Reliability evaluation method based on two-dimensional array system

The invention provides a reliability evaluation method based on a two-dimensional array system. The method comprises the following steps: step 1, determining a physical arrangement mode of the two-dimensional array system according to a to-be-evaluated system; step 2, numbering all elements in the two-dimensional array type system; step 3, determining a failure criterion of the system; step 4, determining the working probability of components a; step 5, calculating the probability that the number of system failure elements in the sub-region does not reach; step 6, calculating the risk of sub-region failure; and step 7, calculating a system reliability index value. According to the method, matrix operation is adopted and is a sparse matrix, so that the calculation speed is high, and a large-scale system can be evaluated; and the reliability of a system formed by heterogeneous components can be evaluated, and engineering requirements are met. 本发明提供一种基于二维阵列系统进行可靠度评估的方法，其包括以下步骤：步骤一，根据待评估系统确定二维阵列型系统的物理排列方式；步骤二，对二维
