摘　　要：业务影响分析是业务连续性计划中较为关键的一步,其最终目标是对企业中业务的重要性进行排序。文中的目的是提出一种企业在进行灾难恢复时,各个业务过程之间恢复优先顺序的排序算法。该算法在设计时基于RTO进行排序,并考虑了业务之间的相互依赖关系对恢复顺序的影响。通过实验显示了该算法的合理性:使用该算法可以更好地实施业务影响分析,缩短分析时间,从而提高整个业务连续性实施过程的效率。Business impact analysis is a critical step in implementing the business continuity plan, and the final goal is to sort the businesses of the enterprise. The article proposes an algorithm for recovering priority sequence of the businesses when the enterprise carries on the disaster recovery. The algorithm is based on RTO and considers the influence of the interdependency among the businesses. The experiment proves the rationality of this algorithm. By using the algorithm, the business impact analysis could be better implemented, thus to shorten the analysis time and raise the efficiency of the whole implementation of the business continuity.

关 键 词：业务连续性 业务影响分析 恢复时间目标
