Airline Network: Critical Leg Assessment via Variation in Practical Capacity

This research to the best of our knowledge is the first to quantify airline network sustainability in the presence changeable capacity of legs and alternative flights. In this article we try to recognize critical legs via changing practical capacity of airline network components. We try to assess the behavior of legs and network via variation of leg capacities while proposing a new leg cost function, also we demonstrate how to capture the robustness of airline network in the case of variable legs represented by decreasing and increasing capacities. We are using Relative Total Cost indices to assess airline network sustainability in the case of behavior associated with User–Optimization. In this article from different point of view, passenger’s rout preference behaviors are the main subject. Numerical case study is presented for illustration purposes. 
