中文摘要: |
针对按订单设计(ETO)产品设计规模大、构件间关联关系复杂、配置知识难以组织与重用等特点,提出了一种基于案例库和遗传编程的ETO产品配置设计方法。通过分析客户个性化需求,构造代表ETO产品主体结构的产品功能树;建立包含产品结构性与过程性知识的案例库模型;制定导向进化规则,明确种群约束判定条件,利用遗传编程算法实现产品结构调整和参数优化;基于适应度函数,对产品设计方案进行适应性评判,最后得到符合客户要求的设计方案。在此基础上构建了ETO产品配置设计原型系统,并以堆垛机的配置设计为例,验证了该原型系统的有效性、合理性。 |
英文摘要: |
Aiming at the characteristics of large-scale engineer-to-order (ETO) product design, complex relationship between components, and difficulty in organizing and reusing configuration knowledge, an ETO product configuration design method based on case library and genetic programming is proposed. Construct a functional tree that represents the main structure of ETO products by analyzing the individual needs of customers; establish a case library model that includes product structural and procedural knowledge; formulate oriented evolution rules, clarify the constraint relationship between product structures, and use genetic programming algorithms to realize product structure adjustment and parameter optimization. Based on the fitness function, the product design plan is evaluated for adaptability, and finally the design plan that meets the customer’s requirements is obtained. On this basis, a prototype system of ETO product configuration design is constructed, and the configuration design of stacker crane is taken as an example to verify the effectiveness and rationality of the prototype system. |
