基于IFAHP的BIM管线碰撞优化模型

针对BIM管线碰撞技术尚不能根据碰撞位置给出管线的优化方案问题,利用直觉模糊层次分析法(IFAHP)建立了一种BIM管线碰撞优化模型。首先,依据建筑管线施工规范,从施工成本、施工难度、施工安全性和施工美观度四个方面建立了管线碰撞评价指标体系;其次,根据碰撞点位置状况,依据IFAHP构造出不同的直觉模糊判断矩阵,建立相应的直觉模糊决策模型,进而给出不同管线碰撞点的管线优化方案。最后,通过实例验证了该BIM管线碰撞优化模型的有效性和可行性。

Pipeline Collision Optimization BIM Model Based on IFAHP

Pipeline collision technology of BIM can effectively simulate the collision problem of HVAC pipes,electrical pipelines,water supply and drainage pipelines in complex construction projects. However,this technique cannot give an optimized solution according to the location of the pipeline collision currently. Motivated by this,BIM pipeline collision optimization model is established based on the intuitionistic fuzzy analytic hierarchy process (IFAHP). Firstly,a pipeline collision evaluation index system is given by construction costs,construction difficulty,construction safety,and construction aesthetics in accordance with construction pipeline construction specifications. Secondly,different intuitionistic fuzzy judgment matrixes are given according to IFAHP and the position of the collision point,corresponding intuitionistic fuzzy decision optimization models are established,and then the pipeline optimization solution for different pipeline collision points is given. Finally,the effectiveness and feasibility of the BIM pipeline collision optimization model are verified by an example.
