中文摘要：

可靠性是评价应急物流体的重要指标之一。根据应急物流体构件的复杂多变性，提出与传统系统可靠性不同的计算方法，并将仿真预测引入应急物流体可靠性指标计算，为评价多态、多结构的应急物流体总体可靠性提供基本算法。

英文摘要：

Reliability is the most important index in evaluating ELS3. On the basis of complexity and levity of ELS3 , new algorithm, which is different from traditional system reliability, is brought forward. And simulation to calculate reliability about ELS3 is introduced. Thus a basic algorithm to evaluate collectivity reliability about a muhi-state, muhi-structure ELS^3 is offered.
