When there are two or more options, then one must use net current value method, net year-end value method, cost current value and cost year-end value method to make a judgment and find the most optimal option 如果是两个以上的方案需要用净现值法、净年值法、费用现值法和费用年值法进行判断,从中选出最优方案。
For deterministic project using single project analysis, one can use net current value method, internal benefit rate method and investment return rate method, and then use the results to determine the feasibility of the project 如果是确定性投资项目并且是单个项目做分析,可以用净现值法、内部收益率法、投资回收期等指标。根据指标的结果判断项目在经济上是否可行。
