传统的风险评价方法中,主观因素影响较大,因此为了减少或避免主观因素以及模糊随机因素的影响,本文将灰色预测理论运用到供热机组扩建工程项目的风险评价问题上,通过建立客观合理的供热机组扩建项目风险评价指标体系,将定性分析和定量分析相结合,构建多层次灰色综合评价模型,并通过实证分析研究了案例中供热机组扩建工程的风险性评价。灰色理论的应用,增加了对该项目风险评价的科学性、解释性和可信度。本文提出用多层次灰色预测法对供热机组的扩建工程进行风险性评价的方法。
Therefore, in order to reduce or avoid the influence of subjective factors and fuzzy random factors, this paper applies the gray forecasting theory to the risk assessment of the expansion project of a heat supply unit. By establishing an objective and reasonable The risk assessment index system of the expansion project of heating units was established. By combining the qualitative analysis and quantitative analysis, a multi-level gray comprehensive evaluation model was constructed and the risk evaluation of the expansion project of heating units in the case was studied through empirical analysis. The application of gray theory adds scientific, explanatory and credibility to the project’s risk assessment. In this paper, a multi-level gray forecasting method is proposed to evaluate the risk of expansion project of heating unit.
