Abstract
This article covers the inventory management of healthcare supplies problem. Based on the mathematical programming model set out by With this simulation model, a purchases plan with 21 healthcare supplies was obtained that contemplates all the problem's restrictions: purchasing policy (safety stock, available budget); the warehouse's physical reality (warehouse capacity); characteristics of supplies (useful life, service level); and suppliers (price, capacity and size of lots or rounding value). Different indicators were also considered, such as service levels, costs of purchases, stockouts costs and inventory maintenance costs. The results obtained with the simulation model came very close to the mathematical programming results, but the computing times were considerably shorter.
