Abstract

Assessment of the state of health and working condition of equipment in the production and service industries is a necessary condition for effective maintenance. Therefore, this work models the failure times and other operational characteristics of television transmitter system with sudden but non-constant failure rate to enhance smooth operation of the system. The failure times was shown to follow lognormal distribution with mean;  and variance; . The Probability functions, hazard, reliability functions/indices, availability and maintainability factors were obtained to described the failure behaviour and ascertain the performance efficiency of the system. Also, a preventive replacement (PR) model for the system yielded an optimal replacement time of 189.112 hours at a minimum total cost of 178.134 naira per unit time. A combination of both estimates of the reliability indices and the PR model is recommended to provide complementary information for efficient maintenance operation of the TV transmitter and similar systems.
