Abstract
In these years, increase of waste and exhaust of resource become major issues by the progress of mass productive, mass consumptive and mass waste life style. As the correspondence, the construction of circulation type society is required. For constructing such society, the consideration to 3R (Reduce, Reuse, Recycle) at the design and manufacture stage of the industrial product become very important. As the correspondence to Reuse and Recycle, the improvement of disassembling property of the products is especially required. Therefore, we propose the index that we assess at disassembling property of the products quantitatively. This index is that we roughly estimate the real disassembling time from the information on the design stage, as the disassembling time becomes the guideline that we assess at disassembling property. In this study, we aim at establishing the method of the determination of the index to apply the Design for Disassembly Assessment Index to various products
