Human Factor Interrelationships to Improve Worker Reliability: Implementation of MCDM in the Agri-Food Sector

Performance Shaping Factors (PSFs) are contextual, individual, and cognitive factors used in Human Reliability Analysis (HRA) to quantify the worker contribution errors when performing a generic task. Although empirical evidence demonstrates existence of PSF interrelationships, majority HRA methods assume their independence. As consequence, resulting Error Probability (HEP) might be over- or underestimated. To deal with this issue, only few qualitative guidelines statistical-based approaches have been proposed so far. While former not well structured, latter require high computational effort proper number input data. Therefore, present paper provides an alternative approach PSFs interaction issue facilitate identification most influential human on which take corrective actions. purpose, Multi Criteria Decision Making (MCDM) may represent effortless, easily replicable framework. Owing ability interdependence decision factors, DEMATEL ANP hence considered afterwards compared, highlighting strengths weaknesses.
