Hi,

I have been working on series of simple GAMS equation but was stumbled upon a specific equation regarding time horizon implementation in the equation. The equation below show a specific decision variable equation where the time horizon maybe a week or months is to be implemented. I would appreciate some help regarding, how to formulate such time horizon in GAMS? in other word How to write the equation in GAMS?

∑_t∑_i(C_it x_it )
