Our
research team conducts research in reverse production systems that contribute
to sustainability. Our research has resulted in new metrics and
analytical models to make strategic, tactical, and operational decisions for
reverse production systems. In the area of unsold product returns, we
defined tactical thresholds and developed new returns policies. We
developed a disposition algorithm for an operation with hundreds of daily
disposition decisions for customer returns. Once products are destined
for demanufacturing, the recycler must make strategic
production planning decisions. We developed a mixed integer programming
model to address simultaneously the acceptance, processing, and reprocessing
decisions for demanufacturing over multiple
periods. Next, the operator must schedule returned products for demanufacturing within a planning period. We defined
new metrics and developed new scheduling rules for demanufacturing
operations. An open problem in demanufacturing is the
recycling of plastics. We are currently engaged in multidisciplinary
research to improve the sustainability of the plastics supply cycle.
