应用模糊数学原理快速估算工程造价的研究

Research of applying fuzzy mathematical theory in quick evaluating project cost

为满足建筑工程投资估算的需求,从分析建筑工程造价构成出发,得出影响其造价的主要因素。基于模糊数学的方法,估算拟建工程的造价,具体通过模糊关系系数计算贴近度,使已建工程与欲估工程的相似度定量化,再采用择近原则,用贴近度大的几个工程估算欲估工程造价,结果表明该计算方法是可行的。

In order to satisfy requirements of building project investment evaluation, it commences on analysis of building project cost component, gets main coefficients of having influences on cost, based on method of the fuzzy mathematics, evaluates cost of building project, concretely according to the fuzzy relationship coefficient calculates closeness degree, makes ration similar degree between built project and pre-evaluating project. Using project press close degree pre-evaluates project cost, result proves that this calculation method is feasible.
