中文摘要：

基于生物细胞弹性理论建立了供应链弹性模型，研究了制造商与不同供应商之间的合作关系在需求中断事件的冲击下如何影响供应链的弹性．研究结果表明：加强与自身弹性更强的供应商的合作更能够提高供应链弹性，降低供应链的损失；当供应链上下游企业之间的合作程度较低时，加强两者之间的合作能够迅速提高供应链弹性，而当上下游之间的合作程度较高时，继续加强合作对供应链弹性的影响较小，因此在一定范围内增强上下游之间的合作关系是提高供应链弹性相对经济有效的方法．

英文摘要：

A supply chain resilience model is established based on the biological cellular resilience theory to analyze the impact of the supplier relationship on supply chain resilience. A scenario where the market demand is changed suddenly by some undesired events is considered. The results reveal that enhancing collaboration with a more resilient supplier can significantly improve supply chain resilience and reduce supply chain losses. It is also found that enhancing the supplier relationship can significantly benefit supply chain resilience if the collaborative intensity is relatively low, and it has less effect if supply chain members have already collaborated closely. Thus, enhancing the supplier relationship to a limited intensity is a relatively effective and economic method to strengthen supply chain resilience.
