The Design And Applicaton Of Fuzzy Decision-making Method

The decision is a common activity in people's life and work.Decision-making information is needed from personal development to political and diplomatic business planning and national military.Thus,decision-making is so closely related to our daily lives.However,in real life,a large number of decision-making is fuzzy,multi-level,multi-objective and non-structural.Fuzzy decision-making is the mathematical theory and method of decision-making in the fuzzy environment.This kind of problem is characterized with general system,and the relation between the system is very complex;there are not accurate assignment variables,these variables are fuzzy factors;involving some subjective factors,making the relationship between the subsystems and variables not clear,so sorting and fuzzy evaluation method to carry out processing must be used.Fuzzy comprehensive evaluation and decision making is one of the methods of fuzzy decision making.It is a systematic analysis method using fuzzy mathematics to analyze and evaluate the "fuzziness".It is a combination of qualitative and quantitative methods based on fuzzy reasoning.Due to the unique advantages of this method in dealing with all kinds of difficulties to use accurate mathematical methods to describe the performance,in recent years,it is widely used in many disciplines such as artificial intelligence,control,decision,special system,medical science,construction,agriculture,meteorology,information,economy and education and other fields.In addition,the students' evaluation of classroom teaching is a multi-factor evaluation process,which is a more complex evaluation system.Using the fuzzy comprehensive evaluation model is reasonable and feasible,so based on the theory of fuzzy comprehensive decision model,this paper realizes the teaching evaluation of students by using the model.First of all,a set of factors and evaluation is set up.Then determine the weight and the membership function of the fuzzy relationship matrix through the investigation and statistics.After that the final results of the students' evaluation of teaching is made through the selection algorithm,using the maximum membership principle.Finally,the model is implemented and applied in the computer.
