基于项目全生命周期成本和效益的工程设计方案经济比选

Economic Comparison and Selection of Engineering Design Schemes Based on Project Life Cycle Costs and Benefits

对当前工程设计方案经济比选中存在的问题进行了梳理,简要介绍了工程设计方案经济比选的基本原则和方法,以实际案例为基础进行了分析,结果表明:工程设计方案经济比选应考虑项目全生命周期的成本和效益,进行动态分析,才能得出正确的方案经济比选结论。

Sorts out existing problems in comparison and selection of current engineering design schemes,and briefly introduces the basic principles and methods in comparison and selection of engineering design schemes.Also,analysis is carrited out based on actual cases.The result shows that,to get the correct economic comparison and selection conclusions,the costs and benefits of the whole project life cycle should be considered in comparison and selection of engineering design schemes and dynamic analysis should be carried out.
