Using QFD and ANP to analyze the environmental production requirements in linguistic preferences

摘要

This study is to apply fuzzy quality function deployment (QFD) model with interdependence relations of environmental production requirements (EPRs) aspects and sustainable production indicators (SPIs) criteria for original equipment manufacturing (OEM) firm in Taiwan. At first, to facilitate the main issue of the QFD problem, however, the “Whats” question of EPRs and “Hows” problem of the SPIs have to be made, which are two major components and be emphasized on the house of quality matrices. In conjunction with fuzzy sets theory and analytical network process, the systematic analytical procedures are proposed. Subsequently, a case study demonstrated the evaluation process for identifying “Whats” and “Hows”. The results of empirical study show that (1) five aspects of EPRs are deemed to have priority to improve the environmental practice; and (2) twenty-two feasible SPIs criteria are practical indicated. In addition, it is suggested that case firm should aware attentively the SPIs and emphasize on exploiting these EPRs effectively. And develop the “Hows” issues, which should continuously strengthen of the EPRs, respectively.
