摘　　要：电网企业是国民经济的支柱型企业,国家对电网企业的投资也越来越大,如何确定电网项目的投资策略是关系电网企业健康发展的重要因素.项目投资策略分析需要考虑的目标很多,以电网项目投资的综合收益最大化为目标,研究电网企业的项目投资组合.根据电网项目投资的经济性、可靠性以及电网发展性建立多目标函数,采用变权理论对多目标进行求解,从而得到电网项目的投资组合.该模型对电网企业科学的决策提供了一定依据,具有现实意义.The grid enterprise is the pillar enterprises of national economy. China is increasing the investment in grid enterprises. How to determine the investment strategy of power grid projects is an important factor to affect the healthy development of the power enterprises. A lot of goals should be considered to analysis the project investment strategy. The power grid enterprise pro- ject portfolio was researched with the grid investment consolidated income maximization consid- ered as the goal in this paper. A multi-objective function was established based on the economy, reliability, and grid development situation. Variable weight theory was used to solve the multi- objective, and the grid project portfolio was thus obtained. The analysis model provides some ba- sis scientific decision-makings for grid enterprises, which has a practical significance.
