Questions? 1. What is the bottleneck? 2. What is maximum production per hour? 60/4.1=14.63 units 3. What is efficiency and balance delay? 4. How to minimize work stations? 5. How should they be grouped? 6. New efficiency? 4.1 minutes

Calculate efficiency A. 73.2% B. 56.7% C. 69.7% D. 79.6% E. 81.2% A B C 4.1mins D 1.7mins E 2.7 mins F 3.3 mins G 2.6 mins 2.2 mins 3.4 mins

( ) 4.1x % %=30.3% Balance Delay

Number of Work Stations (bottleneck) = 4.88 work stations
