number of parts per product. For the evaluation items of parts shape, fastening method
and washing convenience, the evaluation results for each factor were quantified
by scoring using the scoring table. The criterion of remanufacturing convenience
score for each factor was derived from AHP questionnaire for expert interview and
remanufactured workers.
