基于灰色摆动模型的水利工程价差预备费分析

Difference analysis of price based on Grey prediction

目前我国水利水电工程所采用的价差预备费计算方法是根据复利计算思想,采用固定不变的概算编制年综合物价指数进行计算的;由于该方法并没有考虑物价各年变化的差异性,使得价差预备费的计算存在较大的误差。以灰色理论为基础,建立了新的价差预备费计算公式,以提高预备费计算的准确性。

the ideas tendering. At present the method of reserve funds is adopted in construction project according to of the compounding, fixed years of composite price index was used to calculate Because this method does not consider the yearly differences of price, it made the gap between the calculation of reserve funds, and the results exist larger error. Based on the Grey Theory, a new formula of reserve funds was established, to Promote the accuracy of reserve
