全生命周期费用结构体系是工程项目全生命周期费用管理的重要方法之一。在建立面向元素或构成部位的水利枢纽工程系统分解结构的基础上,提出了由二维费用结构矩阵和成本映射模型构成的水利枢纽工程全生命周期费用结构体系。应用此方法,可以在不同的层次组织汇总项目费用信息,对项目费用进行层次分析和控制,可以在项目不同阶段对任意层次的费用控制单元的费用要素进行管理,实现全生命周期费用的优化管理。
The whole life-cycle cost structure system is one of the important methods of project life-cycle cost management. On the basis of establishing the system decomposition structure of water conservancy project oriented to elements or parts, the cost structure system of full life cycle of water control project constructed by two-dimensional cost structure matrix and cost mapping model is proposed. This method can be used to organize the project cost information at different levels and analyze and control the project costs hierarchically. The cost elements of the cost control units at any level can be managed at different stages of the project to achieve the optimization management of the entire life cycle costs .
