As per the details provided in the network diagram and the matrix, the Normal Cost is $2075 for activity A to G. To calculate the expedite cost slope for activities A to G we have used the formula of (Normal Cost – Crash Cost) ÷ (Normal Time – Crash Time). Expedite cost slope is extremely important as it is used to calculate the minimum cost that is used to evaluate the critical paths. The below are the critical paths as per the above network diagram that can be derived.
    Critical Paths
    Length of the Critical Paths
    A-B-E-G
    25
    A-C-E-G
    19
    A-C-F-G
    20
    A-D-F-G
    24
As per the four critical paths we have added the normal time for each of the activity of the critical paths in order to find the length of the critical path. For example: The length of critical path of A-B-E-G was derived by adding 5+8+3+8 = 25 and similarly for the other three critical paths. We can observe that the length of the critical path A-B-E-G was the highest with 25 while the length of critical path A-C-E-G was the lowest with 19. Our aim is to reduce the critical path with highest duration of 25 by...
