1 Line Balancing Problem 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

2 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

3 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 ( ) 4.1x % %=30.3% Balance Delay

5 Number of Work Stations (bottleneck) = 4.88 work stations

6 Line Balancing Solution A B C 4.1 D 1.7 E 2.7 F 3.3 G 2.6 Station 1 Station 2 Station 3 Station All under 6 minutes? (6.0) (5.6) (5.8) 4 Stations 20/24=83.3% Max prod./hour 60/6 10 units/hour

7 Line Balancing Problem 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 /5.6x5 = 20/28 = 71.4% 5 Stations Max Prod./hour 60/ units/hour

8 40 secs 59 secs 84 secs 34 secs 56 secs 45 secs What is the minimum # of work stations? Round down. A.3 B.2 C.4 D.5 E.6

9 = /84 = 3.78 or 3 work stations What is the efficiency with 6 operators? 318/6 x 84= 318/504 = 63%

10 40 secs 59 secs 84 secs 34 secs 56 secs 45 secs 99 secs 118 secs 3 Stations ? 318/3x /354 = 89.8% 101 secs

11 40 secs 59 secs 84 secs 34 secs 56 secs 45 secs 4 Stations? 99 secs 84 secs 56 secs 79 secs 318/4 x 99 = 318/396 = 80.3%
