考虑关联性的电网建设项目经济效益后评价研究

Post-Evaluation of Economic Benefits of Power Grid Projects with Consideration of Relevance

电改环境下电网公司需要以更加市场化的眼光评价已建成电网建设项目的经济效益,以为同类建设项目提供管理决策支持。提出电网项目经济效益后评价模型,从相互关联的建设成本、财务效益、社会经济效益和环境影响成本4个方面构建网络层次结构指标体系,运用ANP方法求解相互关联的指标权重,引入犹豫语言评语方法为决策者服务,通过云模型集结各指标评价结果,并利用辽宁省已建成的电网建设项目为案例,验证了模型的合理性和可行性。

In the context of electric power system reform, power supply companies have to estimate the economic performance of the constructed power grid projects with a more market-oriented perspective so as to provide a support for management decision-making of similar construction projects. An economic benefits post-evaluation model is proposed for power grid projects and an index system with network hierarchy is built which consists of such four relevant factors as construction costs, financial benefit, social benefit, economic benefit and environmental impact costs. The ANP method is applied to solve the weight of relevant index, and the hesitant language evaluation method is introduced to serve the policymakers. Finally, the cloud model is used to assemble every index evaluation result. Three power grid construction projects built in Liaoning province are used to verify the feasibility and rationality of the proposed model.
