Research On The Life Cycle Evaluation System Of Power Transmission And Transformation Projects Based On Decision Factors

The rapid development of China’s economy needs the support of electricity,so the demand for electricity in the whole society is increasing.Therefore,the power industry sector must continuously enhance its innovation capabilities and improve the operating efficiency and production efficiency within the industry.With the deepening of the reform of the investment system,the post-evaluation work of power transmission and transformation projects throughout the life cycle has received more and more attention from the state.The traditional post-evaluation of power transmission and transformation projects mainly focuses on the construction process of the project,and seldom considers the full life cycle of construction project,especially for the operation and maintenance phase,and decommissioning disposal phase.In-depth research on the post-evaluation system for the life cycle of power transmission and transformation projects will help to enhance the power companies’ ability to manage fixed asset investment projects,improve the company’s asset investment mechanism,and thereby enhance the company’s investment benefits.Therefore,the post-evaluation of power transmission and transformation projects plays an important role in the management and decision-making of investment projects.It is not only helpful for judging whether the objectives are achieved,and thus summing up the management capabilities of various departments.Moreover,through timely information feedback,it is convenient for enterprises to find shortcomings in the process of project decision-making and management as soon as possible,and reduce investment risks.Based on this,this paper introduces the life cycle theory to construct an evaluation system for power transmission and transformation engineering construction projects.First of all,based on previous research results,the project process management theory and project risk management theory,this paper analyzes the decision factors of the project in the process management and risk management dimensions,and constructs a set of decision-making factors for the life cycle post-evaluation of the transmission and transformation project.Secondly,the SNA method is used to screen the constructed set of decision-making factors,and a life cycle post-evaluation index system for power transmission and transformation projects based on decision-making factors is constructed.Thirdly,considering the characteristics of the life cycle post-evaluation of the power transmission and transformation projects,a fuzzy comprehensive life cycle evaluation model for the power transmission and transformation projects based on the combination of analytic hierarchy process and entropy weight method is proposed.Finally,practical examples are used to verify the validity of the proposed evaluation index system and evaluation model,then a life cycle post-evaluation system for the power transmission and transformation projects based on information feedback is designed accordingly,and the application process of the post-evaluation system is analyzed through examples.The main innovations of this paper are:(1)Based on the analysis of the decision-making factors for life cycle poer evaluation of power transmission and transformation project,this paper uses the social network analysis(SNA)method to mine the associated network,analyze the internal connections between the decision-making factors and identify the key indicators.In this way,the life cycle post-evaluation index system of transmission and transformation projects based on decision-making factors is constructed.(2)Considering the multi-level and fuzziness of the life cycle post-evaluation process of the transmission and transformation project,a fuzzy comprehensive life cycle post-evaluation model of the transmission and transformation project based on the combination of analytic hierarchy process and entropy weight method is established.(3)By analyzing the information feedback mechanism in the life cycle post-evaluation of power transmission and transformation projects,this paper constructs a post-evaluation system based on the information feedback mechanism for the life cycle of power transmission and transformation projects,which provides system support and practical reference for the post-evaluation of power grid projects.
