Services integration monitor for collaborative workflow management

Collaborative workflow management systems in logistic companies require strong information systems and computer network support. These IT integration requirements have expanded considerably with the advent of e-business; utilizing Web services and partner to partner e-commerce. This paper deals with change management of collaborative workflow in such consortia and proposes architecture for synchronization and monitoring of these services where existing workflow systems are adapted to the changes requested by management. This paper describes conceptual framework of the services monitor which is used to monitor and edit changes resulting in new collaborative workflows.

Coloured Petrinet for flexible business workflow modelling

Petrinet diagrams are a recognized form of modelling real time systems and have been included in the list of UML techniques for modelling the dynamic aspects of object oriented systems. In this paper, we explain how workflow techniques can be used for developing models for larger independent systems. These chunks or independent systems which are part of the large systems are expressed through the use of worklets. This can then be used as the basis of modelling systems where timeliness is of importance. However, this requires extending workflow ideas to incorporate flexibility, handling of exceptions and adaptability. Extensions of the Petrinet diagrams are then proposed for expressing the models obtained from such workflow techniques.
