Der volle Inhalt der QuelleWe develop a series of process models to comprehensively describe and effectively manage innovative design in order to achieve adequate balance between innovation and control, following the design research methodology (DRM). Firstly, we introduce a descriptive model of innovative design. This model reflects the actual process and pattern of innovative design, locates innovation opportunities in the process and supports a systematic perspective whose focus is the external and internal factors affecting the success of innovative design. Secondly, we perform an empirical study to investigate how control and flexibility can be balanced to manage uncertainty in innovative design. After identifying project practices that cope with these uncertainties in terms of control and flexibility, a case-study sample based on five innovative design projects from an automotive company is analyzed and shows that control and flexibility can coexist. Based on the managerial insights of the empirical study, we develop the procedural process model and the activity-based adaptive model of innovative design. The former one provides the conceptual framework to balance innovation and control by the process structuration at the project-level and the integration of flexible practices at the operation-level. The latter model considers innovative design as a complex adaptive system, and thereby proposes the method of process design that dynamically constructs the process architecture of innovative design. Finally, the two models are verified by supporting a number of process analysis and simulation within a series of innovative design projects

Der volle Inhalt der QuelleThe aim of this work is to systematize the virtual creative process of packing, using a 3D modeling software as support tools for the creation and materialization of the idea. The current packing has been reformulated in a shorter time, being important for the success of the products and the companies. Thus, studies about how to develop packing in a fast and efficient way are fundamental, in order to reach the company’s strategic goals, a better interaction with people, being less aggressive to the environment inside the context they are consumed. With the available technological resources, the creation of packing is normally done with the help of software, although employing little or no systematization of the creative process. In order to approach the virtual creative process of packing, theoretical aspects regarding the packing design, creativity and creative processes, the tridimensional aspects and 3D virtual modeling were studied. Besides the theoretical aspects, a research with professionals with expertise in 3D virtual modeling was performed. Firstly, a qualitative analysis of these data was performed and, then, the interconnection between them was done in order to elaborate the ten procedures that can serve as a guide for the virtual creative process of the packing design. Then, these procedures were organized inside a methodology, which consists of Search, Connect, Create, Present. Its differential, compared to other methodologies, lies on the Create and Present phases, which involve the creation of packing using the possibilities of 3D modeling software. In the creation of the guides related to the creative process in software, the generalization of the procedures was targeted, because, in the context of the creation and materialization of the idea, different software can be used. To put this methodology into practice, a design of a perfume bottle, following the ten proposed guides, was accomplished. The guidance significantly contributed to lead and to organize the work, even inspiring the generation of ideas of the creative process and leading the activities up to the end of the work. It was also observed that graphical computation can significantly contribute with the design, increasing the creation and the materialization of packing. With these results, the creation time and the costs of creating prototypes can be reduced, besides improving the final visualization of the product.

Der volle Inhalt der QuelleMost successful manufacturing companies were initially formed around a unique or superior product design. As a result of this trend, many companies, especially in high-technology industries, considered design and marketing the company's primary functions. When the United States had superior manufacturing technological capabilities in the 1950's and 1960's, corporate management could systematically neglect manufacturing and still be successful. Manufacturing was treated as a service organization and evaluated in the negative terms of poor quality, low productivity, high wage rates, and so on. Manufacturing was not expected to make a positive contribution to a company's success. Recent successes of the Japanese in building higher quality, lower cost products show the critical error in this philosophy. Manufacturing is now a major factor in a company's competitive position (Priest, 1988).
Manufacturing strategies are the framework for accomplishing the long-term corporate goals for the manufacturing function. This framework helps to focus manufacturing goals and provides plans for integrating the necessary functions and resources into a coordinated effort to improve production. Communication of this strategy sets the right climate for the teamwork and long-term planning that are necessary in developing improved manufacturing capabilities. The strategy should be well publicized throughout the company, with regularly scheduled reviews to monitor progress toward the goals.
Recently, emphasis on manufacturing strategy, as advocated by leading scholars in the 1970's and 1980's, has been recognized as one way to regain the competitive advantage for American manufacturers. Work carried out recently at Harvard and Stanford by Porter (1985), Skinner (1985), Wheelwright and Hayes (1984) has given more attention to the central role and potential importance of manufacturing; this work helps to explain the relative success of Japanese and Gennan companies. Their work also sets a sound background for further research in this area. However, current studies in manufacturing strategy have delved into technology and financial considerations. But technology, capital, and work force are all planned by the people (managers) who are always located in some kind of organizational structure. Based on the experimental results proposed by industrial psychologists, this research is one step toward a quantitative study of organizational efficiency. Two major types of organizations, hierarchical (serial) and egalitarian (parallel), are investigated by applying simulation techniques. The variables controlled comprise organizational type, number of levels in a hierarchical structure, and number of participants. The research results are also applied to investigate the applicability of current design-to-manufacturing strategies, such as simultaneous engineering and concurrent design in firms. Suggestions on how to reduce the design-to-manufacturing time through appropriate organizational structures are presented following analysis of the simulation results.

In many real-life settings, we want to understand a physical relationship/phenomenon. Due to limited resources and/or ethical reasons, it is impossible to perform physical experiments to collect data, and therefore, we have to rely upon computer experiments, whose evaluation usually requires expensive simulation, involving complex mathematical equations. To reduce computational efforts, we are looking for a relatively cheap alternative, which is called an emulator, to serve as a surrogate model. Gaussian process (GP) is such an emulator, and has been very popular due to fabulous out-of-sample predictive performance and appropriate uncertainty quantification. However, due to computational complexity, full GP modeling is not suitable for “big data” settings. Gramacy and Apley (2015) proposed local approximate GP (laGP), the core idea of which is to use a subset of the data for inference and further prediction at unobserved inputs. This dissertation provides several extensions of laGP, which are applied to several real-life “big data” settings. The first application, detailed in Chapter 3, is to emulate satellite drag from large simulation experiments. A smart way is figured out to capture global input information in a comprehensive way by using a small subset of the data, and local prediction is performed subsequently. This method is called “multilevel GP modeling”, which is also deployed to synthesize field measurements and computational outputs of solar irradiance across the continental United States, illustrated in Chapter 4, and to emulate daytime land surface temperatures estimated by satellites, discussed in Chapter 5.

Der volle Inhalt der QuelleThe aim of this thesis is to explore how designers mentally categorize design information during early sketching performed in the generative phase. In conjunction with cognitive aspects of design, we proposed that cognitive and affective processes, involved in this specific phase, should be modeled through understanding designer's mental process and its relationship with early representations (sketches) together. A combination of action research approach and laboratory-based experiments was particularly appropriate for our study. Thus, first, a descriptive model of information processing involving memory theories drawn from cognitive psychology was developed. This model was refined and enriched via empirical studies with experts and novices in the product design domain. In order to formalize cognitive and affective processes of designers, we combined cognitive (concurrent verbalization protocol and questionnaires) and physiological (galvanic skin conductance and eye tracking system) methods. Subsequent analysis finally yielded a model depicting cognitive and affective processes of designers in the generative phase. As an application, based on our model, a list of specifications for developing computational tools dedicated to the generative phase has been applied and validated in the ''GENIUS'' project, which aimed to develop the system for supporting designer's activities in the early stages of design

Der volle Inhalt der QuelleThe globalization strengthens the necessity for companies to improve its processes and products in order to remains competitive and to attend expectations of a dynamic market and shareholders each time more demanding and eager to maximize their profits. The continuous improvement mentioned above, is not related only to the quality perceived by the final consumer, but also to the quality and reliability of the production processes. Therefore, as better processe the company gets, as better would be their final products and as lower would be the costs. However, the question is wheter a continuous improvement using Six Sigma could benefit from the design documentation for the target process returning also an improved documentation after the cycle is completed. This work considers the use of Petri Nets for production processes modeling - even if any other design and modeling representation would return similar results - supporting the Six Sigma methodology application. The main result is a proposition of continuous improvement life cycle that maintains the design documentation consistent and up-to-date. Thus, this work pursuits the integration between the teams that design processes and those who implement them in the manufacturing plant. To show the potential of the models analysis during Six Sigma projects a case study is analyzed for the Press Shop area in an Automotive Industry.

Crosscutting concerns are those that interact between several processes, but at the same time are not part of them. Traditional methods of process modeling do not have a special treatment to take care of crosscutting concerns, causing them to remain scattered throughout the process model, making it difficult to understand and maintain them later. In this sense, orientation to aspects is a paradigm that offers mechanisms to modularize transversal interests. In this dissertation improvements are proposed in a notation for process modeling that uses orientation to aspects, in order to generate models of easier understanding and facilitate its later maintenance. The methodology used was design science, which is more detailed in its respective section. Finally, a case study was carried out to evaluate if the proposed notation can produce a valid process model. In the conclusions chapter, it can be seen that the result was satisfactory, and that further work could be carried out in the future.

Der volle Inhalt der QuelleLa recente introduzione del concetto di Quality-by-Design (QbD) da parte della Food and Drug Administration e delle altre agenzie di regolamentazione farmaceutica ha l’obiettivo di migliorare e modernizzare gli approcci tradizionalmente utilizzati dalle industrie farmaceutiche per lo sviluppo di nuovi prodotti e dei relativi processi produttivi. Scopo dell’iniziativa è di incoraggiare le industrie stesse all’utilizzo di procedure sistematiche e basate su presupposti scientifici sia nella fase di sviluppo di prodotto e processo, che nella fase di conduzione del processo produttivo stesso. A tal proposito, le Agenzie hanno definito paradigmi e linee guida per agevolare l’implementazione di queste procedure in ambito industriale, favorendo una migliore comprensione dei fenomeni alla base dei processi produttivi, in maniera da assicurare un controllo stringente sulla qualità dei prodotti finali, in termini di proprietà fisiche, ma soprattutto di efficacia e sicurezza per i pazienti. Da un punto di vista ingegneristico, il Quality-by-Design può essere visto come il tentativo di introdurre principi di modellazione in ambiti di sviluppo e di produzione farmaceutica. Questo offre enormi opportunità all’industria farmaceutica, che può beneficiare di metodologie e strumenti ormai maturi, già sperimentati in altri settori industriali maggiormente inclini all’innovazione tecnologica. Allo stesso tempo, non va tralasciato il fatto che l’industria farmaceutica presenta caratteristiche uniche, come la complessità dei prodotti, le produzioni tipicamente discontinue, diversificate e in bassi volumi e, soprattutto, lo stretto controllo regolatorio, che richiedono strumenti dedicati per affrontare i problemi specifici che possono sorgere in tale ambiente. Per questi motivi, vi è l’esigenza di concepire metodologie che siano adeguate alle peculiarità dell’industria farmaceutica, ma al tempo stesso abbastanza generali da poter essere applicate in un’ampia gamma di situazioni. L’obiettivo di questa Dissertazione è dimostrare come la modellazione statistica, e in particolar modo i modelli a variabili latenti (LVM, latent variable models), possano essere utilizzati per guidare l’implementazione pratica dei principi fondamentali del Quality-by-Design in fase di sviluppo di prodotto e di processo e in fase di produzione in ambito farmaceutico. In particolare, vengono proposte metodologie generali per l’impiego di modelli a variabili latenti nelle tre aree principali sulle quali l’iniziativa del Quality-by-Design si fonda: il miglioramento della comprensione sui processi, la progettazione di nuovi prodotti e processi produttivi, e il monitoraggio e controllo di processo. Per ciascuna di queste aree, l’efficacia della modellazione a variabili latenti viene dimostrata applicando i modelli in diversi casi studio di tipo industriale, di laboratorio, o simulati. Per quanto riguarda il miglioramento della comprensione sui processi, nel Capitolo 3 è proposta una strategia generale per applicare LVM nello sviluppo di sistemi di produzione in continuo. L’analisi è applicata a supporto dello sviluppo di un processo industriale continuo di produzione di compresse su scala pilota. La procedura si basa su tre fasi fondamentali: i) una fase di gestione dei dati; ii) una fase di analisi esplorativa; iii) una fase di analisi globale. Viene mostrato come i parametri dei modelli costruiti a partire dai dati del processo possano essere interpretati sulla base di principi fisici, permettendo di identificare le principali forze motrici che agiscono sul sistema e di ordinarle a seconda della loro importanza. Questo può essere utile per supportare una valutazione dei rischi necessaria a definire una strategia di controllo per il processo e per guidare la sperimentazione fin dalle prime fasi dello sviluppo. In particolare, nel caso studio considerato, la metodologia proposta individua nel processo utilizzato per macinare le particelle di principio attivo e nella sezione nella quale il principio attivo è formulato le principali fonti di variabilità entranti nel sistema con effetto sulle proprietà fisiche del prodotto finale. Dall’analisi globale, è mostrato come l’utilizzo di modelli a variabili latenti a blocchi multipli permetta di individuare le unità del processo più critiche e, all’interno di ciascuna di esse, le variabili più critiche per la qualità del prodotto. Inoltre questi modelli si dimostrano particolarmente utili nell’identificare le traiettorie lungo le quali il processo si muove, a seconda delle proprietà delle materie prime e dei parametri di processo utilizzati, fornendo così uno strumento per garantire che l’operazione segua la traiettoria designata. Nell’ambito della progettazione di nuovi prodotti e processi, l’efficacia dei modelli a variabili latenti è dimostrata nel Capitolo 4, dove è proposta una procedura generale basata sull’inversione di LVM per supportare lo sviluppo di nuovi prodotti e la determinazione delle condizioni operative dei rispettivi processi di produzione. L’obiettivo della procedura proposta è quello di fornire uno strumento atto a dare un’adeguata formalizzazione matematica, in termini di inversione di LVM, al problema di progettazione, secondo gli obiettivi e i vincoli che il problema stesso può presentare. Dal momento che l’inversione di LVM può avere soluzioni multiple, vengono individuati quattro possibili problemi di ottimizzazione, tramite i quali effettuare l’inversione. L’obiettivo dell’inversione del modello è di stimare le condizioni ottimali in ingresso al sistema (in termini, per esempio, di caratteristiche delle materie prime o di parametri di processo) che assicurino di raggiungere la qualità desiderata per il prodotto in uscita. La procedura è applicata con successo in un caso studio industriale, per la determinazione delle proprietà delle materie prime in ingresso a un processo di granulazione a umido, con l’obiettivo di ottenere in uscita granuli con determinate caratteristiche di qualità. È inoltre esaminato il concetto di spazio nullo, lo spazio cioè cui appartengono tutte le soluzioni di un problema di inversione di LVM, che corrispondono ad uno stesso insieme di variabili desiderate (proprietà del prodotto) in uscita. In particolare, si dimostra come la definizione di spazio nullo presenti diverse caratteristiche comuni alla definizione di spazio di progetto (design space) di un processo, stabilita dalle linee guida delle Agenzie di regolamentazione, e come lo spazio nullo possa essere utilizzato al fine di una identificazione preliminare dello spazio di progetto. Al fine di avere una misura sull’affidabilità delle soluzioni del problema di inversione, viene proposta una strategia per stimarne le incertezze. Sono inoltre presentate alcune soluzioni per affrontare questioni specifiche relative all’inversione di LVM. In particolare, si propone una nuova statistica da utilizzare per la selezione del numero di variabili latenti da includere in un modello utilizzato per l’inversione, in modo tale da descrivere adeguatamente l’insieme dei regressori, oltre a quello delle variabili in uscita. In aggiunta, dato che a causa delle possibili incertezze del modello non è assicurato che la sua inversione fornisca una soluzione che consenta di ottenere le proprietà desiderate per il prodotto, è proposta una strategia per sfruttare la struttura di covarianza dei dati storici per selezionare nuovi profili di qualità per il prodotto, in modo da facilitare l’inversione del modello. Gli approcci proposti sfruttano i parametri del modello e i vincoli imposti per la qualità del prodotto per stimare nuovi insiemi di proprietà, per i quali l’errore di predizione del modello è minimo. Questo agevola l’inversione del modello nel fornire le proprietà del prodotto desiderate, dal momento che queste possono essere assegnate come vincoli rigidi al problema di ottimizzazione. Nel Capitolo 5 la procedura presentata al Capitolo 4 per l’inversione di LVM è applicata per progettare la formulazione di nuovi prodotti farmaceutici, in cui l’obiettivo è di stimare i migliori eccipienti da miscelare con un dato principio attivo e la loro quantità in modo da ottenere una miscela di proprietà adeguate per la fase di compressione. La procedura proposta al Capitolo 4 è ampliata al fine di includere i vincoli per la selezione dei materiali e di considerare gli specifici obiettivi che un problema di formulazione può presentare (per esempio, massimizzare la dose di principio attivo, o minimizzare il peso della compressa finale). L’inversione del modello è risolta come problema di programmazione non lineare misto-intera, per il quale è sviluppata un’interfaccia utente che consenta ai formulatori di specificare gli obiettivi e i vincoli che il problema di formulazione da risolvere può presentare. La metodologia proposta è testata in un caso studio industriale per progettare nuove formulazioni per un dato principio attivo. Le formulazioni progettate in-silico sono preparate e verificate sperimentalmente, fornendo risultati in linea con le predizioni del modello. Nel Capitolo 6 è presentata una diversa applicazione della procedura generale per l’inversione di LVM presentata al Capitolo 4. Il caso studio riguarda un problema di trasferimento di prodotto, in cui l’obiettivo è di ottenere nanoparticelle di diametro medio predefinito, tramite un processo di precipitazione con anti-solvente in un dispositivo obiettivo. La metodologia sfrutta i dati storici disponibili da esperimenti effettuati su un dispositivo di riferimento di diversa dimensione da quello obiettivo, e sullo stesso dispositivo obiettivo ma con una diversa configurazione sperimentale. Un modello di tipo joint-Y PLS (JY-PLS) è inizialmente utilizzato per correlare dati di diversa origine (per dispositivo e configurazione sperimentale). Quindi, la procedura presentata al Capitolo 4 viene impiegata per invertire il modello JY-PLS al fine di determinare le condizioni operative nel dispositivo obiettivo, che assicurino l’ottenimento di nanoparticelle di diametro medio desiderato. La convalida sperimentale conferma i risultati ottenuti dall’inversione del modello. Inoltre gli esperimenti consentono di convalidare sperimentalmente il concetto di spazio nullo, dimostrando come diverse condizioni di processo stimate lungo lo spazio nullo consentano effettivamente di ottenere nanoparticelle con le medesime dimensioni medie. La sezione finale di questa Dissertazione propone l’applicazione di LVM a supporto del monitoraggio e controllo di processo in operazioni farmaceutiche. In particolare, nel Capitolo 7, è affrontato il problema del trasferimento di modelli per il monitoraggio di processo tra impianti diversi. In questo caso il problema è di assicurare che l’operazione in un impianto obiettivo sia sotto controllo statistico fin dai primi istanti di funzionamento dell’impianto, sfruttando la conoscenza disponibile (in termini di dati) da altri impianti. È proposta una procedura generale basata su LVM per far fronte a questo tipo di problemi. La procedura identifica cinque diversi scenari, a seconda del tipo di informazioni disponibili (solo dati di processo o sia dati di processo sia conoscenza di base sul processo), della provenienza dei dati disponibili (solo dall’impianto di riferimento o sia dall’impianto di riferimento sia dall’impianto obiettivo) e dal tipo di variabili di processo considerate per la costruzione del modello (solo variabili comuni tra gli impianti o sia variabili comuni sia altre variabili). Per modellare in maniera congiunta i dati disponibili da impianti diversi, sono utilizzate analisi delle componenti principali (PCA) o modelli di tipo JY-PLS, a seconda che, per la costruzione del modello di monitoraggio, si considerino solo variabili comuni tra gli impianti (nel caso PCA), o sia variabili comuni sia altre variabili (nel caso JY-PLS). Le metodologie proposte sono verificate nel trasferimento di modello per il monitoraggio di un processo industriale di atomizzazione, dove il riferimento è un impianto su scala pilota, mentre l’impianto obiettivo è un’unità produttiva su scala industriale. Le prestazioni in fase di monitoraggio del processo su scala industriale sono soddisfacenti per tutti gli scenari proposti. In particolare, è dimostrato come il trasferimento di informazioni dall’impianto di riferimento migliori le prestazioni del modello per il monitoraggio dell’impianto obiettivo. Le procedure proposte sono inoltre applicate in uno studio preliminare per il trasferimento di sistemi di monitoraggio in processi discontinui, considerando come caso studio un processo simulato di fermentazione per la produzione di penicillina, in cui sono simulati due impianti differenti per scala e configurazione. Le prestazioni del sistema di monitoraggio indicano che, anche in questo caso, considerare nella costruzione del modello i dati disponibili dalle operazioni nell’impianto di riferimento rende il sistema più efficiente nella rilevazione delle anomalie simulate nell’impianto obiettivo, rispetto a considerare nel modello di monitoraggio i soli (pochi) dati disponibili dall’impianto obiettivo stesso.
Amziani, Mourad. „Modeling, evaluation and provisioning of elastic service-based business processes in the cloud“. Thesis, Evry, Institut national des télécommunications, 2015. http://www.theses.fr/2015TELE0016/document.
Der volle Inhalt der QuelleCloud computing is being increasingly used for deploying and executing business processes and particularly Service-based Business Processes (SBPs). Among other properties, Cloud environments provide elasticity at different scopes. The principle of elasticity is to ensure the provisioning of necessary and sufficient resources such that a Cloud service continues running smoothly even when the number or quantity of its utilization scales up or down, thereby avoiding under-utilization and over-utilization of resources. It is obvious that provisioning of elastic infrastructures and/or platforms is not sufficient to provide elasticity of deployed business processes. In fact, it is also necessary to consider the elasticity at the application scope. This allows the adaptation of deployed applications during their execution according to demands variation. Therefore, business processes should be provided with elasticity mechanisms allowing their adaptation to the workload changes while ensuring the desired functional and non-functional properties. In our work, we were interested in providing a holistic approach for modeling, evaluating and provisioning of elastic SBPs in the Cloud. We started by proposing a formal model for SBPs elasticity. To do this, we modeled SBPs using Petri nets and defined two elasticity operations (duplication / consolidation). In addition, we proposed to intertwine these elasticity operations with an elasticity controller that monitors SBPs execution, analyzes monitoring information and executes the appropriate elasticity operation (duplication/consolidation) in order to enforce the elasticity of SBPs. After facing the challenge of defining a model and mechanisms for SBPs elasticity, we were interested in the evaluation of elasticity before implementing it in real environments. To this end, we proposed to use our elasticity controller as a framework for the validation and evaluation of elasticity using verification and simulation techniques. Finally, we were interested in the provisioning of elasticity mechanisms for SBPs in real Cloud environments. For this aim, we proposed two approaches. The first approach packages non-elastic SBPs in micro-containers, extended with our elasticity mechanisms, before deploying them in Cloud infrastructures. The second approach integrates our elasticity controller in an autonomic infrastructure to dynamically add elasticity facilities to SBPs deployed on Cloud platforms

O presente trabalho foi desenvolvido com a microalga Chlorella minutissima com o objetivo de determinar as melhores condições operacionais de fotobioreatores tubulares descontínuos, tipo coluna de bolhas, para o crescimento celular e a produção de lipídeos em função das variáveis de processo: fluxo de CO2 na alimentação, concentração inicial de nitrato, concentração inicial de fosfato, suplementação (metais e vitaminas), temperatura e salinidade. Os experimentos foram planejados utilizando a metodologia de Taguchi. Os resultados obtidos mostraram que a configuração do fotobioreatores tubulares descontínuos, tipo coluna de bolhas, foi adequada para o cultivo da microalga Chlorella minutíssima, apresentando bons resultados de teor de lipídeos, da ordem de 37,08 ± 1,50 % em relação à biomassa seca ao final de 7 dias de cultivo. Definidas as condições ótimas de cultivo foi realizada uma reação como o óleo obtido, empregando catalisador químico (H2SO4). O resultado obtido demonstrou que o catalisador atuou de forma eficiente, convertendo os ácidos graxos em seus respectivos ésteres de etila. Outro fator importante de ressaltar foi a ausência de pigmentos presente no material lipídico, visto que o óleo extraído apresentou coloração amarelada similar aos óleos vegetais tradicionais, como por exemplo, o óleo de soja. Pigmentos quando presentes no material lipídico podem comprometer a conversão dos triglicerídeos em ésteres alquílicos (biodiesel). Chlorella minutissima apresenta vantagens adicionais perante a diversas matérias-primas lipídicas com presença de pigmentos. Para a avaliação da velocidade de crescimento populacional das microalgas foi considerado o modelo cinético de crescimento logístico. A partir desta investigação, verificou-se que o crescimento celular e a produtividade de lipídeos são significativamente dependentes da concentração inicial de nitrato, do fluxo de dióxido de carbono, da concentração de fosfato, da suplementação do meio e da temperatura. Os melhores valores obtidos, tanto para o crescimento quanto para a produtividade de lipídeos, foram para a concentração de nitrato no nível alto e os demais parâmetros significativos no nível baixo. Dessa forma, a metodologia e os resultados apresentados neste trabalho podem ser úteis na busca pela viabilização econômica da produção de biodiesel de microalgas, uma vez que a produção de biodiesel via microalgas ainda é um processo inviável devido aos custos.
The current work was developed with the microalgae Chlorella minutissima with the aim of determining the best operational conditions of discontinuous-tubular photobioreactors, bubble-column type, to the cell growth and production of lipids in relation to process variables: CO2 feed flow rate, nitrate initial concentration, phosphate initial concentration, supplements (metals and vitamins), temperature and salinity. The experiments were designed using Taguchi methodology. Results showed that the configuration of discontinuous-tubular photobioreactors, bubble-column type was adequate to the cultivation of microalgae Chlorella minutissima, presenting good results in terms of lipid content, of order of 37.08 ± 1.50% in relation to the dry biomass at the end of the 7 cultivation days. Once optimal cultivation conditions were established, a reaction with obtained oil was carried out using a chemical catalyst (H2SO4). Results showed that the catalyst acted in an efficient way, converting fatty oils in its respective ethyl esters. Another important factor worth noticing was the absence of pigments present in the lipid material, considering that the extracted oil presented a yellow color similar to traditional vegetal oils, such as soy oil. The presence of pigments in the lipid content may compromise the conversion of triglycerides in alkyl esters (biodiesel). Chlorella minutissima presents additional advantage in comparison to diverse lipid raw materials with the presence of pigments. The logistic growth was used as the kinetic model to evaluate the growth rate and speed of microalgae. From this analysis, it was possible to verify that cell growth and the productivity of lipids were significantly dependent on the initial concentration of nitrate, carbon dioxide flow rate, concentration of phosphate, supplementation of media and temperature. Best values obtained for growth as well as for lipid productivity were nitrate concentration in the high level and the other parameters were significant in the low level. Thus, the methodology and results presented in this work can be useful in seeking economic feasibility of production of microalgae biodiesel, since the production of biodiesel is currently is not viable due to the high costs associated to it.

Der volle Inhalt der QuelleSimulation models are widely used by industries as an aid for decision making to explore and optimize a broad range of complex industrial systems’ architectures. The increased complexity of industrial systems (cars, airplanes, etc.), ecological and economic concerns implies a need for exploring and analysing innovative system architectures efficiently and effectively by using simulation models. However, simulations designers currently suffer from limitations which make simulation models difficult to design and develop in a collaborative, multidisciplinary design environment. The multidisciplinary nature of simulation models requires a specific understanding of each phenomenon to simulate and a thorough description of the system architecture, its components and connections between components. To accomplish these objectives, the Model-Based Systems Engineering (MBSE) and Information Systems’ (IS) methodologies were used to support the simulation designer’s analysing capabilities in terms of methods, processes and design tool solutions. The objective of this thesis is twofold. The first concerns the development of a methodology and tools to build accurate simulation models. The second focuses on the introduction of an innovative approach to design, product and integrate the simulation models in a “plug and play" manner by ensuring the expected model fidelity. However, today, one of the major challenges in full-vehicle simulation model creation is to get domain level simulation models from different domain experts while detecting any potential inconsistency problem before the IVVQ (Integration, Verification, Validation, and Qualification) phase. In the current simulation model development process, most of the defects such as interface mismatch and interoperability problems are discovered late, during the IVVQ phase. This may create multiple wastes, including rework and, may-be the most harmful, incorrect simulation models, which are subsequently used as basis for design decisions. In order to address this problem, this work aims to reduce late inconsistency detection by ensuring early stage collaborations between the different suppliers and OEM. Thus, this work integrates first a Detailed Model Design Phase to the current model development process and, second, the roles have been re-organized and delegated between design actors. Finally an alternative architecture design tool is supported by an ontology-based DSL (Domain Specific Language) called Model Identity Card (MIC). The design tools and mentioned activities perspectives (e.g. decisions, views and viewpoints) are structured by inspiration from Enterprise Architecture Frameworks. To demonstrate the applicability of our proposed solution, engine-after treatment, hybrid parallel propulsion and electric transmission models are tested across automotive and aeronautic industries

Resumo: A utilização de técnicas de Fabricação Digital está cada vez mais presente no campo da arquitetura e construção por todo o mundo, devido aos avanços tecnológicos que os sistemas CAD (Computer-aided Design) e CAM (Computer-aided Manufacturing) têm proporcionado aos processos de concepção e produção da obra arquitetônica. As possibilidades que essas ferramentas oferecem aos arquitetos e projetistas abrem caminho para novas abordagens de projeto, que permitem o uso da produção automatizada sem a necessidade de uma padronização tão rígida como aquela imposta pelo sistema industrial. Entretanto, nota-se que a aplicação dos métodos de Fabricação Digital no processo de produção do espaço edificado no Brasil é lento, quando comparado a outros países onde a tecnologia necessária para o exercício da técnica já se encontra amplamente difundida. A presente pesquisa tem como foco investigar a aplicação da Fabricação Digital, por intermédio de processos file-to-factory na produção arquitetônica de elementos para a construção civil, mais especificamente com o uso de técnicas subtrativas de corte 2D. Após um levantamento sobre o estado da arte da área e o desenvolvimento de dois estudos de caso, o método utilizado foi a pesquisa-ação, por meio de um exercício de aplicação do conceito file-to-factory. O processo de projeto foi documentado detalhadamente e analisado para a sistematização dos procedimentos, que servirão de referência para futuras aplicações no campo da arquitetura. Espera-se, com isso, contribuir para a divulgação dessas novas tecnologias na produção arquitetônica no cenário brasileiro
Abstract: The use of Digital Fabrication techniques is increasingly present in the field of architecture and construction throughout the world. Systems such as CAD (Computer-aided Design) and CAM (Computer-aided Manufacturing) have provided technological advances to the architectural design and production process. The possibilities that these tools provide to architects and designers introduce new design approaches, which allow the use of automated production without the rigid standardization imposed by the industrial system. However, it can be noticed that the use of Digital Fabrication methods in the built environment production process in Brazil is slow when compared to other countries where the technology is widely incorporated. This research focuses on investigating the application of Digital Fabrication, through file-to-factory processes in the production of architectural elements for the construction industry, specifically with the use of 2D subtractive cutting techniques. After a survey on the state of the art in the field and two case studies, the method used was an action research through a file-to-factory exercise. The design process was documented in detail and analyzed in order to systematize the procedures as a reference for future applications in architecture. As a result we expect to contribute to the dissemination of these new technologies in architectural production in the Brazilian scenario

Les metodologies BIM i Lean tenen un impacte positiu en els projectes de construcció. A més, ni hi ha proves de l'aplicació conjunta de BIM i Lean; no obstant, es desconeix la relació empírica entre practiques Lean i els usos de BIM en fase de diseny. Tampoc existix una comprensió mes profunda dels fenómens socials que es generen entre els equips de diseny quan s'apliquen les metodologies de gestió BIM-Lean. Per tant, l'objectiu d'esta investigació es entendre l'impacte de les practiques de gestió de diseny Lean (LDM) i els usos BIM en l'interacció dels equips de diseny dels projectes de construcción. El métode de investigació te dos fases: 1) la creació de ferramentes per a evaluar el nivell d'aplicació de les practiques LDM i els usos BIM, i per a comprendre les interaccions en un equip de diseny; i 2) l'análisis de les relacions entre BIM, Lean i la interacció, basades en informació empírica de projectes de construcció en fase de diseny. Els resultats presenten un instrument d'evaluació d'usos del BIM i un questionari de practiques de LDM per a mesurar la gestió del diseny, i un método per a comprendre els diferents tipos d'interacció en un equip de diseny. Basades en les dades de 64 projectes, un análisis chi cuadrado va revelar 33 relacions empíricas entre els usos del BIM i les práctiques LDM; a més, l¿aplicació dels usos del BIM implica una major aplicació de les práctiques LDM. El projecte que aplica la gestió BIM-Lean obté nombroses interaccions en el seu equip de diseny; fluxes d'informació transparents, ordenats i estandarizats; un entorn de colaboració, confiança i aprenentatge; i una gestió del compromis. Tots estos elements d'interacció no son visibles en el projecte, en el que no es va aplicar la gestió BIM-lean.
[EN] Design teams of construction projects are composed of different stakeholders; this fact could make the interactions difficult. BIM and Lean methodologies have a positive impact on construction projects. Besides, there is evidence of the combined implementation of BIM and Lean; however, it is not known the empirical relationship between Lean practices and BIM uses in the design phase. Also, there is not a deeper understanding of the social phenomena that are generated among design teams when BIM-Lean management methodologies are implemented. Therefore, the objective of this research is to understand the impact of Lean design management (LDM) practices, and BIM uses in the interaction of construction project design teams. The research method has two phases: (1) the creation of tools to assess the level of implementation of LDM practices and BIM uses and to understand the interactions in a design team; and (2) the relationship analyses between BIM, Lean, and interaction, based on empirical information from construction projects in the design phase. The results present a BIM uses assessment tool and an LDM practices questionnaire to measure the design management and a method to understand the different types of interaction in a design team. Based on data from 64 projects, a chi-square analysis revealed 33 empirical relationships between BIM uses and LDM practices; also, the application of BIM uses implies a greater application of LDM practices. The project that applies BIM-Lean management achieves many interactions among its design team; transparent, orderly, and standardized information flows; a collaborative, trust, and learning environment; and commitment management. All these interaction elements are not visible in the project, where BIM-lean management was not applied.

Uma das grandes missões de um governo é de proporcionar bem-estar à população. Para alcançar esses objetivos é necessário desenvolver ações, as quais implicam vinculação de verba pública para assegurar as despesas que tais ações acarretarão. Sendo assim, nos órgãos públicos, como é o caso das universidades federais, é elaborado o orçamento anual, regido pela Lei Orçamentária Anual (LOA), a qual estabelece os créditos destinados aos diversos órgãos governamentais para que eles possam, então, desenvolver suas atividades. É nesse horizonte que este estudo aplica o princípio da Gestão de Processos, como ferramenta de gestão, para monitorar o desempenho da execução orçamentária, especialmente nos procedimentos que requerem ações entre unidades departamentais. Assim, o objetivo geral deste estudo foi o de analisar a gestão da execução orçamentária da Universidade Federal de Pernambuco (UFPE) e propor melhorias ao processo. Especificamente, o estudo identificou, descreveu e representou graficamente o processo de execução orçamentária da UFPE; analisou e apontou seus cenários atual e desejável em relação às suas etapas, ao tempo utilizado no desenvolvimento das tarefas e aos recursos humanos envolvidos; e apresentou uma proposição de indicadores de desempenho do processo na expectativa de que sirvam de recursos para monitorar a execução orçamentária das unidades gestoras de orçamento e da UFPE, em geral. Pesquisa de natureza aplicada, a coleta de dados combinou diferentes fontes de evidências: pesquisa documental, observação participante e questionários semiestruturados. Adotou-se abordagem qualitativa e quantitativa na análise dos dados, e utilizou a metodologia do Business Process Management (BPM) para descrição, representação e análise do processo. A proposição dos indicadores seguiu o modelo metodológico de Trzesniak (2014), e, portanto, os indicadores foram formulados com base em cinco dimensões: denominação, propósito, conceito, forma de apuração e metadados. A pesquisa apontou que o processo de execução orçamentária da UFPE tem potencial para se tornar mais ágil, eficiente e focado no usuário e que os indicadores de monitoramento propostos poderão acompanhar a gestão orçamentária.
One of the major missions of the government is to provide welfare to the population. In order to achieve this goal it is necessary to develop actions, which involve linking public funds to ensure resources for the development of such actions. Thus, public agencies - such as federal universities - prepare the annual budget in accordance with the Annual Budget Law (LOA), which establishes credits allocated to various government agencies so that they may develop their activities. This is the horizon to which this study applies the principle of process management as a management tool to monitor the performance of budget execution, especially procedures that require actions between departmental units. Therefore, this study aims at analyzing budget execution management performed by the Federal University of Pernambuco (UFPE) and proposing improvements to the process. Specifically, this study identified, described and graphically represented the budget execution process of UFPE. It analyzed and pointed out the current and desired scenarios regarding its stages, time spent in the development of tasks and human resources involved. In addition, it presented a proposal for performance indicators in an attempt to serve as resources for monitoring budget execution of UFPE's budget management units. This study is an applied research. Data collection combined different sources of evidence: document research, participant observation, and semi-structured questionnaires. It adopted qualitative and quantitative approach to data analysis, and used Business Process Management (BPM) methodology for description, representation and analysis of the process. Proposition of indicators followed the methodological model developed by Trzesniak (2014), and therefore indicators have been formulated based on five dimensions: denomination, purpose, concept, means of verification and metadata. The research indicated that UFPE's budget execution process has the potential to become more agile, efficient and focused on the user, and the proposed monitoring indicators may follow up the budget management.

Der volle Inhalt der QuelleThis Master Thesis presents the design of the core of a fixed point general purpose multimedia DSP processor (MDSP) and its instruction set. This processor employs parallel processing techniques and specialized addressing models to speed up the processing of multimedia applications.
The MDSP has a dual MAC structure with one enhanced MAC that provides a SIMD, Single Instruction Multiple Data, unit consisting of four parallel data paths that are optimized for accelerating multimedia applications. The SIMD unit performs four multimedia- oriented 16- bit operations every clock cycle. This accelerates computationally intensive procedures such as video and audio decoding. The MDSP uses a memory bank of four memories to provide multiple accesses of source data each clock cycle.
