## Why we use TOPSIS method?

Table of Contents

Some of the advantages of TOPSIS methods are: simplicity, rationality, comprehensibility, good computational efficiency and ability to measure the relative performance for each alternative in a simple mathematical form.

**Who introduced TOPSIS method?**

Yoon and Hwang

The TOPSIS method was first developed in 1981 by Yoon and Hwang [3]. Its basic concept is that the chosen alternative should have the shortest distance from the ideal solution and the farthest from the negative-ideal solution (Figure 1) [3,4].

**What is TOPSIS method PDF?**

TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is one of the numerical. methods of the multi-criteria decision making. This is a broadly applicable method with a simple mathematical. model. Furthermore, relying on computer support, it is very suitable practical method.

### What is TOPSIS in MCDM?

Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) came in the 1980s as a multi-criteria-based decision-making method. TOPSIS chooses the alternative of shortest the Euclidean distance from the ideal solution and greatest distance from the negative ideal solution.

**Where is TOPSIS used?**

TOPSIS technique has been commonly used to solve decision-making problems. This technique is based on the comparison between all the alternatives included in the problem.

**What is the meaning of Vikor?**

Multicriteria Optimization and Compromise Solution

The name VIKOR appeared in 1990 from Serbian: VIseKriterijumska Optimizacija I Kompromisno Resenje, that means: Multicriteria Optimization and Compromise Solution, with pronunciation: vikor. The real applications were presented in 1998. The paper in 2004 contributed to the international recognition of the VIKOR method.

#### When should the AHP be used compared with the TOPSIS?

Regarding your question AHP and TOPSIS are methods based on different concepts. AHP is based on weighted aggregation and its criteria and alternatives weights are obtained by pair-wise comparison and DM preferences. TOPSIS is based on distance. That is, it is assumed that there is an ideal and non-ideal solution.

**What is Dematel method?**

Abstract. Decision making trial and evaluation laboratory (DEMATEL) is considered as an effective method for the identification of cause-effect chain components of a complex system. It deals with evaluating interdependent relationships among factors and finding the critical ones through a visual structural model.

**What is saw method?**

Simple Additive Weighting (SAW) is one of the methods used to solve multi-attribute decision problems. The usefulness of the basic concept of the SAW method is to find the number of weighted performance ratings for each alternative on all attributes [10].

## What is multi-criteria decision making methods?

4.3. Multi-criteria decision making (MCDM) also referred to as multiple criteria decision analysis (MCDA), is a research area that involves the analysis of various available choices in a situation or research area which spans daily life, social sciences, engineering, medicine, and many other areas.

**How do you use the AHP method?**

How to Use the Analytical Hierarchy Process (AHP)

- Step 1: Define Alternatives.
- Step 2: Define the Problem and Criteria.
- Step 3: Establish Priority amongst Criteria Using Pairwise Comparison.
- Step 4: Check Consistency.
- Step 5: Get the Relative Weights.
