Question $1$

Calculate the normal, least$-$cost$,$ and crash durations for the following project. Calculate the cost

associated with each duration. Indirect $($overhead$)$ costs are $$100$ per day.

Immediately preceding activity.

Tip: To use the network diagram given below and perform time$-$cost trade off calculations.

Rubric:

$$ Time$-$cost trade$-$off calculation table $($Correct calculations, professionally done$)=80$ points

Time$-$cost trade$-$off calculation table $($Correct calculations, roughly done, free hand$)=50$

points

Summarizing Result $($correct$)=20$ points
