Abstract
The correct management of skilled human resources is always considered as one of the basic requirements in the construction industry, and the productivity of this people is one of the key factor on the performance of construction projects, and not paying attention to this issue causes irreparable damages to the projects. In spite of this fact, the research conducted on the risk-generating factors affecting the productivity of human resources in projects, with shortcomings such as the lack of comprehensiveness in the process of identifying risks, not paying attention to the interactions between risks, not considering the risk-generating factors and their impact on resource productivity Human faces. In this research, while examining two high-rise construction projects, the risks and interactions between them were identified and analyzed using the two methods of Fuzzy Demetal-Dynamic System. First, ten key factors affecting the productivity of human resources as the origin of risk were identified and validated through the literature and experts' opinions; In the following, interactions between risks were evaluated and analyzed using a questionnaire method, using the fuzzy Demetal method and causal loops. Then, by considering the interactions between risks and how they affect the productivity of human resources, a dynamic model was presented, and finally, the effect of each risk on productivity was simulated by considering the interactions. Based on the obtained results, the risks of executive interference on the site, rework, communication and coordination and falling from height have the greatest impact on reducing the productivity rate of human resources, respectively.
