With the increase of power grid investment and construction tasks,the extensive investment in the past cannot meet gradually precise management at present;power grid project cost management is more and more important.The cost control evaluation criteria and scoring rules implemented in Tianjin Electric Power Company now are too simplistic to fully reflect the cost control management level.Therefore,the construction of a scientific,feasible and effective comprehensive evaluation model will play an important role in improving the overall cost control level of the power grid project and help reducing management shortcomings.This thesis first studies the current situation of engineering cost control and the influencing factors at home and abroad,combines the actual situation of Tianjin Electric Power Company,then summarizes the influencing factors of power grid project cost control through literature reading method.After this,the importance of each factor is scored by questionnaire survey,and the key factors are extracted by factor analysis.Through this,an evaluation system including 4 first level indexes and 20 second level indexes are established.Due to the complexity and uncertainty of the index above(for both quantitative indexes and qualitative indexes are included),this paper uses AHP-entropy method to calculate the index weight at all levels,and finally establishes the two level fuzzy comprehensive evaluation model by using FCE method.Through construction of the evaluation index system and the evaluation model,we can find many problems waiting to be solved.Finally,an example is used to verify the effectiveness of the practicability of the evaluation results,and provides a reference for the continuous improvement of Tianjin electric power company. |
