In the paper, the proposition of application of two methodologies: the predictive scheduling and Total Productive Maintenance – TPM to increase efficiency of a production system is presented. To assess wastes due to unplanned events in the machine’s work the Overall Equipment Effectiveness (OEE) indicator is applied. Any failure of a bottle neck decreases value of the OEE. In this paper, the problem of predicting a time of the bottle neck failure is considered. In the paper, models of a production system and failures are presented. For the bottle neck various reliability characteristics are computed: the probability that, beginning with moment t₀ , the first failure occurs after given time t, probability that in the interval [f ,g], there occurs at least one failure, failure intensity function, Mean Time To Failure (MTTF) and Mean Time of Repair (MTTR). Having the MTTF and MTTR of the bottle neck, a robust schedule is generated. At the time of predicted failure, preventive actions and technical survey of the machine are scheduled. In the second paper a numerical example is given.
