TRUTH-VALUED FLOW INFERENCE AND ITS MATHEMATICAL THEORY
Truth valued flow inference (TVFI) theory treats fuzzy inferences as the processes of the truth values flowing among propositions, and focus intention to the analysis of structures of inference channels. In this paper we give a survey to a mathematical theory for TVFI, in which the basic concepts of channel lattice and background graph, the essential reason of reasoning, the formula of how to determine the confidence degree of channels, and the idea of how to combine knowledge from different sources such as experts' experience, statistical data and causality laws, …, those contents have been introduced.
