fact, that there is no known implementation of a DLT for LCSA, there is also no data
basis for an assessment. Questions to be answered in this context are: Can LCSA
be applied to an underlying DLT system? Which specific characteristics need to be
taken into account? As a DLT is not solely a hardware neither a software product,
different requirements might arise. If a DLT is defined as a CPS, the LCSA of a CPS
can be used for guidance (Gürdür and Gradin 2017). Other orientations could be
LCSA of Product Service Systems (PSS) (Peruzzini and Germani 2013), if a DLT is
understood as a system of a physical product and accompanying services.
Future research steps should focus on the elaboration of the DLT concept as
well as the sustainability assessment of DLT implementations. In particular, the
applicable data structure and information content as part of the DLT for LCSA needs
to be defined. Furthermore, existing solutions for integrated and automated decision
support should be examined against the adaptability for LCSA. Ultimately, these
findings will contribute to the enhancement of the LCSA execution as well as to the
design of a support system to enable an environmentally and socially sound design
of products and services.
