摘　　要：针对协同工作模式下传统飞机设计任务分解和过程建模方法存在任务关联语义不明确和复杂流程分析能力弱的不足,提出了一种基于任务关联WBS(Work Breakdown Structure)/Petri网的飞机总体布置设计过程建模方法。在飞机系统WBS基础上,采用可选、必选、选择、因果顺序、协调反馈等五种关系建立任务关联WBS模型,再映射成基于Petri网描述的飞机总体布置设计过程模型,实现飞机总体布置设计任务的静态结构表达和动态流程分析,使得任务分解和过程建模融为一体。通过建立飞机总体布置与协调系统对某飞机总体布置实例进行验证,证明了方法的正确性、有效性和适用性。To tackle the problems not having explicit semantics and powerful analysis ability of the traditional task decomposition and process modeling methods for airplane design in the cooperative development mode, an airplane general arrangement process modeling method based on task-related WBS and Petri nets is presented. On the basis of airplane system WBS, the TR-WBS model is built by using five constraint relations including optional, mandatory, choice, precedence, and feedback. By mapping the airplane general arrangement process model into a Petri net based model, the static structure description and dynamic analysis of airplane general arrangement design tasks is obtained, and the integration of the task decomposition and the process modeling is realized. The correctness, effectiveness and applicability of the method are verified through the established airplane general arrangement and coordination system.
