摘要
针对项目经济评价中存在的不确定性,提出了基于区间分析的项目经济评价方法。区间分析是以"区间数"为处理对象的一种不确定性数学分析方法。当各要素(如现金流、贴现率等)为区间数时,研究了求解区间净现值和区间内部收益率的方法,给出了通过区间净现值和区间内部收益率进行项目经济评价的规则,并研究了这2种方法。结果表明,在进行项目经济评价时,2种方法本质是一致的。
This paper presents a method of evaluation of project economy based on interval analysis to improve the certainty of the evaluation. Interval analysis is an uncertainty mathematical method dealing with interval numbers. When uncertain elements, such as cash flow and discount rate, can be expressed with interval numbers, another method is proposed for finding interval net present value （NPV） and interval internal rate-of-return （IRR）. The paper gives rules of evaluation of project economy via interval NPV and interval IRR. The relation between the two methods is studied, and it is concluded that the two methods are essentially accordant.
