Abstract
Civil aircraft customer service is the full support of the main manufacturer from the perspective of customer needs, aircraft performance, and the interests of related parties during the product life cycle. Its data model can coordinate business and data between stakeholders, and provide a framework for business information representation and operation for customer data integration. In order to enable civil aircraft customer service to improve customer satisfaction and meet the development needs of the civil aircraft industry, it is necessary to establish a complete customer service system and form a common customer service business data model. Firstly, the S-series of integrated logistic support(ILS) specifications and ISO 10303-239 PLCS are interpreted to explore the ILS business interface relevance between international specifications. Then, the tools used to establish the customer service business model and data interaction of civil aircraft are sorted out, and how to use them is explained. Finally, the system is constructed from the three levels of civil aircraft customer service requirements, indicators and activities, combined with model tools to build a civil aircraft customer service business data model based on the S-series ILS specifications. This paper provides guidance for realizing the data circulation of various business links of customer service, and provides a basis and method for ensuring the safe operation of aircraft, reducing user operating costs and promoting customer service levels.

Summary
关 键 词:S 系列 ILS 规范;ISO 10303⁃239 PLCS;民用飞机;客户服务;数据模型 中图分类号:V267 文献标志码:A 文章编号:1000⁃2758(2021)03⁃0576⁃10 数据是信息的载体,是描述客户服务中发生的 业务过程的客观事实的集合。 如何描述数据使其可 在客户服务中具有通用性, SX002D 提供了所有S 系列 ILS 规范的统一最终状态通用术语 / 模型。 对 于 S 系列 ILS 规范,SX002D 通用数据模型( common data model,CDM) 是 2 个或多个 S 系列 ILS 规范共 有的所有数据元素的概念性描述。 该规范协调在相 应 S 系列 ILS 规范内执行的数据建模活动,并使用 统一建模语言( unified modeling language,UML) 将数 据需求整合为一致的 S 系列数据模型。 为了确保 S 系列 ILS 规范的使用者在 UML 的理解上保持一致, SX004G 通过对 UML 的类模型、数据类型、属性等说 明,对阅读和使用 UML 模型提供了清晰的指导。 为 了使数据在整个 ILS 活动内都具有通用性,除了对 数据的描述进行定义,还需要对数据间管理和交换 进行明确说明。 因此,SX005G 定义了使用 S 系列 ILS 规范时用于系统之间管理数据交换的规则,即 XML Schema。 1.2 ISO 10303⁃239 PLCS 规范业务流程。 SX005G 定义了用于管理通过 2 个 系统之间的更新消息交换的数据的规则。 定义为 XML 文档的交换文件在 S 系列 ILS 规范中称为消 息,消息对于接收系统有 2 种数据,分为新的数据和 已接收数据的更新。 数据的变更通过 UML 类业务 对象的动作类或标识代码( action / crud) 进行表示。 缩写 crud 代码是关系数据库应用程序中需要考虑 实现的所有主要功能。 首字母缩写词中的每个字母 都可以映射到标准结构化查询语言( structured query language,SQL) 语句,如表 2 所示。 需要注意的是接 收系统负责处理发送系统创建的更新消息,如果接 收数据系统的数据独立于发送系统数据更新过程进 行更新,则发送系统创建的消息( 数据值或元素操 作代码) 可能无效。
