Pei Zhang · Jisuanji gongcheng yu sheji · 2011
To effectively utilize the atomic services with the same functions and different dynamic QoS in system,it needs to realize the atomic services run-time binding according to their QoS.A programmable way is given to express the QoS of atomic services by using service operations,then the rationality and validity is analyzed,the user QoS preference computing service is presented to generate and execute the QoS computing model according to the preference of the user,and a pattern with services orchestration to realize the run-time binding;last based on WS-BPEL [1](web services business process execution language) show an example to validate that the approach can realize the run-time binding of atomic services which caters to the preference of the user.
