Homework Answers
Cycle Time = Available Time / Number of units = 480/40 = 12 mins/unit
Let us first find the number of followers for each task -
| Task | #Follower |
| A | 8 |
| B | 5 |
| C | 3 |
| D | 3 |
| E | 2 |
| F | 2 |
| H | 1 |
| G | 1 |
| I | 0 |
This is in sorted order (C will be before D, E will be before F and H will be before G due to larger time)
Theoretical minimum number of workstations required = sum of total task times/cycle time
= (10+11+5+4+12+3+7+11+3)/12 = 5.5 or 6 (rounded)
Balancing the line -
| Workstation | Tasks | Total Time |
| I | A | 10 |
| II | B | 11 |
| III | C, D | 9 |
| IV | E | 12 |
| V | F, G | 10 |
| VI | H | 11 |
| VII | I | 3 |

EXAMPLE 8.2: Assembly-Line Balancing The Model J Wagon is to be assembled on a conveyor belt. Five hundred wagons are required per day. Production time per day is 420 minutes, and the assembly steps and times for the wagon are given in Exhibit 8.9A. Assignment: Find the balance that minimizes the number of workstations, subject to cycle time and precedence constraints SOLUTION I. Draw a precedence diagram. Exhibit 8.9B illustrates the sequential relationships identi- fied in Exhibit 8.9A. (The length...
