摘要
本文讨论[O,1]格上max-*合成模糊关系方程A·x-6的同解问题,部分回答了J.Drewniak与Z.Matusiewicz于2010年提出的开问题(Propertiesofmax-*fuzzyrelationalequations.Soft Computing,2010,14(10):1037~1041)。首先给出了与方程A·x=b同解的方程的系数矩阵的一些性质,然后给出了A·x=b的同解方程的系数矩阵所构成的偏序集成为格的充分条件。
This paper investigates the properties of fuzzy relational equations with max-* composition which have the same solutions to A o x=b in [0,1] and partly answers the open problem raised by J. Drewniak and Z. Matusiewicz in 2010 (Properties of max- * fuzzy relational equations. Soft Computing, 2010, 14(10):1037~1041). First, it gives some properties of solution invariant equations of A o x=b, and then obtains the sufficient condition that the poser of coefficient matrices of solution invariant equations to A o x=b forms a lattice.
