碩士 === 國立中央大學 === 機械工程學系 === 85 === With the progress of technology, complex and multi-function manufacturing devices have been one of the idiosyncrasy of industry. In this furious competition world, the reliability engineering has gotten more and more focus, because manufacturers had noted the important of stable and high-quality product. However, doing a reliability analysis in those complex devices is a difficult work. It depends the stable of produce device that whether production is successfully or not. Unfortunately, once a device work, there exists a rate of function degradation. A suitable maintenance is an important action on devices to avoid the unstable because function-decay. In this paper, we use fault-tree analysis (FTA) method, a good method for analyze a complex system, to find the reliability behave of Flexible manufacturing System (FMS). We will evaluate an FMS in the point view of reliability. Also, we use FTA to discuss the result after a repair apply to an element. The target of this paper, we try to find a maintenance policy of a system with three kinds of periodic and preventive maintenance work -- replacement, repair and clean-up/adjustment.
