub's incoming traffic. Reserve hub elements were also taken into account in the model with the aim of increasing network Reliability. To solve the model, a Non-dominated Sorting Genetic Algorithm (NSGA-II) was presented. The parameters of the algorithm were tuned using Taguchi method. The proposed solution was then carried out in a case study where the results confirmed the acceptable performance of the model; moreover, sensitivity analysis was performed in order to describe the effects of critical parameters on objective functions.
