(七)不确定性分析项目评估具体作法的一个重要特点是进行不确定性分析。对项目进行评价分析,是在有许多假设条件的情况下进行的,许多投入产出的数值都是评估当时没有发生的。由于许多相关因素在今后有可能发生大的变化,由此产生投资效益的不确定性,给投资项目的建设带来一定的风险。为了预计今后的风险,也为了使项目今后能承受一定的风险,就需要作不确定性分析。不确定性分析是对决定项目经济效益的主要不确定性因素进行预测,然后分析这些因
(vii) Uncertainty analysis An important feature of project assessments is the analysis of uncertainty. The evaluation and analysis of the project are carried out under a number of assumptions. Many of the input and output values are not evaluated at the time. As many related factors may change significantly in the future, resulting in uncertainty of investment benefits, it will bring certain risks to the construction of investment projects. In order to anticipate future risks and also to enable the project to withstand certain risks in the future, uncertainty analysis is needed. Uncertainty analysis is to predict the main uncertainties that determine the economic benefits of the project, and then analyze these factors.
