| With increasingly complex supply chain structure, supply chain in which the internal and external environment changes, and supply chain globalization, a large number of uncertain factors increased the uncertainty is increasingly affecting the survival of the enterprise and supply Chain running. Structural reliability in the supply chain management, supply chain reliability if the lower member companies convergence may result in poor, high operating costs, total profits decline, and even lead to the failure of supply chain collaboration and disintegration, and therefore need to strengthen Reliability of supply chain analysis and management structure.Based on the relevant literature, the reliability of supply chain structure, studies are mainly on the overall reliability of the supply chain modeling and analysis and evaluation of research, and membership structure of the reliability of the supply chain of small, how will members of the business Introduced into the supply chain reliability and structural design, reliability analysis has become an urgent need to solve the problem, only through the supply chain design and optimization, in order to better manage and avoid risks.This paper uses literature research, mathematical modeling, and fault tree analysis on the structure of the supply chain function and overall optimization of reliability analysis. First, the collection of data and theory based on the factors affecting the reliability of the supply chain to identify and summarize the whole supply chain and its function and reliability of enterprises are defined and simple estimation; Secondly, the basis of reliability estimates, was constructed using fault tree analysis reliability of supply chain optimization model. Finally, the core of Shaanxi Heavy Vehicle business empirical analysis of the automotive supply chain, combined with a practical example, the specific impact of each factor by the degree of importance, to identify weak links in the supply chain function of the structure, causing the attention to these areas, Reduce the probability of failure of the supply chain occurred. |
