Abstract

We present a linear programming approach to the problem of scheduling equal processing time jobs with release dates and deadlines on identical parallel machines. The known algorithm with complexity O(n 3log log n) of B. Simons schedules all the jobs while minimizing both the maximum completion time and the mean flow time. Our approach permits also to minimize the weighted sum of completion times and total tardiness in polynomial time for the problems without deadlines. The complexity status of these problems was open.
