How Can Machine Tool and Plant Manufacturers Increase the Trustability of the Needed Reliability Figures?

Large manufacturing companies demand reliability and availability warranties from their machine tool and plant suppliers. For these suppliers, however, the estimation of these figures is challenging. The challenges include sparse data availability due to short product life-cycles, low production volumes and high variance of different products, as well as the effect of different operating conditions on reliability. This presentation will show a practical methodology with which these companies can estimate increasingly trustworthy reliability figures. Furthermore, it will propose a method for assessing the trustability of the figures.
