(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Hi,
I'm trying to set up a Primavera Project for a future sensitivity/Monte Carlo analysis, therefore, I need to automatize the current schedule.
I have two activities running in paralell. Activity 1 is shorter than activity two and once it finishes, its resource can go support Activity 2. Therefore, only when Activity 1 finishes, the progress rate of Acitivity two changes from R2 to R1+R2. Also, the works performed by R1 in Activity 2 require a third activity afterwards. This means that the units where R1 worked (R1*(T2-T1)) will have to be used in a new activity, 3, with a new resource (R3).
Is it possible to do in Primavera automatically, so when the progress rate of the resource change, so do the duration of all activities?
Thanks!

This we call variable resource assignment. In construction jobs this is done on an everyday basis. This must go side to side with good reporting as you will need the daily details you must communicate to the field. The following example is so simple that the details can be shown as part of the Gantt, in real life scenarios you will usually need a tabular report.
Multiple productivity assignments is done at the resource level, this requires considering volume of work an essential element of production rates, the volume of work per unit time.
This can be modeled in Spider Project and you can also run sensitivity/Monte Carlo there.
Let me know if you will need the details.
Pablo,
This cannot be done. P6 cannot dynamically change the "unts per time period" of an activity. P3 could perform what it called "Stretching and crunching" when it resource levellled a plan, but it could only choose a new units per time period at the start of an activity not as a response to another one finishing.
There is also no way to dynamically re-assign units between activities.
All I can suggest is to granulate the work more finely, so that you have many more activities. Then use levelling.
I keep hearing that it is not possible, could you elaborate a little more on how it could be done?
The other way I was thinking on how to solve is:
To do this however, I'd have to dynamically assign the total units to be completed to 2b, from the one that couldn't be completed in the time frame of 2a. Is this possible? If so, how do you do it?
Thanks!
if you make the activity type resource dependent yes
