Conceptual modelling of a concurrent engineering environment (original) (raw)

ENVIROMENT MODELLING FOR CONCURRENT ENGINEERING

International Journal of …, 2000

The research and development in the area of computer integrated construction have looked at various fragments of the domain to be used as a glue for the integration of the profession. Examples of these fragments include products and processes. In this paper, environment modelling is suggested, as an approach that provides a more complete picture of the domain requires the support of information technology. An environment-modelling framework is proposed, which decomposes an abstract concurrent engineering environment into several modelling spaces. F or practical reasons, two-dimensional orthogonal framework decomposition is used. Along the first axis, the framework is decomposed according to the modelling aspect (construction, information system, generic), and along the second axis according to the level of detail (neutral, aspect, application). In this paper, we present the decomposition criteria, the resulting framework, and some essential components of the environment. Reported is the work in progress accomplished as a part of the European Union's ESPRIT project ToCEE.

Intelligent concurrent engineering environment

Computers & Industrial Engineering, 1993

Thoughseveral are the in-roads that have been made towards achieving design-for-manufacturability(DFM) and design-forassembly (DFA), speaking of some of the crucial issues associated with concurrent engineering, yet very few comprehensive blueprints exist that speak of a near-complete concurrent engineering environment. This could mainly be attributed to the multifarious versions of how to successfully setup a concurrent engineering environment for today's ever changing engineering scenario. An operational concurrent engineering environment needs to be addressed in its totality or near-totality. This paper is one such venture.

An Information Sharing Platform for Concurrent Engineering

Integrated Manufacturing Systems Engineering, 1995

Research is currently being undertaken by several research laboratories into the computer aided support of simultaneous engineering. These support systems aim to assist organisations that have adopted the simultaneous engineering philosophy by providing consistent sources of product and manufacturing information, and by providing access to a diversity of applications that support decision making.

A concurrent engineering-oriented design database representation model

Computer-Aided Design, 2004

A concurrent engineering-oriented design database representation model (CE-DDRM) is introduced in this research for supporting various life-cycle aspects in concurrent design. In this model, concepts and behaviors of different design database modeling components, including entities, properties, relationships, tasks, and specifications, are defined at meta-class level. Design database is modeled at two different levels, class level and instance level, representing generic design libraries and special design cases, respectively. A Web-based system architecture is proposed to model distributed design database and allow team-members for different product development life-cycle aspects at different locations to access the design database. This newly introduced approach provides the foundation for developing the next generation CAD systems with concurrent engineering functions. q

A Framework for Concurrent Engineering - ToCEE

2000

Before examining requirements to extend previously created integrated environmen engineering, it is worth considering what is meant by this term. From concurrent engineering research in other domains we have the following definitions: 路 In Winner et al. (1988) concurrent engineering is defined as "a systematic approach to the integrated, concurrent design of products and their related processes, including manufacturing and

Projection-based knowledge representation for concurrent engineering

1995 IEEE International Conference on Systems, Man and Cybernetics. Intelligent Systems for the 21st Century, 1995

This paper describes an integrative approach to represent knowledge structures and entities in the concurrent engineering enterprise. General types of knowledge are classified and presented in various perspectives and abstractions. A new concept of knowledge representation based on projections is introduced. It is demonstrated how the projection concept integrates various facets of CE. Conclusions discuss the benefits of the proposed representation scheme and discuss potential application scenarios.

A Software Architecture for Concurrent Lifecycle Design and Construction

The application of computing technologies to civil/structural engineering has grown phenomenally over the past few decades. It is safe to say therefore, that the time has now come for the advancements made to date in such technologies, to be applied to the overall spectrum of the design process within AEC companies. This paper hence sets the scene for a futuristic outlook into an integrated software framework to support the lifecycle activities involved in AEC construction projects. The paper discusses inter-alia, a model for such an integrated environment as well as the requirements to be addressed in the implementation of the software architecture It then concludes with a description of the proposed software architecture within the paradigm of Concurrent Lifecycle Design and Construction.

Product Development and Concurrent Engineering

SpringerReference

Concurrent engineering facilities (CEFs) are successfully used in the aeropsace sector to design systems and services that that fulfill the requirements. Model-based systems engineering (MBSE) enables the effective (i.e., unambiguous) communication in the collaborative activities within concurrent engineering and service systems engineering facilities. The advantages obtained by the MBSE approach can be further scaled up by an innovative approach that take into explicit account the representation of the inter-systems aspects, i.e., those aspects, namely interfaces, that stay in between the system, its subsystems and external entities (other systems and organizations). Such an approach, briefly denoted as a Model-based Interface Engineering (MBIE), brings several benefits to the CEF activities. This paper illustrates the integration of the Interface Communication Modelling Language (ICML) into the existing MBSE methods for the CEF software framework VirSat, by identifying the business needs driving the use of MBIE approaches and showing example application scenarios. concept/design that fulfills the system requirements, in a timeframe that ususally spans over two or three weeks. In such a context, the advantages obtained by the MBSE approach, in terms of enhanced communications, reduced development risks, improved quality, increased productivity and enhanced knowledge transfer, can be further scaled up by innovative approaches that take into explicit account the representation of the inter-systems aspects, i.e., those aspects, namely interfaces, that stay in between the

A PRODUCT MODEL BASED ARCHITECTURE FOR ENGINEERING APPLICATIONS SOFTWARE

2000

Some progress has been made in the establishment of agreed product models as the basis of a more open information-centric approach to engineering processes, both in the construction sector and beyond. Specific construction related initiatives, such as the CIS, the IFC and AP225 have been implemented in software and are now beginning to impact on industry. In common with other engineering sectors, these standards have drawn heavily on ISO 10303 (STEP), particularly the EXPRESS data definition language.
