Supply chain management in a crisis, when the only supplier of critical components suddenly went bankrupt

The article discusses the urgent issue of supply chain crisis management in the context of the sudden bankruptcy of a critical component's sole source, which is a significant threat to the operations of modern production and logistics systems. It analyzes the mechanisms of cascading failures resulting from the instant loss of a key supplier, and assesses the vulnerability of business processes historically dependent on monopoly suppliers. A comprehensive emergency response strategy is proposed, including auditing of critical materials, activation of standby arrangements, legal support for bankruptcy procedures to protect clients' property rights, and accelerated search for alternative suppliers using digital platforms and artificial intelligence technologies. Special attention is paid to preventive measures to increase the sustainability of supply chains. These include the early diversification of the supplier base, the creation of strategic stocks of vulnerable components, and the implementation of predictive analytics to identify financial and reputational risks associated with suppliers. In conclusion, practical recommendations are provided for the development and adaptation of business continuity plans to minimize production disruptions, maintain market position, and reduce financial loss in the event of unforeseen circumstances.
