Reducing the "Information Gap" Between Synchronous and Asynchronous Co-operative Design Phases
This paper aims to describe a particular role of annotations as co-operative artefacts in engineering design. In co-operative processes, where achieving a shared understanding between the participants from different domains is crucial, sharing the decisions and argumentations which lead to a solution is as important as sharing the solution itself. In our case study, we describe what we call an "information gap" between the asynchronous phase, when individual decisions are made, and the design review, when the solution is evaluated, and collective thinking influences the decisions. Then, within a conceptual design scenario, we show how semantic annotations can create a shared environment to help to reduce this gap, where all actors are able to elicit domain-specific constraints and engage discussions on design solution during the asynchronous phase.semantic annotation; engineering design; design communication; collaborative tool
Lifecycle Information Systems: the concept, principles and an approach
The aim of this article is to introduce the concept of lifecycle information systems (LCISs), in which the main purpose is to permit the development of ISs capable of supporting the management of information of an entity during its whole lifecycle. In order to validate this concept, we outline the MyHistory which consists in an experimental IS structured in four different contexts, supporting the information management of persons during their lifecycle. As the main contribution, this article introduces a new approach for the development of ISs which can improve the current way of information management of entities
ADAPTS: An Intelligent Sustainable Conceptual Framework for Engineering Projects
This paper presents a conceptual framework for the optimization of environmental sustainability in engineering projects, both for products and industrial facilities or processes. The main objective of this work is to propose a conceptual framework to help researchers to approach optimization under the criteria of sustainability of engineering projects, making use of current Machine Learning techniques. For the development of this conceptual framework, a bibliographic search has been carried out on the Web of Science. From the selected documents and through a hermeneutic procedure the texts have been analyzed and the conceptual framework has been carried out. A graphic representation pyramid shape is shown to clearly define the variables of the proposed conceptual framework and their relationships. The conceptual framework consists of 5 dimensions; its acronym is ADAPTS. In the base are: (1) the Application to which it is intended, (2) the available DAta, (3) the APproach under which it is operated, and (4) the machine learning Tool used. At the top of the pyramid, (5) the necessary Sensing. A study case is proposed to show its applicability. This work is part of a broader line of research, in terms of optimization under sustainability criteria.TelefĂłnica Chair âIntelligence in Networksâ of the University of Seville (Spain
Project-based collaborative engineering learning to develop Industry 4.0 skills within a PLM framework
Training and learning methods for engineering students, in the disciplines of product design and manufacturing, are becoming more difficult and complex since they have to integrate theoretical technical knowledge, skills in computer-aided applications (CAx) and skills in collaborative work practices. Product Lifecycle Management (PLM) tools support structured collaborative practices and CAx supports engineering content creation. Both types of software applications are key in the Industry 4.0 development. They also evolve over time, incorporate new functionalities, and change their graphical user interface (GUI), adding complexity to the learning process. Traditionally, engineering education addresses the learning of CAx and PLM tools separately, hindering a holistic learning experience to the students. This communication presents a structured integrated vision of these tools and their learning. Project-Based Learning (PBL) is proposed as a learning approach suitable to provide a learning experience that facilitates the development of Industry 4.0 skills and competences
A hyperconnected manufacturing collaboration system using the semantic web and Hadoop ecosystem system
With the explosive growth of digital data communications in synergistic operating networks and cloud computing service, hyperconnected
manufacturing collaboration systems face the challenges of extracting, processing, and analyzing data from multiple distributed web sources.
Although semantic web technologies provide the solution to web data interoperability by storing the semantic web standard in relational
databases for processing and analyzing of web-accessible heterogeneous digital data, web data storage and retrieval via the predefined schema
of relational / SQL databases has become increasingly inefficient with the advent of big data. In response to this problem, the Hadoop
Ecosystem System is being adopted to reduce the complexity of moving data to and from the big data cloud platform. This paper proposes a
novel approach in a set of the Hadoop tools for information integration and interoperability across hyperconnected manufacturing collaboration
systems. In the Hadoop approach, data is âExtractedâ from the web sources, âLoadedâ into a set of the NoSQL Hadoop Database (HBase)
tables, and then âTransformedâ and integrated into the desired format model with Hive's schema-on-read. A case study was conducted to
illustrate that the Hadoop Extract-Load-Transform (ELT) approach for the syntax and semantics web data integration could be adopted across
the global smartphone value chain
An environment to support negotiation and contracting in collaborative networks
During the last years, manufacturing and service industries faced a global change in the production paradigm. They have to continuously adapt their operating principles in reaction to new business or collaboration opportunities, where a natural reaction is a shift to a new business paradigm with the creation of strategic alliances for product or services development, but also for innovative and emergent business services design. On one hand, the process of creating such alliances can be rather simple if organizations share the same geographical and cultural context.
But on the other hand, considering different conditions, there might be a low success rate in the creation of successful consortia. One known reason for such low rate are the delays resulting from negotiations in the establishment of collaboration commitments, represented by contracts or agreements, which are crucial in the creation of such alliances.
The collaborative networks discipline covers the study of networks of organizations
specially when supported by computer networks. This thesis contributes with research in this field describing the creation process of virtual organizations, and proposing a negotiation support environment to help participants in the negotiation of the consortia creation process and in the co-design of new business services. A negotiation support environment is therefore proposed and described with its main requirements, adopted negotiation protocol, conceptual architecture, models, and software environment.
To demonstrate the feasibility of the implementation of the proposed systems, a proof-ofconcept software prototype was implemented and tested using some specific scenarios. This thesis work has been validated adopting a methodology that includes: (i) validation in the research community; (ii) validation in a solar industry network; and (iii) validation by comparison analysis
The Digital Transformation of Automotive Businesses: THREE ARTEFACTS TO SUPPORT DIGITAL SERVICE PROVISION AND INNOVATION
Digitalisation and increasing competitive pressure drive original equipment manufacturers (OEMs) to switch their focus towards the provision of digital services and open-up towards increased collaboration and customer integration. This shift implies a significant transformational change from product to product-service providers, where OEMs realign themselves within strategic, business and procedural dimensions.
Thus, OEMs must manage digital transformation (DT) processes in order to stay competitive and remain adaptable to changing customer demands. However, OEMs aspiring to become participants or leaders in their domain, struggle to initiate activities as there is a lack of applicable instruments that can guide and support them during this process. Compared to the practical importance of DT, empirical studies are not comprehensive.
This study proposes three artefacts, validated within case companies that intend to support automotive OEMs in digital service provisioning. Artefact one, a layered conceptual model for a digital automotive ecosystem, was developed by means of 26 expert interviews. It can serve as a useful instrument for decision makers to strategically plan and outline digital ecosystems. Artefact two is a conceptual reference framework for automotive service systems. The artefact was developed based on an extensive literature review, and the mapping of the business model canvas to the service system domain. The artefact intends to assist OEMs in the efficient conception of digital services under consideration of relevant stakeholders and the necessary infrastructures. Finally, artefact three proposes a methodology by which to transform software readiness assessment processes to fit into the agile software development approach with consideration of the existing operational infrastructure.
Overall, the findings contribute to the empirical body of knowledge about the digital transformation of manufacturing industries. The results suggest value creation for digital automotive services occurs in networks among interdependent stakeholders in which customers play an integral role during the servicesâ life-cycle. The findings further indicate the artefacts as being useful instruments, however, success is dependent on the integration and collaboration of all contributing departments.:Table of Contents
