چکیده

Web services composition is the ability to integrate existing services to have value added services. Workflow-based services composition is one of the approaches proposed. eFlow is one of the Workflow-based service composition approaches. The approach is strong in providing a platform for adaptive and dynamic web services composition. However, it neglects the validation of the Quality of Services (QoS). This paper proposes an initial work to validate the QoS of web services composition. We propose an approach to transform eFlow to PetriNet. We also extend existing Petri-Net by introducing a new component with new firing rule. Our preliminary result is to show that formal validation techniques like Petri-Net are useful towards validating the QoS of e-services composition.

Towards Modeling and Simulating a Multi-party Negotiation Protocol with Colored Petri Nets

E-contracting, i.e., establishing and enacting electronic contracts, has become important because of technological advances (e.g., the availability of web services) and more open markets. However, the establishment of an e-contract is complicated and error prone. There are multiple negotiation styles ranging from auctions to bilateral bargaining. This paper provides an approach for modeling mul...
