【摘要】：产品族是企业为满足客户多样化需求而产生的一种规模化和定制化的生产方式。在产品族的整个价值流程中,设计阶段决定了70%-80%的产品成本和特性,具有重要的地位与作用。迄今,在设计学领域研究中,公理化设计理论是最经典影响也最大的设计理论,它是由美国麻省理工大学的Nam Suh教授提出的。在以往对产品族设计的优化研究中,主要是普通单层的优化研究,而产品族的设计过程决定了其优化问题往往具有层次和主从关联关系。鉴于此,本文基于公理化设计理论和双层规划理论,对产品族的设计域进行主从关联优化研究。通过对产品族设计域的优化问题及其主从关联进行分析,建立了产品族设计域的主从关联优化模型,最后通过对模型算法及优化评价的研究,检验了产品族设计域优化设计的可行性与经济性。首先,本文对产品族四个设计域各自需要优化的问题及其之间的主从关联关系进行了分析,并以典型设计域的优化为例,详细阐述了产品族设计过程中需要优化解决的问题。其次,在对产品族设计域优化的理论分析基础上,提出了产品族设计域主从关联优化的一般模型,并对应上章节中的典型问题,建立了其对应的主从关联优化模型,最后以鼠标的设计问题为例,对优化模型进行了应用研究。最后,研究了主从关联优化模型的算法及产品族设计域优化方案的评价系统。针对文中建立的主从关联优化模型,提出了模型的求解方法,同时在综合考虑客户满意度和企业利益的基础上,建立了产品族设计域优化的评价方法,从而为获得满足客户和企业利益的最佳设计方案提供了判断的依据。
[Abstract]:Product family is a kind of large-scale and customized mode of production produced by enterprises to meet the diversified needs of customers. In the whole value process of the product family, the design stage determines 70-80% of the product cost and characteristics, which plays an important role. Up to now, axiomatic design theory is the most classical and most influential design theory in the field of design. It was put forward by Professor Nam Suh of Massachusetts Institute of Technology (MIT). In the past research on optimization of product family design, it is mainly the general single-layer optimization study, and the design process of product family determines that the optimization problem often has the relation of hierarchy and master-slave. In view of this, based on axiomatic design theory and bilevel programming theory, the design domain of product family is studied by master-slave association optimization. By analyzing the optimization problem of product family design domain and its master-slave association, the master-slave association optimization model of product family design domain is established. Finally, through the research of model algorithm and optimization evaluation, The feasibility and economy of optimal design in product family design domain are tested. First of all, this paper analyzes the problems that need to be optimized in each of the four design domains of the product family and the relationship between the principal and subordinate. Taking the optimization of the typical design domain as an example, the problems that need to be solved in the process of product family design are elaborated in detail. Secondly, based on the theoretical analysis of product family design domain optimization, the general model of product family design domain master-slave association optimization is put forward, and the corresponding master-slave association optimization model is established according to the typical problems in the previous chapter. Finally, the application of the optimization model is studied by taking the mouse design as an example. Finally, the algorithm of master-slave association optimization model and the evaluation system of product family design domain optimization scheme are studied. In this paper, the method of solving the model is put forward, and the evaluation method of product family design domain optimization is established based on the comprehensive consideration of customer satisfaction and enterprise interests. Thus, it provides the basis for obtaining the best design scheme to satisfy the interests of customers and enterprises.
