There are many ways to be able to enhance the supply chain resilience: Ÿ Maintaining the redundant in inventory level and capacity, so as to meet the temporary and emergency demands for materials or final products when unexpected events happen
Ÿ Adopting the multi-vendor strategy, which is that, the supply of materials or services does not rely on a single supplier excessively, so as to make the procurement from other suppliers when the major supplier has problems
