A software architecture is one of the first steps towards a software system. A software architecture can be designed in different ways. During the design phase, it is important to select the most suitable design of the architecture, in order to create a good foundation for the system. The selection process is performed by evaluating architecture alternatives against each other. We investigate the use of continuous simulation of a software architecture as a support tool for architecture evaluation. For this purpose, we study a software architecture of an existing software system in an experiment, where we create a model of it using a tool for continuous simulation, and simulate the model. Based on the results from the simulation, we conclude that the system is too complex to be modeled for continuous simulation. Problems we identify are that we need discrete functionality to be able to correctly simulate the system, and that it is very time-consuming to develop a model for evaluation purposes. Thus, we find that continuous simulation is not appropriate for evaluating a software architecture, but that the modeling process is a valuable tool for increasing knowledge and understanding about an architecture.

Mestrado em Engenharia e Gestão IndustrialNas últimas décadas, a evolução da indústria alcançou uma extrema importância na nossa vida pessoal e também no comportamento empresarial. O conjunto de ferramentas existentes nos computadores representam um papel fundamental na comunicação, nas estratégias, nas decisões, nos sistemas de análise de processos das nossas empresas, entre outras. Os software são normalmente concebidos para permitir aos os seres humanos realizar tarefas para as quais o cérebro humano não é capaz, tais como: manipulação de grandes quantidades de informação, realização de cálculos complexos, e controlar simultâneamente muitos processos. Este projecto final foi desenvolvido exactamente sobre a disciplina de software. O presente documento mostra como uma empresa multinacional desenvolve internamente um novo software modular. Algumas técnicas serão investigadas e aplicadas a um problema real existente na empresa Robert Bosch-Bélgica, pertencente ao sector automóvel e principal responsável mundial pela produção de limpa pará-vidros. Aqui se encontrará uma sugestão para uma metodologia do ciclo de vida de um software e será explicado passo a passo todos os aspectos deste processo, desde a criação até ao desenvolvimento desta nova ferramenta de cálculo de apoio à decisão para o design. Esta metodologia foi aplicada à empresa permitindo assim a criação de um manual para o software de simulação chamado “GWB”. Mais precisamente, este projecto descreve a fase de testes, definido como a validação. Esta fase inclui um planeamento e execução de testes do software. Estes resultados foram analisados e comparados com as medições reais. Com base em conhecimentos anteriores, foi conseguido melhorar a precisão do software quer em parâmetros de produção quer em parâmetros de comportamento real dos limpa pará-brisas. Com a criação do manual e do melhoramento do software foram alcançados os dois objectivos principais envolvidos neste estágio. Este trabalho contribuiu significativamente para o desenvolvimento do software de simulação da Robert Bosch, no entanto, é sugerido um conjunto de acções futuras. Estas têm como objectivo ajudar no desenvolvimento do “GWB” para uma implementação adequada no processo de produção de limpa pará-brisas. ABSTRACT: In the last decades the evolution of software industry has reached an extreme importance in our personal daily life and also in the companies behavior. The existing sets of tools represent a vital role in our company’s communications, strategies, decisions supports, systems and process analysis, among others. Software is typically designed to enable humans to perform tasks which the human brain is not well capable, such as: handling large amounts of information, performing complex calculations, and controlling many simultaneous processes. This final project was developed based under the subject software. The present document shows how a multinational enterprise develops internally a new modulate software. Some techniques will be investigated and applied to a real life problem existing in the successful Robert Bosch-Belgium company at the automobile industry world responsible for the production of wiper blades. Here you will find a suggestion of a software life cycle methodology and an explanation step by step of all the aspects of this process from the creation to the development of a new calculation tool for design decision support. This methodology was applied to the company thus enabling to create a handbook for the simulation software called “GWB”. More precisely this project describes the testing phase, defined as validation. This phase contains the planning and execution of software tests. These results were analyzed and compared with real measurements. Based on previous knowledge, was able to improve the accuracy of the software either in production parameters or on parameters of actual behavior. With the creation of the manual and the software improvement two main objectives involved in this internship were accomplished. This work contributed significantly to the development of the Robert Bosch simulation software. However, it is suggested several future actions. To assist in the development of the “GWB” tool for a proper implementation in the wiper blade production process.

The cab assembly line in Oskarshamn is one of the world's most high tech production unit. With close to 300 robots the cab is assembled with merely programmed robots and no input from humans. Scania CV AB is a world leading manufacturer of trucks with high influence on the market globally. Even though robots do most of the work, there have been human brains behind the robot execution, and there is constant work ongoing to further increase efficiency and cycle times to meet the increasing global demand for logistics services. The robots are mainly programmed offline, using the ABB software Robotstudio, which basically creates a digital representation of the actual control system without interfering with the production. Testing upgraded programs as well as simulating them offline before implementation is an essential daily operation to make the production meet the demands. This thesis is divided into two objectives, one theoretical and one practical. The theoretical part focuses on the software, and consists of a critical analysis of a series of different software solutions for programming robots offline, as well as a look into how the offline programming processes work today in-house. The practical objective is to further improve the quality of the simulations conducted through creating tools to answer the calls from functional packages for the different processing equipment used on site. These functional packages lets you perform spot welding, gluing or gripping for instance, and as it is an outsourced service a lot of the coding is encrypted which prevents simulations being conducted with the pre-programmed routines, it makes the simulations crash. This report presents conclusions made regarding the use of offline programming equipment both in the regards of daily operations as well as long term strategies with digital twins and digitization. It also proves that the functional packages still can be simulated even though the code has been manipulated and encrypted at one point. It holds the complete ways of how to, from a 3D CAD model, create mechanisms, synchronize external axes, and creating smart components to answer digital inputs and presenting digital outputs to the system to have a fully functional simulation run.

The field of numerically controlled (NC) machining has long been interested with predicting and measuring the errors in machining. Creating a simulation of NC machining is one way of achieving this. This thesis presents one such implementation of an NC simulation. It also runs a number of numerical and physical tests to verify the simulation?s correctness. The numerical tests show that the simulator work correctly as well as providing guide lines for appropriate simulation parameters. The physical tests show that the results of the simulation match the results of real NC machines. It is hoped that this thesis can provide a guide for the creation of machining simulators and their verification.

Updates to the ATLAS fast simulation software are presented which improve the flexibility of its calorimeter and reconstructor objects allowing the easy implementation of new and unforeseen detector effects. Both hot and dead cell types are studied as initial examples and can be seen to be working as expected. A suite of jet finding algorithms known as ‘FastJet’ is introduced and linked into the ATLAS code framework to help unify the description of jets between fast and full simulations as well as in the reconstruction of data. Preparations for an early-data supersymmetry search in the 0-lepton, jets and ETmiss T channel are presented which, in the absence of a study of the background systematics, show the validity of the channel in detecting the ‘SU3’ mSUGRA benchmark point above the combined standard model background. The most up-to-date publication observes good agreement between the simulated SM background and data up to values of ETmiss ~100 GeV and Meff ~1500 GeV showing a good understanding of both detector and physics simulation and that the real ATLAS detector is performing as expected. The first ATLAS inclusive measurement of charged particle multiplicities in events with nch ≥ 1 within the kinematic range pT > 500 GeV and |η| < 2.5 is discussed. With a measured charged particle multiplicity per event and per unit of pseudorapidity at η = 0 of 1.333 ± 0.003(stat.) ±0.040(syst.) being some 5-15% higher than predicted, clear differences are evident between the Monte Carlo predictions and what is observed in the data. Contributions from the author including trigger efficiency studies, a ‘Rivet’ analysis routine, a simple simulation of the MBTS as well as the creation of a fast trigger simulation of the MBTS triggers L1_MBTS_1, L1_MBTS_2 and L1_MBTS_1_1 are detailed.

Control software plays an important role in industrial automation. Several domainspecific languages for control software implementation were designed and accepted in industry. Structured Text (ST)[1] is one of these languages. It is standardized by IEC 61131-3 standard and designed for programmable logic controllers. In this thesis two implementations of control software were developed: Java implementation as a reference model, and ST implementation as a test scenario for ST to C compiler. The functionality of both implementations was compared using the simulation model. It was concluded that resulting ST control software provides the same functionality as its reference model.

Simulation software is being increasingly used in various domains for system analysis and/or behavior prediction. Traditionally, researchers and field experts need to have access to the computers that host the simulation software to do simulation experiments. With recent advances in cloud computing and Software as a Service (SaaS), a new paradigm is emerging where simulation software is used as services that are composed with others and dynamically influence each other for service-oriented simulation experiment on the Internet.
The new service-oriented paradigm brings new research challenges in composing multiple simulation services in a meaningful and correct way for simulation experiments. To systematically support simulation software as a service (SimSaaS) and service-oriented simulation experiment, we propose a layered framework that includes five layers: an infrastructure layer, a simulation execution engine layer, a simulation service layer, a simulation experiment layer and finally a graphical user interface layer. Within this layered framework, we provide a specification for both simulation experiment and the involved individual simulation services. Such a formal specification is useful in order to support systematic compositions of simulation services as well as automatic deployment of composed services for carrying out simulation experiments. Built on this specification, we identify the issue of mismatch of time granularity and event granularity in composing simulation services at the pragmatic level, and develop four types of granularity handling agents to be associated with the couplings between services. The ultimate goal is to achieve standard and automated approaches for simulation service composition in the emerging service-oriented computing environment. Finally, to achieve more efficient service-oriented simulation, we develop a profile-based partitioning method that exploits a system’s dynamic behavior and uses it as a profile to guide the spatial partitioning for more efficient parallel simulation. We develop the work in this dissertation within the application context of wildfire spread simulation, and demonstrate the effectiveness of our work based on this application.

In this research we present one of the first actual applications of Multi Agent-Based Simulation (MABS) to the field of software process simulation modelling (SPSM). Although a few previous applications were attempted, we explain in our literature review how these failed to take full advantage of the agency paradigm. Our research resulted in a model of the software development process that integrates performance, cognition and artefact quality, for which we built a common simulation framework to implement and run MABS and System Dynamics (SD) simulators upon the same integrated models. Although it is not possible to fully verify and validate implementations and models like ours, we used a number of verification and validation techniques to increase our confidence in these. Our work is also quite unique in that it compares MABS to SD in the context of SPSM. Here, we uncovered quite interesting properties of each simulation approach and how MABS, for example, is "risk averse" when compared to SD. In our discussion section we also present a number of lessons learned regarding the two simulation paradigms as well as various shortcomings in the models we adopted and our own.

This thesis has two aims, both related with simulation programs. The first one is to analyze the viability of using Factory I/O as a tool at the University of Gävle for teaching and understanding the PLCs and the ladder programing. The second one is do a 3D model of the robotics laboratory to use it with the KUKASim and after that find a method to transfer code from KUKASim to the actual robots.Factory I/O has been install and use with a Siemens PLC, which was programed in Siemens TIA Portal. The evaluation of the software as a teaching tool has been done according to a supposition of how much time could it take to an average bachelor degree student in automation to create a functional project. In order to determine that, a demo has been done, which consist on a process in where a box enters by a conveyor. There are two ruts for the box to exit, straight or to the left, and the direction is choose by moving a switcher in the PLC. After analyzing finishing the demo, it has been determinate that it could take around 4 hours to complete a functional project.For the KUKASim part, KUKASim was already installed. However, during the development of this project it was updated from 2.2 to 3.0.4 which caused a minor issues; the SketchUp model could not be imported to 2.2 version and by the time that the upgrade was made the 3D environment of the robotic laboratory was already made in KUKASim.On the other hand, the Office Lite software was needed to be installed in order to transfer the code from KUKASim to the real robots, but due to some license issues, the installation was done at the end period of the project. The connection of both software was not possible to make, still, during the time that Office Lite was not available, an alternative method to transfer the code was found. The program files were download from KUKASim and transfer to the robot with WorkVisual.The conclusion of the thesis is that Factory I/O could be used as a learning and teaching tool because is an easy program to work with. All the same, KUKASim is a multifunctional software, which has make it possible to achieve both of the purposes for corresponding part of the project.

The analysis of the reliability of CREO simulate will be done step by step. First of all, the precisionof the simulation has to be measured thus a comparison with simple theoretical computations willbe done. Then, the scope of the capacity of the software will be analyzed and if elements deemednecessary to thermal simulations are missing, back up solutions are to be found. Also, the influenceof the meshing will be studied and measured to ensure that the software guarantee convergence evenin the hand of persons unfamiliar with simulations.In parallel, one will experiment with realistic hardware that could be used to compare reality withthe simulations. Those experiments will be handmade using regular materials from the company.

In recent years, simulation modelling of software processes have has promoted as a tool to understand, study, control, and manage software development processes. Claims have been made that simulation models are useful and effective at gaining insight into software development processes. However, little has been said about the process of developing simulation models for software engineering problems. Simulation modelling is a young discipline in software engineering. Consequently, many number software process simulation modellers are thought to be novices. The simulation modelling process is believed to have had an effect on the quality of a simulation study. Although there is a body of knowledge available in the general simulation literature to guide and educate novices, the software process simulation modelling literature lacks information for novice software process simulation modellers to understand and adopt a simulation modelling process. This thesis aims to develop a simulation modelling process for novice software process simulation modellers. This thesis reports how the development and evaluation of a simulation modelling process for novice software process simulation modellers. The rapid simulation modelling process (RSMP) is based on an empirical study of the contexts and practices of expert simulation modellers in SPSM and Operational Research (OR). The RSMP is intended to be independent of a particular simulation technique (i. e. system dynamics or discrete event simulation) and guides novice software process simulation modellers through a set of steps that should be undertaken during a simulation study; the RSMP emphasises heavy client contact and provides guidelines for model documentation. The RSMP has been evaluated through controlled experiments with novice software process simulation modellers using system dynamics (SD) modelling. In the future, it will be further evaluated with software process simulation modellers using discrete event simulation. The RSMP has also been evaluated with a panel of expert software process simulation modellers. The main contribution of this study lies in providing novice software process simulation modellers with a simulation modelling process, which embodies real world simulation practice and is intended to be independent of a particular simulation technique.

Over the years, medical imaging modalities have evolved drastically. Accordingly, the need for conveying the basic imaging knowledge to future specialists and other trainees becomes even more crucial for devoted educators. Understanding the concepts behind each imaging modality requires a plethora of advanced physics, mathematics, mechanics and medical background. Absorbing all of this background information is a daunting task for any beginner. This thesis focuses on developing an ultrasound imaging education tutorial with the goal of easing the process of learning the principles of ultrasound. This tutorial will utilize three diverse approaches including software and hardware applications. By performing these methodologies from different perspectives, not only will the efficiency of the training be enhanced, but also the trainee?s understanding of crucial concepts will be reinforced through repetitive demonstration. The first goal of this thesis was developing an online medical imaging simulation system and deploying it on the website of the University of Miami. In order to construct an easy, understandable, and interactive environment without deteriorating the important aspects of the ultrasound principles, interactive flash animations (developed by Macromedia Director MX) were used to present concepts via graphic-oriented simulations. The second goal was developing a stand-alone MATLAB program, intended to manipulate the intensity of the pixels in the image in order to simulate how ultrasound images are derived. Additionally, a GUI (graphic user interface) was employed to maximize the accessibility of the program and provide easily adjustable parameters. The GUI window enables trainees to see the changes in outcomes by altering different parameters of the simulation. The third goal of this thesis was to incorporating an actual ultrasound demonstration into the tutorial. This was achieved by using a real ultrasound transducer with a pulse/receiver so that trainees could observe actual ultrasound phenomena, and view the results using an oscilloscope. By manually adjusting the panels on the pulse/ receiver console, basic A-mode ultrasound experiments can be performed with ease. By combining software and hardware simulations, the ultrasound education package presented in this thesis will help trainees more efficiently absorb the various concepts behind ultrasound.

Increased competition in many industries has resulted in a greater emphasis on developing and using advanced manufacturing systems to improve productivity and reduce costs. The complexity and dynamic behaviour of such systems, make simulation modelling one of the most popular methods to facilitate the design and assess operating strategies of these systems. The growing need for the use of simulation is reflected by a growth in the number of simulation languages and data-driven simulators in the software market. This thesis investigates which characteristics typical manufacturing simulators possess, and how the user requirements can be better fulfilled. For the purpose of software evaluation, a case study has been carried out on a real manufacturing system. Several simulation models of an automated system for electrostatic powder coating have been developed using different simulators. In addition to the evaluation of these simulators, a comprehensive evaluation framework has been developed to facilitate selection of simulation software for modelling manufacturing systems. Different hierarchies of evaluation criteria have been established for different software purposes. In particular, the criteria that have to be satisfied for users in education differ from those for users in industry. A survey has also been conducted involving a number of users of software for manufacturing simulation. The purpose of the survey was to investigate users' opinions about simulation software, and the features that they desire to be incorporated in simulation software. A methodology for simulation software selection is also derived. It consists of guidelines related to the actions to be taken and factors to be considered during the evaluation and selection of simulation software. On the basis of all the findings, proposals on how manufacturing simulators can be improved are made, both for use in education and in industry. These software improvements should result in a reduction in the amount of time and effort needed for simulation model development, and therefore make simulation more beneficial.

This work presents the advancements in the development of simulation models of spacecraft components as part of a testbench for verification of onboard flight software. The satellite and its mission are briefly described as to give an idea of the conditions where the simulation has to run. The simulation environment, SimTG, is also introduced and a description of the developed models is presented. The models required interaction between different simulation environments, real hardware and simulated hardware, and also some data processing was necessary in order to filter undesired information. Finally, the performance of the models was tested and verified and a sensible improvement of the state of the testbench on the simulation side was achieved, although a considerable amount of work still lies ahead before a complete onboard software verification tool is ready.

The car is the most common vehicle in the world. Millions of cars are produced annually. In order for each car to find its buyer, car companies are forced to constantly improve the design of the car. Modern models are emerging, new car systems are being developed and implemented. All this is accompanied by a huge flow of information, in which it is easy to get lost. This master’s work is devoted to the trace analysis and connection of two different files. The paper proposes a developed algorithm of trace analysis for some functions of the vehicle in the C++ programming language. The files that we use to trace analysis relate to the model and the final result of its simulation.EATOP is a tool with which a model based on the EAST-ADL language was developed. Adapt is an event simulator with which our model of automotive functionality was simulated. The purpose of the study is to identify possible ways to meet timing requirements. The work is carried out in collaboration with Volvo Group Truck Technology. This company provided the LogFile, which presents results of the simulation, and model. We get an analysis of performance, one of the ways to trace data and timing. The results of our implementation are presented and discussed.

The method was developed specifically to aid the software development needed for the hierarchy of computers that are present in an FMS. The method was developed by modeling an existing FMS. The models developed of the existing FMS are described in detail to provide an example of how to model other FMSs. The basic building blocks needed for designing other FMSs with this modeling method are provided.
The models were written in the SIMAN simulation language. SIMAN was found to be an easy language to use for the hierarchical modeling of FMSs.M.S.

The literature indicates that usability studies, commonly used in industry, are rarely conducted with educational software and children. The problem addressed in this study examined the issue of educational software usability studies with children. The researcher conducted an experimental, randomized control-group posttest study investigating the redesign of the human-computer interface of educational simulation software.
The study employed a testing instrument designed by the researcher. The validation of the instrument is contained within this study. Along with the test instrument embedded counters were used to collect data for this study. The data were analyzed using descriptive statistics and ANOVA.
Results showed that software rewritten with a redesigned human-computer interface was easier for students to use. This was an expected outcome. An item analysis of the test instrument was used to attempt to explain why the new interface was easier for the students.
The human-computer interface was rewritten using human factors guidelines. Results were that menus may be a better interface than sentence direction, if the task is not too difficult. When the difficulty increased, the data yielded evidence that menus may not be any more effective than sentence directions.
The use of inverse video for giving directions was also examined. The results showed a definite increase in effectiveness when inverse video directions were changed to a menu format. A focus of this study was to determine if usability studies should be conducted on childhood populations. It is the researcher's belief that this is essential for major improvements in educational software.

This report is about the thesis work PyNestGUI which goal was to make a graphical interface to the neuron simulator NEST. The report's first part is about how NEST works well as which graphical interface that where selected. The report then continues go through what a neuron is and how it works superficial. The final section of the report will cover how PyNestGUI is build and how the program works. The problem that the program solves is that it builds a model in NEST with user settings and connects neurons in a similar way as a minicolumn are interconnected. The programs purpose was that it would help the user to change the variables in an easy manner and produce results that can be visualized and save for later analysis. Results that the the program can plot from the simulation is from voltmeters and a spike detector connected all neurons. The program can also display an animation of the simulation so that the user will be able to see when and which neurons spikes and their connections.

Rapportens första del handlar om hur NEST fungerar samt vilket grafiskt gränssnitt som valdes ut. Sedan fortsätter rapporten med att ytligt gå igenom vad en neuron är och hur den fungerar. Sista delen av rapporten går igenom hur PyNestGUI är uppbyggt och hur programmet fungerar. Problemet som programmet löser är att den bygger upp en modell i NEST med användarens inställningar och kopplar ihop neuroner på liknande sätt som en minikolumn är sammankopplad. Programmets syfte var att det skulle hjälpa användaren kunna ändra på variabler på ett lätt sätt samt ge resultat som kan visualiseras och som användaren skulle kunna spara. Resultat som programmet kan visa av simuleringen är voltmätare och spikdetektor på samtliga neuroner. Programmet kan också visa en animation av simuleringen så att användaren ska kunna se när neuroner spikar och vilka dessa neuroner är sammankopplade med.

Bergkvist insjön AB is a sawmill yard which is capable of producing 350,000 cubic meter of timber every year this requires lot of internal resources. Sawmill operations can be classified as unloading, sorting, storage and production of timber. In the company we have trucks arriving at random they have to be unloaded and sent back at the earliest to avoid queuing up of trucks creating a problem for truck owners. The sawmill yard has to operate with two log stackers that does several tasks including transporting the logs from trucks to measurement station where the logs will be sorted into classes and dropped into pockets from pockets to the sorted timber yard where they are stored and finally from there to sawmill for final processing. The main issue that needs to be answered here is the lining up trucks that are waiting to be unload, creating a problem for both sawmill as well as the truck owners and given huge production volume, it is certain that handling of resources is top priority. A key challenge in handling of resources would be unloading of trucks and finding a way to optimize internal resources.To address this problem i have experimented on different ways of using internal resources, i have designed different cases, in case 1 we have both the log stackers working on sawmill and measurement station. The main objective of having this case is to make sawmill and measurement station to work all the time. Then in case 2, i have divided the work between both the log stackers, one log stacker will be working on sawmill and pocket_control and second log stacker will be working on measurement station and truck. Then in case 3 we have only one log stacker working on all the agents, this case was designed to reduce cost of production, as the experiment cannot be done in real-time due to operational cost, for this purpose simulation is used, preliminary investigation into simulation results suggested that case 2 is the best option has it reduced waiting time of trucks considerably when compared with other cases and it showed 50% increase in optimizing internal resources.

Assim, a descrição de como foi o desempenho de cada agente desenvolvido também é apresentado.
The financial market has presented significant growth in the automation of decisions and execution of strategies that can achieve good returns from investments. Consequently, the need for an increasingly robust and reliable environment, allowing to analyze different investment strategies, has increased. Based on this need, this work presents A Multi-Agent System Framework For Automated Stock Exchange Simulation (FrAMEX), which allows the creation of different simulators for the financial market based on the paradigm of software agents. Intraday and interday simulators created from FrAMEx are presented in the document. Besides the analysis of different investment strategies used in such environments and executed by agents run from investors. Since these agents achieved good performances in their executions, they participated in two versions of the MASSES competition. Thus, the description of the performance of each agent developed is also presented.

Software based routing simulators suffer from large simulation host requirements and are prone to slow downs because of resource limitations, as well as context switching due to user space to kernel space requests. Furthermore, hardware based simulations do not scale with the passing of time as their available resources are set at the time of manufacture. This research aims to provide a software based, scalable solution to network simulation. It aims to achieve this by a Linux kernel-based solution, through insertion of a custom kernel module. This will reduce the number of context switches by eliminating the user space context requirement, and serve to be highly compatible with any host that can run the Linux kernel. Through careful consideration in data structure choice and software component design, this routing simulator achieved results of over 7 Gbps of throughput over multiple simulated node hops on consumer hardware. Alongside this throughput, this routing simulator also brings to light scalability and the ability to instantiate and simulate networks in excess of 1 million routing nodes within 1 GB of system memory

xvii, 289 p. : ill. (some col.) A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number.This thesis provides a design and development of a software architecture and programming framework that enables domain-oriented scientific investigations to be more easily developed and productively applied. The key research concept is the representation and automation of scientific studies by capturing common methods for experimentation, analysis and evaluation used in simulation science. Such methods include parameter studies, optimization, uncertainty analysis, and sensitivity analysis. While the framework provides a generic way to conduct investigation on an arbitrary simulation, its intended use is to be extended to develop a domain computational environment. The framework hides the access to distributed system resources and the multithreaded execution. A prototype of such a framework called ODESSI (Open Domain-oriented Environment for Simulation-based Scientific Investigation, pronounced odyssey) is developed and evaluated on realistic problems in human neuroscience and computational chemistry domains. ODESSI was inspired by our domain problems encountered in the computational modeling of human head electromagnetic for conductivity analysis and source localization. In this thesis we provide tools and methods to solve state of the art problems in head modeling. In particular, we developed an efficient and robust HPC solver for the forward problem and a generic robust HPC solver for bEIT (bounded Electrical Impedance Tomography) inverse problem to estimate the head tissue conductivities. Also we formulated a method to include skull inhomogeneity and other skull variation in the head model based on information obtained from experimental studies. ODESSI as a framework is used to demonstrate the research ideas in this neuroscience domain and the domain investigations results are discussed in this thesis. ODESSI supports both the processing of investigation activities as well as manage its evolving record of information, results, and provenance.

Mestrado em Engenharia e Gestão IndustrialCom a globalização e o aumento de competitividade as empresas viram se forçadas a encontrar novas formas de optimização e de estar constantemente à acrescentar mais valor aos seus produtos. Como resultado, existe uma mudança progressiva para uma perspectiva externa com ênfase na concepção e implementação de novas parcerias estratégicas, que são geralmente nomeadas com o título de gestão da cadeia de abastecimento. No entanto, apesar do florescimento de várias soluções informáticas neste contexto, ainda há vários obstáculos evidentes a superar. Principalmente devido à maior complexidade dos problemas gerados numa rede logística onde existem conflitos resultantes de objectivos locais versus estratégias de integração. A simulação que conta já com um vasto histórico em aplicações industriais poderá revelar-se numa importante mais-valia neste novo âmbito. Esta ferramenta é usada para efectuar análises, estudos, optimizar projectos e identificar novas oportunidades. As empresas actualmente produzem numa rede complexa na maioria das vezes estão presentes em diferentes países, com múltiplas oportunidades de mercado. Normalmente existe a necessidade de produzirem componentes sofisticados que raramente são criados num único local. Isso representa um desafio extra para a plena utilização das ferramentas de simulação. Este trabalho tenta validar a ideia de que há um potencial inexplorado no uso e desenvolvimento de software de simulação. Novas aplicações tecnológicas estão a ser formuladas que tiram partido destes novos parâmetros e dão resposta a um superior número de critérios de eficiência e de produtividade nas empresas. Em conjunto procuram dar uma resposta a estes problemas, bem como integrar plenamente e com sucesso as empresas em novas formas de negócio como a gestão cadeia de abastecimento.
The increased level of competitiveness in all industrial sectors, exacerbated in the last years by the globalization of the economies. This is pushing enterprises to find new ways to optimize their processes, and in particular to pursue new forms of collaboration and partnership with their direct logistics counterparts. As a result, at a company level there is a progressive shift towards an external perspective with the design and implementation of new management strategies, which are generally named with the term of supply chain management (SCM). However, despite the flourish of several IT solutions in this context, there are still evident hurdles to overcome. Mainly due to the major complexity of the problems to be tackled in a logistics network and to the conflicts resulting from local objectives versus network strategies. Simulation has now a solid background in manufacturing applications. This tool is used to perform analyses, studies, optimize designs and also identify problems. Companies now produce in a complex environment and most of the times they are present in different countries with different market opportunities, manufacturing intricate products that are seldom created in a single location. This poses an extra challenge for the full use of simulation. This work tries to validate the idea that there is an untapped potential in simulation software. And new forms of distributes simulation techniques are growing to give an answer to these problems as well as fully integrate companies successfully into new ways of business like supply chain management.

L'étude d'un système à l'aide de simulations informatiques à événements discrets implique plusieurs activités: spéci cation du modèle conceptuel, description de l'architecture logicielle du modèle, développement des logiciels, scénarisation de la simulation, instrumentation, plani cation d'expérimentation, con guration des ressources de calcul, exécution, post-traitement et analyse, validation et de véri cation (V&V). De nombreux éléments logiciels sont requis pour remplir toutes ces activités. Toutefois, il est fréquent de créer un nouveau simulateur à partir de rien quand on commence une étude à l'aide de simulation. Dans ce cas il est nécessaire de développer de multiples outils prenant en charge les activités de la simulation. Cette thèse aborde le dé de la création de nouveaux simulateurs tout en réutilisant des modèles et des outils provenant d'autres simulateurs. En e et, la réutilisation de logiciel augmente la abilité, est moins sujette aux erreurs, permet une meilleure utilisation des expertises complémentaires, améliore la conformité aux normes, et accélère le développement. La réutilisation de logiciels peut être appliquée à toutes les activités de la simulation. Plusieurs problèmes doivent être résolus pour tirer pleinement pro t de la réutilisation. Dans cette thèse, nous abordons trois questions principales: Tout d'abord, nous étudions les solutions pratiques de réutilisation permettant de combiner un ensemble choisi d'éléments logiciels utiles pour la modélisation et la simulation, en incluant aussi bien les modèles, les moteurs de simulation, les algorithmes et les outils; Deuxièmement, nous nous concentrons sur les questions liées à l'instrumentation; Troisièmement, nous étudions le problème de l'intégration d'éléments logiciels provenant d'autres simulateurs dans un nouveau simulateur. Pour atteindre ces objectifs, nous étudions des techniques avancées de du génie logiciel, tels que le génie logiciel à base de composants (CBSE) et la programmation orientée aspect, sur lesquels nous construisons une solution originale pour la modélisation et la simulation à l'aide de multiples couches réutilisables. Nous avons développé un prototype d'architecture logicielle qui prouve la faisabilité de cette solution.

Recently the community started looking into Hardware/Software (HW/SW) co-designed processors as potential solutions to move towards the less power consuming and the less complex designs. Unlike other solutions, they reduce the power and the complexity doing so called dynamic binary translation and optimization from a guest ISA to an internal host custom ISA. This thesis tries to answer the question on how to simulate this kind of architectures.
For any kind of processor's architecture, the simulation is the common practice, because it is impossible to build several versions of hardware in order to try all alternatives. The simulation of HW/SW co-designed processors has a big issue in comparison with the simulation of traditional HW-only architectures. First of all, open source tools do not exist. Therefore researches many times assume that the software layer overhead, which is in charge for dynamic binary translation and optimization, is constant or ignored. In this thesis we show that such an assumption is not valid and that can lead to very inaccurate results. Therefore including the software layer in the simulation is a must.
On the other side, the simulation is very slow in comparison to native execution, so the community spent a big effort on delivering accurate results in a reasonable amount of time. Therefore it is the common practice for HW-only processors that only parts of application stream, which are called samples, are simulated. Samples usually correspond to different phases in the application stream and usually they are no longer than a few million of instructions. In order to archive accurate starting state of each sample, microarchitectural structures are warmed-up for a few million instructions prior to samples instructions. Unfortunately, such a methodology cannot be directly applied for HW/SW co-designed processors.
The warm-up for HW/SW co-designed processors needs to be 3-4 orders of magnitude longer than the warm-up needed for traditional HW-only processor, because the warm-up of software layer needs to be longer than the warm-up of hardware structures. To overcome such a problem, in this thesis we propose a novel warm-up technique specialized for HW/SW co-designed processors. Our solution reduces the simulation time by at least 65X with an average error of just 0.75\%. Such a trend is visible for different software and hardware configurations.
The process used to determine simulation samples cannot be applied to HW/SW co-designed processors as well, because due to the software layer, samples show more dissimilarities than in the case of HW-only processors. Therefore we propose a novel algorithm that needs 3X less number of samples to achieve similar error like the state of the art algorithms. Again, such a trend is visible for different software and hardware configurations.Els processadors co-dissenyats Hardware/Software (HW/SW co-designed processors) han estat proposats per l'acadèmia i la indústria com a solucions potencials per a fabricar processadors menys complexos i que consumeixen menys energia. A diferència d'altres alternatives, aquest tipus de processadors redueixen la complexitat i el consum d'energia aplicant traducció y optimització dinàmica de binaris des d'un repertori d'instruccions (instruction set architecture) extern cap a un repertori d'instruccions intern adaptat. Aquesta tesi intenta resoldre els reptes relacionats a la simulació d'aquest tipus d'arquitectures. La simulació és un procés comú en el disseny i desenvolupament de processadors ja que permet explorar diverses alternatives sense haver de fabricar el hardware per a cadascuna d'elles. La simulació de processadors co-dissenyats Hardware/Software és un procés més complex que la simulació de processadores tradicionals, purament hardware. Per exemple, no existeixen eines de simulació disponibles per a la comunitat. Per tant, els investigadors acostumen a assumir que la capa de software, que s'encarrega de la traducció i optimització de les aplicacions, no té un pes específic i, per tant, uns costos computacionals baixos o constants en el millor dels casos. En aquesta tesis demostrem que aquestes premisses són incorrectes i que els resultats amb aquestes acostumen a ser molt imprecisos. Una primera conclusió d'aquesta tesi doncs és que la simulació de la capa software és totalment necessària. A més a més, degut a que els processos de simulació són lents, s'han proposat tècniques de simulació que intenten obtenir resultats precisos en el menor temps possible. Una pràctica habitual és la simulació només de parts de les aplicacions, anomenades mostres, en el disseny de processadors convencionals, purament hardware. Aquestes mostres corresponen a diferents fases de les aplicacions i acostumen a ser de pocs milions d'instruccions. Per tal d'aconseguir un estat microarquitectònic acurat per a cadascuna de les mostres, s'acostumen a estressar aquestes estructures microarquitectòniques del simulador abans de començar a extreure resultats, procés anomenat "escalfament" (warm-up). Desafortunadament, aquesta metodologia no pot ser aplicada a processadors co-dissenyats Hardware/Software. L'"escalfament" de les estructures internes del simulador en el disseny de processadores co-dissenyats Hardware/Software són 3-4 ordres de magnitud més gran que el mateix procés d' "escalfament" en simulacions de processadors convencionals, ja que en els primers cal "escalfar" també les estructures i l'estat de la capa software. En aquesta tesi proposem tècniques de simulació basades en l' "escalfament" de les estructures que redueixen el temps de simulació en 65X amb un error mig del 0,75%. Aquests resultats són extrapolables a diferents configuracions del hardware i de la capa software. Finalment, les tècniques convencionals de selecció de mostres d'aplicacions a simular no són aplicables tampoc a la simulació de processadors co-dissenyats Hardware/Software degut a que les mostres es comporten de manera molt diferent quan es té en compte la capa software. En aquesta tesi, proposem un nou algorisme que redueix 3X el nombre de mostres a simular comparat amb els algorismes tradicionals per a processadors convencionals per a obtenir un error similar. Aquests resultats també són extrapolables a diferents configuracions de hardware i de software. En conclusió, en aquesta tesi es respon al repte de com simular processadors co-dissenyats Hardware/Software, que són una alternativa al disseny tradicional de processadors. Hem demostrat que cal simular la capa software i s'han proposat noves tècniques i algorismes eficients d' "escalfament" i selecció de mostres que són tolerants a diferents configuracions

There is considerable interest within the construction industry to develop models that are able describe the whole life-cycle of a building in an electronic form. Such models would allow for the sharing of building information across the wide range of industry disciplines and lead to efficiencies in the design and construction of buildings. This thesis examines the technologies available and specifically within the context of fire engineering.
Database methods are used to create a repository of fire growth information which can be accessed through web pages or client applications. The IFC Model has emerged as an internationally agreed building model and this thesis investigates its applicability to fire engineering. A suite of software applications have been developed that interpret IFC documents in a form that can be imported into fire simulation models. The thesis discusses the limitations of the current IFC model for use by fire engineers, the challenges in developing IFC interpretation software that can be successfully integrated with the range and complexity of fire simulation software and suggests where future work should be directed to overcome these concerns.

The U.S. military is the largest single user of simulation in the world, and our visual simulations can be software intensive systems with a lifespan of many years. Managers of these simulations need tools to help them make better decisions at the architectural level. Currently, no such quantitative models with supporting metrics exist for this purpose. There are properties that are held as positive characteristics in visual simulation architectures. Visual simulation architectures can be distinguished from one another based on three characteristics: (1) openness, as defined by the use of standards, licensing, and support of innovation; (2) reuse, as defined by the potential of being used in subsequent projects; and (3) agility, as defined by the ease with which software can be integrated, reconfigured, or repurposed. In this research, we propose quantifiable models to measure openness, reuse, and agility, and claim that the models adequately distinguish visual simulation frameworks from one another. Furthermore, we claim that these models can enhance military acquisition decisions. The results show that application of the metrics offers a level of granularity that is useful in identifying key differences in simulation frameworks that could have profound downstream implications.
