▼ Information systems development (ISD) outsourcing projects employ modularisation to decompose complex tasks into simpler portions. Modularisation enables better management and control. Adopting a ‘control theory’ perspective, this research explored the mechanisms for managing modularised ISD outsourcing projects effectively. Results are drawn using the case study method, employing eight modularised ISD outsourcing projects. Results demonstrate that modularisation increases the use of formal controls and decreases the informal clan controls. Further, it was found that an error in modualrisation creates fluctuations in Business Requirement Specifications.

▼ Bakgrund: Användningen av inhyrd personal har ökat till följd av ett ökat krav på flexibilitet och ingår numera allt oftare i personalstyrkan. Däremot inkluderas sällan den inhyrda personalen i den styrning som utformats för den ordinarie personalen. Styrning används för att påverka personalens beteenden så att de blir målkongruenta. Därför är det intressant att undersöka om inhyrd personal saknar ett målkongruent beteende och således har en negativ inverkan på företagets målkongruens. Syfte: Studiens syfte är att undersöka om och varför beteenden överlag skiljer sig åt mellan inhyrd och ordinarie personal hos ett valt företag. Forskningen skapar en djupare förståelse för hur inkludering/exkludering i olika styrmekanismer kan påverka de inhyrdas bidrag till målkongruens. Metod: Studien tillämpar en kvalitativ forskningsstrategi med en induktiv ansats. Den forskningsdesign som tillämpats är en enfallsstudie. Empirin till studien har samlats in genom kvalitativa intervjuer med både inhyrd och ordinarie personal samt deras närmsta chef. Materialet har sedan analyserats och tolkats för att besvara forskningsfrågorna. Slutsats: Studien fann att de inhyrda medarbetarna har ett mindre målkongruent beteende än de ordinarie. Skillnaden beror framförallt på de inhyrdas exkludering från företagets formella styrmetoder. Att de inhyrda för det mesta inkluderas i de informella styrmetoderna förklarar varför de inhyrda till viss del ändå uppvisar ett målkongruent beteende.
Background: The use of temporary staff has increased as a result of an increased demand for flexibility and is now increasingly included in the personnel force. Despite that, the temporary staff are rarely included in the control designed for the ordinary staff. Control is used to influence staff behavior so that they become goal-congruent. Therefore, it is interesting to investigate if the temporary staff lack a goal congruent behavior and thus have a negative impact on the company's goal congruence. Purpose: The purpose of the study is to investigate whether and why behaviors differ between temporary and ordinary staff, at a chosen company. The research creates a deeper understanding about how the inclusion/ exclusion in different control mechanisms influence the temporary staff to contribute to the target congruence Method: The study applies a qualitative research strategy with an inductive approach. The research design that has been applied is a case study at a chosen company. The empirical study has been collected through qualitative interviews with both temporary and ordinary staff and their closest manager. The material has then been analyzed and interpreted to answer the research questions. Conclusion: The study found that the temporary staff have a less goal-congruent behavior than the ordinary staff. The difference is mainly due to the temporary’s exclusion from the…

▼ Cette thèse contribue à l’étude de la fiabilité et de la sécurité-innocuité des systèmes informatisés, modélisés par des systèmes à événements discrets. Les principales contributions concernent la théorie des Systèmes de Contrôle (notés C Systems) et l’approche par Monitoring des modèles.Dans la première partie de la thèse, nous étudions la théorie des Systèmes de Contrôle qui combine et étend de façon significative, les systèmes de réécriture de la théorie des langages et le contrôle supervisé. Un système de contrôle est une structure générique qui contient deux composants : le composant contrôlé et le composant contrôlant qui restreint le comportement du composant contrôlé. Les deux composants sont exprimés en utilisant le même formalisme comme des automates ou des grammaires. Nous considérons différentes classes de systèmes de contrôle basés sur différents formalismes comme, par exemple, les automates, les grammaires, ainsi que leurs versions infinies et concurrentes. Ensuite, une application de cette théorie est présentée. Les systèmes de contrôle basés sur les automates de Büchi sont utilisés pour vérifier par model-checking, des propriétés définissant la correction sur des traces d’exécution spécifiées par une assertion de type nevertrace.Dans la seconde partie de la thèse, nous investiguons l’approche de monitoring des modèles dont la théorie des systèmes de contrôle constitue les fondations formelles. Le principe pivot de cette approche est la «spécification de propriétés comme contrôleur». En d’autres termes, pour un système, les exigences fonctionnelles, d’une part, et des propriétés, d’autre part, sont modélisées et implantées séparément, les propriétés spécifiées contrôlant le comportement issu des exigences fonctionnelles. De cette approche découle ainsi deux techniques alternatives, respectivement nommées monitoring de modèle et génération de modèle. Cette approche peut être utilisée de diverses manières pour améliorer la fiabilité et la sécurité-innocuité de divers types de systèmes. Nous présentons quelques applications qui montrent l’intérêt pratique de cette contribution théorique. Tout d’abord, cette approche aide à prendre en compte les évolutions des spécifications des propriétés. En second lieu, elle fournit une base théorique à la sécurité fonctionnelle, popularisée par la norme IEC 61508. En troisième lieu, l’approche peut être utilisée pour formaliser et vérifier l’application de guides de bonnes pratiques ou des règles de modélisation appliquées par exemple pour des modèles UML.Ces résultats constituent les bases pour des études futures de dispositifs plus perfectionnés, et fournissent une nouvelle voie pour s’assurer de la fiabilité et de la sécurité-innocuité des systèmes

▼ Stop-and-Go Adaptive Cruise Control (ACC+) is an extension of Adaptive Cruise Control (ACC) that works at low speed as well as normal highway speeds to regulate the speed of the vehicle relative to the vehicle it is following. In this thesis, we design an ACC+ controller for a scale model electric vehicle that ensures the robust performance of the system under various models of uncertainty. We capture the operation of the hybrid system via a state-chart model that performs mode switching between different digital controllers with additional decision logic to guarantee the collision freedom of the system under normal operation. We apply different controller design methods such as Linear Quadratic Regulator (LQR) and H-infinity and perform multiple simulation runs in MATLAB/Simulink to validate the performance of the proposed designs. We compare the practicality of our design with existing formally verified ACC designs from the literature. The comparisons show that the other formally verified designs exhibit unacceptable behaviour in the form of mode thrashing that produces excessive acceleration and deceleration of the vehicle.
While simulations provide some assurance of safe operation of the system design, they do not guarantee system safety under all possible cases. To increase confidence in the system, we use Differential Dynamic Logic (dL) to formally state environmental assumptions and prove safety goals, including collision freedom. The verification is done in two stages. First, we identify the invariant required to ensure the safe operation of the system and we formally verify that the invariant preserves the safety property of any system with similar dynamics. This procedure provides a high level abstraction of a class of safe solutions for ACC+ system designs. Second, we show that our ACC+ system design is a refinement of the abstract model. The safety of the closed loop ACC+ system is proven by verifying bounds on the system variables using the KeYmaera verification tool for hybrid systems. The thesis demonstrates how practical ACC+ controller designs optimized for fuel economy, passenger comfort, etc., can be verified by showing that they are a refinement of the abstract high level design.

▼ Bakgrund: Interorganisatoriska relationer har blivit allt viktigare de senaste åren, företag köper exempelvis in IT-tjänster för att kunna förbättra sin kärnverksamhet. Det är dock vanligt att interorganisatoriska relationer misslyckas, en lösning till problem med dessa relationer är att använda ekonomisk styrning. En typ av relation som är speciellt utsatt för problematiken är relationen mellan små och medelstora företag, vilket är en grupp det saknas forskning och empiriska undersökningar om, trots dess stora inverkan på den svenska ekonomin. Ännu mer problematiskt blir det när dessa företag köper eller säljer tjänster, då hantering av tjänster kräver en större administrativ kunskap som mindre företag generellt inte besitter. Därmed är det av intresse att studera hur relationen mellan små och medelstora företag som hanterar tjänster ska styras på bästa sätt. Syfte: Syftet med studien är att skapa en modell över hur styrningen av interorganisatoriska relationer utformas och används av små och medelstora företag. Genomförande: Studien är en kvalitativ fallstudie med ett abduktivt angreppsätt. Empirisk data har samlats in genom semistrukturerade intervjuer på fem olika små och medelstora företag som köper och säljer tjänster, med syfte att framhäva perspektivet från båda partner i relationen. Resultat: Studiens resultat visar att det krävs en kombination av formella och informella styrmedel för att ha en fungerande interorganisatorisk relation. Avvägningen av olika styrverktyg beror på olika bakomliggande faktorer som präglar relationen mellan små och medelstora företag men resultatet tydliggör även att tillit och kommunikation har en stor inverkan på behovet av olika slags styrning. Samtidigt har kontraktet en väsentlig del av de studerade interorganisatoriska relationerna. Det är i kontraktet som bland annat finansiella och ickefinansiella målsättningar kan specificeras och kontraktet används som ett underlag för utförandet av tjänsten, uppföljning och avstämning, vilket inte alltid utförs i praktiken. Tilliten som finns mellan parterna i en relation påverkar hur kontraktet sedan används. Studien visar att formella styrmedel och tillit i vissa delar av relationen kan användas som substitut till varandra.
Background: The importance of interorganizational relationships has increased in recent years. Companies outsource peripheral components of their operations, such as IT, in order to focus on the main purpose of the company. It is common, however, for these relationships to fail and one solution to the problems arising from interorganizational relationships is the use of management control systems. Relationships between small and medium sized enterprises, in particular, present significant issues. Although they have a great impact on the Swedish economy, there are few scientific studies on them. These companies have an even harder time coping with interorganizational relationships when they are dealing…

▼ Current day VLSI systems have started seeing increasing percentages of multiple energy domain components being integrated into the mainstream. Energy domains such as mechanical, optical, fluidic etc. have become all pervasive into VLSI systems and such systems are being manufactured routinely. The framework required to design such an integrated
system with diverse energy domains needs to be evolved as a part of conventional VLSI design methodology. This is because manufacturing and design of these integrated energy domains although based on semiconductor processing, is still very ad-hoc, with each device requiring its dedicated design tools and process integration.
In this thesis three different approaches in different energy domains, have been pro-posed. These three domains include modelling & simulation, synthesis & compilation and
formal verification. Three different scenarios have been considered and it is shown that these tasks can be co-performed along with conventional VLSI circuits and systems.
In the first approach a micro-mechanical beam bending case is presented. A thermal heat ow causing the beam to bend through thermal stress is analyzed for change in capacitance under a single analysis and modelling framework. This involves a seamless analysis through thermal, mechanical and electrical energy domains. The second part of the thesis explores synthesis and compilation paradigms. The concept of a Gyro-compiler analogous to a memory compiler is proposed, which primarily generates soft IP models for various gyro topologies.
The final part of this thesis deals in showcasing a working prototype of a
formal verification framework for MEMS based hybrid systems. The MEMS verification domain today is largely limited to simulation based verification. Many techniques have been proposed for
formal verification of hybrid systems. Some of these methods have been extended to demonstrate, how MEMS based hybrid systems can be formally verified through ex-tensions of conventional
formal verification methods. An adaptive cruise
control (ACC)
system with a gyro based speed sensor has been analyzed and formally verified for various specifications of this
system.

▼ With the recent advances in communication and computation technologies, integration of software into the sensing, actuation, and
control is common. This has lead to a new branch of study called Cyber-Physical Systems (CPS). Avionics, automotives, power grid, medical devices, and robotics are a few examples of such systems. As these systems are part of critical infrastructure, it is very important to ensure that these systems function reliably without any failures. While testing improves confidence in these systems, it does not establish the absence of scenarios where the
system fails. The focus of this thesis is on
formal verification techniques for cyber-physical systems that prove the absence of errors in a given
system. In particular, this thesis focuses on {\em dynamic analysis} techniques that bridge the gap between testing and verification.
This thesis uses the framework of hybrid input output automata for modeling CPS.
Formal verification of hybrid automata is undecidable in general.
Because of the undecidability result, no algorithm is guaranteed to terminate for all models.
This thesis focuses on developing heuristics for verification that exploit sample executions of the
system. Moreover, the goal of the dynamic analysis techniques proposed in this thesis is to ensure that the techniques are sound, i.e., they always return the right answer, and they are relatively complete, i.e., the techniques terminate when the
system satisfies certain special conditions. For undecidable problems, such theoretical guarantees are the strongest that can be expected out of any automatic procedure. This thesis focuses on safety properties, which require that nothing bad happens. In particular we consider invariant and temporal precedence properties; temporal precedence properties ensure that the temporal ordering of certain events in every execution satisfy a given specification.
This thesis introduces the notion of a discrepancy function that aids in dynamic analysis of CPS. Informally, these discrepancy functions capture the convergence or divergence of continuous behaviors in CPS systems. In
control theory, several proof certificates such as contraction metric and incremental stability have been proposed to capture the convergence and divergence of solutions of ordinary differential equations. This thesis establishes that discrepancy functions generalize such proof certificates. Further, this thesis also proposes a new technique to compute discrepancy functions for continuous systems with linear ODEs from sample executions.
One of the main contributions of this thesis is a technique to compute an over-approximation of the set of reachable states using sample executions and discrepancy functions. Using the reachability computation technique, this thesis proposes a safety verification algorithm which is proved to be sound and relatively complete. This technique is implemented in a tool called, Compare-Execute-Check-Engine (C2E2) and experimental results show that it is scalable.

▼ Current regulatory requirements on data privacy make it increasingly important for
enterprises to be able to verify and audit their compliance with their privacy policies. Traditionally, a privacy policy is written in a natural language. Such policies inherit the potential ambiguity, inconsistency and mis-interpretation of natural text. Hence, formal languages are emerging to allow a precise specification of enforceable privacy policies that can be verified.
The EP3P language is one such formal language. An EP3P privacy policy of an enterprise consists of many rules. Given the semantics of the language, there may exist some rules in the ruleset which can never be used, these rules are referred to as redundant rules.
Redundancies adversely affect privacy policies in several ways. Firstly, redundant rules reduce the efficiency of operations on privacy policies. Secondly, they may misdirect the policy auditor when determining the outcome of a policy. Therefore, in order to address these deficiencies it is important to identify and resolve redundancies.
This thesis introduces the concept of minimal privacy policy - a policy that is free of redundancy. The essential component for maintaining the minimality of privacy policies
is to determine the effects of the rules on each other. Hence, redundancy detection and resolution frameworks are proposed. Pair-wise redundancy detection is the central concept in these frameworks and it suggests a pair-wise comparison of the rules in order to detect redundancies. In addition, the thesis introduces a policy management tool that assists policy auditors in performing several operations on an EP3P privacy policy while maintaining its minimality. Formal results comparing alternative notions of redundancy, and how this would affect the tool, are also presented.

▼ La sécurité des systèmes d'information devient un enjeu préoccupant pour les organisations tant publiques que privées, car de tels systèmes sont pour la plupart universellement accessibles à partir de navigateurs Web. Parmi tous les aspects liés à la sécurité des systèmes d'information, c'est celui de la sécurité fonctionnelle qui est étudié dans cette thèse sous l'angle de la mise en œuvre de politiques de contrôle d'accès dans une architecture orientée services. L'élément de base de la solution proposée est un modèle générique qui introduit les concepts essentiels pour la conception de gestionnaires d'exécution de politiques de contrôle d'accès et qui établit une séparation nette entre le système d'information et les mécanismes de contrôle d'accès. L'instanciation de ce modèle conduit à un cadre d'applications qui comporte, entre autres, un filtre de contrôle d'accès dynamique. Cette thèse présente également deux méthodes systématiques d'implémentation de ce filtre à partir de politiques écrites en ASTD, une notation graphique formelle basée sur les statecharts augmentés d'opérateurs d'une algèbre de processus. La notation ASTD est plus expressive que la norme RBAC et ses extensions, la solution actuellement privilégiée dans l'industrie. La première méthode repose sur une transformation de politiques de contrôle d'accès, instanciées à partir de patrons de base exprimés en ASTD, en des processus BPEL. La deuxième méthode est basée sur une interprétation de spécifications ASTD par des processus BPEL. Dans les deux cas, les processus BPEL s'exécutent dans un moteur d'exécution BPEL et interagissent avec le système d'information. Ces deux méthodes permettent une implémentation automatique d'un cadre d'applications à partir de la spécification de départ. Finalement, un prototype a été réalisé pour chacune des deux méthodes afin de montrer leur faisabilité au niveau fonctionnel et de comparer leurs performances au niveau système
Nowadays information systems are, more than ever, available through Web browsers. Therefore, they become vulnerable against attack, which has made security an important issue for public and private organizations. This thesis examines in depth one aspect of information system security, namely functional security through access-control policy enforcement, when such systems are implemented in a service-oriented architecture framework. The foundation of the proposed solution is a generic model that introduces essential concepts to design enforcement managers for access-control policies and clearly separates responsibilities between the information system and access control mechanisms. Instantiation of this model results in a general framework, which encompasses many components including a dynamic access-control filter. This thesis also presents two systematic implementation methods for the dynamic access-control filter from policies expressed in ASTD, a formal and graphical notation based on statecharts enriched with process algebra operators. The ASTD notation is more expressive than the RBAC…

▼ L’objectif de cette thèse est de fournir un modèle, une méthode et un outil d’aide à la réalisation de scénarios interactifs. Cette solution répond au problème de l’opposition entre la maîtrise du déroulement d’un jeu vidéo et son niveau d’interactivité. En d’autres termes, notre but est d’aider à réaliser des jeux vidéo dont l’évolution satisfait les intentions des auteurs tout en autorisant un déroulement influencé par les choix du joueur (exprimés aux travers de ses actions). Pour cela, notre proposition permet à l’utilisateur de produire un modèle de scénario de jeu de bonne qualité qui est : (a) riche – le scénario fournit suffisamment d’options pertinentes aux personnages joueur/non-joueur de sorte que le joueur puisse déterminer le déroulement du jeu et sente toujours que le discours créé est intéressant, (b) valide – tous les discours possibles dans le scénario sont cohérents et répondent aux effets désirés par les auteurs, (c) opérationnel – la représentation du scénario est exécutable. Ce scénario est ensuite employé comme l’entrée d’un système de pilotage de narration interactive assurant le contrôle de la gestion du déroulement du jeu. Par conséquent, l’évolution des jeux, qui sont dirigés par un tel système de pilotage, garantit que l’exécution du jeu respecte les souhaits des auteurs, et en même temps, autorise la liberté des actions du joueur. Pour répondre au problème exposé ci-dessus, nous appuyons notre solution sur un modèle mathématique calculable (la logique linéaire) qui offre des mécanismes de déductions rigoureux et automatiques.Nous avons fait un tour d'horizon des approches existantes concernant le pilotage de narration interactive et la validation de scénario. Ceci nous permet d'identifier les principes nécessaires à notre solution, tels que les éléments d'architecture d'un système de pilotage ; la construction,la représentation, l'exécution de scénarios narratifs ; les propriétés de narration importantes ; l'évolution de référence des paramètres dramatiques ; la structuration de discours ; la stratégie pour la validation d'un scénario ; les informations qualitatives et statistiques nécessaires… Nos contributions portent (1) sur la définition d'un ensemble de propriétés de narration spécifiant la qualité des scénarios de jeu ; (2) sur la proposition de modèles, algorithmes et outils pour écrire des modèles de scénario respectant ces propriétés. Nous validons nos résultats par la réalisation de deux exemples. Le premier est un extrait d'un jeu éducatif expliquant comment appliquer notre outil en vue de produire un modèle de scénario de jeu valide, qui est exprimé par un séquent de logique linéaire dont la représentation est conforme à un métamodèle du calcul des séquents. Pour le second exemple, nous décrivons le processus de production complet d'un jeu vidéo réel basé sur l'histoire « Le Petit Chaperon rouge », mettant en oeuvre un prototype de système de pilotage que nous avons proposé, ce qui permet de dérouler le jeu selon le scénario valide produit, donc son évolution satisfait les…
