领域QoS感知的物流Web服务优化组合研究

Research of Domain QoS-aware Logistics Web Services Optimized Combination

优化组合在现代物流服务中占据着重要的地位。现阶段的物流Web服务组合研究多侧重于Web服务通用的QoS指标评价,难以满足特定领域的服务选择需求,并且多集中于经济学、管理学方面,缺乏服务计算技术的支撑。针对上述问题,从服务组合的角度通过领域QoS感知的方法构建了领域QoS评价模型来研究物流服务商的选择、进化以及最终的优化组合,然后运用Dijkstra算法计算出组合方案的最短路径,即组合服务的QoS值,从而获得领域QoS感知的物流Web服务较优化的组合方案,并预测领域QoS感知的服务组合,这对现代物流业的发展具有一定的理论和现实意义。

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.
