$14-4.$ For the project outlined in the following table, prepare $($a$)$ a bar chart, $($b$)$ an AOA network

diagram, and $($c$)$ AON network diagram. $($d$)$ What and how long is the critical path?

$14-5.$ For the project in Problem $14-4,($a$)$ provide a worker$-$level profile, assuming that all tasks begin

as early as possible; $($b$)$ repeat the profile, assuming that no more than nine people are available in

any week and the manning level for a task cannot change; and $($c$)$ identify the project duration in

each case.
