Abstract: Present study determines maintainability of mechanical systems of electric cable shovels utilized in Garp Linyitleri Isletmesi (GLI). Independent and identically distributed data are identified using tests for trends and serial correlation in order to represent the repair time data probabilistically. Three probability distributions are tried as possible candidates to fit Time To Repair (TTR) data. Finally, maintainability for different time periods and Mean Time To Repair (MTTR) values of shovels have been estimated on the basis of fitted distribution models.
