Fuzzy error matrix based on fuzzy error logic is used to express current status u, expectant status u1 and transformation matrix T. It is u,u1, and T that are used to build fuzzy error matrix equation T(u)=u1. It allows us to find a method that bad status “u” change to good status “u1” by solving equation. The purpose of solving fuzzy error matrix equation is to get a decision support about how to...
In this paper, the concepts of omegathetas-closed sets and omegathetas-open sets in Lomega-spaces are introduced, and the omegathetas-convergence theory of filters in an Lomega-space is established. By means of the omegathetas-convergence theory, some important characterizations with respective to the omegathetas-closed sets, omegaT2 separation and (omega1,omega2) theta-continuous mappings are obtained.
