Mathematical Formulations for Asynchronous Parallel Disassembly Planning of End-of-Life Products

open access: yesMathematics, 2022
Disassembly is one of the most time-consuming and labor-intensive activities during the value recovery of end-of-life (EOL) products. The completion time (makespan) of disassembling EOL products is highly associated with the allocation of operators ...
