There are currently 150 data files. The format of these data files is:
s1 s2 s3 … s|J|
f1 f2 f3 … f|J|
c11 c21 c31 … c|I|1 c12 c22 c32 … c|I|2 … c1|J| c2|J| c3|J| … c|I||J|
|J| is the number of potential facility locations;
|I| is the number of customers;
di (i=1,...,|I|) is the demand of customer i;
sj (j=1,...,|J|) is the capacity of facility j;
fj (j=1,...,|J|) is the fixed cost of opening facility j;
cij (i=1,...,|I|), (j=1,...,|J|) is the cost of supplying one unit of demand of customer i from facility j.
