    Towards the Automated Qualification of Tool Chain Design2012In: SAFECOMP 2012 Workshops: Sassur, ASCoMS, DESEC4LCCI, ERCIM/EWICS, IWDE, Magdeburg, Germany, September 25-28, 2012, Proceedings, Springer Berlin/Heidelberg, 2012, 392-399 p.Conference paper (Refereed)
    Abstract [en]

    The development of safety-critical embedded systems is supported by a number of development tools, which are increasingly integrated into automated tool chains. Safety standards require these tool chains to be qualified, which is costly and requires a large effort. To reduce cost and effort tool chains can be composed of pre-qualified tools and then themselves pre-qualified by identifying the parts of tool chain software that have an impact on safety more exactly. In this paper we propose the use of a modeling language to describe this tool chain composition. This allows us to reduce effort even further by automatically analyzing the tool chain model for safety issues. It also promises to reduce the effort and cost of later steps in the deployment of the tool chain by formalizing the communication of safety issues and automating the generation of code for tool chain software.

    A Domain Specific Language for Generating Tool Integration Solutions2011Conference paper (Other academic)
    Abstract [en]

    Model-based development of complex systems requires toolsupport for the dierent phases of the system life cycle. To allow for anecient development process, the involved tools need to be integrated.Despite the availability of modern tool integration platforms and frameworks,it is complex, labor-intensive and costly to build tool integrationsolutions. For managing the growing complexity of tool integration solutions,a need for systematic engineering arises. A missing piece is thehigh-level architectural description of tool integration solutions. We proposethe domain specic language TIL for describing tool integrationsolutions at a high level of abstraction. We propose an approach thattakes advantage of modeling technologies to systematize and automatethe process of building tool integration solutions. By automatically generatingintegration solutions from a TIL model, we can reduce the manualimplementation eort.

    On the modeling and generation of service-oriented tool chains2014In: Software and Systems Modeling, ISSN 1619-1366, E-ISSN 1619-1374, Vol. 13, no 2, 461-480 p.Article in journal (Refereed)
    Abstract [en]

    Tool chains have grown from ad-hoc solutions to complex software systems, which often have a service-oriented architecture. With service-oriented tool integration, development tools are made available as services, which can be orchestrated to form tool chains. Due to the increasing sophistication and size of tool chains, there is a need for a systematic development approach for service-oriented tool chains. We propose a domain-specific modeling language (DSML) that allows us to describe the tool chain on an appropriate level of abstraction. We present how this language supports three activities when developing service-oriented tool chains: communication, design and realization. A generative approach supports the realization of the tool chain using the service component architecture. We present experiences from an industrial case study, which applies the DSML to support the creation of a service-oriented tool chain. We evaluate the approach both qualitatively and quantitatively by comparing it with a traditional development approach.

    Model-based Service Discovery and Orchestration for OSLC Services in Tool Chains2012In: Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics): Volume 7387 LNCS, 2012, 283-290 p.Conference paper (Refereed)
    Abstract [en]

    Globally distributed development of complex systems relies on the use of sophisticated development tools but today the tools provide only limited possibilities for integration into seamless tool chains. If development tools could be integrated, development data could be exchanged and tracing across remotely located tools would be possible and would increase the efficiency of globally distributed development. We use a domain specific modeling language to describe tool chains as models on a high level of abstraction. We use model-driven technology to synthesize the implementation of a service-oriented wrapper for each development tool based on OSLC (Open Services for Lifecyle Collaboration) and the orchestration of the services exposed by development tools. The wrapper exposes both tool data and functionality as web services, enabling platform independent tool integration. The orchestration allows us to discover remote tools via their service wrapper, integrate them and check the correctness of the orchestration.

    Automated Construction of Data Integration Solutions for Tool Chains2012In: ICSEA 2012 : The Seventh International Conference on Software Engineering Advances, 2012, 102-111 p.Conference paper (Refereed)
    Abstract [en]

    Modern software development relies increasingly on the orchestrated use of development tools in the form of seamless, automated tool chains. Tool chains are becoming complex software systems themselves, however, the efficient development of tool chains is a largely unsupported, manual engineering task. We propose both a domain specific modeling language for systematically specifying tool chains and generators for efficiently realizing the tool chain as software. Tool chain software consists of diverse components, such as service-oriented applications, models and model transformations, which we produce by different generative techniques. We study both the separate generative techniques and the dependencies between the generated artifacts to ensure that they can be integrated. We evaluate the approach both quantitatively and qualitatively, and show in a case study that the approach is practically applicable when building a tool chain for industrially relevant tools.

    A Roadmap Towards Integrated CPS Development Environments2013Conference paper (Refereed)
    Abstract [en]

    Cyber Physical System (CPS) development is highly heterogeneous, involving many stakeholders, each of which interacts with its development artifacts through a variety of tools, and within several engineering processes. Successful CPS development requires these tools to be well-integrated into a Development Environment (DE) in order to support its many stakeholders and processes. In this paper we identify the main challenges facing DE development for CPSs, and presents a roadmap to meet these challenges. We here take the position that focus should be redirected from trying to achieve a single, one-size-fits-all solution to such a heterogeneous problem. Instead, focus should be placed on supporting the development of highly-customized DEs, which readily can be applied to industrial development. Such a highly-customized DE should fit the needs of a particular development organization, while at the same time taking advantage of relevant standardization efforts.

    Modelling Support for a Linked Data Approach to Tool Interoperability2016In: The Second International Conference on Big Data, Small Data, Linked Data and Open Data, ALLDATA, Lisbon, February 21 - 25, 2016., 2016, 42-47 p.Conference paper (Refereed)
    Abstract [en]

    Linked Data is increasingly being adopted for the integration of software tools, especially with the emergence of the Open Services for Lifecycle Collaboration (OSLC) standard on tool interoperability. In this paper, we present a modelling approach – with accompanying tool support – for the specification of Linked Data resources, focusing on the particular needs of tool-chain development. The approach provides graphical models for the specification of constraints on resources being shared in the tool-chain. Moreover, it aims to maintain a centralized understanding and management of the overall information model being handled in the federated tool-chain architecture. This is achieved through an integrated set of modelling views that cover the early phases of tool-chain development.

    Visual Analytics Towards Tool Interoperabilty: A Position Paper2016In: Proceedings of the 11th Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, SCITEPRESS , 2016, 141-147 p.Conference paper (Refereed)
    Abstract [en]

    Complex-engineering projects include artefacts from several engineering disciplines such as mechanical, electrical, software components, processes and plans. While software tools can be powerful in each individual discipline, it is difficult to build integrated tool chains. Moreover, it is challenging to evaluate and update existing tool chains. At the same time, the field of visualization is getting mature and visual analytics promises an opportunity to develop knowledge, methods, technologies and practice for exploiting and combining the strengths of human and data. We consider this as a potential to evaluate current tool chains. This position paper discusses the visualization and visual analytics practices to assess existing tool chains performance.

    Flex-eWare: a flexible model driven solution for designing and implementing embedded distributed systems2012In: Software, practice & experience, ISSN 0038-0644, E-ISSN 1097-024X, Vol. 42, no 12, 1467-1494 p.Article in journal (Refereed)
    Abstract [en]

    The complexity of modern embedded systems increases as they incorporate new concerns such as distribution and mobility. These new features need to be considered as early as possible in the software development life cycle. Model driven engineering promotes an intensive use of models and is now widely seen as a solution to master the development of complex systems such as embedded ones. Component-based software engineering is another major trend that gains acceptance in the embedded world because of its properties such as reuse, modularity, and flexibility. This article proposes the Flex-eWare component model (FCM) for designing and implementing modern embedded systems. The FCM unifies model driven engineering and component-based software engineering and has been evaluated in several application domains with different requirements: wireless sensor networks, distributed client/server applications, and control systems for electrical devices. This approach highlights a new concept: flexibility points that arise at several stages of the development process, that is, in the model (design phase), in the execution platform, and during the execution itself. This flexibility points are captured with model libraries that can extend the FCM.

    A Model-driven and Tool-integration Framework for Whole Vehicle Co-simulation Environments2016Conference paper (Refereed)
    Abstract [en]

    Throughout the design of automotive vehicle systems, modeling and simulation technologies have been widely used for supporting their conceptualization and evaluation. Due to the increasing complexity of such systems, the overall quality management and design process optimization are becoming more important. This in particular brings the necessity of integrating various domain-specific physical models that are traditionally based on different formalisms and isolated tools. In this paper, we present the initial concepts towards a model-driven tool-integration framework with automated managed simulation services in the system development. We exploit EAST-ADL and some other existing state-of-the-art modeling technologies as the reference frameworks for a formal system description, with the content includingrequirements, design solutions, extra-functional constraints, and verification and validation cases. Given such a formal specification, dedicated co-simulation services will be developed to provide the support for automated configuration and execution of simulation tools.

    Software engineering of component-based systems-of-systems: a reference framework2011In: CompArch'11 - Proceedings of the 2011 Federated Events on Component-Based Software Engineering and Software Architecture - CBSE'11, New York, NY, USA: ACM Press, 2011, 61-65 p.Conference paper (Refereed)
    Abstract [en]

    Systems-of-Systems (SoS) are complex infrastructures, which are characterized by a wide diversity of technologies and requirements imposed by the domain(s) they target. In this context, the software engineering community has been focusing on assisting the developers by providing them domain-specific languages, component-based software engineering frameworks and tools to leverage on the design and the development of such systems. However, the adoption of such approaches often prevents developers from combining several domains, which is a strong requirement in the context of SoS. Furthermore, only little attention has been paid to the definition of a modular toolset and an extensible runtime infrastructure for deploying and executing SoS. In this paper, we therefore propose a reference framework to leverage on the software engineering of SoS. Our reference framework has been validated on the development of two platforms, namely Hulotte and FraSCAti, to demonstrate that the resulting complexity is isolated in the core toolset, while the development of domain-specific extensions is leveraged and simplified by clearly identified abstractions.

    Multi-Viewed Components2013Report (Other academic)
    Abstract [en]

    In this report, we present a concept for generic multi-viewed component models based on modular  and (de)composable viewpoints.   By decomposing systems not only along component but also viewpoint borders, a family of multi-viewed component models is proposed. Semantic relations between the viewpoints are modeled in order to be able to ensure e.g. consistency between separate but semantically partly  overlapping views.  We also characterize different types of relations between viewpoints in order to see how the choice of viewpoints in the component model influences the complexity of multi-viewed components. Finally we provide an example and describe how the concepts presented can be applied in practice.

    Component-Oriented Development for Real-Time Java2012In: Distributed, Embedded and Real-time Java Systems / [ed] Higuera-Toledano, T.; Wellings, A., Springer Berlin/Heidelberg, 2012, 265-292 p.Chapter in book (Other academic)
    Abstract [en]

    The Real-Time Specification for Java (RTSJ) offers developers an attrac- tive platform for development of software that is composed of variously stringent real-time and non real-time tasks. However, the RTSJ introduces a programming model involving several non-intuitive rules and restrictions which make systems modeling and development a complex and error-prone task. In this chapter we intro- duce an advanced software engineering technology that allows developers to address these challenges – component-oriented development. In the first part, we present the general concepts and identify the key benefits of this technology. We further show one of the possible approaches on how to embrace this technology when mitigating the complexities of RTSJ development – the Hulotte framework. The framework provides a continuum between the component-oriented design and implementation process of RTSJ systems. The RTSJ concepts are treated as first-class entities which enables the modeling and automatized preparation of their implementation by employing code-generation techniques. We conclude this chapter with an extensive case study comparing object-oriented and component-oriented implementation of the Collision Detector Benchmark. Our empirical evaluation shows that the performance overhead of the framework is minimal in comparison to manually written object-oriented applications without imposing any restrictions on the programming style.

    Optimizing Sensor Network Reprogramming via In Situ Reconfigurable Components2013In: ACM Transactions on Sensor Networks, ISSN 1550-4859, Vol. 9, no 2, 14- p.Article in journal (Refereed)
    Abstract [en]

    Wireless reprogramming of sensor nodes is a critical requirement in long-lived wireless sensor networks (WSNs) addressing several concerns, such as fixing bugs, upgrading the operating system and applications, and adapting applications behavior according to the physical environment. In such resource-poor platforms, the ability to efficiently delimit and reconfigure the necessary portion of sensor software-instead of updating the full binary image-is of vital importance. However, most existing approaches in this field have not been adopted widely to date due to the extensive use of WSN resources or lack of generality. In this article, we therefore consider WSN programming models and runtime reconfiguration models as two interrelated factors and we present an integrated approach for addressing efficient reprogramming in WSNs. The middleware solution we propose, REMOWARE, is characterized by mitigating the cost of post-deployment software updates on sensor nodes via the notion of in situ reconfigurability and providing a component-based programming abstraction in order to facilitate the development of dynamic WSN applications. Our evaluation results show that REMOWARE imposes a very low energy overhead in code distribution and component reconfiguration and consumes approximately 6% of the total code memory on a TELOSB sensor platform.

    A Generic Component-based Approach for Programming, Composing and Tuning Sensor Software2011In: Computer journal, ISSN 0010-4620, E-ISSN 1460-2067, Vol. 54, no 8, 1248-1266 p.Article in journal (Refereed)
    Abstract [en]

    Wireless Sensor Networks (WSNs) are being extensively deployed today in various monitoring and control applications by enabling rapid deployments at low cost and with high flexibility. However, high-level software development is still one of the major challenges to wide-spread WSN adoption. The success of high- level programming approaches in WSNs is heavily dependent on factors like ease of programming, code well-structuring, degree of code reusability, required software development effort, and the ability to tune the sensor software for a particular application. Component-based programming has been recognized as an effective approach to satisfy such requirements. However, most of the componentization efforts in WSNs were ineffective due to various reasons, such as high resource demand or limited scope of use. In this article, we present Remora, a novel component-based approach to overcome the hurdles of WSN software implementation and configuration. Remora offers a well-structured programming paradigm that fits very well with resource limitations of embedded systems, including WSNs. Furthermore, the special attention to event handling in Remora makes our proposal more practical for embedded applications, which are inherently event-driven. More importantly, the mutualism between Remora and underlying system software promises a new direction towards separation of concerns in WSNs. This feature also offers a practical way to develop sensor middleware services which should be generic and developed close to the operating system. Additionally, it allows the customization of sensor software—deploying only application-required system-level services on nodes, instead of installing a fixed large system software image for any application. Our evaluation results show that the deployed Remora applications have an acceptable memory overhead and a negligible CPU cost compared to the state-of-the-art development models.

    Integrating viewpoints in the development of mechatronic products2014In: Mechatronics (Oxford), ISSN 0957-4158, Vol. 24, no 7, 745-762 p.Article in journal (Refereed)
    Abstract [en]

    The development of mechatronic products involves multiple stakeholders which have different viewpoints and therefore use different concepts, models and tools to deal with their concerns of interest. This paper argues that an increased emphasis needs to be placed on the relations between viewpoints to be able to deal with the evolving scope and requirements on mechatronic products. We study relations between viewpoints at the levels of people, models and tools, and present solutions that are used to formally and explicitly capture such relations. Viewpoint contracts are used to define the vocabulary, assumptions and constraints required for ensuring smooth communication between stakeholders (people level). Dependency models capture relations between product properties belonging to different viewpoints, and how such dependencies relate to predictions and decisions (model level). Tool integration models describe the relations between tools in terms of traceability, data exchange, invocation and notifications (tool level). A major contribution of this paper is a unification approach, elaborating how these solutions can be used synergetically to integrate viewpoints. An industrial robot case study is utilized to illustrate the challenges and solutions with respect to relations between viewpoints, including the unification approach.
