Study on the Efficiency of Refugee Migration Based on Computer Quantitative Computing

Nowadays, a massive flow of refugees into Europe causes serious problems to the local people's life, economic development and social stability. All experts and scholars from various countries give advice to the European government. Therefore, this paper analyses a large quantity of refugee migration data specifically to improve the efficiency of refugee migration as far as possible not to threaten European countries' security situation. Firstly, A Comprehensive Evaluation Model is established to quantitatively measure the efficiency of the refugee migration process, combining with the Differential Equation model to describe the dynamic change characteristics of refugee migration process. Besides, this paper builds the Graph Theory model by labeling method and computer search to obtain the maximum permissible refugee flow and refugee migration route. Finally, we simulate the realistic situation of non-governmental organizations, and put forward scientific and reasonable recommendations.
