A SYSTEMS DYNAMICS SIMULATION IN HOSPITAL LOGISTICS: STOCK AND CAPACITY MANAGEMENT INTEGRATED VISION
The main objective of this paper is to develop a simulation model, using dynamic systems to analyze different hospital logistic policies. The model allows an integrated analysis of how the management of different stock and capacities policies impacts in the hospital attendance costs. The main factors of this process considered in the modeling are the medicine stock management and attendance capacity, defined as the specialized work source availability (physicians). Other important factors in this process were considered as capacity restrictions: hammock and equipments availability. In order to show the model suitability, the Emergency Room of Unicamp Clnicas Hospital case was studied. Different scenarios analyses were done combining stock policies, capacities and their costs. Using these results, integrated strategies of stock policies and capacities were proposed in order to reduce costs.
