Prescriptive optimizer to a target value.

Hi, I've been trying to create a prescriptive model that optimizes a parameter. However, I want to optimise to a particular value. I can only find the extract performance operator, but that only has maximum and minimum options. What can I use inside the prescriptive optimizer operator to do this?

Hi,

usually you just create the value

pow(value-targetvalue,2)

and then extract this value to optimize on. Similarly you can optimize on more than one value at a time.

Best,

Hi

Thank you for the response. I meant, how do I limit the maximum value? So if I'm trying to optimise x by changing a,b, and c, how do I cap the maximum value that x can be maximized to?

This is what I have so far:

Hi,

What you can do is to penalize values bigger than x like this:

optmizationValue = x - if(x>eval%{target},1e5,0)

this way you avoid values > target.
