Project risk decomposition identification method based on safe operation basic function requirement

Abstract

The invention relates to the field of project risk decomposition and identification, and discloses a project risk decomposition identification method based on a safe operation basic function requirement, wherein the method settles a problem of high difficulty in performing accurate risk identification and logical relation carding. The method comprises the steps of performing system decomposition on a complicated project system from a high grade to a low grade so that mutual independence and completeness of a lower sub-system and an upper parent system are realized; finding out a to-be-satisfied function requirement of each sub-system based on the safe operation basic function requirement; analyzing possible events which affect realization of the function requirement; performing causal reasoning on each possible event, and finding out a reasoning event of the possible event; and analyzing the result of each reasoning event. The project risk decomposition identification method is suitable for complicated systematical projects such as water power engineering and civil engineering. The project risk decomposition identification method has an important application prospect in risk identification and analysis aspects of the complicated systematical projects and can realize a Bayesian risk network for constructing a complicated systematical project.

Description

technical field [0001] The invention relates to the field of engineering risk decomposition and identification, in particular to an engineering risk decomposition and identification method based on the basic functional requirements of safe operation. Background technique [0002] Engineering risk refers to the uncertainty that may lead to engineering losses, that is, the possibility that the occurrence of a potential event will bring adverse effects to the engineering. The identification of engineering risks is an important basis for risk assessment and prevention and control. [0003] Common engineering risk identification methods mainly include brainstorming method, Delphi method, consulting method, checklist method, historical data method, system decomposition method, WBS method, cause-and-effect diagram method, SWOT analysis method, etc.; Tree analysis method, event tree analysis method, analytic hierarchy process, decision tree method, Monte Carlo method, data envelopm...
