This paper considers a service-oriented architecture for enterprise integration and collaboration using semantic Web service technologies. A hierarchically-structured software system has been designed and developed in order to address the challenge of dynamic service composition. In comparison with existing service composers, the description of each Web service in our system is enhanced with domain-specific...
Effective collaboration is crucial to the success of collaborative virtual enterprise (CVE), an emerging business paradigm driven by the increasing trend of globalization. In this paper, we adopt a service-oriented architecture for enterprise integration and collaboration based on Web service standards. In order to tackle the technical challenge associated with the dynamic formation of business workflows,...
Collaborative simulation is proposed as a technique to support design evaluation with higher fidelity by addressing the interacting phenomena during the development of the complex product. To facilitate distributed simulation, high level architecture (HLA) was proposed and evolved as a standard with its specification, interfaces and data model. HLA provides simulation management for distributed component-...
Recent advancements in collaboration technology have shown that it is possible to convert existing single-user applications into real-time collaborative applications without modifying the source codes of the single-user applications. Such conversion relies on the API (Application Programming Interface) provided by the single-user applications. Poorly designed APIs make such conversion difficult, inefficient,...
Constraints allow users to declare relationships among objects and let the constraint systems maintain and satisfy these relationships. Formulas have been adopted to express constraints in a wide variety of single-user applications, because of their simplicity, efficiency and manageability. The needs and benefits of supporting formula-defined constraints in collaborative environments have long been...
The development of complex product is essentially concerned with multidisciplinary knowledge and requires computer supported cooperation among the designers. A multidisciplinary collaborative modeling and simulation (M&S) technology is an effective approach for the design and development of the complex product. The challenge now faced is how to apply the multidisciplinary M&S in the systematic...
Real-time collaborative editing systems may be applied in collaborative activities with a quite spontaneous and impromptu style. In such application activities, the session awareness information is particularly important. One key technical issue in achieving this flexibility is how collaboration sessions are managed in the system. However, existing approaches to session management are unable to provide...
In this paper, the architecture of collaborative modeling and simulation for the virtual prototyping of complex products is presented primarily. An approach of multidiscipline modeling towards HLA-based distributed collaborative design is studied. A HLA and Web services based framework and its key technologies of the distributed network environment to support multi-discipline modeling and collaborative...
Object grouping is an effective means for managing the complexity in graphics editing. However, research on collaborative object grouping has not been adequate. In this paper, we contribute a novel collaborative object grouping technique, called CoGroup. CoGroup can achieve maximal combined effects among compatible operations and preserve all users' work in the face of conflict without the overhead...
Telepointers are a real-time groupware interface feature to indicate where other users are pointing. None of existing telepointer techniques, however, is capable of tracking the reference object and preserving the relative position in the face of dynamic content and view changes in real-time collaborative document editing systems. In this paper, we report a novel object-associated telepointer (OAT)...
Effective interaction among participants is crucial to the success of a presentation. The workspace of a presentation, which is the presentation slides, is a natural and effective medium of interactions among presentation participants. However, due to the insufficient support from existing collaborative presentation systems, workspace-mediated interaction is inconvenient in presentations, especially...
Multi-way dataflow constraints are very useful in the development of collaborative applications, such as collaborative CAD and CASE systems, but satisfying multi-way dataflow constraints in the presence of concurrency in collaborative systems is difficult. In this article, we discuss the issues and techniques in maintaining multi-way dataflow constraints in concurrent environments. In particular,...
