利用Dubois和Prade所定义的LR模糊数及其近似算法,讨论了完全模糊线性系统A x=b(其中A是由LR模糊数组成的模糊矩阵,x,b是由LR模糊数组成的模糊向量)两种特殊情形下的模糊近似解,即齐次完全模糊线性系统HFFIS(2.4)和模糊线性系统FLS(2.5)的模糊近似解。
LR fuzzy numbers and approximation arithmetic operator defined by Dubois and Prade are used to finding some fuzzy approximate solution x which satisfies two special type of fully fuzzy linear systems A x = b, where A and b are a fuzzy matrix and a fuzzy vector consisting of LR fuzzy numbers respectively. Namely, it was the fuzzy approximate solution of homogeneous fully fuzzy linear systems HFFLS and fuzzy linear systems FLS.
