针对现有风险分析方法无法较好地描述风险在系统运行过程中的分布情况,提出了面向试验过程的风险分析方法.该方法能够对系统进行全面的描述,并可以给出系统的风险事件分布.在风险识别阶段使用风险分布图和风险事件分析表,使分析人员更容易掌握系统风险分布的全局和细节,最大限度避免风险事件遗漏;在风险管理阶段使用风险分布图,将风险事件与试验过程或作业环节相联系,可以使管理人员和作业人员直观了解系统中风险存在的位置和形式,更有利于风险的控制.该方法使风险分析更接近于试验任务过程实际,更容易为工程技术人员所掌握.%A new method of system risk analysis which is faced to test process is proposed according to risk analysis methods existed not describe the distribution of risk in operating process of system.With the new method,system and the risk event distribution can be described comprehensively.All risk events can be found and no one lost in the risk distinguish used risk distribution diagram and risk event analysis table.Manager and operator can understand the location and forms of risk in the system in the risk management stage used risk distribution diagram which can relate risk event and operate link.And this method is in favor of risk control.This method makes risk analysis even closer to practical project,and so it is easier to be understood by engineers.
