摘　　要：电网企业项目投资资金规模大、项目数量多,如何根据固定的资金,结合企业的运营状况去确定电网项目的投资组合是关系企业健康发展的关键问题。首先基于电网项目投资的经济性、可靠性以及发展性建立一个多目标函数的投资组合模型,然后根据不同企业的运营情况,采用变权理论确定各个指标的权重,将多目标函数转化为一个目标的函数,最终求出电网企业的最优项目投资组合。As the project investment in power grid has the characteristics of large scale and great number, it is a key issue for an power grid enterprise to make a good portfolio of projects according to its investment funds and actual operating performance so to ensure the enterprise being in healthy development. Based on the economy, reliability and expansibility of project investment, this paper sets firstly up an investment model with a multi-objective function. Then the multi-objective function is changed into a single-objective function by using variable weight theory to determine the weight of each index. Finally, the optimal portfolio of projects is obtained for the enterprise.
