Objective

To identify a suitable location for building a National Communicable Disease Quarantine Centre, by using of analytical hierarchy process.

Part 1: Visual Analysis on Map View

Natural Factor

Ultimately, "water" and "park" are locating near to residents area and they are represented by blue and green color respectively. And "forest" is located at the right side of the graph, and it is represented by orange color. Due to majority of the natural features are near to residential area. Thus, natural factor should be considered together with residential area.

Health Risk Factor

Avoiding residential area is a most important factor to consider. Due to the possibility of leakage of dangerous virus from building and cause disaster. From the generated graph, we can easily notice that, after exclude residential area (Green color polygon the graph). There are quite large of the space for us to consider while propose (mainly bottom and right part of the graph). As mentioned above, natural features are near to residential area. Thus, natural factor is weighted as 1 (least important), but health risk factor is weighted as 9 (most important).

Accessibility Factor

Finding areas that near to service and track roads will ensure the transportation of construction material, and lead to earlier TOP of the building. As mentioned above, after removing of natural features and residential area, we will only have bottom part of the Gombak to consider. However, as the service road and track road is not reaching to every corner of Gombak. Therefore, we should try to look at the area that beside service roads and track road.
