基于潜语义模型的电网信息作业实施方案风险评估方法

Risk Assessment Method of Power Grid IT Job Implementation Scheme Based on Latent Semantic Model

电网企业级信息系统每次进行增量升级、消缺等作业时会严格按照实施方案进行,实施方案步骤不严谨、对风险的疏忽会带来巨大的安全隐患。针对现阶段人为对实施方案进行评估存在的管控力度不够、风险细节易疏漏等问题,提出基于潜语义模型的变更作业实施方案风险分析方法。试验证明了本文方法可有效发现电网信息作业实施过程中潜在的风险,可在电网实际信息作业中推广应用。

The power grid enterprise-level information system will be carried out in strict accordance with the implementation plan when performing incremental upgrades and eliminating shortages.The inadequate steps of the implementation program and the negligence of risk can bring great security risks.At present,the artificial evaluation of the implementation plan has insufficient control,risk details being easy to be omitted and other issues.In view of these problems,this paper proposes a risk analysis method for changing job implementation plan based on the latent semantic model.Experiments show that this method can effectively detect the potential risks in the implementation of power grid information operation,and can be popularized and applied in the actual IT job of power gird.
