A New Bidirectional Approximate Reasoning Approach Based on Vague Set
基于Vague集的双向近似推理

In this paper we propose a new similarity measures in order to overcome some problems in 1], and propose the idea for similarity direction of vague sets by which to describe which one is more accurate between vague sets. At same time we propose a method to determine the similarity direction. Based on above,we present a new bidirectional approximate reasoning approach on vague set that fully uses the message accuracy of vague set. So this improves the accruacy and applicability of approximate reasoning. This provides a useful tool for approximate reasoning in intelligence system.
