Dear all,

I want to ask you guys another question for my biorefinery model, a MILP one.

I made an equation wich is applicable only to a subset of identifiers, but dont know how to put that down in GAMS. here’s the example

cddgs1(“ddgs”,k,g,t)… P(“ddgs”,k,g,t) =e= 0 (voor technologies k other than tech(k) ) ;

where k is the technology set, and tech(k) a subset of those technologies.

how to you write that down in GAMS?

second: I have a set g, a bunch of identical squared grids next to eachother. And I need to include another set of g, wich I call g’, which are other than g. so that biomass can be transported from g to g’, e.g. to calculate transport costs. the example is:

lots of thanks guys!!

greetings de benha
