RESEARCHING OF THE CONFORMANCE RATING FOR LOCOMOTIVE REPAIR PRODUCTION
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 173, Issue 7
Abstract
The determination of the conformance rating of locomotive repair production is associated with the formalization of expert statements obtained during its survey. In the article the structure of the compliance indicator of locomotive repair production is analyzed, which is defined as the triple additive convolution of a number of criteria. Herewith it is taken into account: the rate of influence of nonconformities on the technological process of repair, the significance of technological repair processes, the significance of components of repair production and the significance of failures of locomotive units. Analysis of data of survey of locomotive repair productions shows that the total number of identified nonconformities lies in the range of 20-30. Herewith the most negative influence will have nonconformities, which are characterized by the maximum values of the criteria. In the article the critical values of the criteria for the conformance rating are defined, that is, those that can be a prerequisite for severe consequences if the repaired locomotive fails in exploitation. It is determined that the critical range of the weight of only nonconformity of production lies in the range of 0.012-0.063. And the acceptable values of the conformance rating of locomotive repair productions are 0.988 - 1.
