Abstract: This article on plans to improve the design of library-type research, based on the existing research of

"scenario" theory, focusing on finding how "Scene" elements change with the sudden through the

corresponding mathematical model, and forming the corresponding model (that is the "scenario" network).

Through sorting the analyzing the events that have occurred, extract "Scene" elements, Enrich library plans,

so that enhance security management system for real emergency warning capacity.

1 INTRODUCTION

1.1 Realistic Background

In recent years, with rapid developing of the era,

unexpected events frequent happened home and

abroad. How to better respond to emergencies and to

manage emergencies has become a major issue.

When provides for the convenience of living, there

are a variety of their potential for unexpected

security problem, such as earthquakes, floods, fires,

stampede, locomotive equipment failure, terrorist

attacks, traffic accident, car accidents etc. possible

incidents. Emergency management system can be

seen as a very complex system, contains the current

rail transit subsystems of the business, Such as

SCADA, BAS, FAS, ATC and AFC system etc. (Liu

Guangwu, 2009) So, this will use the Beijing urban

rail transit vehicle safety emergency management as

a platform, giving improve design to emergency

management of the present security emergency plans

for intelligent subsystem model library, based on the

rising 'scenario - response' model.

Currently, Beijing urban rail transit system has

built a comprehensive platform for rail

transportation of emergency relief, but mainly based

on "Forecast - response" model. For unexpected

events, especially non-routine incidents without aura

and are complex, always harm seriously. (Li

Shiming, 2009) However, using 'scenario - response'

model can make it more flexible to deal with

emergency.

1.2 Theoretical Background

For the 'scenario' concept, is still in the stage of

extensive debate having no specific conclusion,

different researchers have different interpretations.

In this regard they have relatively leading research,

and applied to many important areas in foreign.

Candolin design a context aware framework, which

can be performed in the mobile military networks

for the pre-task, and get access to a particular

situation, provides a solution for the war

communication system of the future. (Candolin C,

Kari, HH 2003); Grossmann establish an

infrastructure for large-scale scenes, classifying and

characterizing the data of scenes, as well supporting

multiple types of scenarios aware applications, then

improve the ability to reuse and share data.

(Grossmann M, 2008)

At the same time, some scholars in China also

went to study in this area. 'Scenario - response' is

corresponding measure forming and developing

based on the past events and understanding of the

law and convergence. Another statement is it is the

process of building a vision by using of scattered

blocks and puzzles (the elements of preparedness of

the emergency).(Liu Tiemin, 2009) Whereas

Automation Departments of Chinese Academy of

Sciences said that 'Scenario - response' is a process

of conscious change which are Scenario elements to

solving Predictable and unpredictable, Known and

unknown, Simulation and Can not be simulated

situations, for it analysis is more important than the

process. Meanwhile, Scenario should also be a

collection containing many important parameters.

1.3 Literature Review

Now, in China research for this problem is still

relatively empty stage, however, study abroad is

relatively mature. Research institutions in developed

countries, Such as the U.S. NSF, UK e-Science etc.

had many years of research in emergency response

mechanism and also established emergency

management system which are more influential, as

U.S. 'national emergency response system',

European EUREKA program in the "major

emergency intelligent management system" (MEM

brain), Japanese 'Disaster Response System' (DRS)

etc.

Professor Huang Jun of Graduate School of

Chinese Academy of Sciences state from demand

aspect that we need the 'Scenario' method to deal

with emergency management of unexpected events

that we can not predict the circumstances. Some

studies have sucked context concept into the

traditional public emergencies to integrated the

context and management of public emergencies,

hoping that through the process of plan formulation

and context of the calling plan to improve operation

efficiency of the emergency management system

(Xu Youzhi, 2009) Some studies also will construct

a static relationship between objects based on the

workflow process of the static model and for the

emergency control of the dynamic model of

workflow and build support for dynamic

collaboration across the emergency management

system. (Xu Ruihua, 2008)

2 OUTLINE

a) Form the 'scene points' to the corresponding

'scene networks' by Neural network model,

then find the appropriate solution to the

problem from the model database and

decision support system.

b) Analysis the effect of the emergency plan

database to security management system.

c) Analysis the application of "Scenarios"

model in the library design.

d) Concluded that 'scenario - response ' model

can improve the practical application of the

security emergency management system.

3 METHODS AND APPROACHES

3.1 Overview

In terms of model building, including rough sets and

neural network processing section.

a) Rough set processing stage: According to

rough set of simplified rules and decision

rules on the 'scenario' data reduction,

structure the initial structure of neural

network to facilitate the training of neural

networks.

b) Good neural network parallel processing,

approximation, classification capabilities to

deal with such nonlinear problems risk

warning, Processing stage through the

rough set dealt with the "scenario" data into

early warning network, The related

'scenario' data on the impact of events as

the 'neurons' and the weight of the

combination model (Wang Bo, 2010)

3.2 Model

a) Extracted the 'scene' elements from the

incident, as entry in the hidden layer neural

network to combine mapping after putting

out emergency plans. (Wang Chengliang,

2010)

output layer are designed totally on demand,
