【摘要】：在日益激烈的市场环境下，随着客户需求的个性化和多样化的出现，传统的大批量生产方式已经不能满足企业的需求，大批量定制生产模式逐渐受到了企业的重视。然而，如何以较低的成本、快速的设计出客户满意的产品决定了企业能否在竞争中获胜的关键因素。产品配置作为大批量定制的主要组成部分，，是一种有效联系个性化客户需求与定制产品的手段，是解决上述问题的关键技术。本文针对大批量定制环境，对面向个性化需求的机械产品配置技术进行研究，主要包括以下几方面内容：本文首先对客户需求的特点、类型和获取方式进行了分析。在此基础上，采用模糊集理论对批量订单进行聚类和模糊转化，并将转化后的订单进行满意度计算与分析，实现了订单的规模化和客户的满意度最大化。建立了客户需求本体模型，使需求表达更为明确，为产品配置奠定基础。其次，分析了产品族的功能与结构，在此基础上，分别建立了产品族的功能模型与结构模型，并利用本体建模工具建立了产品族的本体模型，使产品族中各概念表达更为清晰，为产品配置奠定基础；在分析产品族更新原理的基础上，通过零件的相似性和零件的使用状态分析实现了产品族的更新，保证了产品族的稳定性，为提高配置效率打下了基础。最后，利用本体描述的需求域与产品族结构域之间的关联关系，将客户需求向产品族中对应的配置项进行映射，并建立配置规则进行规则匹配推理，确定配置项下的选配项，形成多个产品配置方案。利用理想解法对生成的配置方案进行评价并排序，将最接近客户需求的方案交与客户。此方法不仅提高了配置效率，降低了成本，而且提高了客户的个性化、多样化要求。通过减速器的配置过程进行了实例验证。
[Abstract]:In the increasingly fierce market environment, with the emergence of individuation and diversification of customer demand, the traditional mass production mode can no longer meet the needs of enterprises, mass customization production model has been gradually paid attention to by enterprises. However, how to quickly design a customer satisfaction product with lower cost determines the key factor of whether the enterprise can win in the competition. As the main component of mass customization, product configuration is an effective way to connect individual customer needs with customized products, and is the key technology to solve the above problems. Aiming at mass customization environment, this paper studies the configuration technology of mechanical products oriented to individual requirements, which mainly includes the following aspects: firstly, this paper analyzes the characteristics, types and acquisition methods of customer requirements. On this basis, the fuzzy set theory is used to cluster and fuzzy transform the batch order, and the satisfaction degree of the transformed order is calculated and analyzed, which realizes the scale of order and the maximization of customer satisfaction. The model of customer requirement ontology is established, which makes the requirement express more clearly and lays the foundation for product configuration. Secondly, the function and structure of product family are analyzed. Based on this, the function model and structure model of product family are established, and the ontology model of product family is established by using ontology modeling tool, which makes each concept express more clearly in product family. On the basis of analyzing the updating principle of product family, the update of product family is realized by analyzing the similarity of parts and the state of use of parts, which ensures the stability of product family and lays a foundation for improving the efficiency of configuration. Finally, by using the relational relationship between the requirement domain and the product family domain described by ontology, the customer requirements are mapped to the corresponding configuration items in the product family, and the configuration rules are established for rule matching reasoning, and the matching items under the configuration items are determined. A plurality of product configuration schemes are formed. The optimal solution is used to evaluate and sort the generated configuration scheme, and the solution closest to the customer's needs is handed over to the customer. This method not only improves the configuration efficiency, reduces the cost, but also improves the customer's individuation and diversification requirements. An example is given to verify the configuration process of the reducer.
