Five jobs are to be run—first on process I, then on process II. The jobs are listed in the following table with their time requirements on the two processes.

(a) Sequence the jobs by Johnson’s method so that the total flow time and idle time will be minimized.

(b) Show the sequence and durations on a bar chart, and indicate how long after the start of the first job until each job will be completed.
