One aspect of product development which focuses on the recovery of resources at the end of the product lifecycle is Design for Disassembly (DFD). Disassembly evaluation chart methodology (DECM) is one of the various methods in DFD which can be used to evaluate the disassemblability of a product by using a spreadsheet-like chart with the respect to the disassembly difficultness for each task of the disassembly operation. The goal of DECM is to make products easier to disassemble. The evaluation result such as disassembly efficiency, disassembly time and disassembly cost estimation are calculated and evaluated to identify what should be improved. The design optimization is achieved by reviewing the evaluation results, making improvements on the design and re-evaluates it. Validation of DECM is done by using a product case study. Results obtained from the case study showed that the method is able to achieve objectives of the product disassemblability.
