<p>Este trabalho tem como objetivo analisar, através de técnicas de simulação e de otimização, a dinâmica operacional do processo de atendimento de um pequeno posto de saúde localizado na região oeste paranaense. A simulação e a otimização foram executadas utilizando o pacote de simulação Arena®, que inclui o software de otimização Optquest. A metodologia utilizada é a de modelagem através de simulação computacional, de caráter quantitativo e é caracterizada como participativa. A aplicação destas técnicas em conjunto resultaram na otimização do número de agendamento de consultas médicas do posto de saúde.</p><p>Abstract</p><p>This work aims to analyze the attending process operational dynamics of a small health post located in Paraná West Region. Another objective is connect the concepts of simulation and optimization to maximize the number of scheduling appointments for the health post, within the limits of accommodation of the waiting room. The simulation and optimization were performed using the Arena ® simulation package, which includes the OptQuest optimization software. The methodology used was the modeling through computer simulation of quantitative character and it is characterized as participative. The application of these techniques all together resulted in the optimization of the number of medical appointment scheduling of the health post</p>

Abstract We have constructed a computer model, based on experimental data and the known properties of the enzymes involved, of the aspartate aminotransferase and alanine aminotransferase assays by the coupled-enzyme procedure of Henry et al. [Amer. J. Clin. Pathol. 34, 381 (1960)] to assay sera from normal persons and persons with liver disease or myocardial infarct. Observed inhibitions of aminotransferase activity were included in the models. When the computer models are combined with an optimization procedure, substrate concentrations that result in maximum enzyme activity for individual sera are obtained. Aminotransferase activity is not much affected by rather large changes in these concentrations around the optimum. The optimal concentrations we computed are close to those currently accepted. The computer methods involved may be applied to other assays, and factors other than reagent concentration may be optimized.

Thermodynamic Conditions

Heat recovery steam generators are successfully used in combined cycle power plants and many more applications. In a gas / steam combined cycle power plant the performance of bottoming cycle depends largely upon the effectiveness of HRSG. For a good HRSG in combined cycle power plants the heat exchange effectiveness should be as high as possible for maximum waste heat utilization and loss in the pressure of hot gases passing through HRSG should be small. In this paper, the computer simulation of HRSG has been carried out based on its thermodynamic study. An exhaustive generic computer code has been developed in C++ language for getting the critical information such as surface area required, number of tubes required, pressure loss, steam generation rate, effectiveness etc. for a single pressure & multi pressure HRSG. Results obtained using the code have been analyzed for varying operating thermodynamic conditions and different arrangements in HRSG. Preferable HRSG configuration and its thermodynamic analysis have been made using the computer code. Optimization of the HRSG design is carried out in respect to cost of HRSG using genetic algorithm.
