An integrated algorithm for QoS-aware logistics service composition

With the rapid development of the logistics industry, there are more and more logistics services on the Internet platforms. However, a single atomic service has not been able to meet the complex needs of users. So the service composition in large-scale environment is very meaningful. In this paper, we propose a web service composition approach for logistics, which consists of three main steps: 1) Using semantic model to automatically generate the service matching graph to meet the request; 2) An algorithm for computing the optimal QoS based on the shortest path of Dijkstra; 3) Based on the previous semantic matching mechanism and the optimal aggregate QoS value as the constraint condition, the redundant service in the composited graph is removed; This method can be used for automatically discover and composite a minimum number of services from a large number of services that satisfies both multiple QoS criteria and semantic matching between logistics services.
