试题解析
  在可行性研究或项目评估的经济分析中,都是以确定的数据为计算前提。事实上项目建设过程中存在着许多随时间、地点、条件改变而变化的不确定因素(如物价变动、投资变化、工艺技术变化、生产能力变化、新产品和新材料的应用、政策变化等)。这些不确定因素构成经济分析中的不确定性。为此,还必须研究分析各种具体不确定因素对建设项目经济效益的影响。计算出产晶价格、生产规模、成本、贴现率、投资、投产期等因素变化时项目盈利的变化,估算出对经济考核指标有重大影响的敏感因素及其变化范围、在此范围内的概率,从而为项目的决策提供更为可靠的依据。这种以不确定因素对建设项目经济效益影响为内容的计算和分析称为建设项目不确定性分析。 不确定性分析的方法很多,用得较为普遍的有盈亏平衡分析、敏感性分析和概率分析三种。
