Distributed Cooperative Mechanism and Application for Monitoring of Urban Subway Construction

In this paper, combining the technologies of Computer Supported Cooperative Work (CSCW), Workflow and Network, the authors aim to organize virtual distributed cooperative work environment (VDCWE) and expound the running mechanism of cooperative workflow and design its algorithm for monitoring of urban subway construction. And then a prototype system was built based on the above, capable of supporting user analyzing, dealing with and managing data of monitoring, and real-timely releasing corresponding information, providing interactive virtual and distributed coordination meet-environment, dynami-cally and transparently, in favor of clients’ interoperability and solving practicing problems, and so on.
