Hi every one

I have a restriction that if x greater than delta h(n)=f(x), if x is between -delta and delta h(n)=g(x) and otherwise h(n)=k(x) that x is vareible. how modeling This limits in Gams?

Hi,

You need to use disjunctive model. To be more specific, a binary variable and a big number. Let’s consider the case if x greater than delta then h(n)=f(x) and if x is less than delta h(n)=g(x). in the following u is a binary variable and M is a big number,

x+(1-u)M>delta

x-uM<delta

h(n)=uf(x)-(1-u)g(x)

Omid,
