QUESTION $1$:

Ponds Engineering Company won a new project. They have to perform several activities. Following table and network provides information about the project:

Normal Crash Normal Crash

Activity Time $($days$)$ Time $($days$)$ Cost $($$$)$ Cost$($$$)$

A $755020068900$

B $882790027900$

C $875630063080$

D $985630066460$

U $1295010081270$

V $764510054945$

W $873971054425$

FOLLOWING NETWORK IS DRAWN WITH NORMAL TIME $($DAYS$)$: $[$DO NOT Include this network in the solution$]$

$($a$)$ How many paths are there in the network?

$($b$)$ How many paths in the network started with the activity $$G$?$

$($c$)$ What is the normal project completion cost?

$($d$)$ What is the project completion time?

$($e$)$ State critical path$/$s in the network?

$($f$)$ Assume that the project manager wants to shorten the project by five DAYS. What crashing decisions do you recommend meeting the desired completion time? When tie, must prefer least cost.

To answer part #$($e$)$ MUST fill out the given table and MUST support your work separately.
