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.

Description Framework

In the process of information semantic integration for product design and manufacturing, it is very important to express the product information semantic. Description logics (DLs) are a family of state-of-the-art knowledge representation languages, and a decidable subset of first-order logic. Firstly, by analyzing the characteristics of product information, proposed a semantic information description framework based on description logics for product information integration, which is divided into three levels: basic description logic, classic extended logic and unusual extended logic. Then, in the framework, reducer was taken for example to illustrate the application of their description logic in product design and manufacturing formal semantic information. Finally, based on description logic, discussed reasoning problems of product design and manufacturing information.

System A

With recent advances in wireless communication technologies, the world of mobile computing is flourishing with a variety of applications. This paper presents a mobile product information retrieval system that supports collaborative work among remote users. With the development of the system, a knowledge representation framework has been adopted which accommodates semantic relationships and similarity of product data. To illustrate the system developed, a case study in information retrieval for product design is presented．

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.

The existing process equipment design resource utilization rate in automobile industry is low, so it is urgent to change the design method to improve the design efficiency. This paper proposed a fast design method of process equipment driven by classification retrieval of 3D model-based definition (MBD). Firstly, an information integration 3D model is established to fully express the product information definition and to effectively express the design characteristics of the existing 3D model. Through the classification machine-learning algorithm of 3D MBD model based on Extreme Learning Machine (ELM), the 3D MBD model with similar characteristics to the auto part model to be designed was retrieved from the complex process equipment case database. Secondly, the classification and retrieval of the model are realized, and the process equipment of retrieval association mapping with 3D MBD model is called out. The existing process equipment model is adjusted and modified to complete the rapid design of the process equipment of the product to be designed. Finally, a corresponding process equipment design system was developed and verified through a case study. The application of machine learning to the design of industrial equipment greatly shortens the development cycle of equipment. In the design system, the system learns from engineers, making them understand the design better than engineers. Therefore, it can help any user to quickly design 3D models of complex products.
