摘要
针对繁忙机场的机坪运行过程进行建模,采用了自顶向下、模块化的建模思路和着色Petri网理论方法,将滑行道和机坪等活动区域离散化,建立机坪运行过程的Petri网基本网模型;针对航空器在繁忙机场机坪内的运行过程特征,对机坪内各交通模块进行精细化建模,采用基本网模型的精细化替代方法,得到机坪运行过程的全局着色Petri网模型。实例验证了改进的建模方法的有效性,证明改进的建模方法具有较强的可移植性,可快速构建大型繁忙机场机坪运行模型。
ABSTRACT：Aiming at the modeling the running process in busy airport apron, we used top-down theory, modular- ization theory and color Petri net theory. Apron and other activity zones were discretized, and basic Petri net model of apron running processes was built. According to the characteristics of busy airpoort apron running process, every a- pron traffic module was modeled elaborately. Using elaborate replace algorithm for basic net model, global color Petri net model for apron running process was obtained. Real examples verify the effectiveness of the improved method of building model, and prove that the improved method of building model has strong portability and can build the run- ning model for large-scale busy airport apron.
