摘　　要：针对飞机设计流程建模中遇到的建模过程复杂,主观性强等情况,提出了基于协同模式的建模方法。从某飞机设计实践出发,结合以往设计经验,调查设计组织、设计流程、设计工具等方面,归纳现有协同模式。结合各个模式的应用场合,分析其特点和优缺点。在此基础上,提出借助协同关联网络进行建模。协同关联网络由各模式协同行为和对应设计对象连接而成。使用Petrinet的网射分析寻找协同关联网络中的重复/迭代过程,辅助建立简化的流程骨架。以此骨架为基础,增加附属信息形成通用设计流程模型。用例证明,该建模方法分离飞机设计专业知识和流程建模知识需求,降低建模难度,交互验证的中间信息和形式化的分析方法增加了建模过程的客观性。A process modeling method was raised based on the cooperative pattern in airplane design, aiming at the difficulty of complexity and enormous magnitude of airplane design process. Investigating design steps, tools and or- ganization of airplane design experienced, 3 cooperative patterns were summarized. Characteristics of each pattern were revealed in its application scene. Modeling method separates knowledge requirement of airplane and modeling with cooperative connection net. The net was built by linking design objects and cooperative activities of some pat- terns. Petri net analysis was introduced to find iterating portions in the net. Simplifying the net with folding iterating portions, leads to a skeleton of design process. Process model was built by adding incidental information to the skeleton. With a use case, the method was proven to be more objective and convenient.
