The following data set is Test Bed C in Guastaroba G. and Speranza M.G. "Kernel Search for the Capacitated Facility Location Problem", Journal of Heuristics, 18(6), 877-917, 2012.

There are currently 150 data files. The format of these data files is:

|J| |I|
d1 d2 d3 … d|I|
s1 s2 s3 … s|J|
f1 f2 f3 … f|J|
c11 c12 c13 … c1|I|
c21 c22 c23 … c2|I|
… … …
c|J|1 c|J|2 c|J|3 … c|J||I|,

|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;
cji (j=1,...,|J|), (i=1,...,|I|) is the cost of supplying one unit of demand of customer i from facility j.
