의사결정나무 추론을 이용한 공급사슬에서 무형자산의 시너지효과 분석

초록

This study attempts to analyze the synergistic effect of intangible assets on logistics efficiency in supply chains. Intangible assets are measured by investment in relationship, reduced control, knowledge/skill confidence, knowledge/skill link, reduction in opportunism, information sharing, benefit/risk sharing, decision sharing, which reflect the aspects of trust, commitment, and collaboration. Logistic efficiency is measured by order fulfillment, lead time, production flexibility, inventory turnover, overall cost, and backorder cost, which reflect the aspects of time, responsiveness, and cost. Unlike most former studies in SCM, we view trust between individual managers in supplier and buyer firms, and evaluate suppliers' trust on buyers, because suppliers can better observe supply chain processes and try to solve efficiency problems. Decision tree induction is adopted to analyze the interaction between independent variables and to figure out how these variables must be joined to give an effect on performance. The analysis results indicate that investment in relationship is the most influential variable in explaining the performance in all three aspects of supply chains. Secondary variables that give synergistic effect by combining with affective trust such as investment in relationship include collaboration variables such as decision sharing, benefit/risk sharing, and information sharing.
