Texto completoBusiness Processes (BP) can be seen as a collection of activities executed and coordinated in order to produce a specific result and to meet the needs of a customer (internal and/or external). Business process management (BPM) is a very active research area, its objective is to provide a comprehensive and insightful analysis of the product flow and to identify inefficiencies and potential improvement areas in the process to achieve better decision making and results. Although we can find several Business Process Improvement (BPI) methods in the literature, organizations are still facing some difficulties to apply these methods effectively. These difficulties can be justified by the fact that the existing BPI methods do not fi twith all the recent requirements of the organizations and the progress that the world has achieved, in the past few years, in several domains such as Artificial Intelligence, Data Analytics techniques, Machine Learning, Process Mining, and Event (Stream) Processing, etc. Besides, with this new digitized era and the rise of several new technologies such as Big Data, Internet of things, Cloud computing, etc, organizations are faced with many factors and challenges that generate real changes in the traditional BPM. Among these challenges, we have the huge amount of data and event data that are continuously gathered within the organization. These data represent a real engine of growth for organizations, and must be adequately exploited to extract high added value that can assist the organization in its decision making process. Furthermore, enterprises are looking for advanced technologies that optimize time and resources and increase agility, productivity and most importantly, proactivity. However, traditional BPM systems present different limits, as they do not facilitate the use of knowledge extracted from this data, by business processes, because they do not benefit from statistical functionalities and data analysis and manipulation techniques in real time.The interdisciplinary nature of BPM is a key factor that fosters opportunities for improvement in this domain. The objective of this thesis work is to propose new approaches for augmenting business processes, by relying mainly on data analysis, machine learning algorithms, and complex event processing, to exploit the data generated by business process execution (event data, event logs) and find ways to improve these processes from different perspectives such as instances scheduling and event management in an IoT environment

Texto completoI dagsläget används Virtual Design and Construction (VDC) mer och mer inom byggprojektering såväl som inom byggproduktion som ett effektiviserande arbetssätt för att förbättra kommunikation och minska byggnadsfel. VDC är under ständig utveckling, men vad kommer efter denna? Förstärkt verklighet (AR, eng. Augmented Reality) används i dagsläget inte i byggproduktion i Sverige men ses som nästa steg i ledet av integrering av verklighet och digital information. Med hjälp av denna teknik kan projektering bli verklighet innan det är byggt. Syftet med denna studie har varit att inventera existerande AR-teknik, dess brister samt att kartlägga möjliga användningsområden inom byggproduktion. VDC har även undersökts för att identifiera denna tekniks svagheter och en bedömning av hur dessa kan avhjälpas och VDC förbättras har gjorts. Utifrån detta har arbetet utförts utifrån följande huvudfrågeställning; Hur kan AR-teknik implementeras i byggbranschen och hur kan den integreras med VDC för att uppnå en effektivisering i byggproduktionen? Teoribakgrunden bygger på en litteraturstudie där information om AR-teknik från tekniska rapporter inhämtats. En studie av tekniken bakom Augmented Reality och dess möjliga tillämpningsområden inom byggproduktion har gjorts, samtidigt som framtida möjligheter och pågående forskning har beskrivits. VDC har endast undersökts flyktigt i litteraturstudien. Intervjuer har genomförts med produktionspersonal och sakkunniga inom VDC och AR för att erhålla underlag för en nulägesanalys. Utifrån intervjuerna har nytta och brister med VDC-tekniken kunnat utrönas, samtidigt som önskemål på AR-teknikens framtida tillämpning har kunnat kartläggas. Resultatet av litteraturstudien är att en positioneringsteknik som är noggrannare och mer robust än de som finns idag måste utvecklas för att AR-tekniken ska fungera i syftet. Det finns ett flertal fördelaktiga tillämpningsområden för AR i byggproduktion förutsatt att ovanstående problem övervinns. VDC i produktion innebär stora fördelar i form av ekonomiska och tidsmässiga besparingar. Det främjar kommunikationen mellan projektering och produktion. AR kommer att vara lättare att använda i marknadsföringssyfte och i tidiga skeden än i produktion. Vad gäller VDC behöver mer fokus läggas på att implementera tekniken till den stora massan istället för att utveckla tekniken ytterligare i en liten expertgrupp. För att AR-tekniken ska kunna implementeras i byggbranschen bör VDC-tekniken och dess stöd först utvecklas fullt ut mot produktion innan ytterligare en teknik introduceras då denna inte kommer att åtgärda de brister med VDC som finns idag.

Texto completoCloud storage, communication platforms with interactive functions, virtual models that are merged with physical surroundings, computer simulations, life cycle perspective. This is what is being discussed in the corridors of the BIM-world. But if this is the future: why is the implementation so slow, and what exactly is to be implemented? The process of handling and understanding what BIM is has become too complex, and in this report we want to find solutions for making the way of working intelligible and useful for a wider audience. In collaboration with Vianova Systems, we have investigated what the use of BIM looks like today and what improvements are needed for a wider future implementation in the AEC industry. Our investigations show that almost 80 % believe that work which utilizes a digital model would be more effective: at the same time the insecurity concerning software and uncertainties regarding the implementation of the work methodologies are limiting factors. As a solution for this a user interface for project management and communication has been developed. These investigations have been carried out with the aid of a questionnaire and interviews and compiled into two parts: partly this report, as well as an end product of visionairy nature called ”7 visions for the future of BIM”.

Texto completoNumera blir BIM och realtidsdata ett centralt ämne för AECO (Architecture, Engineering, Construction and Operations) industrin, de representerar nya kraftfulla verktyg för design och hantering av anläggningar.Byggnadsövervakning och realtidsdata kan vara en lösning på många viktiga utmaningar som energieffektivitet, inomhusklimatkvalitet och kostnadshantering. Även om det är tydligt är betydelsen av data för en korrekt användning av BIM-teknik och dess potential i litteraturen inte så vanliga exempel på fullständiga arbetsflöden för en fullständig hantering av data från inmatningsfasen till den utgående.Studiens omfattning är att utforma ett protokoll för inmatning, hantering och export av realtidsdata med Revit och Dynamo där kunderna har en central roll under inmatningsfasen och ett dedikerat läge för datavisning inklusive en stationär version och en förstärkt verklighet en för en mer uppslukande upplevelse.För att visa projektets verkliga potential har protokollet använts för beräkning av termiska komfortparametrar för ”Teaching House” beläget på KTH campus. Alla data som matats in från eleverna i ett formulär online, via QR-kod, har införts i Dynamo för att beräkna önskade parametervärden som successivt lagras i en databas för vidare analys, allt automatiskt.

In urban city, people’s daily life is around large-scale buildings like train stations, museums or department stores. Their indoor circulations are always complicated, and people are not familiar with those emergency evacuation route. Traditionally, emergency exit signs use an arrow to lead people to the emergency exit. If there is an emergency happening, occupants may be nervous, resulting in their misjudging of the exit position. Therefore, the administration of the building needs to assign a lot of staffs to help occupants evacuate. This research developed a BIM-based augmented reality evacuation system to ensure effective evacuation and economize workforce used in an emergency evacuation. First, the system builds a virtual model in users’ smart phone based on information obtained from the BIM model of the building where the emergency is happening. Then, the system uses iBeacons for indoor positioning and calculates the safest and shortest path to the emergency exit. Lastly, occupants evacuate along the path shown in augmented reality view on their smart phone. This research only exports necessary coordinate data and uses .txt file to be the exchange format. Hence, it can reduce the exchange file size and hardware requirement between BIM model and evacuation system in smart phone. The exchange format was selected because it can reduce the exchange file size and hardware requirement for the process in this research. This research confirmed that after using weighted centroid localization algorithm based on received signal strength indication, the accuracy of iBeacon positioning is enough to be applied in indoor navigation. Also, by using coordinates exported from the BIM model to create obstacles in the virtual model, the system can find a shortest path around obstacles efficiently. Finally, the path shown in augmented reality view on users’ smart phone leads them to the nearest emergency exit and enables occupants evacuating by assessing their path to follow during the evacuation.

The purpose of fire safety equipment maintenance is to ensure that in emergencies all the necessary equipment is in good working order so that damage can be kept to a minimum. Current inspection procedures follow the regulations outlined in relevant laws, which require access to the relevant documents and diagrams. However, most of these files are in paper format, which causes inconvenience during the inspection process, thereby wasting both time and labor. To solve the above problems and to help inspectors obtain the information they need as efficiently as possible, this study uses the building information model (BIM) to build the components of fire safety equipment while simultaneously inputting data related to the components’ life cycle into the Revit 3D model using the COBie Toolkit. The data are further organized into a cloud database to enable augmented reality processes such as visual simulation and the use of mobile devices in future inspections. This eliminates the limitations of paper-based documents. To effectively clarify the relationships and responsibilities of information exchange, this study utilized the Construction-Operations Building Information Exchange (COBie) developed by the United States Army Corps of Engineers (USACE) to regulate information exchange. IDEF0 was used to analyze information relationships and responsibility distributions. A literature review and interviews with experts were conducted to understand the practical requirements of maintenance inspections on fire safety equipment; this further served as the framework for the information exchange. In terms of system development and case verification, this study used augmented reality technology to present visual simulation of the equipment. By using the augmented reality tool AURASMA (which provides basic information related to the components) and AUGMENT (which provides a 3D model of the system pipeline), the inspectors can instantly access the cloud database to acquire information such as equipment type, location, or maintenance records. Furthermore, mobile devices are used for recording, which enables information to be uploaded to the cloud database immediately. The selected case studies demonstrate that BIM ensures the integrity, accessibility, and efficacy of data, while the augmented reality technology combines data with physical objects to provide information immediately in a visible and convenient manner. The developed model therefore is an effective tool that efficiently meets the requirements of fire safety equipment maintenance inspections.

In order to keep buildings in good condition, MEP facilities must be maintained by regular and emergency failure maintenance. Failure events of facilities often lead to malfunction and even cause safety problems. When failure event occurs, it is required to be resolved by maintenance operations as soon as possible, so that the building function could be restored without too much loss or even damage. When it comes to maintenance operations, it is critical to carry out facility maintenance efficiently. To achieve this target, maintainers are required to acquire sufficient knowledge of facilities and also information about the environment of maintenance operations. So far, there have been studies improving maintenance process with Building Information Modeling (BIM) and relative tools such as COBie spreadsheet. However, researches about spatial analysis for maintenance, which is to obtain environment information, are rare and needed to be improved. This study employs Augmented Reality (AR) and BIM to construct a mechanism for maintenance simulation and on-site spatial analysis. BIM is used to propose a maintenance plan via 3D simulation, and AR is applied to implement on-site spatial analysis. With the on-site analysis mechanism, the content of previous plan can be verified and more details of actual environment can be discovered. With the proposed framework, the information of maintenance can be more complete and meets the needs of actual maintenance operations.
Kesby, Joss Edwin. "The development and experimental validation of a simulation method for the optimisation of diffuser augmented wind turbines". Thesis, 2019. http://hdl.handle.net/1959.13/1398137.
Texto completoThe addition of a diffuser to a small Horizontal Axis Wind Turbine (HAWT) can significantly improve the performance of the wind turbine. It has long been posited that the resultant wind turbine, known as a Diffuser Augmented Wind Turbine (DAWT), can have improved performance over a bare turbine of the same size with the additional benefits of improved noise mitigation and operation in turbulent wind conditions. It has been shown that the performance of the diffuser affects the performance of the wind turbine blades and vice versa, however, previous work in the field of DAWT optimisation has focussed either on optimising blades for a specific diffuser, or optimising a diffuser and adding a standard HAWT for use within it, both of which are not ideal for the optimisation of the complete system. The work presented in this thesis documents the development and implementation of a new simulation methodology, designated the Combined CFD/BEM Method, to predict the starting performance and power output of a DAWT. This new approach allows the diffuser to be optimised in conjunction with the turbine blades, a process that is computationally intensive using existing methods. This new method can rapidly assess the performance of the DAWT, using optimisation processes heretofore too computationally expensive to be practicable. Effective optimisation techniques which require thousands of geometries to be assessed, such as genetic algorithms, can be implemented using the Combined CFD/BEM Method to optimise the geometry of a DAWT. The optimisation process described in this thesis has utilised genetic algorithms to maximise the Annual Energy Production (AEP) of a DAWT located at a typical small wind turbine site. The wind data for the typical site was obtained from the International Electrotechnical Commission’s (IEC) standards for small wind turbines. Using rapid prototyping methods, the two highest performing DAWTs nominated by the Combined CFD/BEM Method, with diffuser radii of 0.203 m and 0.217 m, were constructed and experimentally tested in the large recirculating wind tunnel at the University of Newcastle, Australia. Two HAWTs with blades of the same radii as the diffusers of the two DAWTs were also optimised and constructed for experimental testing to compare to the performance of the DAWTs. The different wind turbine configurations were experimentally tested for starting performance and mechanical power output for wind speeds between 5 m/s and 10 m/s inclusive. The Combined CFD/BEM Method was shown to accurately predict the starting wind speed of the tested geometries, which were all within 11.4% of the experimental results. The combined CFD/BEM Method underpredicted the power output at the lower tested wind speeds and overpredicted at the higher speeds. For the lower wind speeds, the largest underprediction was 26.5% at 5 m/s with the majority of the predicted power outputs within 10% of experimental results. The largest overprediction at the higher wind speeds was 9.3% at 10 m/s. The Combined CFD/BEM Method has also shown that a DAWT can exceed the power output and AEP of a HAWT of the same size although, given the material utilised for rapid prototyping, this could not be fully validated as the printed blades lacked sufficient rigidity for comprehensive testing. It is worth noting that the diffuser geometries assessed for the current work were simple revolved aerofoils, unadorned with vortex generators, gurney flaps, boundary layer control slots or any other devices that have been shown to improve the performance of a diffuser. Given the accuracy of the Combined CFD/BEM method, it could be utilised in future research to optimise a DAWT employing any of these performance-enhancing modifications.

Texto completoA história da construção começa por relatar um tempo em que tudo era construído num processo de tentativa/erro pelos master builders, que se baseavam no conhecimento antigo. O projeto e a edificação surgiam de acordo com as necessidades que se iam figurando. Só mais tarde surge a Arquitetura com o Renascimento e a Engenharia muito perto da Revolução Industrial, como um dos maiores catalisadores no aparecimento de novos materiais e sistemas tecnológicos. A partir desse período, pouco se alterou até á introdução dos computadores como ferramenta essencial de trabalho. A metodologia BIM (Building Information Modeling) veio substituir a metodologia tradicional CAD (Com-puter Aided Design). Apesar disso, existe uma resistência enorme da indústria AEC para que esta mu-dança seja definitiva, como se percebe olhando para o panorama nacional. Consiste na aprendizagem de novos conceitos, renovação dos métodos de trabalho convencionais e ainda um investimento mone-tário acrescido em hardware e software. Resta continuar a trabalhar na otimização desta metodologia e reforçar a sua importância até ao período tão esperado da normalização. A Realidade Virtual (RV), cujo conceito será ampliado para Realidade Virtual continuum (RVC), surge mais recentemente por intermédio dos videojogos, mas rapidamente se percebe que o seu potencial poderá abrir portas a novas indústrias. Trata-se da criação de um produto que apresenta o resultado final antes do mesmo estar concluído na realidade, à semelhança da modelação 3D e software BIM, mas com a particularidade de atribuir, a qualquer componente do modelo, propriedades e comportamentos reais. Para além disso, através do seu hardware é permitido a imersão e a interação com o meio virtual, que acrescentam a sensação de presença, nunca possível até então. Deste modo, são realizadas aplicações (APK – Android Package) em Realidade Aumentada (RA) e em RV, com o modo de visualização pensado apenas para dispositivos móveis (tablets ou smartphones), devido às limitações intrínsecas neste trabalho. Com estas pretende-se demonstrar a aplicabilidade da RVC no contexto do Grupo Shay Murtagh, uma empresa que atua no ramo do betão pré-fabricado. Para sustentar a introdução desta metodologia no grupo, foi elaborado um processo de implementação hipo-tético com questionários remetidos aos colaboradores do setor de projeto e um mapa de processos.
The History of construction begins by speaking of a time when everything was built on a trial and error basis by master builders that based themselves on old knowledge. Projects and buildings would appear in accordance with needs that would make themselves apparent. Only later does Architecture appear, with the Renaissance, and also with Engineering, closer to the Industrial Revolution, as one of the largest catalysts for the appearance of new materials and new technological systems. From that period onwards, little has changed until the introduction of computers as an essential working tool. BIM methodology has replaced the traditional CAD methodology. Despite that, there is an enormous resistance from the AEC industry to making this change definitive, as one can understand by looking at the national panorama. It consists on the learning of new concepts, on the renewal of conventional work-ing methods, and still on an added monetary investment on hardware and software. Works remains to be done on the optimisation of this methodology and on reinforcing its importance, until the expected period of its normalisation. Virtual reality, a concept which will be extended on the current work-s discussion to Virtual Reality Con-tinuum, appears more recently by means of videogames. However, one quickly understands its potential to open doors to new industries. It is about the creation of a product that can present the final result before it is concluded in reality - similarly to 3D modelling and BIM software - but with the particularity of attributing real behaviours to any of the component's elements. Beyond that, through its hardware, it enables immersion and interaction with the virtual medium, which adds a feeling of presence, something previously not possible. In this way, some applications are made (APK - Android Package) in AR and VR - only with mobile visual-isation methods - due to this work's intrinsic limitations. They intend to demonstrate the applicability of VRC in the context of the Shay Murtagh group, a company that operates in the field of pre-fabricated concrete. In order to sustain the introduction of this methodology into the group, an hypothetic imple-mentation process has been developed, with questionnaires being sent to collaborators in the project sector, and a process map.
