【摘要】：在当前大规模定制生产模式下,企业要不断以低成本、高效率为客户提供满足多样化、个性化需求的新产品。产品变型设计作为实现大规模定制的关键技术之一,能够在已有的产品实例基础上,通过重用企业现有的设计知识和生产资源,实现产品的快速定制。客户需求是企业进行产品设计制造的起点,满足客户需求是产品设计的关键,基于此本文提出了客户需求驱动的产品变型设计方法,对客户需求、变型设计方法、变型设计方案多目标规划、设计变更的影响进行了深入的研究,具体内容如下:(1)本文研究了客户需求的特征与分类,建立了以需求节点为基础的客户需求模板。针对不同类型的需求节点,定义了参数型、选项型需求节点的表达方式。构建了客户需求获取系统,从而实现了快速、准确地获取客户需求。(2)为实现客户需求驱动的产品变型设计,本文构建了以模块为基础的模块化产品族结构模型。研究了变型设计的技术体系,提出了变型设计的具体流程,运用模块化、参数化变型设计方法实现产品的变型设计。(3)为综合考虑多目标因素对变型设计方案的影响,本文提出了产品变型设计方案多目标规划。构建了以客户满意度、成本、交货期为目标的多目标规划模型,通过NSGA-II算法求解该模型,从而获得优化的产品变型设计方案。(4)本文提出了基于设计结构矩阵的设计变更影响分析方法,研究了变更操作对矩阵的影响,通过设计结构矩阵的优化重组,从而得到设计变更的影响。
[Abstract]:In the current mass customization production mode, enterprises should provide customers with new products with low cost and high efficiency to meet diversified and personalized needs. Product variant design, as one of the key technologies to realize mass customization, can reuse the existing design knowledge and production resources to realize rapid customization based on the existing product examples. Customer demand is the starting point of product design and manufacture in enterprises, and meeting customer demand is the key of product design. Based on this, this paper puts forward the method of product variant design driven by customer demand, the method of variant design for customer demand, and the method of variant design for customer demand. The multi-objective programming of variant design scheme and the influence of design change are studied. The main contents are as follows: 1) in this paper, the characteristics and classification of customer demand are studied, and the customer demand template based on demand node is established. For different types of demand nodes, the expression of parametric and optional demand nodes is defined. In order to realize the product variant design driven by customer demand, a modular product family structure model based on module is constructed in this paper. The technical system of variant design is studied, and the concrete flow of variant design is put forward. The modular and parametric variant design method is used to realize the variant design of product. This paper presents a multi-objective programming for product variant design. A multi-objective programming model, which aims at customer satisfaction, cost and delivery time, is constructed and solved by NSGA-II algorithm. In this paper, a design change impact analysis method based on design structure matrix is proposed, and the influence of change operation on matrix is studied. Thus, the influence of design change is obtained.
