PROBLEM II: In an assembly line, there are 7 workstations, as shown below. In row 1, you are given the processing times in minutes. Row 2 gives the workstation number. Assume an 8-hour (480-minute) work day.

6.1 3.2 8.4 2.5 20.0 1.4 1.7 1234567

(6) The output capacity of the assembly line is:

(a) 40 (b) 24 (c) 16 (d) 20 (e) none of the above

(7) The percent of idle time (rounded to 2 decimal places) is: (a) 69.07 (b) 32.39 (c) 34.25 (d) 36.40 (e) none of the above

(8) If the desired output rate is 20 units per day, the minimum number of workstations needed is: (a)3 (b)2 (c)5(d)4 (e)6 (b) Noneoftheabove

(9) If the desired output rate is 20 units per day, the target cycle time is:

(a) 32 minutes (b) 24 minutes (c) 30 minutes (d) 48 minutes (e) none of the above

Re-organize the workstations so that you can produce at least 20 units, while minimizing the idle time (10) After the re-organization, the percent of idle time (rounded to 2 decimal places) is:

(a) 12.84 (b) 9.39 (c) 6.28 (d) 2.48 (e) none of the above
