摘　　要：电网企业项目投资资金规模大、项目多,如何根据固定的资金确定电网项目的投资组合是关系企业健康发展的关键因素.不同企业的运营状况有所区别,选择项目时侧重点也不一样.根据电网项目投资的经济性、可靠性以及发展性建立投资组合模型的多目标函数,根据不同企业的运营情况,采用变权理论均衡各个指标的常权权重,进而将多目标函数转化为一个目标的函数,求出电网企业的最优项目投资组合.该模型对于企业根据自身情况确定项目投资策略具有科学指导意义.Due to the large investment funds scale, many projects are existed in power grid enterprises. How to determine the grid project portfolio is a key factor in the healthy development of the enterprise based on the fixed capital. However, for different enterprises, its operating performance is different, so the focus of choosing the project is not the same. This paper is based on the economy, reliability and the development of grid investment to create a multi-objective function of portfolio model. Then based on the different enterprises operations, variable weight theory is adopted to determine the weight of each index, and changes multi-objective function into a target function. Finally, Optimal project portfolio of power grid enterprises is obtained. The model has scientific significance for enterprises to determine their investment strategy according to themselves situations.
