The 0/1 uncapacitated facility location problem with two objectives is defined as follow:
Min sum{i=1,...,nI;j=1,…,nJ} c1(i,j) x(i,j) + sum{j=1,…,nJ} r1(j) s(j)
Min sum{i=1,...,nI;j=1,…,nJ} c2(i,j) x(i,j) + sum{j=1,…,nJ} r2(j) s(j)
s/t sum{j=1,…,nJ} x(i,j) = 1 for i=1,…,nI
x(i,j) <= s(j) for i=1,…,nI; j=1,…,nJ
x(i,j) = 0 or 1 for i=1,…,nI; j=1,…,nJ
s(j) = 0 or 1 for j=1,…,nJ
