PROBLEM I: 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.

5.6 4.7 6.4 6.8 10.0 7.3 2.9 1234567

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

(a) 32 (b) 40 (c) 36 (d) 48 (e) none of the above

(2) The percent of idle time (rounded to 2 decimal places) is:

(a) 27.84 (b) 32.39 (c) 49.29 (d) 37.57 (e) None of the above

(3) If the desired output rate is 32 units per day, the minimum number of workstations needed is: (a)2 (b)3 (c)4(d)5 (e)6 (b) Noneoftheabove

Re-organize the workstations so that you can produce at least 32 units, while minimizing the idle time. (4) After the re-organization, the output capacity of the assembly line is:

(a) 30 (b) 32 (c) 24 (d) 36 (e) None of the above

(5) After, the re-organization, the percent of idle time (rounded to 2 decimal places) is:

(a) 13.84 (b) 24.39 (c) 17.23 (d) 8.56 (e) none of the above
