During the past two decades, concurrent or collaborative engineering (CE) has presented new possibilities for successful product
development. In addition, the advances in computer networks and information technology have brought engineering design context
into a new era. As a promising approach to accommodate the radical pace of changes in the context of engineering design, agent
technologies have been attracting public attention and are being used in an increasingly wide variety of applications. However,
little attention has been paid to multi-agent system (MAS) frameworks for CE environments that enable systematic and timely
design integrations in both hierarchical and heterarchical design topology. This is the first of a two-part paper proposing
a MAS framework for integrated product design in a computer network-oriented CE environment. Part I first proposes a hybrid
agent network architecture to develop lightweight, dynamic and large-scale distributed systems, and then proposes a hybrid
agent architecture based on our finite state automata (FSA) formalism that can exhibit both hybrid behaviours and hybrid interactions.
Finally, some ideas for building an integrated product design environment are presented using the proposed agent and network
architecture. Part II discusses the applications of the proposed MAS framework to concurrent engineering design. 相似文献

Concurrent or collaborative engineering (CE) has inspired research in the area of design decomposition, which facilitates
the concurrency of product lifecycle functions from the earlier stage of the product development process and reduces the complexity
of a design problem. The decomposition-based design, on the other hand, necessitates various integration efforts for recombining
the decomposed design problems. This is the second of a two-part paper proposing a multi-agent system (MAS) framework for
integrated product design in a computer network-oriented CE environment. Part II discusses the applications of the proposed
MAS framework to concurrent engineering design. The proposed framework realises the systematic and timely design integrations
between multi-functional/cross-functional team members in a dynamic design environment, by enabling model integration, solution
integration and tool integration. The proposed design agents make the problem-specific engineering models or heterogeneous
design tools interoperable and network-accessible, and also provide the interaction spaces for communicating, integrating
or coordinating the individual design solutions. Throughout the paper, the proposed system is illustrated with a successful
implementation of a continuously variable transmission (CVT) design problem over the Internet . 相似文献

Developing an Integrated Intelligent Framework to Support an Engineering Change Process for an Axial Piston Pump 总被引:2,自引:0,他引:2
C. Ou-Yang C. W. Chang 《The International Journal of Advanced Manufacturing Technology》1999,15(5):345-355
Since the concepts of concurrent engineering were introduced in mid 1980s, the product design process has become complicated.
This is because many factors related to the life cycle of the product may need to be considered during the design stage. Therefore,
shortening product development time becomes important for the survival of an enterprise. In this paper, an integrated intelligent
environment to support concurrent engineering is proposed. Two major modules are provided by this system to assist change
management. One is a constraint network module that analyses the related constraints about a design change to find the design
variables influenced. Another is a product assembly module that extracts the design data from a CAD database to analyse the
spatial relationships relating to an assembly. The data in the above two modules are integrated in a data integrated module,
in which an entity relational data model was developed to describe the integrated data. Finally, a web-based query system
was developed to provide a multiplatform environment for the user to refer to the data in the constraint network module and
the product assembly module during a design change process. The proposed environment is implemented in the design change process
for an axial piston pump. 相似文献

Owing to intricate interdependency and information feedback among tasks, the concurrent design process probably cannot converge
to the correct solution when there are wrong integration and improper interaction between activities. Therefore research on
concurrent design process optimization is necessary. In the paper, a novel methodology is proposed to analyze and optimize
the concurrent engineering process scientifically. Based on design structure matrix and graph theory, coupled task recognition
and design task level plotting are performed for the concurrent design process of aluminum profile extrusion product development.
Three factors are used to describe the coupling property of activity, namely sensitivity, complexity and affection factors,
which provide the basis to analyze development process quantitatively. And an optimism algorithm is presented to define the
initial iteration order of coupled task set. Finally a rational and efficient concurrent design process model is constructed,
which can make aluminum profile product development faster, with lower costs and higher quality. The methodology proposed
is also applicable to other concurrent engineering fields. 相似文献

This paper presents research that establishes a systematic methodology and knowledge base for an injection-molding mold design in a concurrent engineering environment. This methodology is, in general, analogous to the methods of design for manufacturing, and is, however, in collaboration with activities of molding product design and mold manufacturing process planning. The practical goal of this research is twofold: to develop a mold-development process that facilitates concurrent engineering-based practice and to develop a knowledge-based design aid for injection-molding mold design that accommodates manufacturability concerns, as well as requirements of products. The research approach includes (i) process modeling and reengineering for concurrent mold design, (ii) identification of functional requirements with a computer-based system, (iii) system framework design, and (iv) system modeling and implementation. The framework supports concurrent engineering based mold design by providing advisory tools that are able to resolve relevant issues at the early stages of mold design. The results of this research will facilitate the rationalization and automation of the mold development process, thus improving the efficiency and quality of, and reducing the cost of, mold development. 相似文献

An intelligent system based on concurrent engineering for innovative product design at the conceptual design stage 总被引:2,自引:1,他引:1

This paper describes the development of an intelligent system based on concurrent engineering for generating design alternatives at the conceptual design stage. The proposed system encompasses a design analysis module, a design evaluation module, a knowledge acquisition and storing module, a user interface and databases. It is also integrated with a spreadsheet application for storing data and numerical analysis and works in combination with a material selection software Cambridge engineering selector (CES) to facilitate the material selection process. The tangible advantage of implementing this system is that it enables the designer to explore and experiment with alternative ideas in the early design stage, and it results in design solutions that are functionally sound- and cost-effective. It also has the capability for design alternatives evaluation, material selection and modelling the product detailed design on the computer-aided design system. Therefore, an efficient product development process is generated. Three case studies are demonstrated and discussed to validate the proposed system. 相似文献

A comparison of approaches to concurrent engineering 总被引:1,自引:1,他引:1
Dr. Shad Dowlatshahi 《The International Journal of Advanced Manufacturing Technology》1994,9(2):106-113
In this paper, various approaches to the successful implementation of concurrent engineering are presented. Approach 1 addresses the information and software requirements of an integrated manufacturing information system. Two sets of data requirements for the design of mechanical products are discussed. Approach 2 uses feature based design as the impetus behind CAD/CAM integration. A conceptual framework leading to the development of a knowledge-based management system (KBMS) is proposed. KBMS is capable of representing multiple and concurrent views of features. Approach 3 considers product design concerns from inception to disposal in a unified life cycle engineering (ULCE) environment. Approach 4 focuses on assembly as an integrative function of all manufacturing activities. Approach 5 emphasises organisational and cultural issues and proposes that effective dialogue between design and manufacturing engineers is essential for abandoning the over-the-wall design concept. In conclusion, a critique of various approaches to concurrent engineering is provided. 相似文献

Although extensive research has been carried out in the area of tolerancing techniques for product design, concurrent engineering is still very seldom used in this context. This paper introduces a unique tolerancing method which applies the concept of concurrent engineering. The proposed method essentially allocates the required functional assembly tolerances to the component tolerances by formulating the tolerancing problem into a mathematical model and solving the model using a linear programming approach. The component tolerances are first represented in terms of the process tolerances, assigned by process planners at an early stage of the product design. The objective function of the mathematical model, which is to maximise the residual tolerances of the processes, is then established and the constraints formulated based on the assembly requirements and process constraints. The model is subsequently solved using a linear programming approach. Finally, the proposed method is tested on a practical example. 相似文献

Contemporary computer-based design tools are not suitable for concurrent engineering oriented product design due to (a) their particular and stand-alone functionality, (b) the lack of a capability to support interactive decision-making, and (c) the heavy involvement of designer expertise and experience. This paper presents a feature-based design for a manufacturing framework which is able to support the practice of concurrent engineering by providing functions designed specifically for net shape product design and on-line design guidance. Knowledge-based and object-oriented modeling technologies are employed to develop design evaluation facilities. An object-oriented product model, embedded with product design and process knowledge, is constructed and used for design evaluation. Geometric reasoning is performed on features, feature interactions, and overall shape to identify areas that may conflict with design principles. This paper concentrates on design for net shape manufacturing with an emphasis on die casting and injection molding processes. However, the proposed framework is general enough for other net shape processes by customizing process specific features and encoding process design rules. 相似文献

This paper presents a cyber design for manufacturing (DFM) framework for concurrent material and process selections. An internet-of-things (IoT) interface is developed wherein design, material, and process databases are accessed in a cloud-based environment. Digital designs are processed to extract dimensional features and functional requirements. A Node-RED IoT simulator is developed to provide seamless interconnectivity to translate design specifications with material and process databases via web sockets. The output from the cloud system is incorporated within a decision-making algorithm. The analytical hierarchy process (AHP) is implemented where alternatives are hierarchically compared to generate weights based on combinatorial order ranking of the designer preferences. A material-process index (MPI) is developed that integrates the material and process generated weights with material-process compatibility for selecting the optimal material and process combination. The proposed methodology is applied to an electrical power distribution interchangeable fuse cutout system to validate the approach. Material and processes are selected on a standalone basis without considering their compatibilities. Further, the MPI function is implemented that integrates functional preferences for material, process, and their compatibilities to contrast against standalone material and process selections. The material-process combination with the highest MPI was chosen as the optimal solution for a product design. The cyber DFM methodology developed in this research can be extended to different application domains based on flexible user chosen criteria. 相似文献

A visualization system for integrating maintainability design and evaluation at product design stage
Gaoliang Peng Xin Hou Jun Gao Debin Cheng 《The International Journal of Advanced Manufacturing Technology》2012,61(1-4):269-284
Thoughtful consideration of products maintenance features early in design stage can reduce or eliminate maintenance costs, reduce downtime, and improve safety. As such, the effective collaboration of product designers and maintenance technicians throughout the product design process is becoming much more important for the most advanced competitiveness. To address this need, a visualization system that enables maintainability-related technicians cooperated with product designers in a networked manufacturing environment is proposed in this study. This paper presents a systematic approach to implementation of a Web-based visualization system by using virtual reality technology. The system aims at providing a simulated environment and concurrent engineering processes to facilitate communication, coordination, control, and integration of product maintainability validation and improvement activities. The result of this research will help increase product maintainability, reduce development cycle time and cost, and hence increase product marketability. 相似文献
