공급 네트워크의 위상구조, 계층별 규모, 규모 비율과 고장 대응 전략의 효과성: 시뮬레이션을 이용한 탐색적 연구

초록

This study exploratorily analyzes the effects of supply network topology, tier-level size, and size ratios on the effectiveness of disruption mitigation strategies. To this end, an agentbased simulation was conducted by extending the beer game into a network structure, and the results were examined using hierarchical regression analysis. The effectiveness of mitigation strategies was measured as the reduction in backorders relative to a no-response strategy. The results show that mitigation strategies were consistently less effective in scale-free networks than in random networks. An increase in the size of the upstream tier where disruptions occur (wholesalers), reduced effectiveness in random networks, whereas an increase in the size of the downstream tier implementing mitigation strategies (retailers), enhanced effectiveness. Tier-level size ratios also showed differential effects depending on network topology and disruption type. This study suggests that improving supply network resilience is not merely a matter of selecting individual strategies, but also of ensuring alignment among network structure, tier-level size, and mitigation strategies.
