### Assign Values to variables

Posted:

**Mon Mar 12, 2018 10:22 am**Hey guys,

I'm a beginner, when it comes to GAMS.

I have a question about a variable. I'm right now trying to model a model of a thermal energy storage.

For this I need to use ordered sets to calculate the temperature with respect to the temperature of the time step before.

For this I implemented the set:

set i time steps / 0*720 /;

as the number of time steps.

I declared the temperature:

variable T_ti(i) input temperature of the thermal energy storage;

as a subset of i. Now I want to assign an initial value to the first value of T_ti.

How do I do this? Do I need to implement an equation for it?

Thanks a lot!

Cheers,

Max
