A bi-objective hierarchical hub location model with facility failure

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