基于全生命周期集成的大型工程项目风险控制模型

Risk Control Model for Large-scale Project Based on Lifecycle Synthesis

基于工程项目全生命周期管理的角度和综合集成方法,应用动态规划方法建立大型工程项目的风险控制模型,对大型工程项目实行全生命周期的动态集成风险管理。并以某大型工程施工期间的风险管理为例来验证模型的可行性和有效性,提出大型工程项目的工程主体应当遵照ALARP的风险可接受准则来实施风险控制措施,将风险降低到合理和实用的范围:只有当降低风险的成本和所获得的效益之比是在合理的可接受的情况下,才应执行这一风险控制措施。

This paper introduces a lifecycle risk control model for large-scale project based on lifecycle management and meta-synthesis.A large-scale construction project is taken as an example to examine the feasibility and practicability of the proposed model.In accordance with the principle of ALARP（as low as reasonable practicable）,risk management for large-scale construction project should reduce to a reasonable and practical extent,and implement the risk control action only when the ration of cost action paid and benefits received is in a reasonable case.
