Quantifying human error probability (HEP) in maintenance is key to preventing accidents. This study uses MICMAC and system dynamics to model influencing factors and predict human error for better decision-making.
Area of Science:
- Industrial Engineering
- Occupational Safety and Health
- Risk Management
Background:
- Human error is a major cause of industrial accidents and operational disruptions, particularly in maintenance.
- Quantifying human error probability (HEP) and understanding influencing factors are crucial for mitigating risks.
- Performance Shaping Factors (PSFs) dynamically impact human error, necessitating predictive modeling.
Purpose of the Study:
- To determine and simulate HEP in cement factory maintenance tasks using PSFs.
- To analyze the interdependencies and impacts of factors influencing human error, occupational accidents, and costs.
- To forecast human error behavior over time and support managerial decision-making.
Main Methods:
- Cross-impact matrix multiplication applied to classification (MICMAC) analysis to assess factor relationships and impacts.
- System Dynamics (SD) modeling to forecast system behavior and simulate various scenarios.
- Integration of MICMAC analysis with SD for optimized human error prediction.
Main Results:
- MICMAC analysis identified and classified the dependencies and impacts of factors on HEP, accidents, and costs.
- The integrated MICMAC-SD model provides a framework for forecasting human error dynamics.
- Multiple scenarios were generated to illustrate potential outcomes based on HEP variations.
Conclusions:
- Understanding and quantifying HEP, considering dynamic PSFs, is essential for effective risk management in maintenance.
- The MICMAC-SD approach offers a robust method for predicting and managing human error.
- Informed managerial decisions based on HEP forecasting can improve safety and reduce operational disruptions.
