Weakly linear systems of fuzzy relation inequalities and equations have
recently emerged from research in the theory of fuzzy automata. From the
general aspect of the theory of fuzzy relation equations and inequalities
homogeneous and heterogeneousweakly linear systems have been discussed in two
recent papers. Here we give a brief overview of the main results from these
two papers, as well as from a series of papers on applications of weakly
linear systems in the state reduction of fuzzy automata, the study of
simulation, bisimulation and equivalence of fuzzy automata, and in the social
network analysis. Especially, we present algorithms for computing the
greatest solutions to weakly linear systems.
Keywords: fuzzy relations, fuzzy relational systems, fuzzy relation inequalities, fuzzy relation equations, matrix inequalities, residuals of fuzzy relations, fuzzy equivalence relations, complete residuated lattices, post-fixed points
