The Research On Some Key Technology Of Web-based Product Design Information Filter

With the rapid development of information technology, computer technology and network technology, the process of the world economy's globalization has been accelerated greatly. If an enterprise in competition want be invincible, it must shorten its product development cycle and manufacturing cycle, improve its product performance, reducing costs, so make it enable new products enter market as soon as possible, and thereby gaining the initiative in competition.Product information is the design carriers. With the way of designing changes, the method in the traditional product design process can not meet modern design requirements at the exchange of information and sharing of the means of production. Traditional design methods have been encountered enormous challenges, some have good prospects for the application of advanced manufacturing technology and design methods have emerged. Using information filtering technology and computer networks can realize the exchange and sharing of product design information perfectly, improving design efficiency and quality effectively, shorten product design and development time and win the market competition ultimately.The work of the thesis is on the basis of information filtering system that presented by our workgroup, so the author mainly do research on some key technologies related to the system. Firstly, the author bettered the information filtering system based on cooperative design;Secondly, for the disfigurement in information integration resources of product design and the lack of unified standards, the author solved the problem preliminary by using XML and data integration solution;Thirdly, the reliability of information filtering system designed to affect of indicators analyzed and evaluated using integrated vague law to assess its reliability;Finally, network environment is also important to the products information security. Therefore, the author finally design and built the network information security technology architecture, and built information management system security framework based on password technology in product design.
