中文摘要：

通过对某大规模物流基地产品出库的间隔分布进行分析,发现物流基地的各个仓库的钢材产品出库均具有阵发特征,出库时间间隔服从幂律分布,且幂指数约为2.5,与Barabasi和Vazquez所总结的两大类幂指数不同。对造成物流系统的阵发特征的机理进行分析,发现阵发特征可以采用群体行为过程中任务的优先级来解释,而优先级主要由节假日与内部作业调度造成。通过对活跃个体的出库行为进行研究,发现物流系统中的个体行为不具有阵发特征。

英文摘要：

This paper proposed that the steel products warehouse-out of all the warehouses in the large-scale logistics base had burst feature and the warehouse-out inter-event time followed the power-law distribution with exponents closed to α = 2. 5 which differs from the two classical Barabasi and Vazquez models,by analyzing the warehouse-out inter-event time distribution of the products in one certain large-scale logistics base. It discussed the burst features and mechanism of logistics system and found the burst features could be explained by the priority in population behaviors,which was a consequence of the festivals and holidays and interior task scheduling. Finally,this paper studied the warehouse-out behavior of active individual,and found that individual behavior didn＇t have the burst feature in logistics system.
