2. SCHEDULING ISN'T ROCKET SCIENCE
It’s harder

3. SCHEDULING ENGINE COMPARISON: GANTT CHART
Unlimited Resource Critical Path
Resource Limited Critical Path
Aurora
Slide shows the resource-constrained critical path of the SAME project, but the shortest path (white boxes) shows the critical path when there are unlimited resources.
The blue boxes shows the resource-constrained critical path when the resources are modeled and resource leveled,
The orange boxes shows the EXACT SAME project with the exact same resources but using intelligent scheduling with Aurora.
NOTE that there are many more tasks in the model, but only the longest chain is shown in each case so it can be visualized.

This slide shows that there are many examples in the literature that show the effect of using different scheduling algorithms on the final duration of the schedule.

5. CONSTRAINTS ADD COMPLEXITY
Technical constraints (E.g., F-S, F-F, S-F, lags)
Resource constraints
Labor constraints
Equipment, Tools (e.g., cranes)
Usage constraints – e.g., tool can only be used for so many hours continuously &/or during a day.
Spatial / physical space constraints – e.g.,
job requires a certain location or type of space
two elements should (or should not) be next to each other
Ergonomic constraints – individual limitations on work conditions

6. MS PROJECT RESULTS (BEGINNING OF ANIMATION) VS. AURORA RESULTS (END)
The animation shows the transition of the Gantt chart from Microsoft Project, with a histogram of one of the resources, to the gantt chart from Aurora with a histogram of the the same resource.
The Aurora results are significantly shorter and the histogram is much flatter.
So a better schedule in every aspect.
