Supply Chain Management Class:
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 1: Unpack & place on belt 1 minute
Step 2: Strip off bad habits 1.5 minutes
Step 3: Scrub & clean mind 0.8 minute
Step 4: Insert modern methods 1 minute
Step 5: Polish & pack 1.2 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 Electric, which requires delivery of 2,000 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. What is going on?
Answer:
Max Capacity = 40 hrs x 60 mins = 2400 minutes 2400/students 1 minute unpack, place on
belt 1600/students 1.5 strip bad habits 3000/students .8 scrub/clean 2400/students 1 insert
2000/students 1.2 polish Bottleneck: Least capacity in process = STEP 2 Process cannot
create > what bottleneck is, so 1600 is max capacity for process as a whole. Between steps
1 and 2, 800 students backed up.
