Study on Information System Disaster Recovery Planning

摘要

摘要: 灾难发生时，需要有量化的、精确的方法从多个子灾难恢复计划中选择最优集合实现灾难恢复。该文采用最优化理论提出一个灾难恢复计划数学模型。模型表示系统中不同应用、设施、资源、子灾难恢复计划、预算等以及它们之间的关系，对资源进行分类，解决不同子灾难恢复计划之间的冲突。模型具有较少的主观参数，以实现客观评价灾难恢复计划，易于对灾难恢复计划进行精确、量化的分析。论文给出了模型的实施步骤与模型分析，实验验证了模型的正确性。

Abstract: When disaster happens, it is necessary use quantitive and accurate method to select the best set from many sub disaster recovery plans to control the disaster recovery activities. This paper presents a practicable mathematical model using optimization theory. The model contains some parameters that stand for different applications, facilities, resources, sub plans, budget, etc. The model classifies resources and solves the conflicts among various sub disaster recovery plans. With less subjective parameter, the model can evaluate DRP more impersonally. The model possesses less parameter and can be easily implemented to analyze DRP accurately and quantitatively. The implementation and the analysis of the model are presented. Test also verifies the correctness of this model.
