Taking environmental and sustainability issues adequately into account within the design process is mandatory but leads to additional complexity since even more engineering domains have to be involved in the process and since lifecycle information, like use of resources, has to be integrated and managed. Model-Based Systems-Engineering (MBSE) is an approach for managing the product’s complexity by using interconnected models. Yet, means for integrating information on environmental impacts are missing. Moreover, the knowledge integrated in the model, which reflects decision making processes, is not reused properly as a design experience for future products. This paper presents previous research about integrating environmental impacts and ecodesign in SysML to introduce a new Case-Based Reasoning (CBR) approach for adequately reusing previous MBSE experiences and results, such as environmental impacts. To do so, two databases are developed: one for the SysML models and one for storing own environmental impacts. Moreover, a specific retrieval process for selecting the relevant experiences is proposed. The paper ends with a discussion and a brief outlook about the research.
