摘　　要：以基于最大覆盖选址模型的供应链系统为对象,研究了边设施失效对其可靠性的影响。建立了以系统效率最大或最小化为目标的确定性边失效和随机性边失效两种情形下的优化模型,由此给出了解决这类可靠性分析问题的一般方法。实例求解结果表明模型合理,有一定推广和应用价值。Taking a supply chain system based on the maximum covering model as the study object, this paper analyses the impact of edge facility failures to the system’s reliability. Two optimal models in deterministic and stochastic edge failures cases are established. The objectives of these models are to maximize or minimize the system’s efficiency. There-fore, the general methods for solving such reliability analysis problems are given. The solution of an instance shows that the models are reasonable and have significance to popularize and utilize.
