【摘要】 为了满足用户个性化的消费需求，增强企业的竞争力，实现产品的定制生产是企业未来发展的趋势。现有基于虚拟现实的产品定制系统只能实现产品的外观定制(定制产品的颜色、材质等)，或者产品的选配型定制(从模型库里匹配出接近需求的产品)。本论文针对这种不足，从产品的变型定制、产品的定型定制两方面做了深入的研究。 基于产品的功能设计方法，对产品的功能要求进行描述，并结合Solidworks API二次开发技术，构建了一个基于可变参数的产品族实例；利用NIST开发包实现了VRMLToX3D转化模块，实时的生成用户定制的产品模型，实现了变型产品定制的功能。 研究了用户需求信息获取和处理的方法，使用中间件技术，实现了用户产品定制信息从功能参数到结构参数的实时转化；基于MVC架构思想，构建了系统应用框架，使变型定制部分的各个模块功能独立，由控制器来调控整个定制过程，使用户定制参数的获取、转化以及产品定制结果的输出自动完成。 选用X3D技术作为定制产品三维模型的显示方式，利用Java、VB编程技术，对X3D三维场景图进行操作，实现了定型产品定制功能，结合碰撞检测功能的运用，使用户在进行产品定制、产品浏览的过程中，有实时的交互性。 研究了基于Web的数据库技术，对基于JDBC的Web数据库技术进行了深入的分析；并结合网络与数据库技术，构建了一个基于J2EE的产品定制平台，实现了系统各个模块的信息集成；支持用户在网络环境下的可视化产品定制，实现了变型产品定制、定型产品定制、文件传输以及协同交流的功能，为解决产品定制所面临的问题提供了可行的技术方案。更多还原

【Abstract】 To meet customers’ diversification of consumption, enhance the competitiveness of enterprises, it is a direction for enterprises to implement the product customization production in future. Most of the customization systems, which are based on virtual reality, can only customize the product appearance, such as color, material etc, or match the appropriate product from library to meet the requirements. In this paper, variant and standardized customization methods are studied deeply to resolve the problem.The functional requirements of products are described by function design methods, and a product family based on variant parameter is constructed by Solidworks API technology. The VRMLToX3D component is implemented by NIST, customized products are produced in real time, and then variant customization function is realized.The method of acquisition and handling for the customers’ requirements information is studied; the information is processed by middleware, which changes the information from functional parameter to structural parameter. The system framework is constructed based on MVC method, which makes every component of variant customization part independent in function, the whole process of customization is controlled by controller, which makes acquisition and transformation of customization parameter and output of customization results complete automatically.X3D technology is used to show customized products in browser, and X3D scene is processed by Java and VB technology, which can customize standardized products. It is more real-time interaction to use collision detection function for the process of customization and browse.The web-based database technology is studied, and the JDBC-based web database technology is analyzed deeply; a product customization platform J2EE-based is constructed with web and database technologies; the integration of system components is implemented in the platform; the visual product customization on internet is also supported, variant and standardized product customization、 files transfer and collaborative communication functions are implemented, a feasible scheme to resolving the problem, which is in the process of product customization, has been presented.更多还原
