    Detecting Functional Requirements Inconsistencies within Multi-teams Projects Framed into a Model-based Web Methodology

    One of the most essential processes within the software project life cycle is the REP (Requirements Engineering Process) because it allows specifying the software product requirements. This specification should be as consistent as possible because it allows estimating in a suitable manner the effort required to obtain the final product. REP is complex in itself, but this complexity is greatly increased in big, distributed and heterogeneous projects with multiple analyst teams and high integration between functional modules. This paper presents an approach for the systematic conciliation of functional requirements in big projects dealing with a web model-based approach and how this approach may be implemented in the context of the NDT (Navigational Development Techniques): a web methodology. This paper also describes the empirical evaluation in the CALIPSOneo project by analyzing the improvements obtained with our approach.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED

    Agent-based modeling: a systematic assessment of use cases and requirements for enhancing pharmaceutical research and development productivity.

    A crisis continues to brew within the pharmaceutical research and development (R&D) enterprise: productivity continues declining as costs rise, despite ongoing, often dramatic scientific and technical advances. To reverse this trend, we offer various suggestions for both the expansion and broader adoption of modeling and simulation (M&S) methods. We suggest strategies and scenarios intended to enable new M&S use cases that directly engage R&D knowledge generation and build actionable mechanistic insight, thereby opening the door to enhanced productivity. What M&S requirements must be satisfied to access and open the door, and begin reversing the productivity decline? Can current methods and tools fulfill the requirements, or are new methods necessary? We draw on the relevant, recent literature to provide and explore answers. In so doing, we identify essential, key roles for agent-based and other methods. We assemble a list of requirements necessary for M&S to meet the diverse needs distilled from a collection of research, review, and opinion articles. We argue that to realize its full potential, M&S should be actualized within a larger information technology framework--a dynamic knowledge repository--wherein models of various types execute, evolve, and increase in accuracy over time. We offer some details of the issues that must be addressed for such a repository to accrue the capabilities needed to reverse the productivity decline

    Patterns of information security postures for socio-technical systems and systems-of-systems

    Get PDF
    This paper describes a proposal to develop patterns of security postures for computer based socio-technical systems and systems-of-systems. Such systems typically span many organisational boundaries, integrating multiple computer systems, infrastructures and organisational processes. The paper describes the motivation for the proposed work, and our approach to the development, specification, integration and validation of security patterns for socio-technical and system-of-system scale systems

    Modelling iteration in engineering design

    Get PDF
    This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of each perspective depends upon domain-specific factors. Key challenges of modelling iteration in process simulation frameworks such as the Design Structure Matrix are discussed, and we argue that no single model or framework can fully capture the iterative dynamics of an NPD process. To conclude, we propose that consideration of iteration and its representation could help identify the most appropriate modelling framework for a given process and modelling objective, thereby improving the fidelity of design process simulation models and increasing their utility

    A practical approach to product design for future worlds using scenario-development

    Get PDF
    The focus of consumer product design is shifting from primarily offering functionality, towards\ud experience and emotion driven product characteristics [1]. At the same time the functioning of\ud products is more and more defined in its social context. Product designers can play a major role in\ud developing our future social context, as long as they are aware of the responsibility towards users,\ud society and environment. In the master ‘Design & Styling’ of the Industrial Design Engineering\ud program of the University of Twente, we created a course “Create the Future”, addressing both these\ud future- and society oriented aspects of design. In this paper we describe the course structure and the\ud associated teaching methods, give examples of student results and discuss the points of interest and\ud application possibilities. In the 2008 edition the students explored the future of food. First the students\ud created a future context by investigating, building and visualizing multiple scenarios. Subsequently\ud they designed a future product concept within these scenario contexts. It showed that the structure of\ud this course was particularly suitable for designing products for the not so near future, i.e. 15-20 years\ud ahead. Especially scenario development proved to be a good instrument for the students to be able to\ud create a tangible context for designing future products and services

    Reconciling Actors' Preferences in Agricultural Policy - Towards a New Management of Public Decisions

    Get PDF
    To attain sustainable development in the 21st century, the world's population still has to overcome many challenges; hunger, poverty, environmental degradation and depletion. Policy design in such a context is and will remain a complex task. On one hand, policy makers often lack information on stakeholders' strategies and constraints as well as on potential options for improvement. On the other hand, stakeholders do not always adhere to policies for lack of understanding of the pursued goals. It is not unusual to observe that often, real policy effects are not those initially expected. Furthermore, existing decision-making mechanisms for public intervention are increasingly questioned due to pressure for market liberalization, decentralization processes and the increasing role of the civil society. However, while the classical role of government is challenged, few methods have been proposed to enable the design of viable alternatives. The approach presented in this book is a contribution to the improvement of efficiency in public decision-making. Based on practical experience from Viet Nam, Indonesia and other countries, it proposes new methods for the identification of policy objective, stakeholders and issues at stake, and for the definition and implementation of concrete actions. It also provides means and guidance to foster progressive actors' participation and involvement in decision-making and policy implementation processes.
