Gantt Chart with (minimum) 2 options per
activity:

With tccB01 (.MPP file), you have access to utility data
for activities
|
Normal Duration and Crash
Duration
|
User can import activities with preloaded utility
data of <= 20 options per activity
|
Normal Cost and Crash Cost
|
User can define their own utility options or make
use of preloaded options.
|
Indirect time-related overhead cost per
Project
|
Privacy of utility data available if User assigns
percentages rather than actual durations and
costs
|
Userform with options to plot your TimeCostCurve
For example, in this case, user input ‘-4’ to shorten the project by
4 days |

Resulting TimeCostCurve, with these notes
Indirect costs assumed to be $850/day is not large enough to
reduce the total project cost as it’s duration is being
compressed.
To compress by 2 days, activity ID 11 (Install Equipment) is
compressed
To further compress by 2 more days, activity ID 8 (Set
Foundation) is compressed
To further compress by 1 more day, activity ID 5 (Dig Cable
Trench) is compressed
To further compress by 3 more days, activity ID 14 (Lay Control
Cable) is compressed
To further compress by 1 more day, activity ID 17 (Remove
Equipment) is compressed
To further compress by 2 more days, activity ID 4 (Mobilise) is
compressed
All-Normal schedule is 58 days, $375,620
VS Fully-crashed schedule is 47 days, $445,837
