Which solution should be chosen according to the completed weighted-ranking matrix?

This is because it has the highest score in the “Lower maintenance cost” category, which has a weight of 2, and the second highest score in the “Improved customer satisfaction” category, which has a weight of 3. The weighted-ranking matrix is a technique that helps to compare and evaluate different options based on multiple criteria and their relative importance. Each option is assigned a score for each criterion, and the score is multiplied by the weight of the criterion. The option with the highest total score is the most preferred one.
