A New ELECTRE Method Based on Left and Right Score for Multicriteria Decision-Making

Area of Science:

• Operations Research
• Decision Science

Background:

• Multicriteria decision-making (MCDM) is crucial for system performance evaluation.
• The ELECTRE (Elimination and Choice Translating Reality) method is a widely used MCDM technique.
• Classical ELECTRE has limitations, including threshold dependency and incomplete ranking outcomes.

Purpose of the Study:

• To address the weaknesses of the traditional ELECTRE method.
• To introduce an enhanced ELECTRE approach using interval fuzzy numbers.
• To improve the completeness and accuracy of system performance rankings.

Main Methods:

• Modification of the ELECTRE method by integrating interval fuzzy numbers.
• Development of a fuzzy-based approach to handle uncertainty in decision-making.
• Utilizing left and right interval numbers for improved coordination analysis.

Main Results:

• The proposed interval fuzzy ELECTRE method overcomes limitations of the classical approach.
• Demonstrated ability to provide more complete and final rankings.
• Effectiveness validated through examples from previous research.

Conclusions:

• The interval fuzzy number approach significantly enhances the ELECTRE method.
• This fuzzy-based ELECTRE technique offers a more robust solution for MCDM problems.
• The improved method provides superior system performance ranking capabilities.
