1 GENERAL
This article firstly define the smart living space and
it’s six application aspect which is widely used under
the Internet of Things, subdivide and analysis the
researches home and abroad when study the relative
issues about smart living space assess theory system
of the “Internet of Things” technology
Smart living space (Smart Space) is a working
space embedded with calculation and information
equipment, in order to letting users search
information and get computer service conveniently,
working more efficient isolated or collaborated
(NIST).
We define Internet of Things (The Internet of
Things) as "material objects which connected to the
Internet", using radio frequency identification
(RFID) devices, infrared sensors, global positioning
systems, laser scanners and other information
sensing equipment, as agreed in the agreement, make
everything connected to the Internet, and try to
exchange and transfer information, and to achieve
intelligent identify, locate, track, monitor and
manage a network (Lin, 2010).

referred to as ETC) and other aspects of the great
role.
The six aspects are selected for detailed study
based on the following considerations:
1. The six directions are a crucial aspect of
national economic development, related to the
process of building a socialist harmonious society, it
is a break point of achieving low-carbon-saving
targets, promote independent innovation saving and
low carbon goal to, improve service level of an
important breakthrough, to deepen reform, A
necessary requirement to improve the level of
openness.
2. The six directions are closely linked as a
whole, smart building research is bound to lead
smart home smart grid and smart campus research,
smart home and smart grid with the development of
intelligent building has become an inevitable
direction. The development of smart highways will
inevitably bring the upgrading of China's logistics
industry which will surely continue to promote the
modernization of logistics technology and thus
promote the logistics storage level
3.The six directions respect the development of
China's national conditions and we must develop
them rapidly.From foreign research point of view,
this six researchs have become the consensus of all
countries, and from April 2010 the State Council
issued the "National ten" can be seen that they are
not only an academic problem, but is related to
Long-term stability of our country's important
political issue.
2 DEFINITION AND
SIGNIFICANCE
2.1 Definition of Related Concepts
Intelligent quality is used to evaluate the level of
achievement of intelligent control system according
to certain algorithms evaluation index system and
evaluation, quantitative assessment. Intelligent
Building is equipped information and
communication, office automation and information
services building automation of various functions,
easy to govern activities which the buildings need
Smart Home is to use advanced computer
technology, network communication technology,
integrated wiring technology, according to
ergonomic principles, integration of individual
needs, associated with the various subsystems home
life together, in order to achieve user-centric
experience at home (Pinghua, 2010).
Smart Grid refers to the immediate connection
interactive between customers to, customers and to
power companies, Achieving to read data timely,
efficiently in a dually way, that will lead to
promoting the comprehensive efficiency of the
integrated power grid (Guangyu and Yingyun,
2010).
Smart campus is using the school as a platform,
using the integrated wiring technology, network
communication technology, intelligent campus -
security system design technology, automatic control
technology, audio and video technology which will
be integrated campus-related facilities, in order to
build efficient infrastructure and the schedule of
campus affairs Management system to improve
campus safety, convenience, comfort, artistry, and to
build an environmental-friendly campus. [5].
Smart storage combine the real-time computer
software with the advanced information technology,
sensor technology, operational research, artificial
intelligence and system technology to apply in
storage management, in order to optimize the
information, resources, behavior, inventory and
distribution behaviors according to the regulations
and rules of logistical act, maximizing the effective
throughput and precision to meet the management
requirements of the intelligent system [6].
Smart highways refers to the advanced infor-
mation technology, data communication technology,
control technology, sensor technology, operations re-
search, artificial intelligence and system integration
to effectively integrate technology used in highway
construction and management, it has a language,
math, logical reasoning , Visual simulation or re-
placement body parts movement, thereby strength-
ening vehicle, road, the links between users, the for-
mation of a safe and efficient transport system [7].
2.2 Research Significance
2.2.1 Smart Building

and regard improving warehouse Efficiency of the
logistics industry as the first consideration [10].
Through our own research with the specific
expectations of the actual situation, we want to
feasible with Chinese characteristics as soon as
possible, the assessment system, which will
effectively promote the cause of intelligent
warehouse full and healthy development,
2.2.6 Smart Highways
As the research in intelligent highway just beginning
in China, this advanced technology in learning from
international experiences, combined with the actual
situation of the specific form a workable evaluation
system, and promote the cause of the continued
development of intelligent highway

Currently, there are many methods to the determina-
tion of the weight, such as: the subjective weighting
method, the expert scoring method, Delphi method,
AHP, etc., there are large differences between the
four methods.

2. Structure Matrix
After Level hierarchical structure established, the
relationship of affiliation will be followed to
establish between the upper and lower index, we can
make fuzzy judgments by using AHP pairwise
comparison method of the relative importance of
each indicator , Finally quantify data in accordance
with the scale of Satty , As shown in Table 3-2:

RI is a random consistency index, its value
determined by Table 3-3.

RI.
When n<3, the determine matrix always has
complete consistency. Usually, when CR <0.1, we
determine the matrix is satisfied the full consistency.
Otherwise, we need to adjust the matrix, which
satisfies the conditions CR <0.1, making it consistent
with the complete satisfaction.

2. Plan the Grade Standards of Evaluation
Indicators
by planing Index score standards of the level, we
turn the qualitative indicators into quantitative
indicators, with the use of expert score, which
will be assessed three indicators
as "excellent
", "good", "medium "and"poor " , And give a
certain score, score on behalf of indicators
