Water reservoirs are considered very important storage facilities for the condition of peak demand in the agriculture industry. The construction process of a water reservoir may be accompanied by multiple risks. This study is aimed at identifying the emerging risks resulting from variability in different functions and at prioritizing them based on the analytical hierarchy process (AHP) method. In fact, the potential variability (emerging risks), possible dependencies/couplings, and the barriers used for damping this variability were assessed using Functional Resonance Analysis Method (FRAM). The AHP method was then applied to prioritize the various functions. The results of FRAM modeling indicated that there was the possibility of a high variability in five functions. In this context, the AHP findings showed that “initial studies on the construction of the pool” with the weight of 0.310 and “excavation” with the weight of 0.308 were the most important functions in this study. In addition, the results of this study demonstrated that AHP may be a desired alternative for the identification of performance variability and the aggregation of variability.
Behavior, practice and how to carry out safe tasks by workers and industrial personnel who exposure to injuries and incidents, Depending on their understanding of the real risks in the workplace. The empirical definition of risk is expressed by calculating the probability of an incident and the magnitude of the consequences of an incident. Employee perceptions of occupational risks have a significant impact on their safety behavior in the workplace. Therefore, research on risk perception is an issue that has attracted many researchers' attention. This descriptive-analytical study was carried out in the winter of 2017 on workers of 10 technical workshops of one of the steel companies of Khuzestan province. Risk perception of workers was assessed using risk perception questionnaire with Cronbach's alpha 0.73. One-way ANOVA, One Sample T-Test and Post Hoc test were used to analyze the data. All perceived risk scores for people were at acceptable levels. The category of individuals in the marital status had the highest score and the experience of the people was the lowest score. Among demographics specification, only education is associated with an average risk perception score. The present study shows that none of the individuals' personal characteristics have a direct and positive impact on risk perception. In order to increase the level of risk perception of workers, planning and developing continuous training programs should be used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
