Abstract
A support system of design, paying attention to product re-manufacturing, was proposed to meet the current situation of short lifetime for products and the demand for recycling. An evaluation on the disassemblability of products was done for the purpose of an easy take-out of the target parts, and a strategic component design with consideration of the reusability of products and the technological progress was proposed. An experiment was carried out upon the disassembling of a printer, and it was found that the easiness of disassembling could be comparable between the calculated process from entropy and that of the practical operation.
