Análise econômica financeira comparativa da autoprodução direta ou conectada no SIN - um estudo de caso. / The comparative economic financial analysis of the direct self production or connected to SIN (National Interconnected System) case analysis.

Midea, Leonardo Granada 26 May 2009 (has links)
Este trabalho tem como objetivo principal verificar a viabilidade econômica financeira da autoprodução direta e interligada, isto é, elaborar uma comparação entre uma usina hidrelétrica ligada diretamente à unidade de consumo, e uma usina ligada ao Sistema Interligado Nacional, com potência e energia asseguradas. Para isso, foram utilizados, como premissas, uma indústria de alumínio que, como parte integrante dos grandes consumidores de energia brasileira, é um tipo de indústria eletro-intensiva, e emprega milhares de pessoas direta e indiretamente; também uma usina hidrelétrica, que neste trabalho foi a UHE Piraju, usina de concessão da CIA BRASILEIRA DE ALUMÍNIO, que gentilmente cedeu os dados de geração física real. Foram adotadas as seguintes metodologias para comparação da viabilidade, utilizando um cenário de geração e preços SPOT dos anos de 2006 e 2007: (i) Autoprodução Direta: Geração física real, comercializando excedentes e comprando energia do mercado ao preço SPOT quando necessário, e considerando todos os encargos e benefícios deste tipo de ligação; (ii) Autoprodução Conectada no SIN: Energia Assegurada Sazonalizada em 3 cenários distintos, Flat, com sazonalização moderada e sazonalização otimizada, considerando também os custos de conexão e encargos pertinentes para cada cenário. Os resultados apresentados mostram que, por pouca margem de diferença, foi mais vantajoso o cenário com a energia assegurada otimizada, porém, é possível verificar que, ponderando os resultados apresentados nos diversos cenários, verificamos que é mais viável a usina ligada diretamente à carga, pois a previsibilidade do mercado de preços de curto prazo é pequena, e dificilmente se acertaria com precisão os PLD´s registrados no ano seguinte ao da sazonalização. Contudo, o Decreto no 5.163, de 30 de Julho de 2004, através do Artigo 71, somente permite que usinas sejam ligadas diretamente à carga se estiverem dentro do mesmo sítio. O proposto é a inclusão de um novo parágrafo no Artigo 71 com condições de economicidade para a permissão da ligação da usina diretamente ao consumo. / The main goal of this study is to verify the economic financial feasibility of the direct self production, it means, of a hydropower unit directly connected to a consumption unit and to a hydropower unit connected to the SIN, with guaranteed power and energy. For this purpose, the study used as pattern an aluminum industry, which, as part of the Brazilian hall of the major energy users, a type of electric-intensive industry, and that involves thousands of employees directly and indirectly, as well as an hydroelectric power unit, which in this study was the UHE Piraju, the energy authorized supplier unit of the CIA BRASILEIRA DE ALUMÍNIO, who gently provided the real generation data. The following methodology were adopted to compare the feasibility, using a generation scenario and SPOT values of 2006 and 2007: (i) Direct Self Production: Real generation, trading leftovers and acquiring market energy at SPOT values, when required, and considering all costs and benefits of this type of connection; (ii) SIN Connected Self production: guaranteed seasoned energy in different scenarios, Flat, with seasonalization moderated and seasonalization optimized, also considering the connection and applicable costs for each scenario. The presented results indicated that, for a small difference, the most advantageous scenario was the one with optimized guaranteed energy, however, it is possible to verify that evaluating the presented results in the different cases, it was verified that is more feasible the unit directed connected to a demand, since the forecast of short term values market is small, and it would hardly precise ascertain with the registered PLD (Settlement Price for the Differences) in the following year of the seasonalization. However, the Act n. 5.163, July 30, 2004, through the Article 71 only allows power units to be connected to the demand if they are in the same site. The proposal is the inclusion of a new paragraph in the Article 71 with economic conditions in order to allow the connection between the power unit to the consumption.

Redução de custos através do manufacturing execution system (MES) e sua integração com o enterprise resource planning (ERP) / Costs reduction through manufacturing execution system (MES) and integration with enterprise resource planning (ERP)

Matsubara, Rafael Yuji 04 December 2014 (has links)
A dissertação aborda o estudo sobre as principais características observadas sob a perspectiva da gestão de custos em indústrias de manufatura discreta, em especial considerando uma possível integração dos Sistemas Enterprise Resource Planning (ERP) com os chamados Manufacturing Execution Systems (MES). Este estudo procurar elucidar acerca das iniciativas orientadas à redução de custos, especialmente aquelas aplicas em manufaturas do tipo discreta. Por meio do método de estudo múltiplo de casos foram coletados dados a respeito da implementação do MES e seus impactos sobre a redução de custos em três organizações, para que fossem debatidas as visões de diversos gestores, verificando se as hipóteses levantadas ao longo do projeto são confirmadas. Por fim, os resultados observados foram analisados e discutidos, e as conclusões apontam que o uso do sistema MES pode contribuir ou possui potencial para reduzir os custos e também para aumentar o controle da gestão. No entanto, foi possível observar também que a implantação de sistemas deve ser acompanhada de mudanças de processos e de cultura, que propiciem de fato a redução de custos nas empresas. Foram propostas novas possibilidades para que seja possível a continuidade de outros estudos neste sentido, de forma que as organizações possam explorar novas possibilidades, aperfeiçoando os sistemas ou desenvolvendo mudanças em seus processos. / The dissertation describes the study on major features achieved from the perspective of cost management within discrete manufacturing industries, especially considering a possible integration between Enterprise Resource Planning (ERP) systems with so-called Manufacturing Execution Systems (MES). This study seeks to enlighten a few initiatives on the subject concerned to cost reduction management belonged to the company, especially those applied among manufacturers whose type is settled as discrete. By using the multiple case study method, several data regarding MES implementation and also its impacts on cost decrease were gathered within three enterprises, and therefore used for debating some standpoints from several managers and verifying whether the assumptions made throughout the article are confirmed. Finally, the results obtained along this study were analyzed and discussed, and such findings lead to idea that MES system use can concur or has the potential to decrease costs and also enhance the management control. However, it was also possible to behold that systems implementation should be followed by a culture and processes changes as well, that surely provide cost cutting among companies. It was proposed some other improvement possibilities in order to make possible the development of new efforts in this regard, in a way that enterprises are able to explore new paths, enhancing the systems or even developing changes in their processes.

Díaz Salazar, Roberth Fabrizio, Gambetta Carpio, Marcelo Fabrizio 29 October 2021 (has links)
El sector plástico a nivel mundial, es uno de los que más genera desperdicios, ya que la población los desecha inadecuadamente, de manera que las leyes actuales tengan como objetivo minimizar el uso de estos productos en base a este material o que estos sean reutilizables. Es por ello que, en el presente artículo se propone un modelo para el aumento de la rentabilidad en las empresas PYMES del sector plástico utilizando metodología Lean-Green. Las herramientas a utilizar será las 5´s, KanBan para el control de inventarios y TPM para estandarizar nuevos procesos de mantenimiento correctivo y preventivo, como aporte añadido se incluirá un proceso de economía circular para la reutilización de los productos comercializados, para generar menores consumos y desechos sólidos que perjudiquen al medio ambiente, cumpliendo con los estándares impuestos. Los resultados obtenidos fue una reducción del 11%” en la adquisición de materia prima y repuestos para mantenimiento de máquinas, también una reducción del número de fallas por maquina en 4%. / The plastic sector worldwide is one of the sectors that generates the most waste, since the population disposes of it improperly, so that the current laws will have the objective of minimizing the use of these products based on this material or that they are reusable. That is why, in this article, a model is proposed to increase profitability in SME companies in the plastic sector using Lean-Green methodology. The tools to be used will be the 5's, KanBan for inventory control and TPM to standardize new corrective and preventive maintenance processes, as an added bonus a circular economy process will be lost for the reuse of marketed products, to generate lower consumption and solid waste that harm the environment, complying with the imposed standards. The results obtained were an 11% reduction” in the acquisition of raw material and spare parts for machine maintenance, as well as a 4% reduction in the number of failures per machine. / Tesis
