MARR: Minimal Accepted Rate of Return

discounted:已貼現的

Economic feasibility analysis:

1. Payback Analysis: 投資回收分析

  [1] Create a time line

  [2] 應用cash flow到每一個period

  [3] 計算Payback

這種方法雖然簡單,但現金流不是貼現的。可以使用Discounted Payback方法來避免這個問題。

  Payback Period = (Initial Investment / Net Annual Cash Flow)

  投資回收期 = (期初投資/年淨現金流量)

  例: Initial Investment=90,000.00

        Cash Flow: yr1=10,000.00  yr2=20,000.00  yr3=20,000.00  yr4=50,000.00  yr5=30,000.00

        Payback Period = Number of years before full recover + Un-recovered cost at the start of the year four / (Cash flow during the fourth year / 12)

                                  = 3 + 40000 / (50000 / 12) = 3 years 10 months

2. Net Present Value(NPV):淨現值

  [1] 找出每一筆現金流的Present Value(PV現值)。貼現現金流。

  [2] 貼現現金流和期初投資的和就是NPV。

  [3] 如果NPV大于或是等于0,可以考慮做此項目。

  [4] 如果比較多個項目,則NPV較大的項目較可取。

3. Return On Investment(ROI):投資回報率

    ROI = PV(B - O&M) / PV(O&M + Initial Investment)

    ROI = (B - O&M) / Initial Investment

      O&M: Operation and Maintenance(? 不知是不是這個意思)

      B:Benefit效益(?不知道是不是這個意思)

4. Incremental Benefit/Cost Analysis 增量效益/成本分析

5. Cost Effectiveness Analysis成本效益分析

    方法: Numerical and Non-Numerical Scoring Models(數值及非數值評分模型)

6. IRR Internal Rate of Return: 内部收益率

    (PV) Cash Inflows - (PV) Cash Outflows = 0

    NPV = 0
