Abstract
The city gas transmission and distribution system is an important energy supply
facility for ensuring the residential and social production. Therefore, it is significant that
the city gas transmission and distribution system can construct in order and run stably.
The station for city gas transmission and distribution is an important part in the city gas
transmission and distribution system. And, it plays an important role in the process of
city gas transmission and distribution. Therefore, the project post-evaluation work can
contrast and analysis the difference and reason between the actual effect of project and
the predicting of project in the preparation stage. It can summarize the experience and
exhortation and put forward the solution countermeasure. In the paper, it constructs the
project post-evaluation system of station for city gas transmission and distribution in the
theory of city gas transmission and distribution, project post-evaluation, project
reliability and project evaluation. Then, it carries out a practical application.
Firstly, the paper expounds the theory of city gas transmission and distribution,
project post-evaluation, project reliability and project evaluation systematically. And, it
provides the necessary scientific theoretical foundation for the further research in the
project post-evaluation system of station for city gas transmission and distribution.
Secondly, the paper selects the project post-evaluation indexes and constructs the project
post-evaluation index system for the city gas transmission and distribution station in the
base of setting principles for the project post-evaluation index. In addition, it constructs
the project reliability identification model. Then, it calculates the reliability of the project
post-evaluation index system for the city gas transmission and distribution station, and it
makes a reliability identification. Thirdly, because the project post-evaluation system of
station for the city gas transmission and distribution is a system that includes a variety of
factors and needs a measure to the qualitative description of evaluation index, the paper
selects the G1 weight determination method as the theoretical basis for the evaluation
index weight determination and selects the matter-element analysis method as the
theoretical basis for the project post-evaluation. Then, it establishes a mathematical
model for the project post-evaluation of station for city gas transmission and distribution.
Finally, the paper selects four stations for the city gas transmission and distribution that
are constructed and ran in BJ City as cases and makes an application for a mathematical华北电力大学硕士学位论文

model for the project post-evaluation of station for city gas transmission and distribution.
Then, it gets the project post-evaluation conclusion. Practice illustrates it has the feasible
operability that the project post-evaluation system of station for the city gas transmission
and distribution constructed in the paper.
It can provide a disciplined, scientific and systematic approach for the project
post-evaluation work by the construction of project post-evaluation system of station for
the city gas transmission and distribution. It is beneficial to improve the decision-making
and investment benefits, and to strengthen the regulatory in the implementation, and to
enhance the responsibility sense of the participating units and personnel. All in all, it can
play a positive role in enhancing the construction and operation level of the city gas
transmission and distribution facilities.
