Abstract: Optimized combination occupies an important position in modern logistics service．At the present stage,the researchers of logistics Web services combination focuse on Web services general QoS indexes．It is difficult to meet the needs of service selection of specific areas．And the researchers focuse on economics and management,lack of service computing technology support．Aiming at these problems,model of domain QoS evaluation was built through domain QoS-aware to analyze the service combination．Logistics service provider selection,evolution and optimized combination can be researched using domain QoS-aware．Then the shortest path in combination schemes is computed by Dijkstra algorithm,namely combination service QoS values,which obtains domain QoS-aware logistics Web services optimized combination scheme,and predicts the development of domain QoS-aware service combination on modern logistics industry,which has certain theoretical and practical significance.

Key words: Logistics Web service,Domain QoS model,Service combination,Dijkstra algorithm
