Reliability-based Optimization of Maintenance Scheduling of Mechanical Components with the Method of Accelerated Tests

To have effective production planning and control, it is necessary to calculate the reliability and maintenance of a production system as a whole. Therefore, with today’s highly reliable components, we are often unable to obtain a reasonable amount of test data under normal use condition. For this reason, accelerated tests method is the reasonable procedure to be applied. It is used to determine the reliability of a product in a short period of time by accelerating the use environment. Application of the method of accelerated tests can save cost that we used to pay for overcoming the dilemma of not being able to estimate failure rates by testing directly at use conditions. In this paper, we propose a practical method for system reliability analysis. Among the existing methods for system reliability analysis, reliability graph theory is particularly attractive due to its intuitiveness, which is an extension of the conventional reliability graph. A function library was developed and designed to calculate the reliability-maintainability and availability of parallel series complex systems, whose functional description is translated into a block diagram that combines in series and parallel components studied. An Extensive analytical modeling study has been performed also to verify the effectiveness of the proposed technique.
