Reliability of a Transport Node based on Fuzzy Fault Tree Analysis

Abstract

In this work to be introduced a fuzzy fault tree real time algorithm to identify reliability of highly autonomous driving (HAD) redundant system of a traffic node. The fuzzyfication of the fault tree procedure was realized by expressing the basic events with a membership function. Logical gates had to be generalized based on incoming fuzzy events. Node dynamics were discretized in the form of a Laplace graph. The edges of the graph as fuzzy base events and the nodes of the graph as logical gates determine the reliability of the node.
