Answer :
Path duration:
A-B-F-J-K =25 days (critical path)
A-B-E-H-K = 23 days
A-C-F-H-I-K = 24 days(sub critical path)
A-DG-J-K = 20 days
A-B-F-J-K = 23 days
18) Normal cost of the project = direct cost of all activities + overall cost of critical path
= 800+1000+300+400+100+500+1200+350+700+500+450+(200*25)
=6300+5000
So, Normal cost of the project = $11300
19)After calculating path slope ,we found slope I has least cost slope of 75 in path A-B-F-J-K.So,we will crash cost slope I by one day,
New Total cost = 11300+75-200 = $11175.
We have two critical bath(A-B-F-I-K and A-C-F-I-K).I has found common in both the paths
Boe,crash cost slope of I by one more day.
Now,Total cost = 11175+75-200 = $11050.
Hence,Cost of the project after 2 days shortening = $11050.
20) Crashing cost per day for activity G = Cost Slope of G = 1400-1200/8-4 = 50.
Crashing cost per day for activity G = $50.

Question 16 4 points Save Answe The following provides information about a project, including a list of activities and precedence relationships, activity durations (normal and "crash" times), direct activity costs (normal and "crash"), indirect costs for the project, as well as calculated crash costs/day and the maximum amount that each activity can be shortened (crashed) by. There are no penalty costs for this project. Total project cost (using normal times), a network diagram, and the four paths and durations have...
