    This paper presents a deep investigation and an interdisciplinary analysis of the collaborative networked enterprise engineering issues and modelling approaches related to the relevant aspects of the semantic web technology and knowledge strategies. The paper also suggests a novel framework based on ontology metamodelling, knowledge model discovery, and semantic web infrastructures, architectures, languages, and systems. The main aim of the research enclosed in this paper is to bridge the gaps between enterprise engineering, modelling, and especially networking by intensively applying semantic web technology based on ontology conceptual representations and knowledge discovery. The ontological modelling approaches together with knowledge strategies such as discovery (data mining) have become promising for future enterprise computing systems. The related reported research deals with the conceptual definition of a semantic-driven framework and a manufacturing enterprise metamodel (ME_M) using ontology, knowledge-driven object models, standards, and architectural approaches applied to collaborative networked enterprises. The conceptual semantic framework and related issues discussed in this paper may contribute towards new approaches of enterprise systems engineering and networking as well as applied standard and referenced ontological models

    Focus Issue on Legacy Information Systems and Business Process Change:Modelling of Organisational Change Using the EKD Framework

    Little attention has been given in the development of a systematic approach for elaborating and using enterprise knowledge to manage organisational change. In this paper we present a framework based on the confluence of two technologies: enterprise knowledge modelling and process guidance. The framework comprises of a set of modelling components for describing intentional enterprise knowledge, and a number of strategies for reasoning with enterprise knowledge during organisational change projects. Dynamic selection of appropriate strategies is guided by the use of a methodology roadmap. The approach is demonstrated using examples from an industrial application of change resulting from de-regulation in the electricity supply sector

    Enterprise knowledge modelling: Domains and aspects

    Get PDF
    The paper presents the Knowledge‐based Enterprise framework aimed for the analysis of knowledge management and development of an Enterprise knowledge base. The approaches concerning the modelling of enterprise domains and aspects are presented and used for the development of the concept of Enterprise Knowledge Component. The Enterprise knowledge component (B, T, K) is defined as a composition of 3 obligatory parts: knowledge management methods (K), the knowledge about IT (T) services and tools, and business management knowledge (B). The formal modelling structure – the Enterprise Knowledge Space (B, T, K) is constructed for the refinement of the hierarchy of enterprise knowledge items. The Knowledge‐based Enterprise framework is represented as modified Value Chain Model including the knowledge management layer and IT component. The major knowledge subsets of the enterprise knowledge base are identified.

    COEL: A Web-based Chemistry Simulation Framework

    Get PDF
    The chemical reaction network (CRN) is a widely used formalism to describe macroscopic behavior of chemical systems. Available tools for CRN modelling and simulation require local access, installation, and often involve local file storage, which is susceptible to loss, lacks searchable structure, and does not support concurrency. Furthermore, simulations are often single-threaded, and user interfaces are non-trivial to use. Therefore there are significant hurdles to conducting efficient and collaborative chemical research. In this paper, we introduce a new enterprise chemistry simulation framework, COEL, which addresses these issues. COEL is the first web-based framework of its kind. A visually pleasing and intuitive user interface, simulations that run on a large computational grid, reliable database storage, and transactional services make COEL ideal for collaborative research and education. COEL's most prominent features include ODE-based simulations of chemical reaction networks and multicompartment reaction networks, with rich options for user interactions with those networks. COEL provides DNA-strand displacement transformations and visualization (and is to our knowledge the first CRN framework to do so), GA optimization of rate constants, expression validation, an application-wide plotting engine, and SBML/Octave/Matlab export. We also present an overview of the underlying software and technologies employed and describe the main architectural decisions driving our development. COEL is available at http://coel-sim.org for selected research teams only. We plan to provide a part of COEL's functionality to the general public in the near future.Comment: 23 pages, 12 figures, 1 tabl

    Towards the development of the framework for inter sensing enterprise architecture

    Full text link
    [EN] Inter-enterprise architecture (IEA) is a new concept that seeks to apply the tools and methodologies of enterprise architecture (EA) in a collaborative context, in order to model collaborative organizations in an inclusive manner. According to the main enterprise architectures proposed to this point, an EA should be conformed at least for a framework, a methodology and a modelling language. Sensing enterprise (SE) is an attribute of an enterprise or a network that allows it to react to business stimuli originating on the Internet. These fields have come into focus recently, and there is not evidence of the use of IEA for modelling a SE, while finding an interesting gap to work on. Thus, this paper proposes an initial framework for inter sensing enterprise architecture (FISEA), which seeks to classify, organize, store and communicate, at the conceptual level, all the elements for inter-sensing enterprise architectures and their relationships, ensuring their consistency and integrity. This FISEA provides a clear idea about the elements and views that create collaborative network and their inter-relationships, based on the support of Future Internet.This work was supported by the European Commission FP7 UNITE Project, through its Secondment Programme and the Universitat Politecnica de Valencia ADENPRO-PJP project (ref.

    Enterprise modelling in support of methods based engineering: lean implementation in an SME

    Get PDF
    Popular ‘methods-based’ approaches to engineering enterprises include: BPR, Continuous Improvement, Kaizen, TQM, JIT, Lean and Agile Manufacturing. Generally the industrial application of such methods-based approaches leads to long lead-times, high costs, and poorly justified engineering projects that do not prepare the organization for future change. These outcomes are to be expected because (1) invariably Manufacturing Enterprises (MEs) constitute very complex and dynamic systems that naturally require complex design and change processes and (2) current methods-based approaches to organizational design and change are not analytically well founded. Therefore the authors argue that a framework and modelling toolset are required to facilitate ongoing and integrated application of methods-based engineering approaches, providing underlying modelling structures and concepts to ‘systemize’ and ‘quantify’ key aspects of organization design and change. Unless suitable decomposition, quantitative and qualitative modelling principles are used to underpin an approach such as a Lean Manufacturing, deficiencies will remain. Often, MEs adopt the “we need be lean” mindset without holistic understandings of causal and temporal impacts of such philosophies on ME processes, resource systems and current and possible future workflows. Enterprise Modelling (EM) partially addresses the aforementioned problems and can support the development of robust understandings about current enterprise processes and potential capabilities of systems. However in general, current EM techniques are geared best to capturing and organizing relatively enduring knowledge and data about any given organization but are themselves deficient in respect to replicating and predicting dynamic system behaviors. This paper presents a model driven approach to organization design and change in support of methods-based engineering, applying Lean Manufacturing principles, with a UK based bearing manufacturer. EM and various derivative Simulation Modelling (SM) views were generated to display system behaviors under changing scenarios

    A goal-oriented requirements modelling language for enterprise architecture

    Get PDF
    Methods for enterprise architecture, such as TOGAF, acknowledge the importance of requirements engineering in the development of enterprise architectures. Modelling support is needed to specify, document, communicate and reason about goals and requirements. Current modelling techniques for enterprise architecture focus on the products, services, processes and applications of an enterprise. In addition, techniques may be provided to describe structured requirements lists and use cases. Little support is available however for modelling the underlying motivation of enterprise architectures in terms of stakeholder concerns and the high-level goals that address these concerns. This paper describes a language that supports the modelling of this motivation. The definition of the language is based on existing work on high-level goal and requirements modelling and is aligned with an existing standard for enterprise modelling: the ArchiMate language. Furthermore, the paper illustrates how enterprise architecture can benefit from analysis techniques in the requirements domain

    Ontology-based patterns for the integration of business processes and enterprise application architectures

    Get PDF
    Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data. Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their applicability in business process-driven application integration is demonstrated

    Enterprise engineering using semantic technologies

    Modern Enterprises are facing unprecedented challenges in every aspect of their businesses: from marketing research, invention of products, prototyping, production, sales to billing. Innovation is the key to enhancing enterprise performances and knowledge is the main driving force in creating innovation. The identification and effective management of valuable knowledge, however, remains an illusive topic. Knowledge management (KM) techniques, such as enterprise process modelling, have long been recognised for their value and practiced as part of normal business. There are plentiful of KM techniques. However, what is still lacking is a holistic KM approach that enables one to fully connect KM efforts with existing business knowledge and practices already in IT systems, such as organisational memories. To address this problem, we present an integrated three-dimensional KM approach that supports innovative semantics technologies. Its automated formal methods allow us to tap into modern business practices and capitalise on existing knowledge. It closes the knowledge management cycle with user feedback loops. Since we are making use of reliable existing knowledge and methods, new knowledge can be extracted with less effort comparing with another method where new information has to be created from scratch
