Abstract

Besides employed for integrating heterogeneous applications and information systems inside individual organization, workflow technology has been brought into web-based and cross-organizational business applications, which makes the issues of temporal logic more and more important. Taking advantage of the application paradigm of web service, a general paradigm of service computing is discussed underlying collaborative operation. Furthermore, a temporal logic-based model is presented for piloting service invoking through QoS-oriented time constraint analysis. Supervised with the time model, a certificate-driven workflow application paradigm based on service computing is discussed under grid environment in form of virtual organization. The conclusion is presented at last.
