| Abstract: | To illustrate the relationships between the performance of service and workflow,concepts of service and service-oriented workflow were defined.Characteristics and operation mechanism of service-oriented workflow were explained with an example.Then,a service-oriented workflow performance evaluation model was put forward,which combined the performances of strategic layer,business layer,service layer and IT layer.Key Performance Indicators(KPI) and their formal representations corresponding to each layer were also described,and then the concept of correlation was introduced.Finally,the improved Analytic Hierarchy Process(AHP) was explicated to calculate the correlation between different KPIs and to select the most suitable services. |
