A Note on Multimachine Scheduling with Weighted Early/Late Work Criteria and Common Due Date

Algorithm 2

.
(1)Reorder the jobs by nonincreasing order of their weights, i.e., ;
(2)Enumerate all the possible partitions of the job set;
(3)for each partition
(4)do Keep the nonincreasing order of the jobs on each machine;
(5)Calculate the criterion value for this schedule;
(6)Output the best solution with the maximal criterion value;
