challenge and competition are become more and
more serious, which makes it very obvious that
construction needs information. In recent years, IT
technology has widely developed, which in
Financial Management, Office automation, Real-
time monitoring site, Remote communication, in
construction field. Part of the management
department has established computer management
information system which covering the management
functions, such as Material Management System,
Project Budget Software, Progress Management
Software, which can inspire the Industry
management.
But the informatization of the whole industry
have suffered a lot of frustration, which can be
described as a failure rather than an evaluate, in
recent years. By the practice from the author in the
information technology industry, the following
factors cannot be ignored.
2.1 Confined to Department Classes
and Difficult to Expand
Because information tools that most of construction
industry has used are in the level of department
classes and standards are not uniform, it make
interchanges and interconnections very hard. While
most of companies of construction industry are ran
in the collectivize operation, they need some
projects in the side of collectivize control to raise
companies’ comprehensive management levels.
High-speed railway system consists of High-speed
railway operation, High-speed railway facilities and
High-speed railway management policy. As a
subsystem of the transportation system, it’s most
important function is to satisfy Users’ travel demand.
Therefore, this paper used the concept that high-
speed railway is service in "person" as a starting
point, and the influencing factors of User s’ travel
choice as the breakthrough point, to research high-
speed railway and the influencing factors of uses’
travel choice. Through data analysis and
investigation, this paper determined high-speed
railway users’ travel choice index system, including
five influencing factors of high-speed railway users’
travel choice and one factors for evaluation of the
result.
If this problem was not solved, at certain stage, it
would make the management software cannot meet
the demands of upper management and gradually
cannot use. For an instance, it is unable to complete
the task of issuing control indexes and providing
related superior comprehensive reports.
2.2 Disability to Support the
Multi-organisation and
Multi-format
In fact, construction industry many braches, most
construction enterprise are not satisfied with the
traditional flat industrial structure. For example,
most enterprise are developing in diversity which in
the low level and repeat competition in simple civil
engineering, and a large construction group always
has subsidiaries including housing construction
company, installation company, road and bridge
corporation and so on. Of course, all of these
subsidiaries are different in management for
business difference. But now, the product which has
applied in much enterprise can't satisfy the
requirement which can apply in multi format in
multi-organizational group. As times go, this
situation will constrain the enterprise's management
and accessing to information. What’s more, it will
lead to that data can't be generated by system.
This section must be in one column.
2.3 Disability in Application of
Multi-mode
It has many management-modes For a construction
enterprise in a period .Such as, governance structure
in project-management will have a numerous modes
including Legal management project, contractor
management projector-operating items. This
situation will last a long time for the Chinese
national conditions. How to make our software
system to meet the requirements totally is not
unclearly.
All above make enterprise informatization get
away from the management practice in the process
of informatization .As a result; It caused the failure
of the establishment of the informatization.
Four-stage method is based on investigation and
familiar with the situation of traffic, finally predict
the future distribution. The basic steps are traffic
generation 、 traffic distribution 、 traffic model
selected 、 traffic assignment. We can gain some
parameters about cargo flow through investigation.
But it is difficult to implement, it will cost a lot of
manpower, material and financial resources, so the
minimum cost maximum flow is better to optimize
the road network. The so-called minimum cost
maximum flow problem is finding a maximum flow
f, simultaneously the total cost is minimum.
Studying this problem is trying to find out: from A
to B, how to choose the path, how to assign traffic
flow, in order to achieve minimum cost. The
ONLY FLEXIBILITY CAN ADAPT TO THE OUTSIDE WORLD, AND ONLY SOLIDIFICATION CAN UNIFY THE
WHOLE SYSTEM
