サプライヤチェーンリスクが部品調達に与える影響度の評価及びレジリエンシ力の予測に関する研究

―サプライヤチェーンネットワーク，在庫と調達部品の違いによる生産の影響―

The global spread of the novel coronavirus infection (hereafter referred to as COVID-19) has caused supply chain disruptions. As a result, many global companies are reviewing vertical and horizontal relationships in their supply chains and emphasizing effective supply chain resilience measures, such as strengthening their business structures, diversifying their production sites and suppliers, and enhancing mutual aid systems with other companies.

This research assesses that the impact that the differences of procurement networks, inventory strategies and components have on carmakers when the external factors in the supply chain, such as the spread of COVID-19, become evident. The objective of the research is to evaluate the different effects of supply chain resilience measures and enable carmakers to supply components stably. For this purpose, a simple simulation model of a supply chain in the automotive industry was constructed and simulated, evaluated and analyzed based on scenarios reflecting the differences of the external factors in the supply chain.
