Abstract

Inventory management is one of the main tasks that the pharmacy department has to carry out in a hospital. It is a complex problem that requires to establish a tradeoff between different and contradictory optimization criteria. The complexity of the problem is increased by the constrains that naturally arise in stock management problems such as variable delays or stochastic demands. In this work we propose to apply model predictive control (CPBM) to the pharmacy department inventory management problem from a risk mitigation perspective. Mitigation actions are executed to reduce the impact of the possible risks that may occur. Hence, new decision variables are added to the initial problem. Given that these variables may be boolean, the problem is formulated as a mixed integer quadratic programming. The proposed methodology is put to test in simulations based on data proceeding from a real hospital.

La tabla 3 muestra cuatro casos de simulaciones para distin-tos valores de stock de seguridad, detallando también, la media y desviación del stock. A medida que se aumenta este valor, el número de casos que no cumplen la restricción disminuye. Por otro lado, también se incrementa la media del stock al incre-mentar el stock de seguridad; se trata de determinar un balance entre ambos términos.
