基于灰色層次分析模型的電網(wǎng)建設(shè)項目風(fēng)險評價研究
[Abstract]:Electric power is the national basic industry, in the whole national development in the strategic core position. With the development of economy in our country, the demand for electric power is increasing gradually, and the demand for power grid construction project is increasing day by day in recent years. The process of power grid construction project is complex, the amount of funds is large, the main body is more involved, the construction period is long, and the risk in the construction process is becoming more and more complex. In recent years, there have been some cases of casualties caused by the failure of power grid construction projects, which makes people pay more attention to the risk of power grid construction projects. With the development of the new power reform, the risks to be considered in the power grid construction project will be more diverse, and the project will face more uncertainty in the process of implementation. It is of great significance to identify and predict effectively the risks of grid construction projects under the new situation and to evaluate and analyze them so as to formulate corresponding measures in a timely manner to reduce or avoid the risks of grid construction projects and to promote the smooth implementation of grid construction projects. Firstly, this paper expatiates the theory of power grid construction project risk from the relevant concepts, project implementation process, risk assessment, risk prevention and other dimensions. Secondly, the risk evaluation index system of power grid construction project is constructed from the risk identification theory, the principle of index selection, the design process and so on. Thirdly, on the basis of the analysis and evaluation method, applying the relevant theory of grey system, we improve the traditional tomography evaluation model, and construct the risk evaluation model of power grid construction project based on grey hierarchy analysis. Make the AHP evaluation model more reasonable; Finally, combined with the actual grid construction project, the application of the evaluation model for empirical analysis. Through the research of this paper, on the one hand, we can perfect the research on risk evaluation of grid construction project, on the other hand, we can identify and analyze the risk of power grid construction project under the new situation. It has certain reference significance for the grid construction project to guard against the risk and to do the coping strategy well in advance.
