A web-based collaborative design advisory system for designing micro products is being developed, which is based on use of both knowledge and rules. The system is aimed at helping designers to assess/optimise the design of micro products to be manufactured with micro-forming. The Microsoft C# programming language, ASP.Net technique and Microsoft Access database system have been used to develop this system. The system is composed of various assessment modules such as product geometry features, forming processes, materials, machines, tools and cost assessment modules. Clients can use/browse the user interface of the integrated system through the internet to import a CAD design model and define design parameters. The system is not only able to assess the client’s design but also to generate preliminary process plans for the selected micro-forming processes. A micro-pin design is used as an example to test the capability of the 1st prototype system. With such a system, some advantages such as increasing the design efficiency in the web-based collaborative design environment have been identified.

Definition Of

Numerous collaborative design tools have been developed to accelerate the product development, and recently environments for building distributed simulations have been proposed. For example, a simulation framework called DOME (Distributed Object-oriented Modeling and Evaluation) has been developed in MIT CADLAB. DOME is unique in its decentralized structure that allows heterogeneous simulations to be stitched together while allowing proprietary information an simulation models to remain secure with each participant. While such an approach offers many advantages, it also hides causality and sensitivity information, making it difficult for designers to understand problem structure and verify solutions. The purpose of this research is to analyze the relationships between design parameters (causality) and the strength of the relationships (sensitivity) in decentralized web-based design simulation. Algorithms and implementations for the causality and sensitivity analysis are introduced. Causality is determined using Granger’s definition of causality, which is to distinguish causation from association using conditional variance of the suspected output variable. Sensitivity is estimated by linear regression analysis and a perturbation method, which transfers the problem into a frequency domain by generating periodic perturbations. Varying Internet latency and disturbances are problematic issues with these methods. Thus, new algorithms are developed and tested to overcome these problems.

Abstract In this paper, we discuss a distributed collaborative design for embodying concurrent engineering. The concept of a process-centric collaborative design is proposed to progress collaboratively an engineering design. It is implemented in the PEDWorks (Process-centric Engineering Design Workspace) as a prototype system for the Web-based collaborative workspace to integrate design activities in a distributed and heterogeneous computing environment. The PEDWorks has a client/server architecture, which consists of server applications such as a process controller, a design board, a communication server and a CAD server, and the client browsers with a Web-based process-driven user interface. We have conformed to CORBA (Common Object Request Broker Architecture) standard to support interoperability between distributed objects and have used JAVA to support cross-platform and distributed user access to PEDWorks on the Web. PEDWorks enables design teams to define the design process collaboratively, execute it in a distributed environment, share design information and communicate with each other.

This paper presents a case study on the collaboration between a set of distributed web applications developed and deployed for carrying out a 'Design for Assembly' analysis. The case study is conducted using a web-based prototype system called CyberCO. The system is based on a theoretical framework which has been formed through an innovative combination of a number of concepts such as agents and workflows. Unlike previous attempts in computer supported concurrent engineering systems, collaboration in this framework between distributed web applications is achieved through workflows between their representative agents. The flows of data between agents are guided by the associated constraints. The flows of controls are somewhat data-driven in the sense that agents start and stop themselves whenever the predefined conditions are satisfied. The data-driven flows of controls are different from those widely used in workflow management where flows of controls are determined by the precedence relationships. The key purpose of this case study demonstration is to extend our knowledge and insights into this emerging field where increasing number of web applications are developed and deployed for collaborative product development and realization projects.

The rapid development of information technology (IT) has enabled digital services to evolve continually and support a growing number of internet-enabled devices, along with user diversity. The end-user anticipation within the smart environments, which are internet-enabled, delivery networks and innovative technologies. What tools/methods can support the collaborative design and effectively choreograph the design process with dynamic knowledge between service designers and service users? The cooperative design is recognizable in the design environment with a collection wide-ranged by co-design methods and tools. In-depth interviews uncover contextually appropriate design process requirements from diverse stakeholder groups. A collection of design tools and methods are selected and implemented within a Web-based co-design platform. Uncovered design requirements are subsequently applied in extending the Double Diamond framework prior to operationalization into a design process blueprint with supporting service design tool selection as the main contributions for this paper.

Input Model

The tedious process of building an input model and of manual communication between CAD and Finite Element Analysis (FEA) significantly restricts the designers from using FEA, particularly in preliminary design. Most of the previous works concentrate on expediting this process by interfacing CAD and FEA. This paper propose full integration of FEA simulation code within a CAD system, thus several problems are avoided. The section-based FEA is used as better suited to early design. It requires, comparing to the 3-D FEA, development of additional CAD functions to extract appropriate sections from the CAD model. The proposed integrated system allows for rapid use of the FEA and unifies the design environment to avoid inconsistency. It provides a mechanism to specify the part orientation relative to the punch traveling direction to support tipping. It also extracts the geometrical data of a specified section to automatically build and store a FEA input model. The numerical simulation of the process can be then performed without exiting the CAD system. Both existing as well as newly developed CAD functions, needed for the proposed integration system, are presented. The feasibility and advantages of such integration is demonstrated on the developed prototype system.

Collaborative Evaluation

In conceptual design, a number of design concepts and alternatives would be generated. These concepts and alternatives usually need to be evaluated to reduce the search space. However, it is not easy for the designers to determine which alternative is better, especially in the design environment where multiple designers might be involved. Current researches mainly focused on the evaluation models, but rarely provide the integrated tools to assist the evaluation process. To address this problem, we propose a web-based collaborative design evaluation platform and two evaluation principles for different evaluation situations. A design case is used to illustrate the evaluation process, where it is necessary for the designers to select a working phenomenon for the “generate force” subfunction of a nailing machine.

An assemblability evaluation system of products including parts and subassemblies was presented. The necessity about assemblability evaluation for subassemblies was discussed. A subassembly-centered product assemblability analysis method was proposed. The two-step assemblability analysis flow including process step and entire step about subassembly was designed, which can analyze structure of subassembly when it was assembled and fitted on product. A web-based prototype system of subassembly-centered product assimilability evaluation which supports multi-sited collaborative design was developed with Java/JSP, which integrated with the platform of collaborative assembly planning and collaborative assembly simulation. Finally, an example was used to validate reasonability of subassembly assemblability analysis method and the effectiveness of the evaluation system.

The public service administration system at the government offices of the Kemiri village office in the Kemiri District currently does not have a computerized and integrated system. Because the system runs, residents who submit letters for administrative completeness, still use the Ms.Word / Ms.Excel application. of course has many weaknesses including human error, not neat in file storage, resulting in the lengthy process of searching and making a cover letter and required reports. The analytical method used in this study is to use PIECES (Performance, Informance, Economy, Control, Efficiency, Service) analysis, the design of the model uses UML (Unified Modeling Language). The results of this study are web-based letter information systems at the Office of the Village Chief of Kemiri that can accessed using a local computer browser. Thus the information letter needed by the Kemiri Village community and more effective and efficient in making the letter.
