Abstract
This study presents the design and qualitative evaluation of an enhanced supplier evaluation system tailored to the rubber chemicals industry. In response to the limitations of traditional models that often overemphasize cost and delivery metrics, the study adopts the ADDIE instructional design framework to develop a context-specific, multidimensional assessment tool. Drawing from qualitative data collected through focus group discussions and expert interviews across 35 rubber chemical firms in China, the research identifies key evaluation dimensions including product quality standards, quality control systems, cost transparency, logistics performance, and on-time delivery. The findings emphasize the increasing importance of supplier responsiveness, environmental accountability, and strategic alignment in supplier selection processes. Thematic analysis reveals a strong preference for transparent pricing structures, collaborative quality management, and digital procurement integration. Compared to previous models, the proposed system offers a more holistic and adaptive approach to supplier evaluation, aligned with industry-specific operational demands and sustainability objectives. The study contributes a practical framework for supplier assessment that supports improved decision-making, long-term collaboration, and enhanced supply chain performance.
