Roger Ginde is developing a program in supply chain management certification

for managers. Ginde has listed a number of activities that must be completed

before a training program of this nature could be conducted. The activities,

immediate predecessors, and times appear in the accompanying table:

$\backslash$table$[[$ACTIVITY$,$IMMEDIATE PREDECESSOR$($S$),$TIME $($DAYS$)],[$A$,-,2],[$B$,-,5],[$C$,$B$,1],[$E$,$A$,$ D$,3],[$G$,$E$,$ F$,10]]$

a$.$ What is the project length?

b$.$ What are the critical activities?

c$.$ How much slack is in activity C$.?$

d$.$ What is the early start$/$early finish and the late start$/$late finish for activity F$.?$

e$.$ What if activity F was delayed by $12$ days. What impact would it have on the project and critical path?

$\backslash$table$[[$Activity$,$Norm Time,Crash Time,Crash $$,$Normal $$,$Predecessors$],[$A$,3,2,45000,30000,],[$B$,8,5,210000,150000,$A$],[$C$,3,2,50000,40000,$B$],[$D$,5,3,70000,60000,$A$],[$E$,4,2,30000,25000,$B$],[$F$,2,1,27,000,18,000,],[$G$,3,2,28000,20000,$D$,$ E$],[$H$,3,2,21000,15000,$F$],[,2,2,20000,20000,$G$]]$

a$.$ What is the project length?

b$.$ What activities are on the critical path?

c$.$ What activity should be crashed first and what is the cost?

d$.$ What is the maximum that can be crashed from the project and what is the total cost?
