Fuzzy Fault Tree Analysis

In reliability field, the probabilities of basic events are often treated as exact values in conventional fault tree analysis. However, for many practical systems, because the concept of events may be ambiguous, the factors affecting the occurrence of events are complex and changeable, so it is difficult to obtain accurate values of the occurrence probability of events. Fuzzy sets can well deal with these situations. Thus this paper will develop a novel fault tree analysis method in the assumption of the values of probability of basic events expressed with triangular intuitionistic fuzzy numbers. First, a new ranking function of triangular intuitionistic numbers is established, which can reflect the behavior factors of the decision maker. Then a novel fault tree analysis method is put forward on the basis of operational laws and the proposed ranking function of triangular intuitionistic numbers. Finally, an example of weapon system “automatic gun” is employed to show that the proposed fault tree analysis method is feasible and effective.

Cutter suction dredgers (CSD) play a major part in the field of dredging engineering in harbors, fairways, and land reclamation. CSD can continuously mine and transport the slop with good quality while CSD can tackle many types of soil. However, even a component failure, which is connected with parts and components of CSD, can result in no working. Thus, it affects the production capacity and efficiency of dredgers seriously. It is necessary to analyze the failure probability of CSD. The method of Fault Tree Analysis (FTA) is applied to analyze the failure probability of CSD. The method uses logical reasoning and builds a fault tree model by analyzing the relationship between the basic, intermediate and top events. Based on fault tree model of a variety of events " and " " or " relationship, we can obtain minimal cut sets of that cause the event to failure. Then, get the basic probability of the event. Finally, we can calculate the probability of the top events. Under experiments, the FTA method can accurately calculate the failure probability of CSD, and deduce in reverse order the key events that cause the top event. The study on the key events can reduce the failure probability of CSD, enhance its reliability and safety, and improve the efficiency and productivity indirectly. It will also lay a foundation for product configuration optimization.
