Portal frame systems are widely used as coverage system in industrial projects. Selecting the proper portal frame system for a certain project depends on many technical, financial and logistical factors such as estimated cost, construction duration, availability of materials, equipment and skilled labor, besides environmental factors such as recycling and durability. The aim of this research is to create a Decision Support System (DSS) to decide the optimal portal frame system considering all these factors. The proposed (DSS) depends on integrating the Value Engineering (VE) concept with the Analytical Hierarchy Process (AHP) technique to identify the optimum system. The considered systems in this research are conventional portal made of hot rolled section, pre-engineered built-up portal frame, trussed frames and portal Frame truss. The developed (DSS) was tuned for the current Egyptian market conditions in 2019 and successfully verified using four selected projects with different height to span ratio.

决策支持系统,以选择最佳的钢铁门架覆盖系统

门框系统被广泛用作工业项目中的覆盖系统。为某个项目选择合适的门框系统取决于许多技术,财务和后勤因素,例如估计成本,工期,材料,设备和熟练劳动力的可获得性,以及诸如回收和耐用性等环境因素。这项研究的目的是创建一个决策支持系统(DSS),以考虑所有这些因素来决定最佳的门户框架系统。提议的(DSS)依赖于将价值工程(VE)概念与层次分析法(AHP)技术相集成,以确定最佳系统。本研究中考虑的系统是由热轧型材制成的常规门架,预先设计的组合式门架,桁架和门架。
