This paper aims to determine the optimal migrating route for refugees. Firstly, we develop a Secondary Fuzzy Evaluation Model(SFEM) to evaluate the metrics of refugee crises and allocate the refugees of six routes. Eleven factors are chosen as the primary fac- tors of SFEM such as the number of refugees, the security of routes, the types of transportation and so on. We apply variation coefficient weight method to reduce the subjective influence. Secondly, we establish graph theory model and change the issue of optimal removement into multistage deci- sion. The dynamic programming algorithm is used to solve it. At last, we add one stage in multi- stage decision a...
