Hefnawy, Ahmed. "Lifecycle-based Modeling of Smart City Ecosystem." Thesis, Lyon, 2018. http://www.theses.fr/2018LYSE2014.
Full textSmart city system development, operation and maintenance are very complex tasks and involve numerous stakeholders from different disciplines and domains. In most cases, these systems are at different phases of design, deployment and operation, i.e. at different phases of lifecycle. Hence, lifecycle management concepts are very important to better manage smart city development as a complete ecosystem across different phases of lifecycle. This argument is supported by the findings of our smart city survey, where the information gathered from interviewed stakeholders proves the relevance of a lifecycle approach to address the identified nine concerns; non-alignment to strategic objectives, regulatory failure at different phases, delay in “time to market”, disjointed processes, difficult knowledge sharing and data traceability, inefficient and delayed exchange of data/ information, and inefficient and ineffective use of infrastructure.To address the abovementioned concerns, this thesis proposes the application of lifecycle management concepts in smart cities, which requires the introduction of the time notion to smart city modeling by adding the lifecycle viewpoint as a new dimension to the multi-layered architecture. The proposed smart city lifecycle-based approach consists of two components. First, the three-dimensional model that enables smart city developers to consider three viewpoints: Architecture Layers, Time (Lifecycle Phases), and Domains. Second, the interaction approach that enables integration between lifecycle management systems and IoT platforms. This approach is validated through a use-case of Smart Parking System, proposed as part of the FIFA World Cup™ 2022. The proposed smart parking system is strategically aligned to Smart Qatar objectives and connects all relevant stakeholders across the different lifecycle phases. To ensure semantic interoperability, the smart parking system uses the DATEX II standards for static and dynamic parking related data. Finally, the use-case focuses on the integration between lifecycle related data and IoT data through the interaction between Aras Innovator® lifecycle system (BoM construction, configuration management, etc.) and the O-MI/O-DF IoT Reference Implementation Platform (peer-to-peer publication and discovery of parking-related information in an aggregated form)

Full textWith the construction and development of the smart city, how to construct the realistic 3D model of the large-scale city buildings quickly and efficiently which becomes the research hotspot. In this thesis, a novel 3D modeling approach is proposed to quickly and efficiently build 3D model of large-scale city buildings based on shape grammar and facade rule modeling. Building Information Model (BIM) is an important technical means to enhance the construction industry, for the city building design and construction, how to better research and application of BIM technology which is the key, in this thesis City Building Integrated Information Model (CBIIM) is specified to manage the information of building lifecycle effectively and realize the information sharing and exchanging. This thesis has studied the acquisition and processing of the modeling data. Google Earth and ArcGIS software are mainly used to acquire and process image-maps data and elevation-maps data of the target area, these two kinds of data match and overlay, which can generate 3D city terrain data with geographic location information. Then OpenStreetMap is used to acquire road data of the target area, and it can be optimal processed to the necessary road network by JOSM software. 3D laser scanning technology is used to collect building surface texture images and create the point clouds model of the target architecture modeling so as to get the modeling dimensions by measurement. On this basis, this thesis mainly has studied the principle and the process of CGA rule to create building models, and studied the method that can separate architectural elements using image segmentation to generate CGA rule automatically and to create building model furtherly. Thus 3D building models have been established in the CityEngine software using CGA rules and facade modeling technology. This thesis has specified the City Building Integrated Information Model (CBIIM) based on BIM. The city building information are classified and integrated, and the building and component was described with the IFC standard, in order to manage the informations of building lifecycle effectively. This thesis studies the integrated information association model technology, that it can realize standardized component design with associated features and intelligent building design with associated parameters in knowledge rules combined with IFC. The construction simulation technology is studied. The knowledge rules in the integrated information model provide a reliable reference for the construction simulation, and the simulation scene is created through the invoking the integrated information model, thus the construction simulation process is completed by the program. Taking Baoshan Campus of Shanghai University as an example, the modeling process of the whole scene is illustrated, and the modeling steps of all kinds of 3D objects are described in detail to solve the specific problems in the actual modeling process. Thus the feasibility and validity of the procedural intelligent modeling approach are verified. Taking the dormitory of Shanghai University as an example, a simulation scene and the simulation model were created by the integrated informations, combined with the relevant construction information the construction simulation was completed by the program. Thus the feasibility and validity of the CBIIM are verified
Blanchard, Robert D. "Nose fairing modeling and simulation to support Trident II D5 lifecycle extension." Thesis, Monterey, California: Naval Postgraduate School, 2013. http://hdl.handle.net/10945/37588.
Full textThe objective of this thesis is to evaluate a modeling and simulation tool for the analysis of the Trident II D5 missile nose fairing to determine the limitations of serviceability through the extended service life of the D5 missile. The benefit of this analysis is a means to evaluate and manage the remaining nose fairing supply and serve as a baseline for future production of nose fairings. Constructed of a Sitka spruce and fiberglass laminate, the nose fairing is designed as the lifting point of the missile for submarine onloads and offloads and supports the entire weight of the missile. A computer model of the nose fairing was used to evaluate the nose fairing under tensile and compressive loading conditions to simulate the lifting evolution and closure segment impact at time of launch. Changes in the material properties of the model allow for a simulation of aging in the nose fairing to estimate the performance degradation over time, as well as exploration of the applicability of new materials to any future design of nose fairings.
Johnston, Reuben Aaron. "A Multivariate Bayesian Approach to Modeling Vulnerability Discovery in the Software Security Lifecycle." Thesis, The George Washington University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10828524.
Full textSoftware vulnerabilities that enable well-known exploit techniques for committing computer crimes are preventable, but they continue to be present in releases. When Blackhats (i.e., malicious researchers) discover these vulnerabilities they oftentimes release corresponding exploit software and malware. If vulnerabilities—or discoveries of them—are not prevented, mitigated, or addressed, customer confidence could be reduced. In addressing the issue, software-makers must choose which mitigation alternatives will provide maximal impact and use vulnerability discovery modeling (VDM) techniques to support their decision-making process. In the literature, applications of these techniques have used traditional approaches to analysis and, despite the dearth of data, have not included information from experts and do not include influential variables describing the software release (SR) (e.g., code size and complexity characteristics) and security assessment profile (SAP) (e.g., security team size or skill). Consequently, they have been limited to modeling discoveries over time for SR and SAP scenarios of unique products, whose results are not readily comparable without making assumptions that equate all SR and SAP combinations under study. This research takes an alternative approach, applying Bayesian methods to modeling the vulnerability-discovery phenomenon. Relevant data were obtained from expert judgment (i.e., information elicited from security experts in structured workshops) and from public databases. The open-source framework, MCMCBayes, was developed to perform Bayesian model averaging (BMA). It combines predictions of interval-grouped discoveries by performance-weighting results from six variants of the non-homogeneous Poisson process, two regression models, and two growth-curve models. Utilizing expert judgment also enables forecasting expected discoveries over time for arbitrary SR and SAP combinations, thus helping software-makers to better understand the effects of influential variables they control on the phenomenon. This requires defining variables that describe arbitrary SR and SAP combinations as well as constructing VDM extensions that parametrically scale results from a defined baseline SR and SAP to the arbitrary SR and SAP of interest. Scaling parameters were estimated using elicited multivariate data gathered with a novel paired comparison approach. MCMCBayes uses the multivariate data with the BMA model for the baseline to perform predictions for desired SR and SAP combinations and to demonstrate how multivariate VDM techniques could be used. The research is applicable to software-makers and persons interested in applications of expert-judgment elicitation or those using Bayesian analysis techniques with phenomena having non-decreasing counts over time.

Full textWithin the current economic context, enterprises are facing new interoperability issues due to increasing needs of eBusiness Collaboration within the emerging digital ecosystems they belong to. They also need to be able to keep in pace with their heterogeneous internal legacy systems. In addition, they should not have to modify their infrastructure or applications for fast and short collaboration implying information and knowledge interchange with new partners of their ecosystem. In one hand, current solutions are less and less adapted to face increasing needs and complexity in term of interoperability. In the other hand, legacy interoperability standards and frameworks can’t be replaced as it can be imagined to propose new disruptive approach and technologies. The research work undertaken for the thesis “Interoperability of Technical Enterprise Interoperability” consists in proposing an innovative approach allowing a given and mature ecosystem to build an enterprise application interoperability framework based on simultaneous and coherent usage of eBusiness standards used by a given ecosystem, combining usage of the different relevant frameworks supporting these standards. The goal is achievement of "pragmatic" interoperability. Proposed innovative approach takes advantage of simultaneous usage of Model Driven Engineering, Enterprise Modeling, Ontology and Service Oriented Architecture. It promotes systematic usage of commodities on the WEB based on open and governed standards. Doing so, semantic preservation between ecosystem’s standards, application engineering artifacts and communication infrastructures is crucial. To support semantic preservation within the context of the innovative proposed approach, the concept of “extended hypermodel” is developed and demonstrated within the context of Product Lifecycle Management within networked organizations
Vadoudi, Kiyan. "Data Model Proposal to Integrate GIS with PLM for DfS." Thesis, Troyes, 2017. http://www.theses.fr/2017TROY0014/document.
Full textThere are different approaches to implement sustainability and Design for Sustainability (DfS) is the one that give more accurate result by considering both global and regional scales. Integration of Life Cycle Assessment (LCA) into Product Lifecycle Management (PLM) is an example of tool integration to support sustainability. In LCA framework, Life Cycle Inventory (LCI) is the quantified and classified list of input and output flow of the LCA model that is a model of the product system, linking the technological system to the ecosphere (Environment system). As each region has a unique environmental system, design characteristics and specifications of technological system should be modified and adopted based on these differences. Implementation of this approach will require geographical information of interacted environmental systems, which is a kind of new strategy in DfS. Therefore, we tested the interest of the integration of Geographical Information Systems (GIS) with PLM to support geographical considerations during product development activities. The main research question of this research work is then how to propose this PLM-GIS integration for DfS. Thus, we conducted that literature review on existing data models about product, environment, geography and their combination is a key to prove the link among them

Full textSmart tillverkning – smarta fabriker som skapar smarta produkter – är ett ämne som inom det akademiska och affärsmässiga området förekommer alltmer frekvent. Denna uppsats behandlar smart tillverkning i kontexten av Product Life Cycle Support (PLCS). Uppsatsen undersökte hur PLCS kunde utnyttjas för att möjliggöra smart tillverkning, med huvudsakligt fokus på möjliggörandet av den bakomliggande system- och informationsinfrastrukturen för smart tillverkning. Standarder, rapporter och specifikationer för smart tillverkning undersöktes. Flertalet informationsmodeller skapades utifrån dessa publikationer vilka kunde användas för att implementera ett förslag för infrastrukturen.Implementationen hade sin bas i det pågående forskningsprojektet DigIn, och använde de utvecklade modellerna för att implementera en föreslagen lösning i produktlivscykel-mjukvaran ShareAspace. Detta gjordes för att utvärdera hur funktionaliteten i ShareAspace och PLCS skulle kunna användas för att stödja smart tillverkning och uppdatera den digitala tvillingen. Parallellt med denna implementation genomfördes i DigIn ett projekt vilka kopplade samman databasen med annan mjukvara i systemet samt fabriksgolvet. Lösningen använde en Plant Service Bus (Kafka) och REST APIer för att koppla samman dessa. Funktionaliteten av systemet rörande specificerade krav som återfanns i publikationerna undersöktes sedan.Lösningen fanns möta de flesta av de krav som lades fram i de undersökta publikationerna rörande, bland annat, livscykelshantering, tjänsteorienterad arkitektur, icke-hierarkiska strukturer samt kommunikationsmöjligheter.

Full textJämfört med de större företagen är det i Sverige inte lika vanligt att små och medelstora företag (SME) jobbar med miljöfrågor. Detta beror delvis på att hållberhetsredovisningskraven inte gäller SME, men också på grund av att SME saknar resurser, tid, pengar, kompetens samt att kunderna inte alltid ställer krav kring att driva de frågorna. Genom att utveckla modeller kring hur man beräknar och redovisar växthusgasutsläpp (GHG) och vattenanvändning för ett företag är tanken att examensarbetet ska underlätta SME:s miljöarbete och locka flera SME till att adressera de miljörelaterade utmaningarna. Examensarbetet är uppdelat i två sektioner. Först tas en teoretisk modell fram med inriktning mot parti- och detaljhandelssektorn, där avgränsningarna är dragna i enlighet med GHG protokollstandarden och redovisningsprinciper för vattenanvändning. Modellen implementeras sedan som verktyg i MS Excel, med inbyggda beräknings- och rapporteringsfunktioner. Verifiering av modellen görs genom tillämpning av verktyget på Snacksbolaget, ett fallstudieföretag som har en grossistverksamhet inom hotell, restaurang och cateringbranschen. Inventeringsresultatet visar att Scope 3 GHG-utsläppen är störst i Snacksbolagets totala utsläppsprofil 2019, vilken är ganska typisk för partihandeln. Av Scope 3 utsläppen är materialutvinning och produkttillverkningsfaserna av de köpta produkterna det som bidrar till största delen, samtidigt som utsläppen från transport-kategorier sådan som Scope 1, Scope 3.4 och Scope 3.9 också är signifikanta. Inventeringen av vattenanvändning visar att produkttillverkningsfasen kräver den högsta vattenvolymen, där en relativ stor del är indirekt vatten som användas i elproduktionen. Inventeringsresultatet och känslighetsanalysen visar de potentiella åtgärder företaget kan implementera för att påverka storleken av Scope 3 emissionen och indirekta vattenanvändningen. Företaget rekommenderas att överväga sina produktval genom att utvärdera miljöprestationen genom att analysera flera miljöparametrar / miljödimensioner. Dessutom bör de inskaffa den underliggande produktinformation från leverantörerna för att säkerställa att man tar hänsyn till en korrekt produktlivscykel och validera de miljöfördelar som framhävs av leverantören. Det är också viktigt att välja produkter där materialet utvinns i, och produktens tillverkning sker i, länder eller regioner som utnyttjar förnybar energi och samtidigt inte är drabbat av vattenbrist. Företaget kan även motivera leverantören att frakta varorna med gröna transportalternativ. Sist men inte minst kan företaget uppmuntra till mindre konsumtion genom att erbjuda tjänster som uthyrning och återanvändning av produkter. Vidareutveckling av modellen inom parti- och detaljhandelssektorn kommer att kräva ytterligare data, tid och kompentens. Medan utvidgning av modellen för att omfatta andra affärssektor kan uppnås genom att utveckla separata modeller med likande tillvägagångssätt som beskrivs för den nuvarande modellen. Datakvaliteten kan förbättras under tiden genom regelbunden underhållning och uppdatering. För att kunna locka till sig fler små och medelstora företag, bör anpassande modeller utvecklas och underhålls av externa miljöexperter och göras tillgängliga för användning av SME.

Full textThe digital growth of the construction industry led to BIM (Building Information Modeling). Developed for buildings, BIM is later used on linear infrastructure projects. Such projects require end-to-end control of information. PLM (Product Lifecycle Management) supports digital continuity in the manufacturing industry. Studies evaluate the relevance of a complementary use of the BIM and PLM approaches for linear infrastructure projects. With an adaptation of methods used for building construction, those studies are mostly restricted to the implementation of data repositories. This makes it difficult to consider the infrastructure post-construction phase, where the 3D model is no longer a digital model, but a digital twin. This research work consists in developing a strategy for the design, the implementation and the operations and maintenance of a linear infrastructure. The digital twin of the infrastructure is the target of our approach. It will take into consideration not only BIM and PLM methodologies, but also any other data source positioning the infrastructure in its geographical environment. Data aggregator, our digital twin should make it possible to manage the lifecycle of a linear infrastructure. This system is tested on a specific linear infrastructure, a level crossing. Digital continuity and data traceability are important factors for those constructions. Through the digital twin, our proposal helps to follow the data, and thus to link operational data to the design and construction data of the linear infrastructure

In the domain of software engineering, software lifecycle management is an important issue to study. However, it is not easy for a software development team, especially for those medium and small ones, to build an adequate lifecycle management solution. It is also not a trivial job to implement the solution by just adopting commercial or open source available management tools. Therefore, in this thesis we propose a rapid software lifecycle management modeling and implementing method called RALM (Rapid Application Lifecycle management Modeling) to help software development teams implementing their required management solutions as easily as possible. Based on templates and ALM-XML standard format, a software team can rapidly define its lifecycle management solution. In order to show the superiority of RALM, we further implement a tool called ALM2VSTS such that it can automatically transfer the solution definition into Microsoft ® Visual Studio 2005 Team System (VSTS) process template, configuration guidance, and engineering practice portal.

Bridge MR&R costs can be more objectively estimated if adequate historical data are collected and well processed, also a proper deterioration model is adopted. This study will first demonstrate a systematic approach to explore the key factors leading to bridge deterioration. The representative samples of bridges with similar behaviors of deterioration are then classified by the identified factors. A new condition index (NCI) is defined and the reliability index (Beta) is introduced to measure the deterioration quantitatively. The deterioration trend of the representative samples can then be determined. Finally, the maintaining cost of a bridge with the same deterioration behavior can be estimated. This study achieved the following objects: 1. Identifying the key factors leading to deterioration towards bridge elements; 2. Developing a bridge matching system to retrieve bridge samples by their attributes; 3. Developing a reliability-based deterioration model of bridge elements; 4. Demonstrating a systematic approach to estimate the MR&R cost of bridges.

Full textComplex Event Processing (CEP) has become increasingly popular within organizations. The financial industry used to be the sole beneficiary of the CEP capabilities, however nowadays we see it increasingly being adopted by non-financial companies, especially for Business Activity Monitoring software (BAM). One of the most distinctive features of CEP is pattern matching. In this field, pattern matching should not be mistaken for the pattern matching in character strings, nor pattern matching from the functional programming paradigm. Rather, it specifies temporal relationships between events, such as sequences, restrictions of event occurrences, just to name a few. On the other hand, one feature which has yet to be widely adopted amongst the CEP engines is entity state and lifecycle modeling, i.e., the ability to correlate events into instances of an entity, where each entity will have di↵erent states and transitions representing its lifecycle. The objective of this work is to investigate and implement this type of functionality in Feedzai Pulse’s query language - PQL.
