Abstract: This research focuses on the relative weight of indicators in raw material criticality assessment. The weight of the indicators configured for a criticality assessment varies based on the purpose of the evaluation and the stakeholders. That weight also has a significant impact on the assessment results. Consequently, it is essential to derive the weights using a scientific methodology quantitatively. We applied a fuzzy analytic hierarchy process (AHP) to secure a plausible weight for the appraisal of the raw material criticality in Korea. The results indicate that significant changes in the criticality are observed comparing the results from the previous method. We also set up three groups, those are government, industry, and research, to discuss the differences in a stakeholder's perspective. Our results and discussions on the difference in the weights and criticality for each group could help to establish policies to mitigate the raw material criticality.
