We present a developed Web-based product design and manufacturing system that supports collaborative Concurrent Engineering. It models distributed systems and databases using Web technologies, so that these distributed system and databases can be accessed anywhere in the world. In such system, product developers can exchange and share product data, communicate with other team members, modify geometry data on particular aspects of the design and maintain operations consistency in all the distributed cooperative sites on a wide variety of platforms. The new system is a Client/Server architecture. The server manages the sharing of the common model, as well as the coordination among multiple users, in which different users can modify different parts of the shared model. In addition, the server supports many client through the Internet, and it also allows peer to peer negotiation, sharing different databases located in different machines, establishing relations between them at run time. A group of users can work together in a common single write mode, which continuously synchronized with the master copy on the central server. The proposal model is producing a new manner and has many algorithms for viewing, editing, synchronizing, and collaboration coordination. It utilizes Java 3D to view 3D CAD files in interactive manner. It introduces an intelligent user interface for editing and modification. STEP, which is international standard introduced by the International Standards Organization (ISO), is used to exchange engineering information. Java Server Page (JSP) is used for Collaboration coordination and semantic-based coordination.

Use Of Internet

Abstract Although Concurrent Engineering can offer substantial benefits, and hence many companies take a strong interest in the collaborative approach, it is not yet clear how it can best be implemented, particularly for a geographically distributed Concurrent Engineering team that may be using a disparate range of computer systems. The recent rise in the number connected to the Internet would offer the possibility of using Internet standards to allow for collaboration over the Internet. Central to the use of Internet standards for Concurrent Engineering is the key area of transmitting and viewing CAD and engineering information, and of communication between team members. This paper is concerned with addressing this issue and describes the how 3D CAD files can be viewed, and engineering information exchanged, by geographically distributed team members in an interactive manner using Internet standards. In particular this paper is concerned with the issue of storing STEP data so that it can be retrieved efficiently, how this data can be converted from STEP data to the Virtual Reality Modeling Language (VRML) to allow the product to be viewed in interactive 3-D on a wide number of platforms using the Internet, and is concerned with the issue of how team members can markup the VRML worlds, with other team members being able to examine the markup comments of others. An algorithm for converting STEP data to VRML is described and an overview of the implementation of this approach, in a system called CyberView, is given. The result of this is that users from disparate functions, on a wide variety of platforms, can view products in interactive 3-D through the Internet, can comment on aspects of the design, and can examine the markup comments of other team members on particular aspects of the design. Such an approach offers the promise of improved communication and hence for enhancing the product development process.

Outstanding Issue

Abstract The shared usage of computer tools among members of a design team heavily relies on the interoperability of the systems involved. Interoperability is an outstanding issue in engineering information management science for more than twenty years, and is held responsible for a multi-billion economical loss yearly in industry. Efforts (STEP, IGES) by standardization bodies and by the software industry, which now deliver web-based platforms such as Corba and Java, can only superficially address the interoperability problem. Most of the solutions come down to giving clients long fingers to remotely control a centralized model. It is generally recognized that such a centralized approach is far from efficient. However, when the design tasks are really distributed among the team members, a rock bottom limitation invariably emerges, thus canceling most of the potential gain in efficiency. In this paper the interoperability is formally defined. It is then shown why and under which conditions interoperability is deemed to fail. The prime purpose of the paper is to promote awareness about this issue among researchers and infrastructure designers. Once being aware of the fundamental constraints of interoperability, compromise solutions may be intentionally developed, rather than to implement ad hoc work-around procedures (which are responsible the bulk of the financial loss mentioned). We present an approach to systematically analyze and model the requirements of a shared infrastructure, and to anticipate the feasibility of interoperability.

User Friendly

Concurrent Engineering (CE) considers a product design and manufacturing simultaneously. The CE research has led to the product information integration. However, the current CE research focuses on smooth of the product information flow rather than a user-friendly searching process for users to obtain product information quickly. A new data retrieval system for product design and manufacturing is proposed in this paper. The system not only provides an integrated product database, but also uses Virtual Reality (VR) and Web technologies for easing navigation in product data and for accelerating access to useful information. The effective collaboration in a product design and manufacturing can be achieved through the proposed information searching method. Examples are presented in the discussion.

Web-based Code Management System (WCMS) is an essential tool for realizing information exchange in distant collaborative product design and manufacturing among global-based enterprises. A framework for WCMS is built up on a three-tier client/server system and the WCMS is developed utilizing JAVA and J2EE technologies. The developed WCMS mainly uses servlets and JSP to handle user inputs and manage and retrieve code data from the database through the JDBC driver, with the server components stored on a middleware program called Tomcat. The WCMS developed in this work has been successfully implemented in an enterprise.

Quality function deployment (QFD) is an essential tool in implementing total quality management (TQM). This study applies a Web-QFD approach using group decision-making analysis in the Web environment to reduce the complicated data collection, aggregation and analysis processes. A Web-based questionnaire is designed by using an active service pages (ASP) involving the Internet relay chat (IRC) technique and the Delphi method with Internet (E-Delphi) to determine the importance degree of the customers' requirements. However, the traditional Delphi method is time-consuming mission. This study applies the proposed Web-QFD approach to efficiently gather the individual opinions of each team member, the requirements that are critical for customers, and then enables decision makers to accurately assess the priorities of these requirements. An empirical example of an education system in Taiwan is employed to demonstrate the practicability of the proposed Web-QFD model. This real world example involves team members communicating easily and quickly with other experts in the team through the Internet to accelerate the reaching of a consensus among multiple decision makers regardless of where their location. Customers' requirements can be rapidly prioritized based on the assessment results.
