摘要

From the perspective of the process of distribution service,a copula based method is proposed to analyze the reliability of supply chains.The suppliers in the supply chain systems are not independent from each other and the dependency relation may be either linear correlation or nonlinear correlation.Copula is a popular tool for modeling the dependence structure.It contains the information about the dependency structure of a vector of random variables and can capture nonlinear dependence.In the paper we construct a model of k-out-of-n : G system to study supply chains.An evaluation method is proposed and the reliability indexes of distribution service are obtained.
