Multi-Criteria Decision Matrix
Multi-Criteria Decision Matrix problems present multiple options evaluated against several criteria with different weights. You must calculate weighted scores to determine the best option. These problems test systematic evaluation and quantitative decision-making skills.

Introduction to Multi-Criteria Decision Matrix
Multi-Criteria Decision Matrix problems present multiple options evaluated against several criteria with different weights. You must calculate weighted scores to determine the best option. These problems test systematic evaluation and quantitative decision-making skills.
Prerequisites
How to Solve Multi-Criteria Decision Matrix Problems
Step 1: Identify all decision options and evaluation criteria
Step 2: Note the weight (importance) of each criterion (sum usually = 100% or 1)
Step 3: Identify the score for each option on each criterion
Step 4: For each option, calculate weighted score = Σ (criterion weight × criterion score)
Step 5: Compare the total weighted scores across options
Step 6: The option with the highest weighted score is the best choice
Step 7: Verify calculations and consider qualitative factors
Example Problem
Example: Select a software vendor. Criteria: Reliability (40%), Features (35%), Cost (25%). Vendor A scores: 9/8/7. Vendor B: 7/9/8. Vendor C: 8/7/9. Which is best? Solution: Step 1: Options: A, B, C; Criteria: Reliability(0.4), Features(0.35), Cost(0.25) Step 2: Vendor A = (9×0.4)+(8×0.35)+(7×0.25) = 3.6 + 2.8 + 1.75 = 8.15 Step 3: Vendor B = (7×0.4)+(9×0.35)+(8×0.25) = 2.8 + 3.15 + 2.0 = 7.95 Step 4: Vendor C = (8×0.4)+(7×0.35)+(9×0.25) = 3.2 + 2.45 + 2.25 = 7.90 Step 5: Highest = Vendor A with 8.15 Answer: Vendor A
Pro Tips & Tricks
- Weights usually sum to 1 (or 100%) - verify before calculating
- Convert percentage weights to decimals for easier calculation (40% = 0.4)
- Create a table with rows as options and columns as criteria for clarity
- Calculate partial sums to verify accuracy
- Scores are typically on a scale (e.g., 1-10, 1-5, or 0-100)
- The highest weighted score indicates the mathematically optimal choice
