weighted ranking tool to

mathematically and analytically

determine which of these solutions is

best. To do this, build a weighted

ranking matrix for the problem using

the following guidelines: Develop a list

of criteria. Assign a weighted

percentage to each of the decision

criteria based on importance. The total

of all listed criteria must equal 1.0 (i.e.,

the total of the assigned criteria or <

0.2 Criterion 3 = 0.4 Criterion 4 = 0.1

Therefore, 0.3 + 0.2 + 0.4 + 0.1 = 1.0 or

100% Compare each solution to each

criterion, and assign a numerical rating

scale to each alternative. For example:

1 = the solution does not meet the

criterion very well, and 5 = the solution

does meet the criterion very well.

Evaluate and rate each solution

against each criterion by multiplying

the rating scale number by the

weighted numerical criteria number.

(e.g., the weighted criteria is 0.3 x 5 =

1.5. This is the criteria number 0.3

times the assigned alternative rating

scale number of 5). Add the weighted

values and calculate the final score for

each proposed problem solutions.

Select the alternative with the highest

score.
