A new additive ratio assessment aras method in multicriteria decision making

A very specific and technical topic!

Here's a breakdown of the concept:

Additive Ratio Assessment (ARA) Method

The Additive Ratio Assessment (ARA) method is a multicriteria decision-making (MCDM) approach that helps evaluate and rank alternatives based on multiple criteria. It's a relatively new method, introduced in the 2010s, which aims to overcome some limitations of traditional MCDM methods.

Key Features of ARA Method

  1. Additive: The ARA method is based on an additive aggregation function, which means that the overall score of an alternative is calculated by summing up the scores of each criterion.
  2. Ratio: The method uses a ratio-based approach to evaluate the performance of each alternative on each criterion. This means that the scores are normalized to a common scale, typically between 0 and 1, to facilitate comparison.
  3. Weighted: The ARA method allows for the use of weights to reflect the relative importance of each criterion. These weights are used to calculate the overall score of each alternative.
  4. Non-linear: The ARA method can handle non-linear relationships between the criteria and the alternatives, which is particularly useful when dealing with complex decision-making problems.

Advantages of ARA Method

  1. Flexibility: The ARA method can be applied to a wide range of decision-making problems, including those with multiple criteria and alternatives.
  2. Robustness: The method is robust to outliers and noise in the data, making it suitable for real-world applications.
  3. Interpretability: The ARA method provides interpretable results, as the scores are based on a clear and transparent calculation process.

Applications of ARA Method

  1. Environmental decision-making: The ARA method has been applied to environmental decision-making problems, such as evaluating the sustainability of different land-use scenarios.
  2. Healthcare decision-making: The method has been used in healthcare decision-making, for example, to evaluate the performance of different treatment options.
  3. Business decision-making: The ARA method can be applied to business decision-making problems, such as evaluating the performance of different investment opportunities.

Limitations of ARA Method

  1. Complexity: The ARA method can be computationally intensive, especially when dealing with large datasets or complex decision-making problems.
  2. Subjectivity: The method requires the use of weights and normalization parameters, which can be subjective and influenced by personal biases.
  3. Sensitivity to data quality: The ARA method is sensitive to the quality of the data used, and poor data quality can lead to inaccurate results.

In summary, the Additive Ratio Assessment (ARA) method is a powerful multicriteria decision-making approach that can be applied to a wide range of decision-making problems. While it has several advantages, including flexibility, robustness, and interpretability, it also has some limitations, such as complexity, subjectivity, and sensitivity to data quality.
