The Mathematical Model Of Subsidization Problem For Students From Economically Disadvantaged Families Based On Rough Set

Along with the national financial aid system for higher school to make major adjustments,various scholarships in lines,coverage and greater changes have taken place in evaluation method,etc. State grants selection was influenced by many factors,these factors it is unable to determine quantitatively. Currently,on aid for poor students have a lot of evaluation methods both at home and abroad,such as fuzzy comprehensive evaluation,AHP method and grey system clustering evaluation etc, some research has been very well. This article from the perspective of rough set,to set up a scientific subsidy scheme is easy to solve,to review assessment for poor students.First of all,this article simply introduces the problems of poor students subsidy and relevant state departments to make policy,and second,to introduce the theoretical foundation of the model:that is rough set theory,the Israeli toilet articles using rough set theory to solve problems discussed in this article:Again,an analysis of the problem how to establish a subsidies for poor mathematical model,the whole framework of the model building:Information matrix model is established in this paper,symbols,and then determined are illustrated,then the attribute reduction method based on rough set was studied,and lists the three kinds of commonly used methods,and puts forward the improved reduction algorithm;And then studied the weight vector; Finally,mathematic al simulation is studied by using revelant data,and the effectiveness of the advantages and disadvatages and model analysis.
