The present layout is:
A | B | C | D |
with a distance of 10 feet between adjacent areas.
Computing the Load * Distance measure:
| Load * Distance | |
A to B | 7 * 10 | 70 |
A to C | 193*20 | 3860 |
A to D | 12*30 | 360 |
B to C | 4*10 | 40 |
B to D | 82*20 | 1640 |
C to D | 222*10 | 2220 |
Total | | 8190 |
Develop a preferred layout. What is the sum of the loads * distance of your new layout?
A firm must produce 40 units/day during an 8-hour workday. Tasks, times, and predecessor activities are given below.
Task | Time (Minutes) | Predecessor(s) |
A | 2 | - |
B | 2 | A |
C | 8 | - |
D | 6 | C |
E | 3 | B |
F | 10 | D, E |
G | 4 | F |
H | 3 | G |
Total | 38 minutes | |
Determine the cycle time and the appropriate number of workstations to produce the 40 units per day.
