-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.

Logistics activities require strong information systems and computer support. This IT support requirements has expanded with the advent of ecommerce; utilizing B2B (Business to Business) and P2P (Partner to Partner) ecommerce. There has been an increasing tendency to set up consortia that represent several players in a given field collaborating with one another to form a large logistics consortium in order to form one organization to compete with larger competitors and/or extend beyond their region of operation. This paper deals with the management of collaborative workflow changes in such consortia and the adaptation of these changes to existing workflow systems. We also discuss issues of adaptation to new systems, workflow mining techniques for adaptation and a proposed prototype to capture the meta-data to implement the workflow system.

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 ecommerce.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.

Collaborative workflow management systems in logistic companies require strong information systems and computer support. These IT integration requirements have expanded considerably with the advent of ebusiness; utilizing web services for B2B (Business to Business) and P2P (Partner to Partner) e-commerce. This paper proposes service oriented model driven architecture for dynamic workflow changes and strategy for implementation of these changes by isolation of services and business processes where by existing workflow systems can easily incorporate and integrate the changes following a step by step process replacement synchronization in workflow. This paper will also describe conceptual framework for prototype implementation resulting in dynamic collaborative workflow management.

Whether the economy is strong or weak, competition is fierce. The need for business change to maintain a competitive edge comes faster in this rough business environment causing the business process model to get more dynamic and complex. However, one has to manage it so the efficiency of business processes are maximised. This paper develops a modelling approach for dynamic business processes, defining exceptions and enabling business strategies to be captured vigorously while simultaneously allowing changes to be handled. We introduce the MAO workflow model, and we propose the automation of workflow components using MDA
