[Help-glpk] facility location problem

[Pedro Ivo Dantas]

Hello,

I'm trying to solve the facility location problem (flp) with glpk, but
i'm stuck. Since this problem has two objectives, minimizing the
number of conections between facilitys and clients and the number of
open facilitys, how can i model it?
Any help would be appreciated.

Thanks
