Question
Gestalt, Inc., uses a kanban system in its automobile production facility in Germany. This facility operates 8 hours per day to produce the Jitterbug, a replacement for the obsolete but immensely popular Jitney Beetle. Suppose that a certain part requires 150 seconds of processing at machine cell 33B and a container of parts average 1.6 hours of waiting time there. Management allows a 10 percent buffer for unexpected occurrences. Each container holds 30 parts, and 8 containers are authorized. How much daily demand can be satisfied with this system? (Hint: recall that p is the average processing time per container, not per individual part)
Explanation / Answer
Answer:
Total working hours in a day = 8 hours or 28,800 seconds
Processing time of each part = 150 seconds
Buffer time loss = 10% of 8 = 7.2 hours or 25,920 seconds
Each container takes 1.6 hours, therefore number of containers in 7.2 hours = 7.2 / 1.6 = 4.50 containers
Thus, number of parts that can be processed = 4.50 x 30 parts = 135 parts per day.
Therefore, a daily demand of 135 parts can be satisfied by the Company.
