摘要

近年来,伊朗的公路建设项目面临延期、终止或推迟数年的问题。虽然对发达国家和发展中国家的延迟问题进行了广泛的研究,但在伊朗进行的研究很少。由于延误问题在伊朗的重要性和缺乏足够的研究,本研究旨在首先,发现公路建设项目延误的最重要原因;对关键因素进行排序和排名,以便为公路建设项目主管部门突出它们。编制了一份经核实的调查表,分发给参与伊朗建设项目的专家。对收集到的有效数据进行探索性因子分析,揭示变量的内在结构,减少变量的数量。此外,层次分析法(AHP)作为一种流行的决策工具,对重要因素进行了优先级排序。研究结果表明,“设计”和“承包商”是伊朗公路建设项目延误的最关键标准。此外,施工材料采购不当、制造材料延误和施工过程中发生事故是造成延误的最重要因素。这项研究首先有助于确定伊朗作为一个发展中国家建设项目延误的最重要原因并确定其优先顺序,因为缺乏关于这一主题的充分研究。此外,它还强调了伊朗建筑项目的任何有关各方延误的原因,以消除延误。关键词:组件,格式,样式,样式,插入(关键词)

An Analytical Hierarchy Process of Delay causes in Highway Construction Projects in Iran
Recently, the highway construction projects in Iran have been confronted with delay, terminated, or postponed for several years. Although widespread studies have been investigated, regarding to delay issue in developed and developing countries, however, only few studies addressed in Iran. Due to the importance of delay issue and lack of sufficient studies regarding to this topic in Iran, this study aimed to first, discover the most significant causes of delay in highway construction projects, second; prioritize, and rank the critical factors, in order to highlight them for highway construction projects authorities. A verified questionnaire prepared and distributed among the experts in the construction projects of Iran. The valid collected data analyzed by Exploratory Factor Analysis (EFA) to uncover the underlying structure of variables and reduce the number of them. Moreover, Analytical Hierarchy Process (AHP), as one of the prevalent decisions making tools, applied to prioritize and rank the significant factors. The study results revealed that the “Design” and “Contractor” were manifested as the most critical criteria regarding to delay in highway construction projects in Iran. Besides, poor procurement of construction materials, delay in manufacturing materials and accidents during construction were discovered as the most significant factors causing delay. This study contributed first to identify and prioritize the most significant causes of delay in construction projects in Iran, as a developing country, because of lack of sufficient studies regarding to this topic. Additionally it highlights the causes of delay for any involving parties in Iran construction projects in order to eliminate delay. Keywords—component, formatting, style, styling, insert (key words)
