    To address the challenges in the automotive industry posed by the need to rapidly manufacture more product variants, and the resultant need for more adaptable production systems, radical changes are now required in the way in which such systems are developed and implemented. In this context, two enabling approaches for achieving more agile manufacturing, namely modular automation systems and virtual commissioning, are briefly reviewed in this contribution. Ongoing research conducted at Loughborough University which aims to provide a modular approach to automation systems design coupled with a virtual engineering toolset for the (re)configuration of such manufacturing automation systems is reported. The problems faced in the virtual commissioning of modular automation systems are outlined. AutomationML - an emerging neutral data format which has potential to address integration problems is discussed. The paper proposes and illustrates a collaborative framework in which AutomationML is adopted for the data exchange and data representation of related models to enable efficient open virtual prototype construction and virtual commissioning of modular automation systems. A case study is provided to show how to create the data model based on AutomationML for describing a modular automation system

    The use of Building Information Management (BIM) has become mainstream in many countries. Exchanging data in open standards like the Industry Foundation Classes (IFC) is seen as the only workable solution for collaboration. To define information needs for collaboration, many organizations are now documenting what kind of data they need for their purposes. Currently practitioners define their requirements often a) in a format that cannot be read by a computer; b) by creating their own definitions that are not shared. This paper proposes a bottom up solution for the definition of new building concepts a property. The authors have created a prototype implementation and will elaborate on the capturing of information specifications in the future

    Mirroring or misting: On the role of product architecture, product complexity, and the rate of product component change

    Get PDF
    This paper contributes to the literature on the within-firm and across-firm mirroring hypothesis – the assumed architectural mapping between firms’ strategic choices of product architecture and firm architecture, and between firms’ architectural choices and the industry structures that emerge. Empirical evidence is both limited and mixed and there is evidently a need for a more nuanced theory that embeds not only whether the mirroring hypothesis holds, but under what product architecture and component-level conditions it may or may not hold. We invoke an industrial economics perspective to develop a stylised product architecture typology and hypothesise how the combined effects of product architecture type, product complexity and the rate of product component change may be associated with phases of mirroring or misting. Our framework helps to reconcile much existing mixed evidence and provides the foundation for further empirical research

    This is the post-print version of the Article. The official published version can be obtained from the link below - Copyright @ 2011 InderscienceThis paper presents the intermediate results of the Learning Network on Sustainability (LeNS) project, Asian-European multi-polar network for curricula development on Design for Sustainability. LeNS is a mechanism to develop and diffuse system design for sustainability in design schools with a transcultural perspective. The main output of the project is the Open Learning E-Package (OLEP), an open web-platform that allows a decentralised and collaborative production and fruition of knowledge. Apart from the contents, the same LeNS web-platform is realised in an open-source and copy left ethos, allowing its download and reconfiguration in relation to specific needs, interests and geographical representation

    Computationally efficient induction of classification rules with the PMCRI and J-PMCRI frameworks

    In order to gain knowledge from large databases, scalable data mining technologies are needed. Data are captured on a large scale and thus databases are increasing at a fast pace. This leads to the utilisation of parallel computing technologies in order to cope with large amounts of data. In the area of classiïŹcation rule induction, parallelisation of classiïŹcation rules has focused on the divide and conquer approach, also known as the Top Down Induction of Decision Trees (TDIDT). An alternative approach to classiïŹcation rule induction is separate and conquer which has only recently been in the focus of parallelisation. This work introduces and evaluates empirically a framework for the parallel induction of classiïŹcation rules, generated by members of the Prism family of algorithms. All members of the Prism family of algorithms follow the separate and conquer approach.are increasing at a fast pace.

    Interoperability and Standards: The Way for Innovative Design in Networked Working Environments

    Organised by: Cranfield UniversityIn today’s networked economy, strategic business partnerships and outsourcing has become the dominant paradigm where companies focus on core competencies and skills, as creative design, manufacturing, or selling. However, achieving seamless interoperability is an ongoing challenge these networks are facing, due to their distributed and heterogeneous nature. Part of the solution relies on adoption of standards for design and product data representation, but for sectors predominantly characterized by SMEs, such as the furniture sector, implementations need to be tailored to reduce costs. This paper recommends a set of best practices for the fast adoption of the ISO funStep standard modules and presents a framework that enables the usage of visualization data as a way to reduce costs in manufacturing and electronic catalogue design.Mori Seiki – The Machine Tool Compan

    Enabling Machine Understandable Exchange of Energy Consumption Information in Intelligent Domotic Environments

    In the 21st century, all the major countries around the world are coming together to reduce the impact of energy generation and consumption on the global environment. Energy conservation and its efficient usage has become a top agenda on the desks of many governments. In the last decade, the drive to make homes automated and to deliver a better assisted living picked pace and the research into home automation systems accelerated, usually based on a centralized residential gateway. However most devised solutions fail to provide users with information about power consumption of different house appliances. The ability to collect power consumption information can lead us to have a more energy efficient society. The goal addressed in this paper is to enable residential gateways to provide the energy consumption information, in a machine understandable format, to support third party applications and services. To reach this goal, we propose a Semantic Energy Information Publishing Framework. The proposed framework publishes, for different appliances in the house, their power consumption information and other properties, in a machine understandable format. Appliance properties are exposed according to the existing semantic modeling supported by residential gateways, while instantaneous power consumption is modeled through a new modular Energy Profile ontolog

    A new ethos for a multipolar design learning community: A mechanism for the development and diffusion of teaching materials on design for sustainability in an open-source and copy left ethos

    Copyright @ 2010 International Association of Technology, Education and DevelopmentFinally, the time has arrived in which there is a shared opinion that sustainable development requires a system discontinuity, meaning that radical changes in the way we produce, consume and socially interacts are needed. Finally, the time has arrived in which there is an emerging understanding that an important contribution to this change can be directly linked to the role of the design. However we have to admit that the designers are still more part of the problem, than part of the solution, i.e. proactive and diffused actors of the radical change requested by the transition towards a sustainable society. Within the so called learning society, new visions and tools are urgently requested for the design. A new political agenda is needed, looking at all of the of the design’s bodies (the designers, the design educators and the design researchers) as a learning community that urgently needs to accelerate the process of consolidation and diffusion of the new knowledge and know-how, for a new generation of designers. Under this perspective, a key role should be played by the design schools. The paper will explore this issue and in its framework presents the vision, the ambitions and the tools developed within the Learning Network on Sustainability (LeNS) project, an Asian- European multi-polar network for curricula development on Design for Sustainability, financed by the European Commission under the Asia-Links programme

    Semantic query languages for knowledge-based web services in a construction context

    Since the early 2000s, different frameworks were set up to enable web-based collaboration in building projects. Unfortunately, none of these initiatives was granted a long life. Recently, however, the use of web technologies in the building industry has been gaining momentum again, considered some promising technologies for reaching a more interoperable BIM practice. Specifically, this relates to (1) Linked Data and Semantic Web technologies, and (2) cloud-based applications. In order to combine these into a network of interlinked applications and datastores, an agreed-upon mechanism for automatic communication and data retrieval needs to be used. Apart from the W3C standard SPARQL, often considered too high a threshold for developers to implement, there are some recent GraphQL-based solutions that simplify the querying process and its implementation into web services. In this paper, we review two recent open source technologies based on GraphQL, that enable to query Linked Data on the web: GraphQL-LD and HyperGraphQL
