Multi-period Objective Function

[Luqman Hakeem]

Hi!

I need to minimize my multi-period objective function.
My objective function is of the form of "z(t)" where 't' is time period (=26). I don't know how to write it in GAMS because it is showing error.
Looking forward to hear from you.

In the GAMS User's guide, you should look up three items to answer your question: summations, objective function definitions, and the use of a free variable for the objective function value that is optimized.
