The Effect of Redundant Capacity Strategy on Supply Chain Resilience Using Simulation

Supply chain resilience is an important adaptive
capability and must exist in every supply chain network.
Disruptions that occur in the supply chain will have a major
impact on customer satisfaction. When customers are not
satisfied, a company may start dealing with the effects of
disruptions to its supply chain over time. Dissatisfied
customers will issue fines or switch suppliers to meet their
needs. Several strategies need to be implemented to minimize
the impact that occurs due to disruption, especially the impact
on customers. The total cost and total recovery time will be
affected by customer behavior when there is a disruption to the
supply chain network. Structural simulation will use agentbased

modeling by implementing a redundant capacity
strategy at each production plant. The percentage of
redundant capacity will vary with several different conditions.
Recovery time and total cost from the disruption that occurs
will be influenced by customer behavior. Customer behavior is
divided into two categories: critical customers and cumulative
customers. The two customer behaviors will have a different
impact on the strategy chosen. A supply chain resilience
assessment index will be obtained for time to recover, and the
total cost caused by disruption. The selection of the best
strategy must be known before the strategy helps the company
analyze recovery times in a disruptive situation using a
redundant capacity strategy.
