针对变电项目现行造价管理的不足,结合全寿命理论和方法,研发了变电站项目全寿命设计决策系统,提出了适合我国国情的变电项目工程分解结构和费用分解结构,阐述了数据库设计、费用单元估算、全寿命费用评价实现的理论和方法.该系统可以合理确定和有效控制工程造价.%The decision support system for substation project design based on theory of life cycle cost has been developed in connection with the inadequacy of existing substation project cost management. It puts forward a substation project breakdown structure and cost breakdown structure which satisfies China's national condi tions , and expounds the theory and methods for achieving database design, unit cost estimates and life cycle cost evaluation. The system can be used to reasonably identify and effectively control the project cost, besides, the system designed should make life-cycle cost technology applicable to a wide range of substation projects.
