We propose an exception handling mechanism, based on techniques adopted in programming languages, for modifying at run-time the structure of a workflow. ...
Scientific workflow systems often operate in highly unreliable, heterogeneous and dynamic environments, and have accordingly incorporated different fault tolerance techniques. ...
In case of exception signalling, the descendants only have to signal it and the workflow node must be aware of handling it. ...

Unexpected exceptions in WfMS are situations not predicted during the design phase. Human involvement in handling this type of exceptions has been recognized to be a crucial factor. ...
We developed a framework to support the user in handling these situations by redesigning the flow, ad hoc executing the affected tasks, and manipulating engine status. ...
Some other studies have proposed the adoption of dynamic and adaptive workflow systems to react to exceptions during workflow execution. ...
