讨论对偶完全模糊线性系统(DFFLS)~M~x+~a=~N~x+b~(其中~M、~N是由LR模糊数组成的n×n型模糊方阵,~x~、a、b~是由LR模糊数组成的n维模糊向量)的模糊近似解,给出其模糊近似解的直接算法和Cramer规则算法,并通过具体算例验证两种算法的可行性.
The fuzzy approximate solution of the dual fully fuzzy linear system(DFFLS)~M~x+~a=~N~x+b~ was discussed, where ~M、~N and ~x、~a、b~ being n × n fuzzy square matrix and n-dimension fuzzy vector, composed of LR fuzzy number respectively. The direct method and the Cramer rule method for solving the dual fully fuzzy linear system were given. And a numerical example of the solution validated the feasibility of these two methods.
