A Trusted Autonomic Architecture to Safeguard Cyber-Physical Control Leaf Nodes and Protect Process IntegrityChiluvuri, Nayana Teja 16 September 2015 (has links)
Cyber-physical systems are networked through IT infrastructure and susceptible to malware. Threats targeting process control are much more safety-critical than traditional computing systems since they jeopardize the integrity of physical infrastructure. Existing defence mechanisms address security at the network nodes but do not protect the physical infrastructure if network integrity is compromised. An interface guardian architecture is implemented on cyber-physical control leaf nodes to maintain process integrity by enforcing high-level safety and stability policies.
Preemptive detection schemes are implemented to monitor process behavior and anticipate malicious activity before process safety and stability are compromised. Autonomic properties are employed to automatically protect process integrity by initiating switch-over to a verified backup controller. Subsystems adhere to strict trust requirements safeguarding them from adversarial intrusion. The preemptive detection schemes, switch-over logic, backup controller, and process communication are all trusted components that are separated from the untrusted production controller.
The proposed architecture is applied to a rotary inverted pendulum experiment and implemented on a Xilinx Zynq-7000 configurable SoC. The leaf node implementation is integrated into a cyber-physical control topology. Simulated attack scenarios show strengthened resilience to both network integrity and reconfiguration attacks. Threats attempting to disrupt process behavior are successfully thwarted by having a backup controller maintain process stability. The system ensures both safety and liveness properties even under adversarial conditions. / Master of Science

Méthode agile pour la conception collaborative multidisciplinaire de systèmes intégrés : application à la mécatronique / Agil method for the multidisciplinary and collaborative design of integrated systems : application to mechatronicsBricogne-Cuignières, Matthieu 13 February 2015 (has links)
Ces travaux portent sur la conception multidisciplinaire de systèmes intégrés. Ces systèmes sont soumis à un nombre d’exigences toujours croissant, entraînant des besoins en termes d’intégration fonctionnelle et spatiale. Ces différents types d’intégration relative au produit sont également la source d’une complexité organisationnelle, provenant à la fois de la multitude d’acteurs réalisant différentes activités d’ingénierie, mais également de la diversité des domaines impliqués, désignée dans ce manuscrit par « intégration multidisciplinaire ». Pour favoriser cette intégration multidisciplinaire, les phases de « conception préliminaire » et de « conception détaillée » ont été identifiées comme déterminantes, notamment car elles se caractérisent par la collaboration de nombreux experts, manipulant un grand nombre de données techniques de définition. Les systèmes conçus lors de conceptions multidisciplinaires restent faiblement intégrés. Cela est en partie dû au cloisonnement entre les disciplines et à un mode d’organisation projet basé sur une planification prédominante, caractérisé notamment par une diffusion de l’information principalement descendante (top-down). Afin d’assurer une meilleure collaboration entre ces différentes disciplines, de permettre des prises de décision éclairées par des indicateurs opérationnels et de pouvoir analyser et mieux comprendre les phénomènes d’intégration des expertises, l’introduction d’une méthode inspirée des principes fondateurs des méthodes agiles est proposée pour la conception collaborative de systèmes intégrés.La contribution de ces travaux s’appuie sur trois concepts complémentaires. Le premier, intitulé Collaborative Actions Framework correspond à un cadre de collaboration opérationnelle autour d’actions. Un des objectifs de ce framework est de faciliter la collaboration des acteurs des projets de conception, quelle que soit leur origine disciplinaire, mais également d’assurer une traçabilité entre les prises de décision et les corrections/modifications apportées sur les données techniques. Cette traçabilité est rendue possible grâce aux liens existants avec le second concept intitulé Workspace. Apportant un nouvel éclairage sur les possibilités offertes par la collaboration autour de ces espaces de collaboration, ce concept offre un certain nombre de possibilités,notamment la mise en commun continue des travaux, l’intégration multidisciplinaire et la validation des modifications. Les échanges de données techniques entre les workspaces, ou le travail simultané sur les mêmes données techniques, s’appuient quant à eux sur la possibilité de pouvoir gérer de façon parallèle différentes versions d’une même donnée technique. Ces possibilités sont proposées par le troisième concept, intitulé branch & merge, qui permet également à différents acteurs de travailler simultanément sur les mêmes données. Enfin, ces trois concepts sont ensuite illustrés par l’intermédiaire d’un démonstrateur composé d’un scénario et d’un prototype informatique. Un produit mécatronique, combinaison synergique et systémique de la mécanique, de l'électronique et de l'informatique temps réel, est utilisé afin d’illustrer les possibilités offertes par nos travaux en termes d'intégration multidisciplinaire lors de la conception collaborative. / This work focuses on the multidisciplinary and collaborative design of integrated systems. These systems are subject to an ever increasing number of requirements, leading to the need for more comprehensive functional and spatial integration. These different types of product integration are also at the origin of organizational complexity. This complexity arises not only from the great number of actors performing various engineering activities but also from the diversity of disciplines involved (designated in this manuscript as “multidisciplinary integration”). To encourage this multidisciplinary integration, “preliminary design” and “detailed design” have been identified as the most significant steps, especially since they are characterized by the collaboration of multiple experts handling a large number of product definition’ technical data. Systems that have been designed thanks to multidisciplinary approaches are generally poorly integrated. This is partially due to the compartmentalization of disciplines, as well as to the “project-planned” method, where project planning is predominant and information is mainly spread out “top-down”. To ensure better cooperation between the various disciplines, to enable decision making based on operational indicators and to analyze and understand the multidisciplinary integration processes, a method inspired by the founding principles of agile methods (the agile manifesto) is proposed for the collaborative design of integrated systems. This work is based on three complementary concepts. The first is, the Collaborative Actions Framework, an operational framework for collaboration around actions. One objective of this framework is to improve the collaboration among designers, whatever their disciplinary origin. It also ensures traceability between decision making and corrections/changes made to technical data. This traceability is made possible by the useof the second concept, called Workspace. Even if this term is already well known, we propose a new definition/usage to transform it into collaboration spaces. This concept offers great possibilities, including the continuous delivering/sharing of experts’ contributions, multidisciplinary integration and change validation. The exchange of technical data between workspaces, or simultaneous work on the same data, relies on the ability to manage several parallel versions of the same item into a single datamanagement system. These opportunities are offered by the third concept, called Branch & Merge. Finally, these three concepts are illustrated through a scenario and a computer prototype. A mechatronic product, “the synergistic combination of mechanical and electrical engineering, computer science, and information technology” (Harashima et al., 1996), is used to illustrate the opportunities offered by our work in terms of multidisciplinary integration during collaborative design.

Návrh mezioperační dopravy ve výrobním podniku podle principů Průmyslu 4.0 / Design of inter-operational transport in a manufacturing company according to the Industry 4.0 conceptMravec, Roman January 2021 (has links)
Based on the description and definition of technology and processes falling within the vision of the fourth industrial revolution with the aim of creating intelligent factories, this diploma thesis deals with the principles of the Industry 4.0 concept in Hilti's production plant with a focus on transport and supply of production equipment. The aim of the work is to create a comprehensive proposal that takes into account all the necessary aspects associated with upgrading the existing state of inter-operational transport in a particular production line to fully automated, flexible and autonomous transport of materials and products in the context of Industry 4.0. A prerequisite for creating a design is the connection of automatically guided vehicles (AGVs) serving individual transport orders. The selection of the vehicle was made taking into account the safety of movement, the method of charging, the system and network integrity of existing and proposed technologies and components. The intention is not only to automate the inter-operational service, but also on the basis of the created automation concept, the ability to autonomously procure the flow of material and products. The mathematical calculation of capacity planning in the production line helped to determine the total load and the number of vehicles needed for continuous procurement of transport requirements. The result of the design part is also the design of specific transport routes and transport conditions that AGV vehicles must comply with in order to maintain a high level of safety. Transparency and a constant overview of transported products is provided by the presented scheme for identification of production batches, Auto-ID system. The financial efficiency of the whole project elaborated in the diploma thesis is evaluated as payable after 4 years from the implementation of the proposal. The financial efficiency of the whole project elaborated in the diploma thesis is evaluated as payable after 4 years from the implementation of the proposal due to high labor costs.

Engineering Ecosystems of Systems: UML Profile, Credential Design, and Risk-balanced Cellular Access ControlBissessar, David 14 December 2021 (has links)
This thesis proposes an Ecosystem perspective for the engineering of SoS and CPS
and illustrates the impact of this perspective in three areas of contribution category
First, from a conceptual and Systems Engineering perspective, a conceptual framework
including the Ecosystems of System Unified Language Modeling (EoS-UML) profile, a
set of Ecosystem Ensemble Diagrams, the Arms :Length Trust Model and the Cyber
Physical Threat Model are provided. Second, having established this conceptual view of
the ecosystem, we recognize unique role of the cryptographic credentials within it,
towards enabling the ecosystem long-term value proposition and acting as a value
transfer agent, implementing careful balance of properties meet stakeholder needs.
Third, we propose that the ecosystem computers can be used as a distributed compute
engine to run Collaborative Algorithms. To demonstrate, we define access control
scheme, risk-balanced Cellular Access Control (rbCAC). The rbCAC algorithm defines
access control within a cyber-physical environment in a manner which balances cost,
risk, and net utility in a multi-authority setting. rbCAC is demonstrated it in an Air Travel
and Border Services scenario. Other domains are also discussed included air traffic
control threat prevention from drone identity attacks in protected airspaces.
These contributions offer significant material for future development, ongoing credential
and ecosystem design, including dynamic perimeters and continuous-time sampling,
intelligent and self optimizing ecosystems, runtime collaborative platform design
contracts and constraints, and analysis of APT attacks to SCADA systems using
ecosystem approaches.

Improving supply chain visibility within logistics by implementing a Digital Twin : A case study at Scania Logistics / Att förbättra synlighet inom logistikkedjor genom att implementera en Digital Tvilling : En fallstudie på Scania LogisticsBLOMKVIST, YLVA, ULLEMAR LOENBOM, LEO January 2020 (has links)
As organisations adapt to the rigorous demands set by global markets, the supply chains that constitute their logistics networks become increasingly complex. This often has a detrimental effect on the supply chain visibility within the organisation, which may in turn have a negative impact on the core business of the organisation. This paper aims to determine how organisations can benefit in terms of improving their logistical supply chain visibility by implementing a Digital Twin — an all-encompassing virtual representation of the physical assets that constitute the logistics system. Furthermore, challenges related to implementation and the necessary steps to overcome these challenges were examined. The results of the study are that Digital Twins may prove beneficial to organisations in terms of improving metrics of analytics, diagnostics, predictions and descriptions of physical assets. However, these benefits come with notable challenges — managing implementation and maintenance costs, ensuring proper information modelling, adopting new technology and leading the organisation through the changes that an implementation would entail. In conclusion, a Digital Twin is a powerful tool suitable for organisations where the benefits outweigh the challenges of the initial implementation. Therefore, careful consideration must be taken to ensure that the investment is worthwhile. Further research is required to determine the most efficient way of introducing a Digital Twin to a logistical supply chain. / I takt med att organisationer anpassar sig till de hårda krav som ställs av den globala marknaden ökar också komplexiteten i deras logistiknätverk. Detta har ofta en negativ effekt på synligheten inom logistikkedjan i organisationen, vilken i sin tur kan ha en negativ påverkan på organisationens kärnverksamhet. Målet med denna studie är att utröna de fördelar som organisationer kan uppnå vad gäller att förbättra synligheten inom deras logistikkedjor genom att implementera en Digital Tvilling — en allomfattande virtuell representation av de fysiska tillgångar som utgör logistikkedjan. Resultaten av studien är att Digitala Tvillingar kan vara gynnsamma för organisationer när det gäller att förbättra analys, diagnostik, prognoser och beskrivningar av fysiska tillgångar. Implementationen medför dock utmaningar — hantering av implementations- och driftskostnader, utformning av informationsmodellering, anammandet av ny teknik och ledarskap genom förändringsarbetet som en implementering skulle innebära. Sammanfattningsvis är en Digital Tvilling ett verktyg som lämpar sig för organisationer där fördelarna överväger de utmaningar som tillkommer med implementationen. Därmed bör beslutet om en eventuell implementation endast ske efter noggrant övervägande. Vidare forskning behöver genomföras för att utröna den mest effektiva metoden för att introducera en Digital Tvilling till en logistikkedja.

Facilitating an Industry 4.0 ImplementationLarsson, Louise, Nilsson, Jennie January 2019 (has links)
We are today facing an industrial revolution called Industry 4.0. Earlier in the human history, we have seen multiple industrial revolutions, but only after they actually happened. This is the first time we can see that an industrial revolution is on its way. Witht his knowledge, we have the chance to prepare for this large‐scaled technological change that we are standing in front of. Because of the impact that earlier industrial revolutions had on organizations, we can assume that Industry 4.0, as well, will impact and change work, tasks and the organizations themselves; especially when it comes to new high‐tech knowledge and skills that need to be learnt. Implementation, change, and high‐tech learning, together with a constantly running production can be stressful for anyone involved. For this reason, the purpose of this study is to come up with solutions on how you can facilitate the implementation of Industry 4.0, for employees and in an organizational point of view. We do this by conducting a literature study as well as interviewing organizations within the Swedish manufacturing industry. The structure of the analysis is built upon Lewin’s Three‐stage Model of Change. Here, we discuss and present solutions according to the stage in which they fit during the change process. Additionally, we investigate the concept of gamification as a tool to facilitate change. From our research, we conclude that motivation and engagement are keys in a technological change project such as Industry 4.0. Involvement, transparency and clarity are important aspects to make employees engaged throughout the project. Additionally, we present practical solutions for how organizations can educate their employees within Industry 4.0 techniques, as well as increase their motivation and engagement. / Vi står idag inför en industriell revolution som kallas Industri 4.0. Tidigare i historien har vi sett industriella revolutioner först efter att de inträffat. Det är nu första gången vi kanse att en industriell revolution är på väg. Med denna kunskap har vi idag en möjlighet att förbereda oss för den teknologiska utveckling som vi står inför. På grund av de tidigare industriella revolutionerna och den stora påverkan som de har haft på organisationer, kan vi anta att Industri 4.0 också kommer förändra jobb, uppgifter och organisationer – framför allt när det kommer till den nya teknologiska kunskap som nya maskiner och system kommer kräva av de som använder dem. Implementering, förändring och en hög nivå av teknologiskt lärande, samtidigt som produktionen fortfarande kommer snurra dygnet runt, kan vara stressigt för vem som helst. Därför syftar detta examensarbete till att ta fram lösningar för hur man kan förenkla implementationen av Industri 4.0, ur ett medarbetarperspektiv och för organisationen som helhet. Vi gör detta genom en litteraturstudie och genom intervjuer med organisationer inom den svenska tillverkningsindustrin. Strukturen på analysen bygger på Lewins trestegsmodell för förändring. Här diskuterar och presenterar vi lösningar enligt vilket steg de passar in i under förändringsprocessen. Vidare utvärderar vi gamification som ett verktyg för att underlätta förändringen. Detta arbete kommer fram till att det viktigaste för att genomföra ett förändringsarbete i denna omfattning är motivation och engagemang från både anställda och ledning. Involvering, transparens och tydlighet är viktiga delar för att göra anställda engagerade genom hela projektet. Vidare presenterar vi lösningar för hur man kan utbilda sina anställda inom Industri 4.0‐tekniker, och även för hur man kan öka motivation och engagemang.

Unternehmen werden gegenwärtig mit den Themen der Nachhaltigkeit und der fortschreitenden Industrie 4.0 vor immer komplexere Herausforderungen gestellt. Ein Bestandteil der neuen Basistechnologien stellen cyber-physische Systeme (CPS) dar, die bereits gegenwärtig und zukünftig mit den Zielen der nachhaltigen Entwicklung in Einklang gebracht werden müssen. Die vorliegende Arbeit geht den Forschungsfragen nach, wie CPS definiert, charakterisiert und unter Einbezug nachhaltiger Kriterien bewertet werden können. Dazu wurden verschiedene, betriebswirtschaftliche Instrumentarien ausgewählt und systematisiert, die folgend im eigens entwickelten und angewandten „Vorgehensmodell zur Prüfung und Eignung
von Bewertungsinstrumenten für CPS unter Einbezug der Nachhaltigkeit“ überprüft wurden.
Die Untersuchung ergab, dass der Bedarf an Bewertungsansätzen von CPS in Kombination mit der Thematik der Nachhaltigkeit besteht und mit existenten, betriebswirtschaftlichen Methoden größtenteils bewältigt werden kann.
Die zugrunde liegende Masterarbeit wurde an der Professur Unternehmensrechnung und Controlling (Technische Universität Chemnitz) durch Prof. Dr. Prof. h. c. Uwe Götze sowie Kristina Höse (M.Sc.) betreut. / Companies are currently facing increasingly complex challenges with the issues of sustainability and the advancing Industry 4.0. One component of the new enabling technologies are cyber-physical systems (CPS), which already currently and in the future need to be aligned with sustainable development goals. This thesis addresses the research questions of how CPS can be defined, characterized and evaluated with respect to sustainable criteria. For this purpose, various business management tools were selected and systematized, which were subsequently reviewed in the specially developed and applied 'Procedure Model for the Examination and Suitability of Assessment Tools for CPS with the Inclusion of Sustainability'. The investigation showed that the need for evaluation approaches of CPS in combination with the topic of sustainability exists and can be handled with existing, business management methods to a large extent.
