摘要:
 随着大型网络系统复杂性的不断提升，能否在规定任务时间内降低执行元件失效性从而提高系统执行可靠性变得格外重要。备用元件概念的引入大大缓解了此类矛盾。由于备用元件在等待替代过程中会出现失效现象，因此对网络中备用元件的要求也随之提高。在对备用元件进行选择分类时，混合备用的思想被用在了可靠性评估之中。从提高样本评估的准确率着手，提出一种启动备用元件的混合排序策略，并将它应用到预期任务成本评估之中。实验结果表明，在大多数情况下该策略均能取得预期的效果，能够显著降低备用元件失效的概率，保障网络系统中的任务能够顺利执行。
Abstract:
 With the rising complexity of a large network system,it becomes extremely important to improve the system reliability for im-plementation by reducing the failure of the implementation of the components within the mandated time. The concept of hybrid standby has greatly eased the contradiction. Fully considering the failure of standby elements in the process of the waiting for an alternative,the re-quirements of the standby elements of the network are increased. The idea of hybrid standby is applied to assess the reliability when as-signed the standby elements selection. In order to improve the accuracy of the sample assessment,a hybrid order strategy is presented to start standby elements and applied to the expected task cost assessment. The experiments show that in most cases the strategy can achieve the expected results which can reduce the probability of the failure of standby elements significantly,enduring network system for imple-mentation successfully.
