Hi! I want to ask, is there anyway to create a list (or a set) inside of a set? I am dealing with
and I don’t know how to formulate the Kqjk. What I am thinking is, i is element of Kqjk and Kqjk is element of q, therefore index i is element of q. Does anyone have any suggestions?
Many Thanks!
Hi
It would be easier to answer if you would provide the code with the actual elements in those sets.

Hi @Renger, this is the full code that I want to use:
zi and yq represent binary variables, in which if zi = 1, a service station is built at node i, 0 otherwise. and if yq = 1, flow on path q is feasible.
Basically I have all the data that is needed (the nodes, arcs, potential facility locations, and number of stations to be located). It is just I am really confused on how to integrate the q with Kqjk.
