In this class we give an overview of the "Engineering Economics" section of the course. We start by introducing the topic of the time-value of money.

Slides: We cover slides 1 to 24. Slides 19, 20 and 23 are exercises for you to do on your own.
Audio and video recording of the class
Self-learning: here's an interesting PDF explaining time value of money and engineering economic concepts
Enrichment: I mentioned an article about packed distillation towers in class today.

We continue considering the time value of money (TVM) and do some class exercises.

Slides: We cover slides 24 to 29. Slides 30 and 31 will feature in the next tutorial.

We wrap up the TVM section with one more example and then continue looking at Measures of Profitability: slides 32 to 42
Audio and video (bad sound!)

We will wrap up Measures of Profitability (slides 49 to 54); including jumping ahead to slides 88 to 90.
If you are looking for some more information regarding NPV vs DCFRR, please read this tutorial, or use this Google search to understand the subtleties.

We will (re)cover the effect of depreciation and taxes on NPV, slides 78 to 83 and go through the tutorial/assignment 3. We will also discuss the SDL project selection procedure.
Please see this PDF slide 80 from the course notes. Note the following relationships
- \( \text{G} = \text{C}+\text{E} \)
- \(\text{H} = (\text{A} - \text{B}) - \text{G}\)
- \text{H} = (\text{A}-\text{B}) - \text{G}
- J = \(\text{H} \cdot p_\text{tax}\)
- L = NCFAT = (A - B) - J = A - (B+J) = Net profit - tax = Total income - (After tax cash flow out): this is the line we use for our NPV calculation
- M = \( \displaystyle \frac{\text{L}}{\left(1+i_\text{MARR}\right)^n}\)
