% split node (after optimization)

[Gerda]

Good morning  ..  Please help 

In my diagram,  have an available contact base of 272,251 customers 

and I'm using a percentage split node 34% and 66%

In my campaign group, I have specified a required count on campaign level of 60,000

I also have a cellsize constraint of 60,000 in my scenario on campaign_cd

I need an end result (after optimization) with a total of 60,000 customer that is split accordingly to the above specifications  ?

Are you BY any chance using CI Studio or any other of product in the CI/MA offerings?
Also, what have you tried so far?

[Gerda]

hello  ..  yes, i am using Customer Intelligence Studio, Version 6.3

I have tried to limit my campaign's overall cellsize to 60000 in the Campaign Group

I have also added a Contraint in my senario but it doesn't seem to work

I have attached a document (first message)

Thanks for your help  🙂

What exactly are you trying to achieve - do you want these 60000 to be split between these two cells as 1:2?     Since you know the total count, you also know that this will mean 20.000 and 40.000 counts in the cells.  You can enable two cell-level constraints instead of one campaign-level aggregate constraint.

This functionality is being considered for a future release, but for now the only reliable way to accomplish it is to have a post-process node handle it in code, or put a linkable cell node after the optimized communication node and do your split by percentage in a follow-up (non-optimized) campaign (link > split > cell/cell > comm).

If you try to force the logic into your optimization scenario, you'll either:

• have potentially biased results (since the higher value customers will likely go into the larger cell, since that will result in a higher objective value)
• get an undesired result (if the input size is < 60,000 total and you specify 40,000 and 20,000 respectively as maximum constraints) since there's no guarantee the split cells will have the correct ratio
• have infeasible constraints (if your input size is < 60,000 and you try and specify 40,000 and 20,000 respectively as minimum constraints for two other cells)
• have to frequently maintain the results (if the "main" cell size changes from 60,000)
