现实系统认知上的复杂性和仿真过程中的计算复杂性,导致复杂工程系统的建模与仿真方法不同于一般工程系统.根据复杂工程系统设计、管理与施工的一般习惯,运用虚拟仿真技术,将建模仿真过程分为面向不同层次工程施工管理人员与施工操作技术人员的结构化任务建模和面向仿真技术人员的模块化实体建模2大阶段.分阶段面向不同层次管理需求的建模方法,降低了复杂工程系统虚拟施工过程建模的复杂度,所得模型能更真实地反映工程系统的实际施工过程,提高了建模和仿真效率.%The cognitive complexity for actual systems and the computational complexity for simulation processes,led to the complex engineering system modeling and simulation methods different from general engineering systems.Based on the general habits for complex engineering system design,management and construction,modeling and simulation process were divided into two different stages through the virtual simulation technology;one was the structured task modeling stage oriented engineering executives and construction technicians,the other was modular entity modeling stage oriented simulation technicians.The results showed that the complexity of virtual construction process modeling approach oriented different levels of personnel was reduced,and the model became more realistic response to the actual engineering systems construction process,the efficiency of modeling and simulation was also improved.
