Cyclone Appliances has developed a new European-style convection oven that will be made on an assembly line. The schedule requires 96 ovens in an 8-hour day. The assembly includes 7 tasks. The table below indicates the performance time and the sequence requirements for each task.
Use the longest task time rule
What is the effienciency of the line?
a. 100 % b. 50 % c. 75 % d. 37.5 % e. 90 %
What is the total idle time?
a. 0 b. 1 c. 3 d. 4 e. 5
Please workout problems so I know how to do them
| Task | Performance Time (minutes) | Task must follow task listed below | 
| A | 1 | |
| B | 2 | A | 
| C | 3 | B | 
| D | 2 | B | 
| E | 4 | C,D | 
| F | 1 | E | 
| G | 2 | F | 
Solution
Cycle time = Total working time / total outputs
= (8 * 60) / 80 = 480 / 80 = 6 min
Minimum number of workstation = Total Performance Time / Cycle time
= 15 / 6 = 2.5 = 3 work station
