# Understanding  Multi-criteria Analysis

Multi-criteria analysis is a decision-making technique that is used to evaluate multiple options based on several criteria. It is also called multi-criteria decision analysis, multi-criteria decision making methods, multi-criteria evaluation techniques, multi-criteria optimization models, or multi-criteria decision support systems. This approach helps individuals and organizations make informed decisions when faced with complex choice problems.

## What is Multi-Criteria Analysis?

Multi-criteria analysis refers to a set of methods used to evaluate alternatives while considering multiple criteria under conflicting interests. It involves mapping the decision problem, defining the criteria used to evaluate each alternative, and assessing the relative importance of each criterion.

## How does Multi-Criteria Analysis work?

Multi-criteria analysis works by ranking alternatives based on different criteria and then aggregating these rankings to produce an overall score for each alternative. This approach allows decision-makers to consider all relevant factors and weigh them according to their relative importance.

## What are the benefits of Multi-Criteria Analysis?

Some key benefits of using multi-criteria analysis include:

• Providing a structured framework for complex decisions
• Encouraging transparency in the decision-making process
• Ensuring that all relevant criteria are taken into account
• Allowing for subjective judgments to be integrated into the decision-making process.

## Where can Multi-Criteria Analysis be applied?

Multi-criteria analysis can be applied in various fields such as business, engineering, health care, environmental management, and public policy. It can be used in any situation where multiple options need to be evaluated based on multiple criteria.

## What are some examples of Multi-Criteria Analysis tools?

There are various tools available for conducting multi-criteria analysis such as Decision Matrix Analysis, Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and Simple Additive Weighting (SAW).

## What are some limitations of Multi-Criteria Analysis?

Some limitations of multi-criteria analysis include the possibility of biases, subjectivity, and difficulty in quantifying certain criteria. Additionally, it may be time-consuming to gather and process all relevant information.

## How can one get started with Multi-Criteria Analysis?

One can get started with multi-criteria analysis by first identifying the decision problem, defining the criteria used to evaluate each alternative, and assessing the relative importance of each criterion. Then, one can use a suitable tool to rank alternatives based on different criteria and aggregate these rankings to produce an overall score for each alternative.
