Aplicação da teoria das restrições utilizando a simulação na gestão da capacidade de uma unidade de pronto atendimento

Abstract

The study in question deals with the analysis of the capacity of casualty department (CD), for its realization was used the theory of constraints, their approach has allowed find out the point of greater demand on the system. They were found along with the discrete simulation, alternative arrangements might be tested, virtually without prejudice to attendance. Through a survey of documentary data and using the tools of statistics as a test of comparison of means, statistical process control (SPC), and component analysis, was able to identify the process of care in which it subordinates the other, ie, the bottleneck the acting unit so that there the efficiency of the unit as a whole increases. This preliminary study allowed the survey focus assistance time in days as priorities, focusing on the time of the survey process as input data for simulation to optimize the time available, with minimal inconvenience to the unit which deals with life and persons must work the least disturbance as possible. So, alternatives are given to decrease long queues and high waiting times which many citizens go through at the CD. The responses generated by ARENA® show a relevant improvement on performance of system, although the average waiting times remain high when thought that we are working in a medical service, and that is essential and the clinical profile of a patient may report worsening, it opens scope for future work in area to continuously improve the service.
