Please help me with my homeork. I know it is two separate pictures, but it is all part of one question. Please zoom in to see questions better. They are not blurry!! I will rate! Thank you in advance!
b) The critical path for the network showH IS! DU 3. Given the following information, develop the optimal time-cost solution. Note that indirect project costs are maximum of $1,000 per day. Activity Nermal Time Crash Time Cost per Day to Crash od S500 300 700 600 a) Determine which activities are on the critical path, CP length, and the length of the other possible paths. Critical Path Non-Critical Path Activities: b) Rank the CP activities in ascending order (the lowest crashing cost first), and determine the number of days each can be crashed Activity Cost per day to crash Available daysExplanation / Answer
a) Critical Path- C-D-E-F----Path length=20 days
Non Critical Path-A-B-F-----Path Length=18 days
b) Activity Cost Per day to crash Available Days
C $300 1
E $600 2
D $700 3
F $800 1
c) Step 1- Shorten activity C by 1 day
Shorten activity E by 2 days
Shorten activity F by 1 day
Shorten activity B by 2 days
Now C-D-E-F duration =20-4=16 days
Now A-B-F duration=18-1=17 days, After shortening B by 2 days, A-B-F duration=17-2=15 days.
d) Path Activity Crash cost per day
A-B-F B $500
F $800
C-D-E-F C $300
E $600
D $700
F $800
Total cost of crashing=300+600 x 2 + 800 + 500 x 2=300+1200+800+1000=$3300
