The parameters c and ? of the soil shear strength are calculated with the random-fuzzy analysis method in which the fuzziness of soil sample parameters is considered.

Targeting with the uncertainty factors of suppliers selection problem, the essay depicts the problems by using fuzzy random parameter, and establishes the model of fuzzy random expected-value.

Based on the fuzzy random theories and fuzzy random event,in this paper the method of structural fuzzy reliability analysis is developed when the fuzziness and randomness of generalized stress and generalized strength are considered.

The existence and uniqueness of solution of the fuzzy random Volterra integral equations on the condition of mean square integral is proved.

The dynamic response of a truss to fuzzy-random changes in design parameters under stationary random excitation is studied in this paper.

In this paper the effect of structural reliability as a result of human error is analyzed and the model and practical method of calculating fuzzy-random reliability considering the effect of human error are proposed.

The random-fuzzy method was used for calculating fractal dimension of grain size distribution by considering the randomness and the irregularity.

In this paper,the future unit capital investment yield is characterized as a random-fuzzy variable,which according to the trait of corporate can be divided as follows: high yield,medium yield and low yield.
