Abstract:
Railway emergency management has
gradually shifted from reaction planning to scenario planning
when an emergency occurs. As such, an effective
approach to integrated information management based
on the "scenario-response" mode has become of considerable
value in establishing a scenario model for railway
emergency. First, the scenario elements of railway
emergencies were classified by scenario analysis
to set up a hierarchical network model for railway emergencies.
After the analysis of the requirements, sources,
and characteristics of information for scenario building,
an approach to integrated information service for
railway emergency scenarios based on the Service-
Oriented Adaptive Agent Collaborative Model was proposed.
Such approach could meet the requirements for
autonomy and flexibility of an integrated information service
under railway emergency conditions. Agent technology
was adopted, and the Web service proxy was
provided by the software agents in the proposed approach.
The global scenario model was divided into
many local procedure models in different departments,
which distributed the control of integrated information
service to numerous service nodes. Experimental results
showed that the integrated information service
system based on the proposed approach is significantly
more autonomous and flexible than the integrated model
based on the Business Process Execution Language
for Web Services.
