Fuzzy FMEA in Risk Assessment of Human-Factor in Production Process

Risk is inherent in any activity, including manufacturing. The engineers face various factors of risk while managing the production processes, such as accidents, breakdowns, defective parts and much more. Despite the increasing automation of production processes, many activities are still performed with human assistance. The management of human resources, including the scheduling of operators, is - like any other activity - associated with the risk of the emergence of sudden needs for change, usually related to random causes. Risk assessment is a complex task, requiring a holistic approach and the ability to analyze the situation in terms of both past events and the future. In the article, the aim was to verify the possibility of applying the fuzzy logic in this kind of risk assessment. To achieve this, the combination of classic risk assessment method FMEA and the fuzzy sets rules was used, which is called the fuzzy FMEA. It is the combination of two aspects which is getting more and more popular in literature. The research was performed based on data collected in industry.
