Abstract
Case-based reasoning (CBR) is a method that uses previous experiences to solve
new problems. The characteristics of CBR make it suitable for complex
problems related to knowledge reuse. Based on the analysis of the characteristics
of emergency events in urban rail transit, a generation method using CBR for
emergency scheme is proposed. Certain related technologies, such as case
representation, case retrieval, case adaption, case revising and case retaining, are
conceived and discussed. A numerical example is used to illustrate the
application and efficiency of the proposed method, which can take full advantage
of historical correct experiences and benefit to the intelligentization of
emergency scheme generation for urban rail transit.
Keywords: urban rail transit, emergency scheme, case-based reasoning, case
retrieval.
1 Introduction
Accidents, failures, unpredictable disasters, and sudden increase of passenger
flow due to special events happen in urban rail transit (URT) now and then.
These emergency events, which impact widely and long and evolve uncertainly,
will bring negative impact on the whole rail network unless properly dealt with.
In terms of URT, on one hand, operation organization and passenger evacuation
are constrained by the spatial layout because of the relatively closed space in
URT system. On the other hand, emergency response process for URT actually
is a process of interaction and cooperation between different departments, which
is difficult to do well due to the distinct differences existing in the
communication, coordination and authorization. Therefore, it is visible that the
emergency decision in URT is complex and difficult.
