The reliability on the basis of fuzzy design criterion is always bigger than neglecting fuzzy character,therefore the designed machine parts have even smaller size,lighter weight,and can much closer to engineering objective reality.

Research on Portfolio Selection with Probability Criterion and Fuzzy Criterion;

This paper first provides a brief introduction to the economic, probability and fuzzy criterion models in multistage decision processes,especially in inventory process and reservoir operation.

By combining model structure analysis based on singular value decomposition and fuzzy statistical information criteria, an optimal fuzzy cluster in the input space can be realized, and an optimal fuzzy inference system is attained.
