目的--伊朗社会保障组织2012年发布的统计报告显示，在所有行业中，建筑业与与工作有关的事故数量最多。此外，由于这一部门拥有大量人力，确定导致此类事故发生的因素至关重要。本文件旨在讨论这些问题。设计/方法/方法--此外，由于这一部门拥有大量的人力，确定导致此类事故发生的因素至关重要。在本研究中，首先确定了这些因素，然后选择了其中最重要的管理因素。随后，使用故障树分析(FTA)方法和OR与AND条目进行了管理因素的原因识别。发现-由于很难确定该行业发生事件的概率，并且由于灰数(其精确值未知且代表不确定信息的数字)与人的表情有很强的关系，除了对中间事件的发生概率进行排序外，还使用灰数作为输入条目来评估主要不良事件的发生概率。原创性/价值-研究结果表明，使用灰数的FTA是一种有用和有效的风险评估工具。
Purpose - The statistical report published by the Iranian Social Security Organization in 2012 showed that, of all industries, the construction industry is associated with the highest number of work-related accidents. Furthermore, as this sector contains a large human workforce, identification of the factors contributing to the occurrence of such accidents is vital. The paper aims to discuss these issues.Design/methodology/approach - Furthermore, as this sector contains a large human workforce, identification of the factors contributing to the occurrence of such accidents is vital. In the present study, such factors were initially identified, after which the most important of these, managerial factors, were selected. Subsequently, the identification of the causes of the managerial factors was carried out with the use of the fault tree analysis (FTA) method and application of OR and AND entries.Findings - Since it is difficult to determine the probability of occurrence of events in this industry with certainty, and because gray numbers (numbers of which the exact value is unknown, and which represent uncertain information) have a strong relationship with human expressions, the probability of occurrence of the main undesired events was also evaluated using the gray numbers as input entries, in addition to ranking the probability of occurrence of intermediate events. \Originality/value - The findings revealed that FTA using gray numbers is a useful and effective tool in risk assessment.
