Aplicação de métodos com múltiplos critérios em uma empresa petroquímica

The corporate world is increasingly competitive, and companies need to go deep into the routines and work them in order to understand them fully. The market is demanding more than simple improvements that bring advances - of small or great expression; however, in a longer term it will no longer meet the ideology of the market. Companies aimed at the world class must focus on projects that will continually bring returns to the company. As previously mentioned, understanding the processes in minute details is of paramount importance, as this knowledge can be acquired by analyzing the decisions that are necessary during the process. Once the complexity increases, the quantity and difficulty of the criteria that influence them grow accordingly. At this time, methods and tools that assist decisionmaking processes can be used as, besides being able to provide the best decision methods of MCDA (Multiple Criteria Decision Aid), they provide clear and assertive understanding of the whole decision process. In developing this study, we sought to explore the AHP (Analytic Hierarchy Process) method (a MCDA method) in the choice of access service, featured by the support service used to reach and be the basis of repairs in places of difficult access. This work proposes a study of the quantitative modeling approach in a real routine activity for a Brazilian petrochemical company. Decision-making processes are explored when we seek to analyze not only the decision makers but also what directly influences them on the use of the AIJ method. Once this is achieved, the understanding of decision-making is substantiated

Investigação dos métodos de separação, uso e aplicação da Lignina proveniente da biomassa lignocelulósica

This study investigated the main methods of separation of components of lignocellulosic biomass, with an emphasis on obtaining lignin and its application. The work was developed based on the concept of Biorefinery proposing full use of renewable raw materials and / or the use of lignocellulosic agricultural residues by biochemical or biotechnological conversion in obtaining high value added products with minimal environmental impact. From this premise, a literature review was performed in refereed journal articles and theses in order to gather enough material for critical analysis of usual and alternative methods in the literature. When researching methods that add value to lignin, it was found that with the technology found today, the cost required to have a degree of competitiveness is still too high, preventing much of the process. However, the isolated lignin can be used as raw material in the production of numerous types of biocomposites and polymers and other products such as phenols, benzene, dispersants, vanillin, emulsifying agents, antioxidants, pesticides, fertilizers, charcoal, concrete additives, among others. As an industrial production level is necessary, because the consumption of biomass will only grow over the years, it is necessary that new methods or technologies to be created in order to facilitate the extensive use of lignocellulosic biomass

Gráficos de T² para o monitoramento de processos multivariados autocorrelacionados

In which refers to statistical process control, the analysis of univariate cases is not enough for many types of company, being necessary to resort to multivariate cases. Besides, it is usually supposed that the observations are independent. However, the violation of this hypothesis indicates the existence of autocorrelation in the process. In this work, by a basic quantitative approach for an exploratory and experimental research, the study target are the multivariate autocorrelated control charts, using Hotteling T². The ARL values were collected by simulations of a computational program on FORTRAN language, with objective of studying the charts properties, in addition to compare with the
