The Business Process Modeling Notation (BPMN) is a standard for modeling business processes in the early phases of systems development. Model verification is an important means to guarantee the trustiness of composite services. The verification of model, especially the model with strict time constraints, is a challenge in the field of trust composite services. Whether a model is trustworthy depends...
The execution of process-oriented composite services described with BPMN has become a hot research topic. In this paper, we present a decentralized execution engine for BPMN-based composite services, the basic idea of which is to make a BPMN model directly executable without converting to another executable model. An executable BPMN model named BPD is first defined. Second, a set of algorithms are...
