Knowledge that Transforms

Communications are read for interest in issues that have importance for all who practice and use management science. They are not refereed for technical correctness, as are articles and Notes that appear in Management Science. The reader is therefore cautioned that the publication of any Communication implies neither scientific standing nor acceptance per se on the part of either Management Science or TIMS.
