英文摘要：

For the multi-objective vehicle routing problem in emergency logistics distribution, this paper proposed an improved intelligent water drops algorithm for multi-objective routing programming scheduling of emergency materials. The main contents consist of four steps： a） constructed the disease spreading model in multiple areas based on Holling- Ⅱ function, b） data fusion to forecast the relief demand in multiple areas, c） built the multi-objective mathematical model with the minimum emergency logistics distribution time and cost, d）designed an.improved intelligent water drops algorithm for multi-objective emergency materials distribution path optimization. The results show that the established model and algorithm are effective and feasible, which can provide references for decision makers of emergency logistics management.
