Hello Willem, hello folks,
here are some of fun-facts from our current system:
- Planner -
1 planning entity
2 planning variables
15 hard and soft constraint rules
- Size of initial Problem (example) -
20 Projects totaling 5000 man-hours
40 resources totaling in 13,3 man-years of availability
240 intervals รก 4 hours per project and resource to be "walked" through
This results in a problem space for this example of 6.9 x 10^4977
- Solving -
hardware: single core server with 4GB total RAM
execution time: 26 minutes (all hard constraints met and solution score
hasn't improved for 100 steps)
used ram: 350 MB - 360MB
used cpu: 50% - 60%
used solution algorithm: simulated annealing and tabu search
I hope this helps.
kind regards
Reinis

That's a great testimonial!
Just a question: can you give us any idea of the size of the problem you
are solving? For instance, the number of planning entities, planning
variables or number of values for these variable?

Willem
