Tont, A Multilevel Approach of Reliability Optimization

Abstract:- Reliability optimization of complex systems is aligning in the larger framework of solving business and technical issues by adopting solution and decision-making under the simultaneous multi-objective conditions. The optimization is a key problem in the conceptual design, the implementation and realization in context of use of system. The feasible directions of reliability improvement may be achieved by reducing system complexity, increasing reliability of components, using structural redundancy or adequate maintenance strategies. The paper focuses on the opportunity of using continuous Markov chains, which allow modeling the behavior of complex systems under realistic time-dependent operational conditions, as an approach on managing and equipment stocks, a tool of reliability centered maintenance. The proposed simulation method is based on minimizing the stocking and failure costs of equipment under constraint of available acquisition and stocking sum. The case study, assessing two alternative situations of studied system, validates the effectiveness of method
