GAMS World Forum

hi, I would like to model a condition in my objective function. I explain the problem to make myself better understood. I would like to model how energy exchange works in place. this says that if the emergency introduced into the network (Es) is less than that taken from the network (Ep), it will ap...

I would like to go and model this constraint but I don't know how to write it on gams. the variable considered is a binary variable X (j, d, h) which is equal to one if the machinery j on day d and at hour h is active. I would like to model a constraint that tells me that if X (j, d, h) = 1 this var...
