OVERVIEW	PROXIMITY	CRITERION SCORES	AHP	SUITABILITY

The Analytical Hierarchical Process (AHP) is a multi-criteria decision-making method to derive the relative weight of a number of criteria affecting for a decision to be made via the pair-wise comparison matrix. In this case, we will be applying the AHP in our decision-making for the suitable site to build the CDQC in Gombak, with the criteria being the Health Risk Factor, Accessibility Factor, Natural Conservation Factor and Economic Factor. Before utilising the AHP, the priority for the mentioned factors for the suitability map with its rationale are as follows: Order of Priority for Criteria (1 - Most Important, 4 - Least Important) Priority Number Factor Rationale 1 Health Risk When taking into account the purpose of the CDQC which would be to house those who are ill with contagious diseases, the well-being and health of the rest of the Gombak population is of the utmost importance. 2 Accessibility With the health of the unaffected Gombak population being the most important, the second would be the ease of transportation of materials during the construction phase of the CDQC and also the diseased post-construction. This is to ensure that the diseased are able to arrive at the CDQC as quick as possible, and to prevent the spread of the disease to others within the area after discovery of the disease. 3 Natural Conservation After health and accessibility comes the protection of the diseased in the CDQC from wildlife or fauna which could incur further illness and hygiene issues within both the internal and external parameters of the CDQC. 4 Economic Developmental costs are considered to be detrimental to the budget of the CDQC during its construction, but cost should not be a priority when it comes to building the facility that puts the health of its users first.
