چکیده

Abstract Reducing the system failure rate of logistics service supply chain (LSSC) is the basic guarantee and supporting conditions of LSSC system operational stability. The paper, regarding the automobile logistics service supply chain system composed by logistics service integrators, logistics service providers and car manufacturer as the research object, sets up the fault tree model of the automobile logistics service supply chain system failure, and describes, by the triangular fuzzy number, the probability of basic event failure. Then based on the examples, the paper calculates the confidence interval of automobile logistics service supply chain failure, logistics integrators failure and logistics functions provider failure, and concludes the fuzzy importance sequence of basic event for the logistics service supply chain system failure. Finally, the paper analyzes the reasons for the logistics service supply chain system failure and proposes improvement measures.

Application of Fuzzy Fault Tree Analysis on Oil and Gas Offshore Pipelines

Fault Tree Analysis (FTA) as a Probabilistic Risk Assessment (PRA) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. To conduct a quantitative FTA, one needs a fault tree along with failure data of the Basic Events (BEs). Someti...

Overcoming the uncertainty in a research reactor LOCA in level-1 PSA; Fuzzy based fault-tree/event-tree analysis

Probabilistic safety assessment (PSA) which plays a crucial role in risk evaluation is a quantitative approach intended to demonstrate how a nuclear reactor meets the safety margins as part of the licensing process. Despite PSA merits, some shortcomings associated with the final results exist. Conventional PSA uses crisp values to represent the failure probabilities of basic events. This causes...

Fuzzy consequence modelling of hydrocarbon offshore pipeline

The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to deal with this kind of phenomena. The main purpose of this study is to construct an easy metho...
