FI 300 200 250 250 50
F2 100 50 70 80 100
F3 50 5 50 10 40
Site rating 255 370 340 190
Sample calculation: 255 = 200 + 50 + 5
Looking at the above Table, it can be seen that site S2 has the highest site rating of 370.
Hence, this site would be chosen.
4.6.3 Weight-cum-rating method
This is another method of evaluating a potential location site. One can assign variable
weights to each factor. A common scale for each factor then rates the locations. The location
point assignment for the factor is then obtained by multiplying the location rating for each
factor by the factor weight. For example, rating weights of one to five could be assigned to
the three factors F1 (human resource), F2 (community facilities) and F3 (power availability
and reliability), as 5, 3, 2 respectively. Now for each of the factors, sites SI, S2, S3 or S4 could
receive 0 to 10 points as follows and the site rating could be obtained.
