基于灰色关联分析的工程造价控制

从影响工程造价的土地费用、图纸设计及管理、施工图预算价、工期、工程变更费用和工料机信息价等6个因素出发,根据灰色关联分析理论计算出各因素与工程造价的关联度,得到各因素对工程造价灰色关联度的排序。研究表明:施工图预算价对工程造价的影响最大,管理者要注重施工图预算的编制策略和技巧,科学适度地控制此因素,这样可以避免发生"三超"现象,以较少的投入获得较多的效益。

Construction Cost Control Based on Grey Correlation Analysis

6 factors such as land costs,the costs of drawings’ design and management,the budgetary price of construction drawings,limiting time for a project,the costs of project change,the market price of labor material and machinery which affect the construction costs control are taken into consideration.According to grey correlation analysis theory,the grey relational grade of each factor and construction costs are calculated,and then the order of grey correlation degree of construction costs of all factors are also obtained.The research shows that the budgetary price of construction drawings is the greatest influential factor for construction costs.So managers should pay attention to the strategies and skills when they draw up the budgetary price of construction drawings,and then scientifically and reasonably control the factor,thus the "San Chao" phenomenon can be avoided,which means a relatively small input gains relatively more benefits.
