Original Article


Reliability significantly influences system’s performance and its life cycle costs. Poor reliability would greatly increase life cycle costs of the systems, and reliability based design must be carried out if the system is to achieve its desired performance. Additionally, optimal level of repair is determined to reduce life cycle costs of the fleet systems. Traditionally for such systems, reliability design and level of repair analysis is done sequentially. It is hypothesized in this research that such decisions have interaction effects and hence simultaneous optimization of reliability design and level of repair would improve the life cycle performance of the system. Present paper aims to develop a decision framework for simultaneous selection of reliability design and level of repairs for fleet systems.
