【Abstract】 With the development of science and technology which in turn prompts social progress, market competition is becoming increasingly stiff and market segmentation is becoming more exact and accurate. As a result, the competition among various manufacturing firms is focused on how to meet diverse customer demands, faster and better. Therefore, in order to obtain a greater space to survive and prosper, production pattern of the corporation is bound to shift to Mass Customization (MC) mode. Then how to research into design reuse based on computer technology and how to investigate the implementation and control process of products so as to facilitate the rapid design and development oriented towards MC, reduce the cost, and improve the reliability and quality of products in the digital and network environment become the prime problems which confront modern design technology.This dissertation focuses on how to materialize products’ rapid response to design from the angle of design for mass customization. Using the design for components of numerical control machines as an example, this paper researches into some crucial technologies employed to achieve Rapid Response Design (RRD) of mechanical products.Major contents of the dissertation include:(1) Defining the concept of rapid response design system (RRDS) oriented to MC, summarizing main content and implementation strategies of the rapid response design for mechanical products, proposing to implement rapid response design of mechanical products based on Teamcenter Engineering (TCEng) Product Lifecycle Management (PLM) platform, constructing the framework of rapid response design system based on the PLM software and analyzing its key technologies and workflow.(2) Studying the modeling and implementation technologies of variant design of product family based on the main model technique, developing a new collaborative version management model based on the polychromatic sets to satisfy the demands of hierarchical version management in the process of rapid response design; With the Generic Bill of Material (GBOM) main model technique of product family, a hierarchical parametric master model of product is constructed, and the variant design and configuration management of linear motion rolling guide are achieved to verify the correctness of model.(3) Establishing a knowledge classification system for rapid response design of product, employing CBR and RBR integrated reasoning mechanism to obtain the knowledge of product design examples and rules. As a result, the efficiency of the knowledge base retrieval is considerable. Furthermore, based on the combined weights method, a similarity-calculated model of non-affirmative coefficient distance method for cases base retrieval is developed, and its validity and rationality are expressed by the searching examples of case library of machine tool.(4) Based on the task decomposition model of a typical machine tool product for its rapid response design, proposing the task allocation strategy of RRD across the enterprise and then establishing the task allocation model for the variant design of machine tool. Based on this model, the mapping from task sets to staff sets during the process of the modular machine tool design is achieved, and thus the task allocation problem of RRD between the tasks and teams can be solved efficiently. On the basis, this paper considers time, quality and cost factors which impact the design task allocation, adopt the fuzzy analytic hierarchy process (AHP) to select the best design team (staff), and the results are in accordance with the fact.(5) Studying the Data compression technology based on the extensible virtual world description language (XVL), proposing and constructing the framework for Enterprise Application Integration and Streaming Scheme on the basis of XVL sharing model. Furthermore, a collaborative design management prototype system based on the XVL is developed to achieve the collaborative browsing and markup of product 3D model.(6) Discussing the ways and means to implement mechanical product rapid response design based on TCEng product lifecycle management platform, together with some application examples.更多还原
