1.A machine operator has to perform three operations, turning, threading and knurling on a number of different jobs. The time required to perform these operations (in minutes) on each job is known. Identify the sequence in which the jobs should be processed in order to minimize the total time required to turn out all the jobs also calculate the minimum elapsed time and idle time for turning, threading and knurling machines.

Job	1	2	3	4	5	6
Turning	3	11	5	2	9	12
Threading	8	1	4	6	3	6
Knurling	13	13	9	12	8	14
