Question: A manufacturing facility makes a product that requires tasks A, ... , H be completed in an order that obeys a set of precedence requirements.
A manufacturing facility makes a product that requires tasks A, ... , H be completed in an order that obeys a set of precedence requirements. The following table reports the performance time in minutes/unit and the preceding task(s) for tasks A, ... , H.
| Task | Performance Time | Preceding Tasks |
|---|---|---|
| A | 4 | NA |
| B | 5 | NA |
| C | 3 | A, B |
| D | 2 | C |
| E | 7 | D |
| F | 6 | E |
| G | 8 | E |
| H | 7 | F, G |
Four line configurations are proposed:
Configuration I has four stations:
- Station 1: Tasks A and B; Station 2: Tasks C and D; Station 3: Tasks E and F; Station 4: Tasks G and H
Configuration II has three stations:
- Station 1: Tasks A, B, and C; Station 2: Tasks D and E; Station 3: Tasks F, G, and H
Configuration III has eight stations:
- Each station is assigned a single Task
Configuration IV has one station:
- Station 1 is assigned tasks A, B, C, D, E, F, G, and H
The facility operates 6 hours/day. What is the daily output for Configuration I ? Specify as a whole number by rounding. What is the daily output for Configuration II ? Specify as a whole number by rounding. What is the cycle time for Configuration III ? Specify as a whole number by rounding. What is the daily output for Configuration IV ? Specify as a whole number by rounding.
