This paper proposes a method for project selection based on stochastic dominance (SD) and fuzzy theory. Using fuzzy theory and stochastic dominance, the method is tested using data from real-world projects. The findings show the importance of the proposed methodology improved existing methods in two ways: (1) This research alleviates the subjective bias in risk assessment in estimating the expected value hidden in the project portfolio (2) Adding the stochastic dominance rule to the fuzzy ranking process contributes to efficiency in project portfolio selection. The study contributes to the literature by exploring the combination of both fuzzy theory and stochastic dominance. For practitioner significance, managers can identify key uncertainty factors and estimate value in managing project portfolios.

提出了一种基于随机优势（SD）和模糊理论的项目选择方法。使用模糊理论和随机支配力，使用来自实际项目的数据对方法进行了测试。研究结果表明，所提出的方法论在两个方面改进了现有方法的重要性：（1）这项研究减轻了风险评估中主观偏见，以估计隐藏在项目组合中的期望值（2）将随机优势规则添加到模糊等级中过程有助于提高项目组合选择的效率。该研究通过探索模糊理论和随机优势的结合为文学做出了贡献。对于从业人员而言，管理人员可以识别关键的不确定因素，并在管理项目组合时估算价值。
