Comparison of Economic Cost and Effectiveness Between Existing Salt Industry Maintenance Program, Reliability Maintenance Program and Age-Replacement Maintenance Program on Salt Crusher Machine

This study compared an existing salt crusher machine maintenance program to two other maintenance programs. Due to the limited technology of detection against damage, high content of salinity and conventional engine conditions so that it requires different maintenance program than the existing maintenance program. This study provides the statistical calculation and analysis of the lifetime data of each salt crusher machine component in order to find the best maintenance scheduling program. The lifetime data is calculated to predict the distribution of the failure so that the best replacement time can be determined by using age-replacement formula. The cost and the effectiveness of maintenance are then compared in order to find the best maintenance program among three maintenance programs.
