Abstract: (2094 Views)
Background and aims: Continuous improvement in safety is one of the important goals of successful organizations. The traditional method for assessing safety performance is the statistical analysis of incident data, which is known as lagging indicators. The use of lagging indicators cannot be useful since the goal of establishing a safety management system is continuous improvement. The purpose of this study is to provide a leading indicator for assessing the safety performance of the organization.
Methods: The present research is a mixed method study with the approach of the human factors theory that includes the organization, environment and individual factors. In this study, a scale developed and validated for assessing the factors affecting the safety of the organization. The fuzzy hierarchical process (FAHP) method was used to the weighting of the constructions In order to demonstrate the effect of different structures of the proposed scales on the safety performance index.
Results: a scale was developed with 83 items after the interview process to examine the factors affecting safety performance. Based on the results of face validity 6 items were eliminated. The mean value of the instrument's validity index was 0.77. According to the results of the fuzzy hierarchical analysis, the organizational factor with the highest weight load of 0.503 was the highest and the environmental factor with a weight of 0.173 had the least effect on the score of the organization's safety performance index.
Conclusion: Analysis of the study data showed that the designed scale is an objective and simple tool for evaluating the factors affecting safety performance and can be useful as a future performance indicator for assessing the organization's safety performance.
Keywords: Safety performance, Leading indicator, Fuzzy hierarchy method.
