Systematization of product life cycle technology utilizing the QFD method

The environmental QFD was developed to satisfy the requirements to new products by extracting technical assignment, but it is difficult to do systematization of technology assignment. For example, technology assignment to sating one requirement is not only one by any means. There is a technology group that can contribute to one requirement in the same way, even if the technologies in one group come from a lot of different areas. Rearranging and systematization of technologies have been demanded traditionally, however, the approach to be settled systematically has not been suggested so far. This paper suggested the systematization technique related to product life cycle engineering utilizing the quantification type IV and the environmental QFD. There was common tendency about technical systematization. Therefore some systematization of technologies is possible. And the superposition with importance and systematization gives us a suggestion about alternative technologies from a viewpoint of target achievement.
