Service Oriented Architecture and Web Services provide an integration infrastructure for service workflow composition and execution. Many planning techniques can be facilitated to construct the service workflow at a building phase (planning), however, it is difficult and challenging to maintain the qualities of service workflow at execution phase, as the delayed response time, the limited throu...

With increasingly widespread adoption of workflow technology as a standard solution to business process management, much effort is put on designing appropriate workflow models. The reuse of existing models has been recently suggested to support more efficient workflow design, which requires the storage, search and composition of workflow models. In this paper, we propose a new framework of work...

XML Process Definition Language (XPDL) is the language proposed by the Workflow Management Coalition (WfMC) to interchange process definitions between different workflow products. The goal of XPDL is to provide a Lingua Franca for the workflow domain allowing for the import and export process definitions between a variety of tools ranging from workflow management systems to modeling and simulat...

In this paper, we propose a new failure-recovery model for workflow management systems (WfMSs). This model is supported with a new language, called the workflow failure-handling (WfFH) language, which allows the workflow designer to write programs so that s/he can use data-flow analysis technology to guide the failure recovery in workflow execution. With the WfFH language, the computation of th...

However, only scant research attention has been paid to formal workflow design methodologies. As a result, existing design methods in business process management remain a manual and...

Collaborative applications such as workflow management systems separate between a process model and an organizational model. While the process modeling capabilities of current workflow management systems are at a high level, the organizational meta models provided by these systems are very often at a very elementary level. Moreover, most systems fail to provide means to integrate non-human acto...

The paper firstly analyzes the characteristic of existing workflow applications and proposes cloud workflow layered model and design method based on the current major cloud computing trends. Considering the features on the cloud workflow system in distributed heterogeneous environment, the paper proposes a brief introduction to approach to cloud workflow system. Next, three deployment models of...
