生命周期投资估算方法及其在化工工程项目中的应用

Approach for Life Cycle Cost Estimation and Its Application in Chemical Industry

介绍了生命周期投资的概念及其估算方法 ,提出将生命周期投资分为静态投资和动态投资 ,并对静态投资费用 (包括初始购置费用和初始安装费用 )和动态投资费用 (包括设备操作费和维护维修费、生产损失费、报废设备或无用设备的处置费 )进行了详细的分析。用生命周期投资估算方法对一实例进行估算 ,验证了生命周期投资估算方法用于估算和优化工程项目投资 ,寻求最优投资方案是可行的 。

? The concept of life cycle cost and its estimation are introduced. The life cycle cost is composed of static costs including initial acquisition cost and initial installation cost,and dynamic costs including operating cost,maintenance cost,lost production cost,decommissioning cost.The analysis to the static cost and dynamic cost is presented.The practical results show the approach for life cycle cost estimation feasible. 〔
