Assessment of the state health and working condition equipment in production service industries is a necessary for effective maintenance. Therefore, this work models failure times other operational characteristics television transmitter system with sudden but non-constant rate to enhance smooth operation system. The was shown follow lognormal distribution mean;

This paper deals with the modeling of a preventive maintenance strategy applied to a single-unit system subject to random failures. According to this policy, the system is subjected to imperfect periodic preventive maintenance restoring it to ‘as good as new’ with probability p and leaving it at state ‘as bad as old’ with probability q. Imperfect repairs are performed following failures occurri...
