The product family assembly line (PFAL) is a mixed model-assembly line, which is widely used in mass customization and intelligent manufacturing. The purpose of this paper is to study the problem of PFAL, a flexible (evolution) planning method to respond to product evolution for PFAL, to focus on product data analysis and evolution planning method.,The evolution balancing model for PFAL is established and an improved NSGA_II (INSGA_II) is proposed. From the perspective of data analysis, dynamic characteristics of PFAL are researched and analyzed. Especially the tasks, which stability is considered, can be divided into a platform and individual task. In INSGA_II algorithm, a new density selection and a decoding method based on sorting algorithms are proposed to compensate for the lack of traditional algorithms.,The effectiveness and feasibility of the method are validated by an example of PFAL evolution planning for a family of similar mechanical products. The optimized efficiency is significantly improved using INSGA_II proposed in this paper and the evolution planning model proposed has a stronger ability to respond to product evolution, which maximizes business performance over an effective period of time.,The assembly line designers and managers in discrete manufacturing companies can obtain an optimal solution for PFAL planning through the evolution planning model and INSGA-II proposed in this paper. Then, this planning model and optimization method have been successfully applied in the production of small wheel loaders.

产品族装配线(PFAL)是一种混合模型装配线,广泛应用于大规模定制和智能制造。本文的目的是研究PFAL问题,一种响应PFAL产品进化的灵活(进化)规划方法,重点研究产品数据分析和进化规划方法。提出了改进的 NSGA_II (INSGA_II)。从数据分析的角度,研究分析了PFAL的动态特性。尤其是考虑稳定性的任务,可以分为平台任务和个体任务。在INSGA_II算法中,提出了一种新的基于排序算法的密度选择和解码方法,以弥补传统算法的不足。该方法的有效性和可行性通过一个类似机械产品系列的 PFAL 演化规划实例得到验证。使用本文提出的 INSGA_II 显着提高了优化效率,并且提出的演化规划模型具有更强的产品演化响应能力,从而在有效时间段内最大化业务绩效。,离散制造公司的流水线设计人员和经理可以通过本文提出的进化规划模型和 INSGA-II 获得 PFAL 规划的最优解。随后,该规划模型和优化方法已成功应用于小型轮式装载机的生产中。使用本文提出的 INSGA_II 显着提高了优化效率,并且提出的演化规划模型具有更强的产品演化响应能力,从而在有效时间段内最大化业务绩效。,离散制造公司的流水线设计人员和经理可以通过本文提出的进化规划模型和 INSGA-II 获得 PFAL 规划的最优解。随后,该规划模型和优化方法已成功应用于小型轮式装载机的生产中。使用本文提出的 INSGA_II 显着提高了优化效率,并且提出的演化规划模型具有更强的产品演化响应能力,从而在有效时间段内最大化业务绩效。,离散制造公司的流水线设计人员和经理可以通过本文提出的进化规划模型和 INSGA-II 获得 PFAL 规划的最优解。随后,该规划模型和优化方法已成功应用于小型轮式装载机的生产中。离散制造企业的流水线设计人员和管理者可以通过本文提出的演化规划模型和INSGA-II获得PFAL规划的最优解。随后,该规划模型和优化方法已成功应用于小型轮式装载机的生产中。离散制造企业的流水线设计人员和管理者可以通过本文提出的演化规划模型和INSGA-II获得PFAL规划的最优解。随后,该规划模型和优化方法已成功应用于小型轮式装载机的生产中。
