i and k is a facilities..facilities i and facilities k... j and q is a location...location j and location q ... f (i,k) mean flow between facility i and k.. d(j, q) mean distance between facility j to q

The physical meaning of the variables does not matter, but if they are e.g. vectors, functions, of the loop counters. The initial "min z" could mean a variety of things also.

Currently all we see is a notation, which is not valid Matlab code and not an exact mathematical notation also. Then translating this into valid Matlab code must be based on guessing. Please edit your question and post the information in a unique and unequivocal way.
