Method and device for constructing change risk assessment knowledge base

Abstract

The invention provides a method and device for constructing a change risk assessment knowledge base, and belongs to the field of change management. The method comprises the steps: acquiring a change application form of a change instance, the change application form comprising change items, change names and risk description of the change instance, and the risk description comprising deviation, reasons and consequences; respectively carrying out similarity judgment on the change item, the change name and the risk description of the change instance and a preset change risk assessment knowledge base; and determining whether to add the change item, the change name and / or the risk description of the change instance to the preset change risk assessment knowledge base or not according to a judgment result. Therefore, the risk assessment is effectively assisted, the alteration risk can be effectively identified, the risk assessment work can be conveniently completed, and the comprehensive and systematic assessment is ensured.

Description

technical field [0001] The invention relates to the field of change management, in particular to a method and device for constructing a change risk assessment knowledge base. Background technique [0002] The high-risk characteristics of petrochemical enterprises make it easy to cause relatively large accident consequences and negative social impacts in the event of an accident, which will weaken the social image of the enterprise in the long run. Many major accidents can be traced back to the cause of change. Among the 1,633 accidents in the EMARS, CSB, FKD, and ARIA accident reporting systems, 149 accidents involved changes. Among them, the third place is that the change risk assessment is insufficient, so that the change risk cannot be effectively identified. The reasons for this include insufficient personnel ability to effectively identify the risks brought about by the change. The existing change risk assessment personnel are not capable enough, and there is no effect...

Problems solved by technology

Among them, the third place is that the change risk assessment is insufficient, so that the change risk cannot be effectively identified. The corrective reason includes the lack of personnel ability to effectively identify the risk brought by the change.

The existing change risk assessment personnel are not capable enough, and there is no effective knowledge base to assist in risk assessment to ensure a comprehensive and systematic assessment
