| Abstract: | Based on Copula function,The paper studies systems of reliability with comment components,then solves the problem about the reliabilities,the average life and the failure rate of systems,and investigates relation of the average life between dependence and independence with parallel components with the effect of orthant dependence,upper limits of parallel and series systems,moreover,analyses the limit of components and the dependence to the impact of the average life through examples. |
