Today, I would like to talk to you about what Topsis is. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can gain something according to this article.

Definition:

TOPSIS method is a commonly used comprehensive evaluation method, which can make full use of the information of the original data, and its results can accurately reflect the gap between the evaluation schemes.

Limitations of Analytic hierarchy process:

Problems and solutions:

So the final scoring formula is:

The index is positive, and the positive matrix is obtained:

Standardize the positive matrix and eliminate the dimensions:

Calculate the score and normalize it:

Steps:

The unified index type is very large index.

Four common indicators:

Very large (benefit type) index

Very small (cost type) index

Intermediate indicator (close to a certain value)

Interval index (falling in a certain range)

Standardize the value of the index and eliminate different index dimensions.

Different indicators may have different weights, and the weight is calculated by Analytic hierarchy process (AHP). After obtaining the weight of the index, the weight coefficient is added in the standardized processing.

The unnormalized score of each evaluation object is calculated according to the scoring formula and the normalization matrix (n objects, m indicators).

4. Normalization of score for each object
