（武漢水利電力大學建工系 430072）[提要] 屋蓋網架結構選型在一定程度上屬決策行為，因而不可避免地存在人為主觀因素的影響。傳統(tǒng)的做法是選擇幾種不同型式的網架和屋面荷載等進行結構分析，然后通過技術經濟的比較來選定方案。這種方法，需要花費較長的時間和較多的人力，且很難對每一種網架型式都進行比較，也很難廣泛聽取專家的意見。有鑒于此，我們進行了采用AHP法優(yōu)選廠房屋蓋網架結構方案的研究，結果表明：該法不僅可以克服傳統(tǒng)方法的一些缺點，而且可以反映出各方案的優(yōu)先次序以及各方案的排序權值，具有省時、省力、適用的特點。
[關鍵詞] 網架選型 AHP法Traditionally, we determine the space truss form by analysing the several forms of space truss and their technical and ecnomic indexes. Usually, the process costs much time and we need do a lot of work. But by AHP(Analytic Hierachy Process), selecting form of space truss can be convenient by consulting specialists and simple mathematical processing and results in not only the optimum space truss form but also the weight values of space truss forms. Therefore, it's a vey useful means for us to do such kinds of works in the feasible studies.
Keywords: space truss form; roofs; AHP; optimum seeking method
