How do you make a variable have a consistent value across time?
How to make a constraint that will make a variable equal to a previous value like
var(n,t) = var(n,t-1)
How can you model differently the 9 and 10th constraint?
The main function of those constraint are a switch-like event. The constraints ensure that the binary variables for both set will be open, run for a number of time, and then stop.
The main difference between the two are for the letter set, the binary variable should be open right from the start which means the binary variable must be equal to 1 at time = 1.
How can you model this differently?
Attached are the additional info about the AIMMS model.
