IASC - Optimal Economic Age Replacement Models For Non-Repairable Systems With Sudden But Non-Constant Failure Rate

WEBINAR RECORDING

SLIDES

Proper maintenance of non-repairable systems is essential for optimum utilisation of systems to prevent lost production runs, cost inefficiencies, defective output which leads to customer dissatisfaction and unavailability of the facility for future use. This work proposes new preventive replacement maintenance models with constant-interval preventive replacement time with associated cost of replacement maintenance. Improved results of economic values with respect to optimal replacement time at minimum cost were obtained for radio transmitter system with sudden but non-constant failure rate when compared to some existing models. Other parameters and maintenance probabilities of the system were also obtained including; reliability, hazard rate and availability to ascertain the operational condition of the system.
