Item Aplicação da Programação Linear no Controle de Estoque de Peças de Reposição em uma Organização Aérea: Estudo de Caso(Instituto de Tecnologia, 2018) Alexandra Priscila Costa Pessoa; Rui Nelson Otoni MagnoThe research addresses the application of Linear Programming as a tool to optimize spare parts inventory control in an airline organization. The study seeks to minimize costs and maximize logistics efficiency, considering operational constraints and the demand for parts. The methodology employed involves the formulation of mathematical models based on Linear Programming to determine the ideal quantity of parts to be kept in stock, ensuring the necessary availability without excesses that could financially impact the organization. The case study presents a practical application of the proposed modeling in an airline company, demonstrating the benefits of the approach. The results indicate that the use of Linear Programming can lead to a significant reduction in operating costs, improving inventory planning and management. The research contributes to the literature on supply management by providing a model that can be adapted to different business contexts that deal with the maintenance and replacement of critical parts.Item ANÁLISE E IDENTIFICAÇÃO DO MODELO DINÂMICO DO PROCESSO DE COMBUSTÃO EM UM CALCINADOR INDUSTRIAL(Instituto de Tecnologia, 2015) COSTA, Daniella dos Santos Ferreira; SILVA, Orlando FonsecaThis work was developed at Hydro Alunorte's alumina refinery in Barcarena — PA, specifically in the calcination area. Calcination is the process by which all the free water or combined hydrate (Al₂O₃·3H₂O) is eliminated, forming aluminum oxide or simply alumina (Al₂O₃). This reaction requires heating in the combustion chamber with controlled temperature around 1000ºC, located within the stationary fluidized bed calciners. Inside the furnace, a combustion reaction takes place with HFO (Heavy Fuel Oil) as fuel and atmospheric air, which is captured via blowers. The main objective of this work is to identify a representative mathematical model for the combustion process that happens inside the furnace, to further optimize it, thus increasing the energy efficiency of the calciner oven.
