Planejamento das manutenções preventivas em unidades hospitalares

Abstract

Clinical Engineering is responsible for the preventive maintenance of medical equipment in hospital units. It happens that in most hospitals preventive maintenance is empirically programmed manually, which ends up not providing the optimal solution for the equitable distribution of tasks during the year, causing a variable demand for labor. The objective of the present work is the use of a mathematical tool to reorganize preventive maintenance (fixed activities) of hospital units, with the consequent possibility of optimizing the workforce in the Clinical Engineering sectors. Integer Linear Programming (ILP) techniques are used, with the inclusion of restrictions related to collaborators, preventive schedules and frequency, implemented in the Lingo 18.0 solver. To validate the model, information obtained from 4 hospital units served by the same outsourced company in the city of Curitiba, Paraná, is used, making it possible to compare the model’s solution with information from the current situation. The optimal solution provided by the modeling confirms that there is great scope for optimization of the tasks and personnel of the Clinical Engineering with implantation of the best possible resulting solution, considering the established restrictions.
