Modeling of Material Selection for Product Improvement Considering Quality, Innovation, and Life Cycle Assessment

Abstract. The product development process can be considered from a "cradle to grave" perspective. Making rational material choices that drive efficiency in production, use, and end-of-life seems crucial. Therefore, the aim of this article was to propose a modeling framework to support the materials selection process in product improvement, taking into account aspects of quality, innovation, and environmental impact throughout the life cycle. The model operates in six main stages, expanded with selected techniques to support their implementation. It is based on the identification of product usability, innovation, and environmental impact criteria within the life cycle. Material prototypes are analyzed to assess the importance of these criteria and their fulfillment based on the adopted assumptions. The entire process is presented in a flowchart illustrating a systematic approach. The materials selection model can be applied to materials selection for any product, for example, in the electrical machinery industry. It can be used by designers, engineers, and managers in the early stages of product development, as well as during product improvement for sustainability.
