The periodical renewal of spare parts in a manufacturing system is optimized by a novel approach using the well-known Weibull distribution. In essence, this is achieved by the use of a geometrical stepping in the description of the reliability to the points of renewal, hence, the spare parts required in the system to achieve the reliability target are then determined.

In this paper the possibilities of a qualitative and systematic procedure for the selection of the most developable concept in early design stages and the transfer of the gained information into a failure mode and effects analysis are shown. Further, the possibility of deriving reasonable lifetime distributions from the FMEA assessment values for the description of the system behaviour is demonstrated. With this integrative qualitative approach new products can be accompanied with a procedure, which passes on all its information without any losses, over the complete product design cycle.
