Disassemblability evaluation method (DEM) for green product

Disassembly is a fundamental process needed for component reuse and material recycling in all assembled products. Disassembly activities take place in various recovery operations including remanufacturing, recycling, and disposal. Disassembly is often a labor intensive and costly process. Techniques...
