Determining the probability of failure modes by fault tree analysis

The aim of the paper was to analyze the failure modes in the manufacturing part of the company in the production of products. To achieve this aim, we decided to use the FTA analytical methods - the fault tree method and the FMEA method. We analyzed the CNC milling machine HOLZHER 7120. We constructe...

Industrial Management The aim of the paper was to analyze the failure modes in the manufacturing part of the company in the production of products.

We used the FTA method to calculate the probability of occurrence of the basic events leading to the failure of the top event.

We used the FMEA method to find out the causes of failures resulting from the FTA method, the probability of their occurrence, their effect, and the probability of detecting the failures. We rated the failure probability factors, the impact of failure occurrence, and the probability of detection using a numerical scale from 1 to 10 with an assigned meaning for each level. By multiplying the ratings of these factors, we obtained the overall RPN. Based on the results of the FMEA method, we determined measure suggestions for factors with RPN values greater than 30.
