Exploring some fuzzy integration methods and applying them to self-assessment work

Abstract

 

In daily life, we often solve the problem of choosing an option, making a decision that we think is best based on certain pre-determined criteria. The assessment is based on each criterion, can be in numbers (i.e. points) or in languages ​​("good", "excellent”...). However, in the case of verbal assessment, the problem becomes more complicated because it is difficult for determination. To overcome such limitations, the fuzzy set theory approach can be a more flexible solution to many problems. In this article, the author uses a fuzzy integrated method that uses the fuzzy set theory in self-assessment to produce acceptable results in converting from quantitative to qualitative values.

Keywords: Fuzzy set theory, integrated fuzzy, Qualitative evaluation.
