I could use some help with some applescript…I think.
I need to create optimistic and pessimistic schedules.
I have one script that copies task durations to custom data & then calculates optimistic & pessimistic values, storing those in custom data keys also. This works great on both small and large projects.
set optFactor to 0.95
set pessFactor to 1.1
tell application "OmniPlan"
repeat with t in tasks of front document
if task type of t is not group task then
set myDuration to duration of t as number
set optDuration to myDuration * optFactor
set pessDuration to myDuration * pessFactor
set value of custom data entry "backup_duration" of t to myDuration
set value of custom data entry "optimistic" of t to optDuration
set value of custom data entry "pessimistic" of t to pessDuration
end if
end repeat
end tell
now I want to run an optimistic schedule, this is what I’ve got
tell application "OmniPlan"
repeat with t in tasks of front document
if task type of t is not group task then
set newDuration to value of custom data entry "optimistic" of t
set duration of t to newDuration
end if
end repeat
end tell
on projects with 20 tasks, it works, but it’s slow
with 60 tasks, you can stop for coffee
On most of my full schedules, we have 400-500 tasks. I tried it on one and gave up after 5 minutes.
question - can I “pause” the scheduling engine during a script?
- Anyone have pointers on ways to run different [user defined] simulations?
I used to do this all the time with MS proj
I trialed Merlin for a while and this was very fast.
The problem is walking through the task list. It’s just too slow.
These are construction projects, we do not use effort. The “Monte Carlo” type simulations do not give the results we are after.
