Abstract
For incomplete information systems, based on the equivalent classification of domain objects, the definitions and properties of relation graph, relation matrix and class of limited tolerance relation are studied. The limited tolerance class can be calculated intuitively and clearly by using the relation graph or relation matrix of the limited tolerance relation. The granularity matrix of degree multi granularity rough set based on limited tolerance relation is proposed. The lower approximation of variable degree multi granularity rough set can be quickly calculated by using the granularity matrix.

A variable precision rough set model based on the granularity of tolerance relation
As one of core problems in rough set theory, normally, classification analysis requires that "all" rather than "most"elements in one class are similar to each other. Nevertheless, the situation is just opposite to that in many actual applications. This ...
