The research of hierarchical risk element transmission theory base on fuzzy extended AHP

Hierarchical risk element transmission theory is one of the main aspects of the risk element transmission theory. The traditional AITP models are usually based on the precise data; however, the attributes of the actual indexes are usually uncertain when risk factors are considered. In order to solve the problem of multi-criterion objective decision upon uncertain indexes attributes when the risk factors are considered, this paper uses triangle fuzzy numbers to instead 1-9 of traditional AHP to decide the priorities of different attributes, and the hierarchical risk element trammission resolution model is constructed. Then the hierarchical analysis derivation is conducted based on every index considering risk element probability distribution, and further the probability distribution of the total objective evaluation score is calculated. which makes the evaluating scores providing more complete information to the decision makers.
