【摘要】：目前,产品族设计已经成为企业开发与制造的重要环节,优化的思想与技术是产品族设计中的重要基础与核心框架。以往对产品族设计的相关研究,主要是局限于产品域中的优化问题。而供应链作为产品族设计过程的重要影响要素,它不仅在设计过程的后端影响产品族的成本水平,而且在设计过程的前端影响产品族的模块化结构布局。因此,供应链与产品族设计过程的关联优化是决定产品族成败的一个关键性问题。本文首先对产品族设计过程进行分析,研究产品族设计中可能受到供应链因素影响的不同阶段,对结合供应链的产品族设计的主从关联优化问题进行一般性描述,提出解决这类问题的一般数学模型。针对具有产品族特点的双层数学模型提出有效求解的嵌套式遗传算法,最后详细研究了产品族设计与供应链联合考虑的几个典型问题与具体模型,通过案例验证文中提出模型与求解方法的有效性。论文具体的工作包括:第一、本文通过分析产品族设计过程与供应链过程相互关联考虑的分析,建立结合供应链的产品族设计优化的主从关联与主从结构的研究视角。第二、针对结合供应链因素的产品族设计主从优化双层模型的特点,提出了能够有效求解的嵌套式遗传算法。第三、针对产品族设计过程中的架构阶段与配置阶段分别考虑供应链的影响。在考虑供应链的产品族协同架构的优化设计中,基于产品族与供应链协同架构符合Stackelberg对策理论角度,构建产品族架构与供应链协同优化的混合0-1非线性双层规划模型:模型的上层决策产品族的整体布局即模块选择与组合结构;下层决策与上层配置相匹配的简易供应链架构设计。针对考虑供应链因素的产品族配置的研究中,将供应链看做一个整体构建结合供应链设计的产品族模块配置优化双层模型。针对基于工艺多样性而产生的产品族,在单一企业内部研究并建立了产品族与工艺配置的主从优化模型的。第四、以具有广泛应用的变压器、发电机和纪念台钟为例,验证了本文提出的方法框架、模型与计算方法的合理有效性。
[Abstract]:At present, product family design has become an important link in enterprise development and manufacturing. The idea and technology of optimization is the important foundation and core frame of product family design. As an important factor of product family design process, supply chain not only affects the cost level of product family in the back end of design process, but also affects the cost of product family. Therefore, the optimization of the relationship between the supply chain and the product family design process is a key problem that determines the success or failure of the product family. This paper studies the different stages of product family design that may be affected by supply chain factors, and describes the master-slave association optimization problem of product family design combined with supply chain. In this paper, a general mathematical model for solving this kind of problems is put forward, and an effective nested genetic algorithm is proposed to solve the bilevel mathematical model with the characteristics of product family. Finally, several typical problems and specific models of product family design and supply chain are studied in detail, and the validity of the model and solution method is proved by case study. The main work of this paper is as follows: first, In this paper, by analyzing the correlation between product family design process and supply chain process, we establish the research perspective of master-slave relationship and master-slave structure of product family design optimization combined with supply chain. In view of the characteristics of the two-layer optimization model of product family design based on supply chain factors, a nested genetic algorithm is proposed to solve the problem effectively. Third, The influence of supply chain is considered in the framework stage and configuration stage of product family design. In the optimization design of product family collaborative architecture considering supply chain, the product family and supply chain collaborative architecture accord with Stackelberg game theory. The mixed 0-1 nonlinear bilevel programming model of product family architecture and supply chain coordination optimization is constructed: the overall layout of the upper layer decision product family is module selection and combination structure; The simple supply chain architecture design, which matches the lower level decision and the upper layer configuration, is used in the research of product family configuration considering the supply chain factors. Consider the supply chain as a whole to construct a two-layer model of product family module configuration optimization combined with supply chain design. The. 4th optimization model of product family and process configuration is studied and established in a single enterprise. Taking transformers, generators and commemorative clock as examples, the proposed method framework is verified. The reasonable validity of the model and calculation method.
