【摘要】：随着全球化市场的形成和信息技术高速发展，产品的更新周期日趋缩短，产品创新速度也越来越快，企业竞争的焦点集中于如何才能更好地满足个性化的客户需求。在不牺牲企业经济效益的前提下，根据客户要求进行个性化的生产，提高产品创新能力已成为企业获得和保持竞争优势的一个重要方面。为了在尽可能小的产品差异下向市场提供尽可能多样化的产品，于是产品平台和产品族这些概念被提出，以有效地满足大范围的客户需要。而产品平台是产品族设计的核心内容，合理地构建产品平台是提高产品设计可适应能力的关键，面向大规模定制与产品平台战略等技术，模块化设计又是一种有效的设计方法。本文首先结合公理设计与设计结构矩阵，利用独立公理进行产品功能划分，建立产品设计矩阵，再结合设计矩阵与设计结构矩阵，构建产品设计关联矩阵，再利用可拓聚类算法对该关联矩阵进行聚类运算，以此来完成产品设计的模块划分。接着在划分模块的基础上阐释了平台策略的涵义，总结了产品平台概念的演变过程，在综合分析市场和技术不确定性以及产品平台开发复杂性的基础上，论证了产品平台规划是基于平台策略的产品开发的重要内容；然后在总结国内外学者提出的产品平台理论的基础上，，提出了一种产品平台构建方法：将以公理设计为指导框架，以功能需求分析为出发点，提出了一种产品平台设计新方法。该方法借鉴Kano模型，从用户需求的角度，利用独立公理将产品功能要求分为基本功能要求、期望功能要求和附加功能要求；然后基于公理设计原理，将产品功能要求映射为产品设计参数，建立设计矩阵；通过分析设计参数与各类功能要求之间的影响，构建产品设计关联矩阵，利用可拓聚类算法对设计关联矩阵进行聚类运算，将实现产品族基本功能要求的模块定义为公用模块；在此基础上，通过分析设计参数的灵敏度来选择公共平台参数，利用聚类分析以规划它们在产品平台中的共享策略。最后通过汽车内饰生产线滑板输送设备的应用实例验证了上述方法的可行性。
[Abstract]:With the formation of global market and the rapid development of information technology, the renewal cycle of products is shortened day by day, and the speed of product innovation is becoming faster and faster. The focus of enterprise competition is on how to better meet the needs of individual customers. On the premise of not sacrificing the economic benefits of enterprises, individualized production is carried out according to the requirements of customers. To improve the ability of product innovation has become an important aspect for enterprises to obtain and maintain competitive advantage. In order to provide the market with as many products as possible under the minimal product differences. Therefore, the concepts of product platform and product family are proposed to meet the needs of a wide range of customers. The product platform is the core content of product family design. How to construct the product platform reasonably is the key to improve the adaptability of product design. It is oriented to mass customization and product platform strategy. Modular design is also an effective design method. Firstly, this paper combines axiomatic design and design structure matrix, uses independent axioms to partition product functions and establishes product design matrix. Then combining the design matrix with the design structure matrix, the product design correlation matrix is constructed, and the extension clustering algorithm is used to cluster the correlation matrix. Then it explains the meaning of platform strategy and summarizes the evolution process of product platform concept. Based on the comprehensive analysis of the uncertainty of market and technology and the complexity of product platform development, it is demonstrated that product platform planning is an important part of product development based on platform strategy. Then, on the basis of summarizing the theory of product platform put forward by domestic and foreign scholars, a product platform construction method is put forward: the axiomatic design will be taken as the guiding framework, and the function requirement analysis will be taken as the starting point. A new method of product platform design is proposed, which uses Kano model for reference and divides product function requirements into basic functional requirements by using independent axioms from the point of view of user requirements. Expected functional requirements and additional functional requirements; Then, based on the axiomatic design principle, the functional requirements of the product are mapped to the product design parameters, and the design matrix is established. By analyzing the influence between design parameters and various functional requirements, the product design correlation matrix is constructed, and the extension clustering algorithm is used to cluster the design correlation matrix. The module that realizes the basic functional requirements of the product family is defined as a common module; On this basis, the common platform parameters are selected by analyzing the sensitivity of the design parameters, and their shared strategies in the product platform are planned by cluster analysis. Finally, the feasibility of the above method is verified by the application of slide conveyer in automobile interior decoration production line.
