Star-Tec Manufacturing aims to redesign its aerospace components manufacturing facility to improve efficiency and reduce costs. The facility consists of nine departments of equal size. The following table presents the estimated flows among the departments:

| | A | B | C | D | E | F | G | H |
|---|----|----|----|----|----|----|----|----|
| A | - | 50 | 10 | 25 |100 | 10 | 40 | 20 |
| B | 20 | - | 40 | 25 | 90 | 0 | 40 | 20 |
| C | 15 | 30 | - | 40 | 50 | 10 | 0 | 0 |
| D | 0 | 60 | 10 | - | 15 | 75 | - | - |
| E | 30 | 30 | 10 | 20 | - | - | - | - |
| F | 0 | 40 | 20 | - | - | - | - | - |
| G | 25 | 40 | 20 | - | - | - | - | - |
| H | 1 | - | - | - | - | - | - | - |

Current layout of the facility is shown below:

```
A B C
D E F
G H I
```

Dimensions: 200 ft by 200 ft.

Tasks:
1. Develop an Activity Relationship Chart based on the From-To chart provided.
2. Develop a Space-Relationship Diagram for the operation.
3. Evaluate the current layout using the "Distance Traveled by Product" technique discussed in class (use rectilinear distance in all calculations).
4. Develop two layout improvement alternatives.
5. Evaluate the alternatives using the "Distance Traveled by Product" technique (use rectilinear distance in all calculations).
6. Make a layout recommendation based on the evaluated alternatives.

Answer :

Final answer:

Developing an Activity Relationship Chart and a Space-Relationship Diagram, evaluating the current layout using 'Distance Traveled by Product' technique, creating layout alternatives and then comparing these can guide layout redesign for improved manufacturing efficiency.

Explanation:

In the quest for improving efficiency and reducing costs, the manufacturing layout redesign at Star-Tec Manufacturing should be informed by a detailed analysis of the current situation and a structured approach to developing and evaluating alternatives. This is typically an exercise in Operations Management, specifically within the realm of facility layout planning.

  • Firstly, an Activity Relationship Chart can be developed based on the From-To chart provided, with frequent interactions among department depicted as close relationships.
  • Secondly, a Space-Relationship Diagram may be developed based on the Activity Relationship Chart, choosing a suitable scale and placing departments with close relationships near each other.
  • Thirdly, the current layout is evaluated using the Distance Traveled by Product technique, by calculating the summed rectilinear distances that products travel between each pair of departments, multiplied by number of inter-departmental product flows.
  • Fourthly, layout improvement alternatives can be developed based on the analysis of the Activity Relationship Chart and Space-Relationship Diagram, whilst aiming to reduce the cost associated with the distance traveled by the product.
  • Finally, these alternatives are evaluated using the same technique employed to evaluate the current layout.

The best alternative is selected based on the evaluation and recommended for implementation thus leading to improved Manufacturing efficiency.
