摘要
基于一种特殊的单次冲击型负荷模型,对供应链系统受到冲击源N(t)为强度λ的poisson流冲击时的可靠性进行了研究.当冲击间隔小于常数δ时供应链失效,给出了供应链的可靠度函数及数字特征.研究表明可以通过预测该特殊冲击型负荷模型下供应链的期望寿命,做好应急物流保障.
According to a kind of special single impact load＇ model, the reliability of a single supply chain is studied when it is subjected to impact occurring randomly in time according to Poisson process with intensity 2. The supply chain fails when the interval of impact is smaller than a provided constant δ. The reliability functions and figure characteristics of the supply chain can be derived. And the research shows that we indemnify logistics in an emergency through forecasting the expected life-span of supply chain under this special impact load model.
