Based on this,a general algorithm for realizing the membership transformation was realized for the synthesis evaluation of driver\'s road safety.

The principle of algorithm is to achieve space transform between gray image space and generalized fuzzy space by using linear generalized membership transform (LGMT) and its adverse transform.

The subject relationship between the AM500 shearer malfunction omen and reason is fuzzy,therefore,draw fuzzy mathematic method into shearer malfunction diagnosis,bring forward setting up the fuzzy membership grade method which is based on the history data and expert preferential ordinal number,found the fuzzy diagnostic model,carry out the fuzzy diagnosis on AM500 shearer malfunction in computer.

The membership grade targets of fuzzing mathematics are applied in selecting a first rate mining method from five methods on the mining conditions of gently dip middlings of Jianshan gold mine and the same mining method from abroad for reference .

A new evaluation approach known as the multiobjective synthetical membership grade deviation is discussed,and its application,this paper.

Approach of removing noises and outliers for SVM based on fuzzy membership;

Determination method of membership of Fuzzy SVM;

Fuzzy support vector machine algorithm with dual membership;

Based on gray relational theory,the concepts of relational dispersed degree and subordinate degree were introduced to improve grey identification method.

A comprehensive assessment model of water quality was set up based on subordinate degree and genetic neural network.

As regard to the standard for the environmental quality of the surface water, the subordinate degree function in the difference of the water quality and potential power parameters has been established in accordance with the fuzzy mathematics theory.
