QoS-based optimal selection approach for cloud service composition in manufacturing

To meet the individual needs of cloud services composition, the QoS evaluation method of the service composition considering logistics services was researched, and a cloud service description model was constructed. On this basis, related QoS metrics of cloud service were calculated. To make a comprehensive evaluation of the index value, a historical data based subjective and objective QoS metrics weights setting method was given. Finally, an auto parts process instance was used to verify, and the case study illustrates the feasibility and effectiveness of the method to evaluate QoS of service composition containing logistics services.
