Inventory Optimization in Pharmacy Using Inventory Simulation-Based Model During the Covid-19 Pandemic

The problem that often occurs in raw material inventory is overstock or stockout conditions. healthcare industry, including pharmaceuticals, has been experiencing uncertainty since the Covid-19 pandemic. Then impacts panic buying and stockpiling, which can lead to unpredictable spikes demand, stockouts, disruptions system. research was conducted at ABC Pharmacy Yogyakarta, experienced this problem. In study, optimization of drug supply carried out by measuring ware­house capacity, safety stock, increasing number orders reorder points using Min-Max economic order quantity models. A simulation optimi­zation planning Monte Carlo see projections for next three months. Overall, EOQ model shows most optimal results showing average total cost Rp. 103,579, where represents lowest costs when compared other It also 86% more efficient than model. Comparison methods are calcu­lated according current demand method, produces minimum cost, followed company's initial Min Max method.
