I’m having trouble with variables that the model chooses to give them very small values but not zero, values that are not reasonable for these variables. My question is how can I give the model a range for these variables such that: on the one hand they can be zero and on the other hand they can not be for example smaller than 0.1? Something like: x=0 or x>0.1.
Currently, these variables are defined as positive variables.

Thank for your response.
I’ll try to make it clear.

Since small values for one of the variables in my model are causing an infeasible solution, I’m looking for a way to solve this problem.
However, a simple restriction like X>1 is inapplicable because I want to give this variable the option to be zero. Therefore, I’m trying to give this variable a specific range like:
X=0 or X>1 but I don’t know how to do so.
In other words, what I’m trying to do is to create a specific range in which one of my variables can be changed. This range is not continuous. The first part is zero (only one value), and the second part is all the values above 1.

I hope my problem is clear now.
Thank you again for the willingness to help, I really appreciate it!
