Abstract

The paper addresses the problem of multi-slot just-in-time scheduling. Unlike the existing literature on this subject, it studies a more general criterion--the minimization of the schedule makespan rather than the minimization of the number of slots used by schedule. It gives an O(nlog驴2 n)-time optimization algorithm for the single machine problem. For arbitrary number of m1 identical parallel machines it presents an O(nlog驴n)-time optimization algorithm for the case when the processing time of each job does not exceed its due date. For the general case on m1 machines, it proposes a polynomial time constant factor approximation algorithm.
