Furthermore, future research could improve the
simulation model and adapt the model to take into
consideration the number and location of
decentralised facilities and the corresponding
transport implications (i.e. transport time, cost and
CO
2
impact).
4 CONCLUSION
This paper presents a discrete-event simulation tool
that practitioners may use to model a future reverse
supply chain that does not exist and has limited
historical data. Managers and practitioners can use
the model proposed to measure the impact of changes
in processes, routes and volumes in terms of
throughput, capacity (number of batteries processes,
tonnes of material recycled, remanufactured batteries,
repurposed batteries) and sustainability impact of
changes (economic savings, CO
2
impact). The
insights of the model and the valuable metrics in
terms of capacity planning and economic and
environmental metrics were considered valuable by
the industry experts who participated in this study to
assess what-if scenarios and make informed RSC
design decisions.
