Rockness Recycling refurbishes rundown business students. The process uses a moving belt, which carries each student through the five steps of the process in sequence. The five steps are as follows:
STEP | DESCRIPTION | TIME REQUIRED PER STUDENT |
|
1 | Unpack and place on belt | 0.2 | minute |
2 | Strip off bad habits | 0.4 | minute |
3 | Scrub and clean mind | 0.6 | minute |
4 | Insert modern methods | 0.8 | minute |
5 | Polish and pack | 1.0 | minutes |
One faculty member is assigned to each of these steps. Faculty members work a 40-hour week and rotate jobs each week. Mr. Rockness has been working on a contract from General Eclectic, which requires delivery of 2,500 refurbished students per week. A representative of the human resources department has just called complaining that the company hasn’t been receiving the agreed-upon number of students. A check of finished goods inventory by Mr. Rockness reveals that there is no stock left.
a. Calculate the maximum output for each step.
b. Which step is the bottleneck?

step4
a.
Ans -
Max Capacity = 40 hrs x 60 mins = 2400 minutes
Step 1 - minute unpack and place on belt
Time required per student = 0.2 min
Max. Output = 2400/0.2 = 12,000 students per week
Step 2 - strip off bad habits
Time required per student = 0.4 min
Max. Output = 2400/0.4 = 6,000 students per week
Step 3 - scrub and clean mind
Time required per student = 0.6 min
Max. Output = 2400/0.6 = 4,000 students per week
Step 4 - insert modern methods
Time required per student =0.8 min
Max. Output = 2400/0.8 = 3000 students per week
Step 5 - polish and pack
Time required per student =1 min
Max. Output = 2400/1 = 2400 students per week
b.
Ans -
Bottleneck: Least capacity in process = STEP 5
Process cannot create > what bottleneck is, so 2400 is max
capacity for process as a whole.
