Question $1$:

Consider the following project:

$\backslash$table$[[,,$Duration $($days$),$Total cost $($$$)],[$Activity$,$IPA,Normal,Crash,Normal,Crash$],[$A$,---,10,8,100,120],[$B$,--,6,4,80,90],[$C$,--,3,1,95,125],[$D$,$A$,12,9,140,200],[$E$,$B$,6,3,65,115],[$F$,$B$,$C$,8,8,75,75],[$G$,$E$,$F$,18,13,228,318]]$

a$.$ Based on the normal time, draw the activity on an arrow network for this network.

b$.$ Identify the critical path and the expected completion time.

c$.$ Based on the normal time, draw the Gantt chart and show the critical path on the chart.

d$.$ Determine the crashed duration for this project and the cost associated with it$.$

e$.$ Based on the crashed time, draw the activity on an arrow network for this project.

f$.$ Using MS project, perform part c
