Remanufacturing Process of Defense Assets with Stochastic Yield

摘要

This study provides the analysis of the material planning strategies for six remanufacturing settings that are common to defense assets and to other technical equipment. These settings are classified according to two dimensions: the supplier's lead time to deliver replacement components (compared to the duration of the process), and the stage in the process that the recovery yield is identified (before disassembly, after disassembly, or during component repair). The production plans for the three settings with short supplier's lead time are solved optimally. The long supplier's lead time of the three other settings complicate the analysis, so the paper offers production plans that approximate the optimal policy in these cases.
