风险是影响施工项目目标实现可能发生的事件.项目风险因素可分为技术风险和非技术风险两大类.风险事件是一种潜在的损失或收益.但在施工项目实施期间,大部分事件都是灾难性的.它的影响是不确定的.风险管理是识别和度量项目风险,规划并决策风险处理方案.检查控制决策执行效果的过程.其中,决策风险处理方案乃风险管理之核心内容.项目风险管理的目标是使工程造价、工期、质量、安全得以控制.按照决策相关条件的可控程度,决策可划分为常规决策和非常规决策.常规决策是指相关条件可控,决策结果预先可以计算的决策.非常规决策是指相关条件不可控,决策问题中的因素不确定,是具有概率变化的.无论决策选定哪一种方案,都要承担一定风险的决策.风险管理决策大多属于非常规决策.其风险的大小可用风险量来表示:
Risk is the event that may affect the achievement of the construction project goals. The project risk factors can be divided into two categories: technical risk and non-technical risk. The risk event is a potential loss or benefit. But during the implementation of the construction project, most of the events are It is catastrophic. Its impact is uncertain. Risk management is the process of identifying and measuring project risks, planning and deciding risk management solutions, and examining the process of controlling the effectiveness of decision-making. Among them, decision-making risk management solutions are the core of risk management. The goal of project risk management is to control project cost, schedule, quality and safety. According to the controllability of decision-making related conditions, decision-making can be divided into routine decision-making and unconventional decision-making. Routine decision-making refers to controllable conditions and decision results Decisions that can be calculated. Unconventional decisions are those where the relevant conditions are not controllable, the factors in the decision problem are uncertain, and they are probabilistic. No matter which scheme is chosen for a decision, they must bear certain risk decisions. Most risk management decisions are made. Belong to unconventional decisions. The size of the risk can be represented by the amount of risk:
