Multi-factor data analysis based on rough set theory

When analyze the relation according to raw and/or random data, sometimes the method used now is not sufficient. Rough set theory has powerful ability to analyze the raw data . Based on the rough set theory, the support degree is introduced to act as measurement of relation between factors and objects. And the method to calculate support degree is introduced. Concept of intersection degree is set forth to measure the degree of several factors intersecting. At the same time, the arithmetic to compute intersection degree is set forth either. At last, feasibility of the method is proved by using it to analyze relationship between factors and performance of agriculture transportation vehicle.
