对于价值工程中对象选择方法的比较研究

价值工程中关于改进对象的选择始终是一个基本问题,如何选取准则是关键。现在就20世纪中期至今的7种主流方法一一进行比较分析,从区域几何特征(包括区域关于标准直线的渐进性以及非对称性)、解析表达式在价值工程上的经济意义、待定常数的易得性、应用中的便利性四个方面进行比较,并给出初步结论。

To Study on Comparing of Selection Methods for the Objects in Valuve Engineering

The selection of objects for improvement is always a basic problem,and how to choose a proper criteria is the key piont in value engineering(VE).So,it calls for comparative research on seven primary selection methods proposed and developed from mid-20th century to today.The research will include four aspects:the geometric characteristics of the accepted region(asymptotic approximation and unsymmetry about the standardized line),the analytical expression's economic implications in VE,the accessibility of und...
