文章从工程风险源的角度进行风险的识别,选用适宜的方法辨识出工程风险因素,并列入风险清单。再从风险清单中选出主要的风险因素加以讨论。在风险分析阶段,采用层次分析法来确定各重要风险因子之间的关系,再结合信息墒理论建立的风险评价数学模型,用综合权重因子来评估风险大小,从而采取有针对性的措施进行风险控制和防范,使资源充分利用,风险成本降低,效益最大化。
The article identifies the risks from the perspective of engineering risk sources, selects appropriate methods to identify the engineering risk factors and lists them in the risk list. Then select the main risk factors from the risk list to discuss. In the stage of risk analysis, AHP is used to determine the relationship between the various risk factors. Combined with the mathematical model of risk assessment established by the theory of information entropy, a comprehensive weighting factor is used to evaluate the risk so as to take appropriate measures to carry out the risk Control and prevention, make full use of resources, reduce risk costs and maximize benefits.
