Evaluation of a vendor (out of 10)

Question

The criteria Cost, Quality, and Delivery have weights 2, 5, and 3 respectively. What is the vendor's weighted average score?

Solution

1. Weighted sum = 6 x 2 + 9 x 5 + 8 x 3 = 12 + 45 + 24 = 81.
2. Sum of weights = 2 + 5 + 3 = 10.
3. Weighted average = 81 / 10 = 8.1.
