Workflows have been successfully applied to express the decomposition of complex scientific applications. This has motivated many initiatives that have been developing scientific workflow tools. However the existing tools still lack adequate support to important aspects namely, decoupling the enactment engine from workflow tasks specification, decentralizing the control of workflow activities, ...

Inter-organisational workflow (IOW) is a natural scenario for MAS (multiagent system) technologies. In particular, MAS coordination infrastructures can work as a general-purpose support for WfMSs (workflow management systems): coordination artifacts can be specialised as workflow engines, encapsulating workflow rules expressed in terms of coordination laws. A network of inter-connected coordina...

The increased focus of companies on improving their operational efficiency has raised a demand for advanced systems to support the continuous monitoring and analysis of business activities. These business activities are typically automated into workflow applications which are modeled, implemented and executed by workflow management systems (WFMS). The monitoring and analysis solutions aim at gi...

Enforcement of global cooperation urges the rapid growth of cooperative work. As a typical application of it, cooperative editing is widely used in many fields gradually, especially in knowledge intensive application. Workflow is a kind of automation technology by predefined process rules and tasks. It can bring us clarity in process control and management, which are two important facets in coo...

Inter organizational workflow management systems play a very important role in executing business processes among business partners in a dynamic and timely manner. An inter organizational workflow management engine is used to model and control the execution of business processes involving a combination of manual an automated activities between organizations. Before delivering their product and ...

In paper-based workflow systems, signatures of individuals or groups of people have been used extensively for various purposes. Currently there are numerous studies on computerizing workflow systems. Also there are studies on implementing digital signatures in electronic media. But the diversified purposes of a signature in workflow makes a straight-forward implementation of digital signature s...

Currently, many software systems are developed in offices geographically distributed in different locations. Furthermore, it is also common for a software system development project contracting to different software houses. These contracted software development projects, very ojien, are further sub-contracted to some other software houses. These software development modes can be supported and m...
