Then it puts forward the method of interval-number fuzzy comprehensive evaluation,designs the evaluating quota system,and applies them into practice in the School of Medicine.

In this paper,an attribute value with a fuzzy interval number was given in order to investigate the effects of "human being","automobile"and"road"on the traffic security of a high way,an evaluation system is set up,and a judging matrix is formed by AHP.

N-L Formula of Fuzzy valued Functions on the Fuzzy Number Interval [  ,];

Based on the GIS and RS technologies,the paper developed a method of spatial fuzzy comprehensive assessment about bird habitat suitability in the nature reserve,and researched the spatial expression of the subordinative degree and the confirmation of weight vectors,and extended the field of fuzzy mathematics at assessment of environment.

In addition,the fuzzy fitness function it takes can evaluate the fitness of individual more objectively.

Firstly, the paper introduces the conception of good point distance and advances a fuzzy penalty function, then sets up a fuzzy fitness function, so it lets the fitness of individual has more rationality and objectivity.
