Weighted Shortest Processing Time gives us a total tardiness of 7.56 units which turns out to be slightly better than the random permutation.

Next let's try sorting by earliest due date.

	Name	length	readytime	due date	Weight
Job 1	1	1.4	9.48	4
Job 2	3.4	2	9	4
Job 3	3.88	2	6	3
Job 4	5	5	11	4
Job 5	5	3	10	1
