Implementing AHP Approach to Select a Proper Method to Build High-Rise Building (case Study:Tehran)

Abstract

Tehran is one of the most densely populated cities in the world and one of the most important problems of it is the lack of suitable land for the building, so there is a strong need to build high-rise buildings. High-rise buildings desperately need to improve the integration, planning and control of construction quality, etc. This has leaded to the creation of innovative and modern techniques in the high-rise building industry that each of these methods has its own advantages and disadvantages, but despite the pressing need, a comprehensive research has not yet done on the appropriate way for high-rise buildings in Tehran. It is tried in this research, given the effective criteria on high-rise building, to select the best option, considering the methods that there is the building possibility in the current situation. In this paper, at first 15 most important effective criteria for decision making to select proper method of high-rise building in Tehran was identified through questionnaire. Then AHP methodology and Expert Choice software was used to choose the best industrial method for high-rise building in Tehran. In this survey the most appropriate method for high-rise building in Tehran was identified in the condition of applying all the identified criteria that they are respectively: tunnel formwork, concrete buildings (traditional), steel bolt and nut, steel buildings with welded joints, Reinforced concrete structures with continuous frame.

“…Moreover, this process is based on paired comparison. This comprehensive system demonstrates the compatibility and incompatibility of the decision which is a superior advantage of this technique in multi criteria decision-making (Mohaghegh et al , 2015; Kia and Adeli, 2014). Likewise, to integrate the layers of factors, overlay and fuzzy models were used (Araghi et al , 2011).…”

“…This study uses AHP as the primary research method. It provides objective mathematics to address the inevitable subjectivity and personal preferences of individuals or groups of decisions, empowering models with group decision-making capabilities [19]. Furthermore, it can construct a set of pairwise comparison matrices for each element at the upper level to compare elements in the lower level [20].…”
