Improvement of failure mode and effects analysis method for unauthorized gas tapping

The article presents the results of developing FMEA method on an example of illegal gas-tapping. The method was improved by means of classifying subjective factors and objective preconditions, which influence the estimates of the rate of occurrence, detection probability and significance of consequences in risk analysis. In addition, we used Quality Function Deployment to assess the influence of the factors and preconditions. The results presented in the article can be applicable in other areas with a corresponding change in the classifier, dependences and expert evaluation results. The paper is of interest for specialists applying FMEA in practice, as well as for postgraduate students and product quality scientists.
