基于构型项的飞机研制建模技术

Modeling technique of aircraft development based on configuration item

飞机制造业的业务过程是一个复杂的、动态的、数据量大的系统工程.如何建立简单完整的产品研制模型一直是业务过程优化(BPI,Business Process Improvement)中的难题.通过借鉴波音公司关于飞机构型管理和产品结构模块化的相关思想,强调构型管理技术在飞机研制的全生命周期过程中的重要性,明确构型项(CI,Configuration Item)准确的数学定义.依据构型管理简化产品的信息模型和Petri网(PN,Petri Net)描述、优化产品过程模型的特点,将Petri网理论与构型项结合起来保证全生命周期过程中飞机研制模型的一致性和完整性.提出CI-PN模型来描述整个飞机研制的信息和过程模型,并给出对翼盒研制过程模型描述、分析和优化的实例.

Business process of aircraft manufacturing industry is a dynamic and complicated system engineering with that the quantity of data is huge. How to build product development module simply and perfectly is always a difficult problem in business process improvement （BPI）. The importance of configuration item （CI） technology was emphasized in the lifecycle of aircraft development and the accurate mathematics definition was confirmed referring to Boeing company ideas about aircraft configuration management and the module of product structure. Then, two technologies of configuration management and Petri net （PN） were used to make the product information module simply and the product process module more perfectly. CI and PN were combined based on the two technologies to ensure the consistency and integrity of aircraft development module in product lifecycle. At last, the CI-PN module was proposed to describe the information module and the process module of the whole aircraft development process. The case to describe, analyze and optimize the module of developing the wing-box was given.
