工程项目设计方案优选的VA&CVM模型及其应用

针对工程项目设计方案优选中多属性、数据离散性、部分指标难以量化等特点，以某房地产商拟建住宅楼提出的5个设计方案为例，应用价值分析原理（VA）和变异系数法（CVM）的基本原理，建立项目优化设计的综合评价模型，并应用该模型对各种设计方案进行了综合评定，优选出最优设计方案。实例证明，该模型设计简便、结果客观可靠，为工程项目建设中设计方案的优选提供了一种科学、简便的决策手段。

VA&CVM Model for optimization of engineering project design scheme and its application

In view of characteristics of design schemes optimization in engineering such as multiple properties,discrete data and difficult quantification of some indicators,an comprehensive evaluation model for project design optimization is established,which uses the value analysis(VA) principles and the coefficient of variation(CVM) method,and takes 5 design schemes for a residential building as examples.These design schemes are evaluated comprehensively by the model and the optimal scheme is determined.It is proved that the model is simple,objective and reliable,which provides a scientific and simple tool for decision making of engineering project design optimization.
