RELIABILITY ANALYSIS OF INTERNAL TRANSPORT SYSTEM FOR PRODUCTION OF PETROLEUM EXTRACTION EQUIPMENT

Dependability is an area that has been developing for decades and has been gaining more and more importance also in logistics. One of the main indicators of dependability is reliability, i.e. the probability that the item or system can perform a required function under given conditions for a given time interval. The paper presents reliability analysis of the internal transport system of the enterprise manufacturing equipment among others for petroleum extraction. On the basis of the operating data set the mean operating time between failures of transport system components and their dependence on the year of production will be presented. The reliability structure of the system will be defined and reliability index of the system for specific time will be evaluated in regard to the reliability block diagram. The components reliability importance will be determined and the reliability allocation for certain assumption will be performed. On the basis of that analysis some suggestions of changes in machinery will be made.
