摘要
对完全模糊线性系统=,当为模糊方阵或模糊长方阵时进行了讨论.扩充了LR-模糊数的定义,讨论了完全模糊线性系统的模糊近似解和非负模糊近似解,并应用矩阵的广义逆阵A^-,讨论了广义完全模糊线性系统的模糊近似解和非负模糊近似解.最后给出了具体算例.
The fully fuzzy linear system （shown as FFLS） ^~A ×^~x =^~ b whose coefficient matrix is a fuzzy or square fuzzy matrix, was discussed. The definition of the LR fuzzy number was extended, and the fuzzy approximate solutions and non-negative fuzzy approximate solutions to the FFLS were discussed. Through the generalized inverse matrix A^-, the fuzzy approximate solutions and non-negative fuzzy approximate solutions of the generalized FFLS were investigated. Finally, a test example was given.
