Suitable life cycle properties and their associated designs were evaluated and determined, with respect to the expected, individual life cycle paths. The approach is applied to the design of a door panel for passenger cars. A meta model is developed to describe divergent life cycle paths of individual products and investigate, how to identify the possible, future life cycle paths in early stages of design and how to incorporate them in LCE. Thus, this paper addresses how such individual life cycle paths can be made accessible to product system designers in the context of LCE, to evaluate and determine valuable life cycle properties. The expected and realized value of certain life cycle properties might vary greatly within the same type of product. However, the life cycle paths of individual products from the same product type increasingly diverge, due to differing product usage, personalization and software or hardware updates. ![]() Life cycle engineering is concerned with designing such product properties in early stages of design. They are determined during development, but their impact-and thus value-only becomes apparent in later life cycle phases. Life cycle properties are becoming increasingly important for the success of a product. ![]()
