A system dynamics model for strategic management of spareparts in closed-loop supply chains

摘要

The strategy to recover components from discarded electrical and electronic equipment toobtain spare parts is promising, especially during the final service phase. In that phase, theoriginal product is no longer produced and the sources of new parts are often limited.Controlling those closed-loop supply chains is challenging. Decision makers have to choosewhen to acquire discarded equipment, when to recover used parts, and when to produce newparts. We developed a generic system dynamics model that provides a test for variousproposed policies to control closed-loop supply chains with parts recovery and spare-partssupply.
