Minimization of Drug Shortages in Pharmaceutical Supply Chains: A Simulation-Based Analysis of Drug Recall Patterns and Inventory Policies

Table 4

Optimal CSL for varying ratios of shortage and inventory costs under different disruption patterns as defined by the expected number of recall disruptions ().
