Using the Decision Wizard in IDRISI, the standardized results of the factors and well as the two constraints the Multi-Criteria Evaluation can be implemented (MCE). As addressed in the Introduction page, Weighted Linear Combination(WLC) would be performed on the factors. For this analysis, the suitability level for the region depended on the weights that were assigned for each factor in comparison to each other. The factors could have been weighted in three potential ways. These include assigning Equal weights to all the factors, using user-defined weights which are relative weights entered by the user or using the Analytical Hierarchy Process (AHP). AHP involves utilizing the Weight module to conduct a pairwise comparison of relative importance of one factor to another factor. Using this method the weights of each factor can be derived. The image below (Image 1) represents the AHP weight derivation.

For the pairwise comparison these were the values assigned due to several reasons. Research into the topic as discussed in the Background page along with interviewing immigrants aided in developing an understanding of which factors are more important in comparison to others. Rent seemed to be of highest importance thus, for the AHP, rent was assigned the highest values in comparison to other factors. After rent, bus routes were also assigned a higher comparison factor which was slightly less than that of rent. The comparison factors of sky-train proximity and shopping centre distance were similar values. Residential type reference was assigned comparison values less than the before mentioned factors. The distance to libraries factor was assigned the lowest values in terms of comparison to other factors. This is because in comparison to the other factors, new immigrants would consider this factor of less importance. The weights derived from the AHP is displayed in the table below.

From the table above, one can observe that the rent factor has the highest weight value. Thus when the MCE is completed, the result would exhibit more weight on the rent factor. On the other hand, Proximity to Libraries has the lowest weight value. This indicates that in the MCE, closeness to libraries would not be of high significance. In addition The Consistency Ratio attained from this process has a value of 0.07. This is an acceptable value since a consistency ratio value below 0.1 is considered acceptable. This consistency ratio indicates that the pairwise comparison conducted was of acceptable quality.

The MCE results are displayed in the image below (Image 2). It indicates that the highest level of suitability is the value of 205. This means that there is no region within the GVRD that has a perfect level of suitability for new residents to live in.
