On the basis of comparing the traditional empty wagon allocation model,the paper establishes a multi-objective empty wagon allocation fuzzy planning model which takes the satisfaction of consignors as the maximum goal and gives out an example.

Fuzzy mathematics was applied for establishment of fuzzy planning model, based on which, the method for choosing highway construction organization design scheme was obtained and achieved satisfactory result in real case.

Study of synthetical quality evaluation for yarn performance based on fuzzy division;

The membership function is constructed,and the optimal fuzzy division could be gained by iterative algorithm,then the samples are classified on the principle of the maximum membership grade,and finally the classification ration.

The fuzzy indirect identifying method was used to get proper three fuzzy divisions and then establish three fuzzy normal states vectors to coordinate the three fuzzy divisions.
