Abstract

ABSTRACT: Early design decisions are central to many circular economy approaches and largely determine environmental impacts. Yet LCA practice is often fragmented and difficult to integrate into engineering development processes. This paper proposes an MBSE approach that represents and computes LCA-based (LCIA) impact indicators within SysML models using reusable, configurable model elements and automated import of characterization factors. A proof-of-concept implementation demonstrates technical feasibility, illustrates process integration, and discusses limitations and future work.
