摘要
供应链系统是一个复杂的动态系统,许多影响因素的存在,使得供应链系统具有强烈的随机性,从而直接影响供应链系统的可靠性,我们通过分析供应链系统的状态之间的转移关系,引入增补变量法,用偏微分方程组建立了供应链系统的可靠性模型,并对该模型系统解的存在唯一性进行了讨论和证明.
Supply chain system is a complex dynamic system. Because of amount of impactive factors, supply chain system is strongly random. In this paper, we firstly build the reliability model for supply chain system. Then the existence of a nonnegative time-dependent solution is proved by using Co-semigroup theory.
