Abstract: (1023 Views)
Background and Objective: Increasing the efficiency and productivity of employees, along with reducing workplace accidents and incidents, are important goals that are always facing top managers of organizations. In this regard, examining the mental workload of employees is one of the issues whose results are important in advancing the goals of managers. The purpose of the research conducted is to present an integrated approach to examine the safety culture indicators in employees with regard to the effective components in the level of mental workload related to them.
Methodology: Considering the important effects that the work environment and the type of employee activity have on the level of employee safety culture, and also considering the workload, importance, and accuracy required in visual terminals of process industries, one of the workstations of Shazand Refinery in Arak has been considered as a case study. In this study, after identifying the mental workload components and determining the safety culture indicators, the opinions of experts who are supervisors and managers of the workstations in question were collected, and after determining the weights and prioritization using performance-importance analysis, using the Yager model, which is a fuzzy multi-attribute decision-making tool, the mental workload components were ranked based on the safety culture indicators.
Findings: Based on the research results, the components of "Employee Effort" and "Boring" obtained the highest and lowest ranks, respectively, and the indicators of "Leadership" and "Physical Structure of Culture" have the highest importance and the lowest performance, respectively, based on weight values. The results indicate that, considering the role of the leadership indicator in safety culture and considering high importance and low performance, supervisors of video terminals should focus on appropriate measures and pay attention to observing and implementing the relevant elements and sub-indices.
Conclusion: High performance and low importance in relation to the "physical structure of culture" indicate a waste of resources in this regard, and implementing programs appropriate to explaining the importance of this indicator for employees in solving this problem is important. On the other hand, focusing on the component of "employee effort", "eliminating the monotony of employee tasks" will play a prominent role in reducing accidents and adverse events caused by high mental workload and will increase efficiency and productivity.
Keywords: Safety culture, mental workload, performance-importance analysis, fuzzy multi-criteria decision making.
