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.

$\backslash$table$[[$Activity$,$IPA$*,\backslash$table$[[$Normal$],[$Duration$],[($days$)]],\backslash$table$[[$Crash$],[$Duration$],[($days$)]],\backslash$table$[[$Normal$],[$Cost $($$$)]],\backslash$table$[[$Crash Cost$],[($$$)]]],[$A$,-,7,5,500,640],[$B$,$A$,6,5,550,630],[$C$,$A$,8,5,800,935],[$D$,$B$,10,7,1,200,1,440],[$E$,$B$,$ C$,6,4,600,700],[$F$,$C$,4,3,500,590],[$G$,$D$,$ F$,4,2,700,1,000],[$H$,$E$,$ F$,7,4,650,950],[$I$,$G$,$ H$,2,2,300,300]]$

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
