【摘要】 数字化管理是航空企业应用数字化技术、加快企业信息化进程的一个重要方面。面对航空企业在实施企业信息化应用系统尤其是ERP的过程中,实施的成功率不高这一现实情况,本文在调研和分析航空企业实施企业信息化经验教训的基础上,结合航空企业的实际需求,在国防基础科研项目和江西省主要学科学术和技术带头人培养计划项目支持下,以航空企业数字化模型、模型驱动和数字化管理为主线,深入研究了航空企业管理中数字化驱动技术。本文的主要研究成果如下:1.提出了基于过程工程的航空企业建模技术。结合航空企业的特点,改进了原来的四元组企业模型,建立了六元组航空企业模型,并定义了企业模型描述语言,实现了企业模型仿真与优化。这是在航空企业管理中运用数字化驱动技术的前提。2.研究了基于过程建模的航空企业ERP配置技术。在深入分析航空企业ERP系统结构的基础上,从功能、数据、功能与数据的关系以及权限四个方面研究了ERP系统的可配置性,提出了基于过程建模配置ERP系统的方法。这是在航空企业管理中运用数字化驱动技术实施ERP的主要技术基础。3.提出了企业模型与ERP系统的映射元模型。在应用系统功能最小化的基础上,给出了企业模型到ERP系统的映射信息和规则,包括功能单元的映射、数据的映射、数据与功能单元间关系的映射以及权限映射。这是在航空企业管理中运用数字化驱动技术实施ERP的主要技术手段。4.研究了过程建模与ERP系统的集成技术。提出了基于过程建模配置ERP的集成框架和企业模型文件的解析算法,实现ERP系统功能单元的组装、输入输出数据以及系统属性的自动配置。这是在航空企业管理中运用数字化驱动技术实施ERP的集成环境和算法流程。在以上研究的基础上开发了基于过程建模配置ERP的集成系统,已应用于某大型航空企业型号工程中,在L15高级教练机和某型基础教练机的研制与生产中实施验证,缩短ERP实施周期30% ,取得了明显的综合效益,大大地推进了企业信息化进程,提高了企业应变能力。本文研究的航空企业管理中数字化驱动技术为ERP实施提供了一条有效途径,也可推广应用于PDM等数字化管理系统的实施。
【Abstract】 Digital management is one of the important factors for aviation enterprises to apply digital technology and quicken implementation of the informationization. However, most aviation enterprises often encounter failures while implementing application systems in enterprise information, especially ERP systems. Summing up the experiences and lessons and analyzing the requirements of domestic aviation enterprises, a digital driven technology in aviation enterprise management is investigated deeply, which includes digital model, model drive and digital management. The study is supported under the National Defense Scientific Research and Project Plan for Leading Subject and Academy Chief Scientist of Jiangxi Province. The achievements are summarized as following:1. An aviation enterprise modeling technology based on process engineering is put forward. Improving the 4-tuple enterprise model, an aviation enterprise model expressed in 6-tuple is built based on the characteristics of aviation enterprises. Besides, an enterprise model description language is defined to simulate and optimize the enterprise model. All these are primary for aviation enterprises to apply digital driven technology in enterprise management.2. An ERP configuration technology of aviation enterprises based on process modeling is studied. Considering the structure of ERP systems, configurability of ERP system is researched from four aspects, including functional cells, data, the relationships between functional cells and data and authorization. Furthermore, an ERP configuration method based on process modeling is presented. All these provide technical supports for aviation enterprises to implementation of ERP by digital driven technology in enterprise management.3. A mapping meta-model between enterprise model and ERP system is proposed. Based on the function-minimized technology of application system, mapping information and mapping rules from enterprise model to ERP system are given, which include mapping from enterprise model to functional cells, data, the relationships between functional cells and data and authorization of ERP system. All these offer technical methods for aviation enterprises to implement ERP by digital driven technology in enterprise management.4. Integrated technology between process modeling and ERP system is studied. Integration framework of ERP configuration on process modeling and parsing algorithms for enterprise model files are put forward so that functional cells of ERP system can be assembled and import data, export data and attributes can be configured automatically. All these accommodate an integrated environment and an algorithm process for aviation enterprises to implement ERP by digital driven technology in enterprise management.According to above, an Process Modeling Configuring– ERP Integrated System has been developed. The achievement has been applied in the development and production of L15 advanced training plains and a rudimentary training plain in an aviation enterprise, which results in 30% reduction of practice turnround. All these give an impulse for aviation enterprises to quicken informationization process and improve the responsiveness to changes. The digital driven technology in aviation enterprises management provides an effective approach for implementing ERP systems as well as other digital management systems.
