Project risk importance assessment method and system

Abstract

The invention discloses a project risk importance assessment method and system. The method comprises the following steps: 1) establishing a hierarchical structure influencing a final target; 2) for the evaluation information of each expert, obtaining a corresponding evaluation result; constructing a judgment matrix of each criterion layer in the hierarchical structure according to the evaluation information; calculating the relative weight of each element in the t criterion layer to each factor in the upper layer, and sorting to obtain a weight vector Wt; for each factor in the t criterion layer, calculating a relative importance weight sequence of the risk layer factors in the hierarchical structure relative to the k factor Ck of the criterion layer connected with the risklayer factors based on the overall universal risk probability and the characteristic attribute matrix of the project risk management; correspondingly multiplying the weight vector formed by the obtained weight sequence by the weight vector corresponding to each criterion layer to obtain an evaluation result of the expert; and according to each evaluation result obtained in the step 2), determininga risk factor which has the maximum influence on the project.

Description

technical field [0001] The invention proposes a project risk importance evaluation method and system, belonging to the technical field of computer software. Background technique [0002] Risk assessment is to use scientific methods and means from the perspective of risk management to systematically analyze the threats faced by information systems and their existing vulnerabilities. During the assessment process, different assessment indicators are set according to different industry requirements for risk assessment. Refer to Chinese patent ZL 201210249442.0, name "A multi-objective optimization method and system suitable for risk assessment", patent ZL 201510358980.7, name "risk assessment method for two-way interactive service operation mode between power grid and users", patent ZL 201210201461.6, name " Credit Rating System and Method Based on Matching Credit Rating and Default Loss Rate" and other documents. In the process of project risk management, it is generally nece...
