| Abstract: | The provision of guaranteed QoS is critical to the success of Web services in business domains.Thus,how to make the composite Web services meet users' QoS requirement becomes a hot issue in the research field.This paper proposes a quality model,which takes into consideration three aspects: the service level QoS,the domain level QoS and the relation QoS of business.An optimized algorithm is presented to dynamically select the maximum path based on bidirectional dynamic programming. |
