Effort-reduced reliability assurance in product variant development considering prior knowledge

Due to the increasing demand for product individualization, the development of product variants is constantly growing. The product generation development (PGE) model can be used to describe the development of new products and their variants. With the development of new variants, renewed reliability tests must be carried out for reliability assurance. During development, only cost-intensive prototypes can be tested, making it impractical to test all product variants. Information from a previous variant cannot be simply transferred to new product variants, as even small differences can have a major impact on failure behavior. The aim of the research project is to develop a methodology for effort-reduced reliability assurance in variant development by systematically analyzing similarities on the basis of the PGE model. Based on identified similarities, a methodology for transferring reliability information to product variants is to be developed to significantly reduce the testing effort. By reusing and repurposing the reliability information, a significant reduction of effort for reliability validation shall be achieved.
