Need advise on modeling an usecase

Hello Experts, Need some advise on how to model an usecase we have got. I am sure you would have come across a case similar to this, wondering how you solved it.

Let’s say a process has to perform credit score on an application. Each application can have more than one applicant. For each applicant process has to calculate AgeScore & IncomeScore. At the end of the process we have to get an average of each applicant score. Any idea, what is the most elegant way to model something like this. Please see the attached screenshot to get a better idea of what I have in mind.


Thanks for your time.
