情景感知的物流Web服務(wù)動(dòng)態(tài)優(yōu)化組合研究
[Abstract]:Through large-scale integration of resources, the fourth party logistics service can combine excellent logistics services in the field, and provide users with the best combination of technology, warehousing, transportation services and other logistics services, so as to realize the low cost of logistics services. High efficiency, real-time operation. However, how to efficiently and dynamically construct a reliable logistics service combination to meet the needs of users' service quality is a key problem urgently needed to be solved by the fourth party logistics service providers. To solve this problem, a scenario aware dynamic composition method for logistics Web services is proposed. Firstly, based on the improved genetic algorithm, the global QoS constraints proposed by users are decomposed into local QoS constraints. Thus, the global optimization problem of logistics Web service composition perceived by QoS is transformed into a local optimal service selection problem, and then, in the process of logistics service process execution, according to the current key situation information, The optimal logistics service which can meet the local QoS constraints is selected. Finally, the feasibility and effectiveness of the proposed method are verified by experiments.
