【摘要】：为了满足快速多变的顾客需求和不断细分的市场环境,产品族技术在飞机、汽车、船舶、电子产品、软件等行业得到了越来越广泛的应用,成为了实现大规模定制的有效方法和核心技术之一。在产品开发初期,将供应商选择问题集成到产品族设计中可以有效地节省生产成本、减少设计更改。本文在综述了国内外最新相关研究文献的基础上针对当前研究的不足,就集成供应商选择的产品族设计问题进行了深入研究,取得了一些重要的研究成果,且研究成果已发表和录用在多篇SCI国际期刊上。本研究的创新性研究成果主要包括以下几个方面：(1)建立了以最大化产品族市场利润、最小化产品族生产风险以及最小化供应商交货时间为目标的集成供应商选择的产品族设计方案评估模型和优化模型,从而使决策者可以根据其偏好和要求来从多角度对产品族设计和供应商选择的联合优化方案进行综合评估和筛选；(2)在集成供应商选择的产品族设计优化模型中,采用了条件分对数(Multinominal Logit, MNL)顾客选择规则来描述顾客选择行为,避免了传统确定性顾客选择规则的缺点,从而可以更精准地模拟顾客对产品的购买行为。同时,MNL选择规则也可以通过参数设置退化转变为确定性选择规则,这使得本文的优化模型更具准确性和普适性；(3)供应商往往会对产品零部件的报价采取一定的折扣政策来吸引企业购买其零部件,这种情况可能会影响到供应商选择的结果和产品族设计方案的选取。为了使本文的优化问题更符合实际情况,在上述建立的优化模型中考虑了供应商的部件报价折扣对集成供应商选择的产品族设计优化结果的影响：(4)针对本文建立的数学模型的特点,设计了NSGA-Ⅱ算法来对多目标优化模型进行求解。最后,结合实际应用案例对本文中的算法和模型进行了相关数值实验,并对实验结果进行了分析和总结,提供了一些有价值的管理启示。
[Abstract]:In order to meet the needs of customers and the market environment, product family technology has been more and more widely used in aircraft, automobile, ship, electronic products, software and other industries.It has become one of the effective methods and core technologies to realize mass customization.In the early stage of product development, the integration of supplier selection problem into product family design can effectively save production cost and reduce design changes.On the basis of summarizing the latest research literature at home and abroad, aiming at the deficiency of the current research, this paper makes a deep research on the product family design of integrated supplier selection, and obtains some important research results.And the research results have been published and employed in a number of SCI international journals.The innovative research results of this study mainly include the following aspects: 1) to maximize the market profits of product families.Product family design evaluation model and optimization model for integrated supplier selection with the objective of minimizing product family production risk and minimizing supplier delivery time.Therefore, according to their preferences and requirements, the decision makers can comprehensively evaluate and screen the joint optimization schemes of product family design and supplier selection from multiple angles in the product family design optimization model of integrated supplier selection.The conditional logarithmic Multininal Logitys (MNL-based) customer selection rules are used to describe the customer selection behavior, which avoids the shortcomings of the traditional deterministic customer selection rules and thus can more accurately simulate the customer's purchase behavior.At the same time, MNL selection rules can also degenerate into deterministic selection rules through parameter setting.This makes the optimization model of this paper more accurate and universal. Suppliers often take a discount policy on the price of product parts to attract enterprises to buy their parts.This situation may affect the selection of suppliers and product family design options.In order to make the optimization problem in this paper more in line with the actual situation,In the above optimization model, the influence of component quotation discount of supplier on the optimization result of product family selected by integrated supplier is considered. (4) in view of the characteristics of the mathematical model established in this paper,NSGA-鈪，
