a-b) Using Johnson's rule for 2-machine scheduling, the sequence is: The following set of seven jobs is to be processed through two work centers at George Heinrich's printing company. The sequence is first printing, then binding. Processing time at each of the work centers is shown in the following table: Scheduled Order Job 1 2 Job Binding (hours) 8 T 3 U 4 4 Printing (hours) 10 3 6 12 5 14 9 2 7 1 5 W X Y Z 13 11 6 7 c) For the schedule developed using Johnson's rule, the total length of time taken to complete the seven printing and binding jobs (including binding) = hours (enter your response as a whole number). d) The idle time in the binding shop based on the sequence developed using Johnson's rule = hour(s) (enter your response as a whole number). e) By splitting Job U in half, the binding machine's idle time would be cut by hour(s) (enter your response rounded to one decimal place)
