Abstract
We present a novel Web-based device workflow management engine (WDWME) that supports seamless control and coordination of hardware devices. With this workflow engine, a series of activities or workflows regarding hardware functionality or services can be rapidly created via drag and drop. A working Web-based workflow prototype has been developed as a proof of concept and tested using a device simulator to capture the task executions. In this work, a feature interaction detection engine (FIDE) is employed to validate the possible operation conflicts during the creation and pre-execution of a workflow. Additional justified-event-condition-action (JECA) rule and a case-based reasoning (CBR) are proposed as future work to enhance the system's exception handling capability.
