AHP를 활용한 공급사슬 중단 위험의 파급효과 발생 요인 분석

This study aims to analyze the main causes of ripple effect and their degree of risk propagation under supply chain disruption. To achieve the purpose of this study, we derived the priority of main causes for managing ripple effect focusing on domestic manufacturing companies and logistics & distribution companies using AHP method. The main results of this study are as follows. As a result of multiplying the weights of the 1st and 2nd layers, it was confirmed that the structural vulnerability factor of the supply chain had the highest weight value. In addition, the results of group comparison by the type of industry, business size, and manufacturing category are as follows. First, the uncertainty of suppliers and buyers was found to be important for logistics and distribution companies to manage the ripple effect. Second, while large enterprises evaluated the sub-factors of supply chain structural vulnerability as the most important, SMEs(Small and Medium-sized Enterprises) were identified to require more careful management of complexity and dependence on suppliers and buyers. Third, unlike consumer goods manufacturing, the three major factors of assembly and processing manufacturing are all related to supply chain structural vulnerability. This study provides academic implications by identifying the factors of the ripple effect and quantifying the degree of risk propagation. In addition, it is proposed to effectively manage the main causes of ripple effects according to industry type, business size, and characteristics of each company.
