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.
