AbstractConsider a set of n unit time jobs, each one having a release date, a due date, both nonnegative integers, and a weight, a positive real number. Given a set of m parallel machines, we describe an algorithm for finding schedules with minimum weighted number of tardy jobs. The complexity of the proposed algorithm is
$O(n^{2}frac{(1+log m)}{m})$
. The best previous algorithm for this problem has complexity O(mn3) and employs network flow techniques. Our method is based on a characterization for schedules of this type and employs graph theoretic tools.
