    This paper evaluates the dynamic aspects of the UML in the context of inter-organizational workflows. Two evaluation methodologies are used. The first one is ontological and is based on the BWW (Bunge-Wand-Weber) models. The second validation is based on prototyping and consists in the development of a workflow management system in the aerospace industry. Both convergent and divergent results are found from the two validations. Possible enhancements to the UML formalism are suggested from the convergent results. On the other hand, the divergent results suggest the need for a contextual specification in the BWW models. Ce travail consiste en une Ă©valuation des aspects dynamiques du language UML dans un contexte de workflow inter-organisationnel. Le choix du language par rapport Ă  d'autres est motivĂ© par sa richesse grammaticale lui offrant une trĂšs bonne adaptation Ă  ce contexte. L'Ă©valuation se fait par une validation ontologique basĂ©e sur les modĂšles BWW (Bunge-Wand-Weber) et par la rĂ©alisation d'un prototype de systĂšme de gestion de workflows inter-organisationnels. À partir des rĂ©sultats convergents obtenus des deux diffĂ©rentes analyses, des amĂ©liorations au formalisme UML sont suggĂ©rĂ©es. D'un autre cotĂ©, les analyses divergentes suggĂšrent une possibilitĂ© de spĂ©cifier les modĂšles BWW Ă  des contextes plus particuliers tels que ceux des workflows et permettent Ă©galement de suggĂ©rer d'autres amĂ©liorations possibles au langage.Ontology, Conceptual study, Prototype Validation, UML, IS development methods and tools., Ontologie, Ă©tude conceptuelle, validation du prototype, UML, mĂ©thodes et outils de dĂ©veloppement IS

    A Framework for Evaluating Model-Driven Self-adaptive Software Systems

    Get PDF
    In the last few years, Model Driven Development (MDD), Component-based Software Development (CBSD), and context-oriented software have become interesting alternatives for the design and construction of self-adaptive software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the modularity, flexibility, adaptability, and reliability of software systems. An analysis of these technologies shows them all to include the principle of the separation of concerns, and their further integration is a key factor to obtaining high-quality and self-adaptable software systems. Each technology identifies different concerns and deals with them separately in order to specify the design of the self-adaptive applications, and, at the same time, support software with adaptability and context-awareness. This research studies the development methodologies that employ the principles of model-driven development in building self-adaptive software systems. To this aim, this article proposes an evaluation framework for analysing and evaluating the features of model-driven approaches and their ability to support software with self-adaptability and dependability in highly dynamic contextual environment. Such evaluation framework can facilitate the software developers on selecting a development methodology that suits their software requirements and reduces the development effort of building self-adaptive software systems. This study highlights the major drawbacks of the propped model-driven approaches in the related works, and emphasise on considering the volatile aspects of self-adaptive software in the analysis, design and implementation phases of the development methodologies. In addition, we argue that the development methodologies should leave the selection of modelling languages and modelling tools to the software developers.Comment: model-driven architecture, COP, AOP, component composition, self-adaptive application, context oriented software developmen

    Legal compliance by design (LCbD) and through design (LCtD) : preliminary survey

    Get PDF
    1st Workshop on Technologies for Regulatory Compliance co-located with the 30th International Conference on Legal Knowledge and Information Systems (JURIX 2017). The purpose of this paper is twofold: (i) carrying out a preliminary survey of the literature and research projects on Compliance by Design (CbD); and (ii) clarifying the double process of (a) extending business managing techniques to other regulatory fields, and (b) converging trends in legal theory, legal technology and Artificial Intelligence. The paper highlights the connections and differences we found across different domains and proposals. We distinguish three different policydriven types of CbD: (i) business, (ii) regulatory, (iii) and legal. The recent deployment of ethical views, and the implementation of general principles of privacy and data protection lead to the conclusion that, in order to appropriately define legal compliance, Compliance through Design (CtD) should be differentiated from CbD

    Querying a regulatory model for compliant building design audit

    Get PDF
    The ingredients for an effective automated audit of a building design include a BIM model containing the design information, an electronic regulatory knowledge model, and a practical method of processing these computerised representations. There have been numerous approaches to computer-aided compliance audit in the AEC/FM domain over the last four decades, but none has yet evolved into a practical solution. One reason is that they have all been isolated attempts that lack any form of standardisation. The current research project therefore focuses on using an open standard regulatory knowledge and BIM representations in conjunction with open standard executable compliant design workflows to automate the compliance audit process. This paper provides an overview of different approaches to access information from a regulatory model representation. The paper then describes the use of a purpose-built high-level domain specific query language to extract regulatory information as part of the effort to automate manual design procedures for compliance audit

    Towards a Semantic-based Approach for Modeling Regulatory Documents in Building Industry

    Regulations in the Building Industry are becoming increasingly complex and involve more than one technical area. They cover products, components and project implementation. They also play an important role to ensure the quality of a building, and to minimize its environmental impact. In this paper, we are particularly interested in the modeling of the regulatory constraints derived from the Technical Guides issued by CSTB and used to validate Technical Assessments. We first describe our approach for modeling regulatory constraints in the SBVR language, and formalizing them in the SPARQL language. Second, we describe how we model the processes of compliance checking described in the CSTB Technical Guides. Third, we show how we implement these processes to assist industrials in drafting Technical Documents in order to acquire a Technical Assessment; a compliance report is automatically generated to explain the compliance or noncompliance of this Technical Documents

    Regulatory Compliance-oriented Impediments and Associated Effort Estimation Metrics in Requirements Engineering for Contractual Systems Engineering Projects

    Get PDF
    Large-scale contractual systems engineering projects often need to comply with a myriad of government regulations and standards as part of contractual fulfillment. A key activity in the requirements engineering (RE) process for such a project is to elicit appropriate requirements from the regulations and standards that apply to the target system. However, there are impediments in achieving compliance due to such factors as: the voluminous contract and its high-level specifications, large number of regulatory documents, and multiple domains of the system. Little empirical research has been conducted on developing a shared understanding of the compliance-oriented complexities involved in such projects, and identifying and developing RE support (such as processes, tools, metrics, and methods) to improve overall performance for compliance projects. Through three studies on an industrial RE project, we investigated a number of issues in RE concerning compliance, leading to the following novel results:(i) a meta-model that captures artefacts-types and their compliance-oriented inter-relationships that exist in RE for contractual systems engineering projects; (ii) discovery of key impediments to requirements-compliance due to: (a) contractual complexities (e.g., regulatory requirements specified non-contiguously with non-regulatory requirements in the contract at the ratio of 1:19), (b) complexities in regulatory documents (e.g., over 300 regulatory documents being relevant to the subject system), and (c) large and complex system (e.g., 40% of the contractual regulatory requirements are cross-cutting); (iii) a method for deriving base metrics for estimating the effort needed to do compliance work during RE and demonstrate how a set of derived metrics can be used to create an effort estimation model for such work; (iv) a framework for structuring diverse regulatory documents and requirements for global product developments. These results lay a foundation in RE research on compliance issues with anticipation for its impact in real-world projects and in RE research

    Developing a GIS-Database and Risk Index for Potentially Polluting Marine Sites

    Get PDF
    The increasing availability of geospatial marine data provides an opportunity for hydrographic offices to contribute to the identification of “Potentially Polluting Marine Sites” (PPMS). These include shipwrecks, oil rigs, pipelines, and dumping areas. To adequately assess the environmental risk of these sites, relevant information must be collected and converted into a multi-scale geodatabase suitable for site inventory and geo-spatial analysis. In addition, a Risk Index – representing an assessment of the magnitude of risk associated with any site – can be derived to determine the potential impacts of these PPMS. However, the successful collection and integration of PPMS information requires some effort to ‘normalize’ and standardize the data based on recognized international standards. In particular, there is benefit in structuring the data in conformance with the Universal Hydrographic Data Model (IHO S-100) recently adopted by the International Hydrographic Organization. In this paper, an S-100 compliant product specification for a PPMS geo-spatial database and associated Marine Site Risk Index is proposed which can be used by national hydrographic offices and marine protection agencies

    Conceptual Modeling in Law: An Interdisciplinary Research Agenda

    Get PDF
    The article describes how different approaches from the IS field of conceptual modeling should be transferred to the legal domain to enhance comprehensibility of legal regulations and contracts. It is further described how this in turn would benefit the IS discipline. The findings emphasize the importance of further interdisciplinary research on that topic. A research agenda that synthesizes the presented ideas is proposed based on a framework that structures the research field. Researchers from both disciplines, IS and Law, that are interested in this field should use the research agenda to position their research and to derive new and innovative research questions
