Construction Project Example

Consider the construction project defined by the precedence table and the AON network diagram below.

$\backslash$table$[[$Activity$,$Predecessor,Duration $($days$)],[$A$,--,8],[$B$,--,10],[$C$,$A$,3],[$D$,$A$,$ B$,7],[$E$,$A$,$ B$,6],[$F$,$C$,7],[$G$,$D$,$ F$,5],[$H$,$E$,$ G$,3]]$

$1$ point

The critical $($i$.$e$.,$ the longest$)$ path is

Start $$ A $$ C $$ F $$ G $>H$ End

Start $B->$ D $$ G $H->$ End

Start $->$ B $->$ E $-->$ H $-->$ End

Start $A-->H$ H $$ End

$3$

$1$ point

How long will it take to complete this project $($in cirys$)?$
