By using entropy weighting and entropy weighting evaluation of estimate, this paper structures a risk evaluation model for the distribution of bank resources with m evaluation objects and n evaluation indexes, and illustrates the practicability of this model with some actual examples.

So,this paper analyzes some evaluation systems of patents and benefits from the perspective of economics,and consequently suggests some factors which must be considered for the evaluation of patent value.

To solve this problem,an advanced algorithm based on weighting-coefficient cumulative estimation is put forward,and the weighting coefficient is the result of variable precision rough set algorithm.
