by using fuzzy random variable theory and fuzzy set theory, the concept and its calculation method of fuzzy random characteristic quantity of safety grade are put forward.
a model of general uncertain programming with fuzzy random variable parameters is put forward in this paper;
提出了一类具有模糊随机变量参数的普遍型不确定性数学规划模型;
this paper introduces two models of fuzzy random linear programming which have fuzzy random variable coefficients and pseudorandom decision variables by discussing a practical engineering problem.
