    Due to the evolutionary nature of the engineering design process it is necessary to provide support for version management. The version model should be provided with an integrity checking mechanism to assure the consistency of object versions with the design constraints. Managing integrity constraints is complex due to their evolving nature and raises a number of issues that need to be dealt with.... View full abstract»

    IP QoS is one of the core technologies of IP network. The mechanisms to achieve IP QoS could be sub bandwidth management (SBM), multiple protocols label switching (MPLS), IntServ, DiffServ and so on. But some of the above should be integrated for implementing completed IP QoS. At present, one of the most popular ideas is IntServ on the edge of network and DiffServ on the backbone. In this paper, w... View full abstract»

    Sharing data is an important aspect in distributed design environments and should be supported by an underlying system. Any synchronous access to data is conflict prone. Applying concurrency control and two phase commit are an option to be considered. But design processes also demand cooperation between the designers. Negotiation about actions on the product under design and the early exchange of ... View full abstract»

    Workflow technology provides a good way to mediate the flow of responsibility in a business process from person to person and from task to task. However, most current workflow systems are not able to do this very well. The main reasons are: (1) most activities of a workflow are executed asynchronously and respectively according to their workflow model, and cannot be executed synchronously; (2) ext...

    Workflow management techniques are aimed at supporting business processes across organizational boundaries. Current techniques lack the formal tools to model and analyze workflows on a large scale, and current WFMSs do not have the ability to react to the response of another WFMS dynamically. Using Petri nets as the modeling tool, we present the concept of a standard workflow structure, and a set ... View full abstract»

    XRL (eXchangeable Routing Language) is an instance-based workflow language that uses XML for the representation of process definitions and Petri nets for its semantics. Since XRL is instance-based, workflow definitions can be changed on-the-fly and sent across organizational boundaries. These features are vital for today's dynamic and networked economy. However, the features also enable subtle, bu... View full abstract»
