Hi
A few remarks:

• The chance getting an answer is higher if you post your question in English.
• If you submit your model, please attach it (or enter it as code), so the formatting remains as it is. If you don't, people willing to answer your question may lose a lot of time reformatting your code.

Now your question: Gams states in the explanation that you can't use uniform in an equation. Here you can find more information on what is allowed in equations.
The way to solve this in your case is to define a parameter and assign it a uniform value and replace the uniform in your objective values by this parameter:

Code: Select all

parameter puni 'Uniform value';

puni = uniform(0,1);
...

ObjFinal.. zfinal=e=((0.0002936*(puni-967))
