Fuzzy mathematics method is a mathematical tool to deal with uncertain problems. Its appearance solves the problem that traditional mathematical methods can't deal with fuzziness, uncertainty or ambiguity. Fuzzy mathematics method was first put forward by Japanese scholar Kenji Ishiguro in 1965, and then it was widely used and developed.

Fuzzy mathematics method is a mathematical theory and method based on fuzzy concept, which allows us to make decisions and reasoning in uncertain environment. The core idea of fuzzy mathematics method is to transform uncertain problems into mathematical problems and solve them through a series of mathematical operations.

Operation steps of fuzzy mathematics method

The operation steps of fuzzy mathematics method can be divided into the following steps:

1. Determine the problem: First, make clear the problem to be solved and determine the nature and characteristics of the problem.

2. Determine variables: According to the characteristics of the problem, determine the variables that need to be considered.

3. Determine the membership function: for each variable, it is necessary to determine its membership function, that is, map the variable to a membership degree to describe the fuzzy degree of the variable.

4. Determine the operation rules: according to the characteristics of the problem, determine the operation rules, including fuzzy logic operation and fuzzy relation operation.

5. Fuzzy calculation: according to the operation rules, fuzzy calculation is carried out on variables to obtain fuzzy results.
