The grey relational analysis method of the grey systems theory are combined with the fault tree analysis method of reliability theory, and introduced to the analysis and diagnosis of mine hoist overrelaxation accident. The various fault pattern occurrence possibilities in fault tree analysis of mine hoist overrelaxation accident are analyzed and judged by calculating importance degree of the bottom event structure of the fault tree as well as the calculating and sorting of the grey relational degree.Among 8 minimum cut sets of 6 bottom events ,”lake of the overrelaxation switch of the parking place” is most prone to overrelaxation accident ,”the driver’s negligence” is also prone to overrelaxation accident ,which provides theoretical basis for accurately preventing the fault occurrence. Calculation example shows the effectiveness and reliability of this method.

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.

In recent years, with the rapid development of petroleum, chemical and energy industry around the Yangtze River, the variety and quantity transportation of dangerous chemicals has also dramatically increased through Yangtze River. This paper applies fault tree analysis method of specific LPG to obtain problems existing in the Yangtze river water transportation safety management and according to these series of problem, it puts forward some relevant management measures, hoping to minimum the possibility and damage of potential risk accident so as to the risk control measures more scientific, strict and meticulous.
