L’audit, c’est un outil de gestion très important pour que les organisations puissent accomplir la réussite. Selon le fait qu’il n’y a pas des modèles d’aide à l’audit, il existe une opportunité de recherche. En considerant les Méthodes d’Aide à la Décision, il y a des plusieurs type d’applications. L’objectif de la recherche c’est la proposition d’un modèle capable de sélectionner des processus pour faire l’audit dans une distributeur de carburant en considerant la prise de décision en groupe. La modélisation normative empirique c’est la méthode de recherche utilisée. Un modèle qui utilise l’Analytic Hierarchy Process (AHP) et la prise de décision en groupe a été proposé face aux difficultés d’un département d’Audit Interne. Le modèle proposé présente les poids des processus et permet leur priorisations dans un scénario determiné. Pour l’application de ce modèle présenté, on a utilisé cinq critères et 26 alternative (processus). L’information de jugement a été bien founi par trois spécialistes du département. Quelques rendez-vous avec les participants ont été pris pour obtenir et réviser les donnés ainsi que discuter les résultats. Les résultats obtenus par le modèle permettent d’identifier les processus qu’il faut plus d’attention. L’équipe a considéré le modèle comme une proposition d’aide à la prise de décision très pertinent pour le département d’Audit Interne

Because the high consumption of welded pipe for exploration and conduction oil and gas, optimization of manufacturing processes is necessary to obtain better productivity, efficiency and cost reduction. The objective of this study is to analyze the forms of heat transfer during the welding of pipes using longitudinal submerged arc process them to propose a model for the temperature distribution in the welded region. For this analysis are addressed as the heat transfer modes operate in the specified welding process and the necessary considerations for the mathematical model were obtained. The calculations were performed and the simulations needed to obtain the temperature distribution in the tube were carried out. Therefore, the practice was satisfactory and the results showed a range of temperatures along the pipe for a particular model and the future suggestions for improvement of this work

Neste trabalho, foi estudado o modelo matemático oscilatório proposto por Daugulis et al. (1997) referente a um processo contínuo de fermentação alcoólica, de modo a compreender sua estrutura, variáveis, fenômenos e hipóteses postuladas. O estudo foi realizado de modo a compreender como os mecanismos de inibição por produto e substrato, e como os mecanismos adaptativos do microrganismo são levados em consideração pelo modelo, resultando no comportamento oscilatório desejado. Por fim, foram realizadas simulações com perturbações do tipo degrau na taxa de diluição e na concentração de substrato na alimentação, de modo a extrapolar o comportamento do modelo.

The building budgeting quickly and accurately is a challenge faced by the companies in the sector. The cost estimation process is performed from the quantity takeoff and this process of quantification, historically, through the analysis of the project, scope of work and project information contained in 2D design, text files and spreadsheets. This method, in many cases, present itself flawed, influencing the making management decisions, once it is closely coupled to time and cost management. In this scenario, this work intends to make a critical analysis of conventional process of quantity takeoff, from the quantification through 2D designs, and with the use of the software Autodesk Revit 2016, which uses the concepts of building information modeling for automated quantity takeoff of 3D model construction. It is noted that the 3D modeling process should be aligned with the goals of budgeting. The use of BIM technology programs provides several benefits compared to traditional quantity takeoff process, representing gains in productivity, transparency and assertiveness
