Optimizing the Risk of Building Environments Using Multi-Criteria Decision Making

Construction industry is known as one of the most dangerous industries in the field of air pollution which causes damage to the environment and endangers human health. Therefore, in order to reduce and control risks by construction industry, planning is necessary. The method used to discuss the risks is MCDM. After interview with 15 experts, the weights of scales were discussed. Some criteria are used for risks; in this study, the insights and suggestions used include risk comprehension, risk evaluation, safety risk, and safety performance. Weight of four main scales was performed by Super Decision software. Paired comparison of the main scales was performed in terms of 9 hourly quantitative scale, the same as AHP process. According to the research, more weight was given to risk comprehension, and less weight was devoted to safety insight. The results show that in order to control risks, risk comprehension has high priority in building environments.
