Nodes-set Mining of Express Logistics Network Based on the Key Player Problem-positive Model
Aiming at the problem of nodes-set mining in express logistics network,this paper con-structs DW-KPP-Pos(Directed Weighted-Key Players Problem-Positive)model based on KPP-Pos(Key Player Problem-Positive)and designs a heuristic algorithm to improve the efficiency of the model.The empirical analysis of China's urban express logistics network shows that:The DW-KPP-Pos model with heuristic algorithm can efficiently mine"Maximum spread seeds group"in express logistics network.Including Shanghai,Chongqing,Guangzhou,Beijing,Jinhua and Hong Kong;The comparison of measurement results suggest that the propagation efficiency of nodes-set K mined by DW-KPP-Pos model is 0.59％,0.88％and 6.19％higher than that of de-gree nodes-set Kdeg,PageRank nodes-set Kpag and betweenness centrality nodes-set Kbet respective-ly.In this paper,a new method of nodes-set mining considering maximum spread effect is pro-posed,which can provide technical support for the layout of express logistics infrastructure.
