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 On 12/20/2012 01:28 AM, Willem van Asperen wrote: > On 12/16/2012 02:06 PM, Reinis wrote: >> Country: Germany >> Company: REMAsoft (www.remasoft.com) >> Project: iC (ic.remasoft.com) >> Status: early Alpha >> Summary: We are providing a service that performs automated project >> portfolio planning.
