Assessment of Risk in a Production System with the Use of the FMEA Analysis and Linguistic Variables

The paper describes a method for analysing and assessing the risk in production systems. A process of ore transportation process with the use of a belt conveyor was used as an example. Ishikawa diagram was used to identify the risk factors in the cause and effect analysis. In order to determine the extent of the impact of individual risk factors on the selected area of the production system, the FMEA analysis was used. When determining the values of the parameters needed for calculating the Risk Priority Number (RPN), defuzzified values of appropriate linguistic variables were used. The effect of the work is a reduction of the risk level in the analysed production system as well as the information about risk factors obtained on the basis of verbal communications from production workers.
